Space Innovation and Mobile Healthcare

In today’s A Lab Aloft, our guest blogger is the Director of NASA’s Human Health and Performance Center, Dr. Jeffrey Davis. This center fosters a collaboration between space and Earth research and technologies. Dr. Davis shares with readers the potential behind cooperative efforts during the development stages of projects.

Mobile healthcare is the focus for the upcoming NASA Human Health and Performance Center, or NHHPC, Workshop, scheduled for June 7 in Washington, D.C., as part of D.C. Health Data and Innovation Week. This is our third workshop, and topics of interest include not only terrestrial global health issues, but also technologies for smartphone applications to collect data, to inform patients, to connect patients with their providers, etc.

For everything developed through the NHHPC, we would like to see an Earth and space application, as well as a transfer of knowledge in both directions. NASA technology could be adapted to terrestrial health issues, via spinoffs and other applications, but we hope to pull in ideas that exist in the public domain for the mutual benefit of everyone. That is the concept behind the center, to connect people and employ that bridge in both directions to benefit spaceflight and life on Earth.

While there are a number of projects ongoing between members, for this blog I am focusing on the Colorimetric Solid Phase Extraction, or CSPE, technology. This is a great example, because it’s different from flying a commercial off-the-shelf device on the International Space Station. It has the potential for development in more than one application.

The CSPE is a paint chip identification device originally designed to match paint colors. The technology was adapted, however, to measure silver and iodine in water and it is now flying on the space station for this purpose. Called the Colorimetric Water Quality Monitoring Kit, this tool enables the measurement of biocides found in water on orbit to allow for safe drinking water for the crew.

There are additional Earth benefits that could derive from the CSPE. It has the potential to be modified to measure arsenic and lead in water, which are global public health concerns. This other capability is not yet developed, but it is a great example of how an innovative design from a non-biomedical piece of equipment can have mutual space and Earth applications.

Through the NHHPC, we hope to find technology applications for space flight or that can use the space station as a testbed for evaluation in later flights. When we are able to fly technologies early in their development on station, we have the benefit of visualizing how the orbiting lab works as a platform for planning purposes.

The inverse of this is that as we continue to learn more about human adaptation to long duration space flight, we can expand that knowledge base through our member organizations and derive how existing NASA technologies or future technologies might adapt for Earth benefits. What we have found is that by approaching problem solving early enough with the NHHPC members, we can preemptively address issues or requirement questions. Creating a device that is low weight, low power and robust parallels many healthcare concerns, especially for remotely located populations.

We find that by asking the right questions, we can connect people in the early phases of technology planning and development. Technology sharing can always occur, but the goal is to identify common issues for use as collaboration platforms that can eventually turn into projects.

Remembering Janice Voss

The International Space Station Program Science Office would like to dedicate this entry of A Lab Aloft to the life and work of astronaut Janice Voss, who passed away February 7, 2012. Her support NASA’s vision for science on orbit was a remarkable contribution to our research mission.

Janice Voss, Ph.D., was an astronaut and mission specialist for five space shuttle missions, logging over 49 days in space. These were physical science flights, including STS-83 and STS-94, which were historic re-flights to achieve a singular microgravity research mission. Voss also flew the first “commercial” Spacehab and the radar mapping mission.

With a real love for physical sciences, Voss used her dedication to research to determine her next role as NASA transitioned from the shuttle era to the station era. Voss was the only crew member ever selected to serve as a Lead Increment Scientist to represent the research community during experiment operations. She worked in this role during Expeditions 8 and 9.  

“Her boundless enthusiasm for getting as much research done was contagious, especially welcome in the challenging time after Columbia,” remembers John Uri, her manager in the ISS Payloads Office at the time. “Her experiences from flying science missions as an astronaut were invaluable in optimizing the onboard research.”

The timing of her tenure, which followed the Columbia tragedy, led to one of the more interesting things that happened while Voss was Lead Increment Scientist. While the shuttle was grounded, researchers proposed experiments that could be done with existing materials on orbit.

The International Space Soldering Investigation, or ISSI, was one of these studies performed in microgravity. The crew used the soldering materials they had on orbit to make coupons and melt them, which led to an amazing result! The rosin that was in the solder boiled out to the outside of the coupons, orbiting around them.

I remember how excited Janice was about this new finding. She worked with scientists to evaluate what caused the orbital effect, with the final determination pointing to Marangoni convection. Voss presented the results in a press briefing, including the incredible video of the experiment.

Later on, as Voss was assigned to different things in the Astronaut Office, she became the ongoing research representative for a number of years. There she represented the crew office, but always with the perspective she carried with her from her time as a Lead Increment Scientist, which made her viewpoint unique.

Voss had a natural scientific curiosity that prompted her to always try different things. She never accepted at face value how things worked, and would try alternatives to investigate further. This questioning nature was an exceptional attribute and helped to make her a success in her many roles with NASA.

Part of the Mission, Part of the Science

In today’s A Lab Aloft entry, guest blogger and European Space Agency astronaut Christer Fuglesang talks about his role as a test subject while living aboard the International Space Station.

You may not know it, but being an astronaut also means being a guinea pig. A lot of the research done in space is about humans, in particular how our bodies are affected by the weightlessness. This is important to know in order to prepare ourselves for future human exploration, like when we will travel to Mars. But this research also gives us many new insights in how our bodily systems work. This knowledge can help scientists and doctors to improve medical treatments here on Earth. They can even find new and better ways to prevent illnesses based on microgravity studies.

Virtually every astronaut that has ever gone into space has participated in medical experiments as a test subject – or as I like to call it, a guinea pig. The inhabitants of the International Space Station almost daily have some activity related to human research. During a workout, for instance, we take measurements like blood pressure, heart rate, or body temperature to provide valuable research data.

Some studies, like the Neuroendocrine and Immune Responses in Humans During and After Long Term Stay at ISS, or Immuno, require taking a saliva sample to check the immune system. Then there’s the Nutrition Status Assessment, or Nutrition, which requires blood and urine samples that store in the Minus Eighty Degree Laboratory Freezer for ISS, or MELFI, aboard the station. They later return to the ground for analysis. Another investigation that comes to mind is Bodies In the Space Environment: Relative Contributions of Internal and External Cues to Self – Orientation, During and After Zero Gravity Exposure, or BISE, which measures brainwaves while the astronaut performing some visual tasks to investigate how microgravity affects the neurological system.

It seems that almost every system in our bodies gets more or less affected by weightlessness: from muscles and bones to cells in the immune system, from the heart and lungs to eyes and the balance organs in the ears. Humans are designed to live in a 1-g environment, making their long-term exposure to microgravity a fascinating and biologically altering study of the entire body.

In my case, I have specifically participated in several experiments related to the balance system, or vestibular system, such as the Otolith Assessment During Postflight Re-adaptation, or Otolith, and the Ambiguous Tilt and Translation Motion Cues After Space Flight, or Zag. Before and after my flights, I stood on wobbling plates and sat in spinning and sliding chairs, trying to keep my balance or perform some set of actions.

Meanwhile, scientists observed me and compared my responses from before flight with how I performed right after about two weeks in weightlessness. They also looked into how my balance regained normality during the week after returning to Earth. This helped them to understand new things about how humans keep our balance. This  knowledge may eventually help doctors to better diagnose people who have medical disorders like disorientation and nausea.

In almost all science, doing an experiment one time is not enough. This is particularly true in human research, since each test subject is somewhat different. Therefore, some 10 other astronauts also performed the above-mentioned experiment. As one can understand, with only so many crew members on orbit at a given time, it takes awhile to get enough guinea pigs to complete a round of human research in space.

These studies are well worth it, however, as is the discomfort of sitting in a chair that spins with 400 rotations per minute while sliding sideways. The research is important and yields unique results for the benefits of humans, both in space and on Earth.

Christer Fuglesang

Christer Fuglesang is an astronaut with the European Space Agency, or ESA. He flew as a Mission Specialist with STS-116 and STS-128 to the International Space Station where he participated in multiple extravehicular activities, or EVAs. He is the first Swedish astronaut to fly in space.

Texas Talks Space

In today’s A Lab Aloft, Jessica Nimon, research communications managing editor for NASA’s International Space Station Program Science Office, talks about the impact of interacting with the public during Space Week 2013 in Austin, Texas.

Texas hosts Space Day at the Capitol in Austin every other year as part of Space Week. This year’s theme was “Human Exploration: the Journey Continues.” This was my second time representing the International Space Station Program Science Office to the students, members of the public and legislative staff who attended. I enjoy participating in such events because not only I can share the latest space station research and technology news, but it also gives me a chance to gauge perceptions from the audience I communicate with in my role as a writer and editor at NASA.

Keeping the exploration theme in mind, NASA’s International Space Station Program research and technology display shared a space with the agency’s Commercial Crew Program and Orion vehicle displays. Joining these exhibits in the lower level of the Capitol building’s rotunda were representatives from various commercial space companies, including SpaceX and Blue Origin. The in-the-round exhibit placement seemed symbolic of the partnerships taking place with NASA to continue and expand human space exploration.

My colleagues, Scientific Communications Analyst Amelia Rai and Research Scientist Chelsey Bussey, helped tell the story of the amazing research, technology and educational opportunities and developments from our orbiting laboratory. We shared how the space station is a resource that goes beyond space exploration goals, reaching out to cross boundaries in areas of healthcare, pharmaceutical advancements and industry spinoffs. Some of my personal favorites to highlight include NeuroArm, a lifesaving robotic instrument for brain surgery developed using technology from the space station’s Canadarm, and advances made in vaccine development.

The inspiration shared at such events has the potential to touch not only the 3rd to 8th grade students targeted by Space Day, but also to inspire the imagination of new users with research goals for microgravity research. While speaking with the people visiting our exhibit, at least one scientist expressed interest in how he could use the space station as a platform for his research.

One of the more frequent questions we received during the event had to do with NASA’s collaborative efforts with private businesses. Having our industry partners right next to us in the rotunda provided a great opportunity to share the way NASA does business. Visitors were surprised and excited to hear that NASA is working together with private companies to provide avenues for future exploration, as well as resupply and experiment sample return from the International Space Station.

Space Day followed on the heels of South by Southwest (SXSW), a multiday conference and festival highlighting music, film and technology, which also had a space-themed focus this year. Excitement for exploration was still abuzz all over Austin. Although we didn’t attend SXSW, Amelia, Chelsey and I did have our own follow-up activity by attending an Amateur Radio on the International Space Station (ARISS) event on March 20 at the Ann Richards School for Young Women Leaders in Austin. These students, who were not able to visit the Capitol for Space Day, were excited to have a more up close, personal connection with the space station.

Using a ham radio contact, which lasts for about 10 minutes, the 540 middle and high school girls were able to listen as their peers asked space-related questions directly to space station Commander Chris Hadfield, who answered from aboard the orbiting laboratory. The audience was so attentive you could hear a pin drop while Hadfield spoke!

Project Specialist Monica Martinez organized the ARISS event for the school and commented on the impact such an opportunity has on these young women. “The ARISS contact was an experience that truly wowed our entire student body, faculty and administrative team. The girls thought it was one of the best events of this entire school year and loved talking to Commander Hadfield. They were also so ecstatic to see that he had tweeted about our school right after the contact. Our students were inspired by his words and the overall experience.”

The event was followed by a short space station presentation by Amelia, who shared space station facts and talked about some of the benefits for humanity that have already derived from related research and technology. Amelia’s talk was followed by a short question and answer session where the students’ interest in space-related topics and careers was evident, showing a bright future for human endeavors with space research and exploration.

The International Space Station: Scientific Melting Pot

In today’s A Lab Aloft entry, guest blogger Assistant International Space Station Program Scientist Kirt Costello shares how the various science disciplines studied aboard the International Space Station can work in concert to enhance research goals.

By now, if you are a follower of this blog or just a follower of the International Space Station, you are familiar with the tremendous international effort it took to assemble this laboratory in orbit and bring its facilities up to their full potential. The contributions of 15 nations over the last decade have resulted in this unique resource with its access to the microgravity environment, stable viewpoints of Earth and space, as well as access to the orbital environment—namely radiation and the vacuum of space. But what does the cooperative environment that went into building the station mean for the long term science prospects that are now ramping up to their full potential?

The space station has become a scientific melting pot. Similar to the benefits that immigration brought to North America during the industrial revolution, the station is poised to provide benefits to the scientific community and any young pioneers willing to take up the challenge to use this outpost on the frontier of space. The station is also a U.S. National Laboratory, with research facilities that support human biomedical research, animal and plant physiology, materials science, fluid and combustion physics, remote Earth observations, and advanced engineering and technology demonstrations, side-by-side-by-side.

This multidisciplinary research facility presents a rare opportunity for researchers. The dedicated research facility is still much more common than the multidisciplinary facility, typically limiting researchers to just one field of scientific investigation.   Aboard station the experiments from these vastly different fields literally run right next to one another. The astronauts who make many of these investigations possible often have different scientific backgrounds from the principal investigators they are working with on the ground. This opens the potential for dialogue and insights as the studies progress.

The spirit of cooperation that was required in building the space station is still very much evident  today. Different investigations on board may cooperatively share equipment to accomplish their research objectives, minimizing the cost and mass to launch and maximizing the use of in-orbit resources.

One such example of resource sharing that is possible aboard station is in the sharing of camera equipment and software for the Binary Colloid Alloy Test (BCAT) and the Earth Knowledge Acquired by Middle School Students (EarthKAM). BCAT is a set of fluid physics experiments to examine the traits of super-critical fluids and phase separation of fluids. Meanwhile, EarthKAM is an educational outreach study focusing on remote Earth observation and using the capabilities of the EarthKAM camera to engage students, teachers and researchers in collaborative investigations. These two studies may seem worlds apart, but it is because the BCAT investigation is able to use the automated EarthKAM camera and software that BCAT was able to run many samples without requiring an undue amount of crew time.

So why is multidisciplinary research a good thing to promote? For one thing, it often leads to innovation. The explanation for this is something we’ve all experienced from time to time. It’s much like when you get stuck on a problem. You can stare at it for hour upon hour and just not see the solution. Yet if the right friend happens along, they might see something you’ve been missing and the problem is solved in next to no time. Frustrating, sure, but sometimes a different perspective is all that is needed to reach a breakthrough.

Multidisciplinary science tries to capitalize on the benefits of having different scientific backgrounds engage and become part of the solution to a complex problem. Admittedly, a physicist and a biologist may look at a problem and see vastly different solutions, but when multiple disciplines and multiple participants work together to solve the same problem it opens the doorway to true innovation.

A great recent example is the interaction between the BCAT-6 principal investigator Matthew Lynch and Expedition 30 crew member Don Pettit. Lynch and Pettit worked together to achieve a more detailed image of the BCAT phase separation sample. Pettit suggested using a laser pointer source on orbit to attempt to reveal any diffraction—when light bends around an object—patterns that showed the structures and phase separation characteristics they were looking for. It worked! Innovation was born at the intersection of fluid physics, optical physics and chemical engineering.

Concept for how diffraction patterns can be detected from suspensions of colloidal particles. Irregular diffraction patterns result from irregular particle spacing, however, the presence of the pattern allows you to know when the colloidal particle groups are within the field of the camera.

Co-location is another obvious advantage of the station as a research platform. To date there have been several investigations directed at in-house resource production, such as Tomatosphere, which run in the LADA greenhouse and the Biomass Production System (BPS), to name a few. Additionally there have been multiple experiments designed to help better understand the burning of fuels in the Combustion Integrate Rack (CIR) and the Microgravity Science Glovebox (MSG), like the FLEX-2, SPICE and SLICE investigations. As a result of such studies, crew members may someday grow their own fruits and vegetables to eat or be able to fuel up the engines of the future.

When multidisciplinary science is brought into this picture, you can envision not only growing food aboard station, but processing those plants into biofuel and then testing its combustion capabilities. The context evolves into a larger study of in-orbit biofuel suitability. In fact, just because these resources are all available on station, researchers can propose new multidisciplinary studies to spur on scientific innovation.

Another sign of the multidisciplinary research potential on station is the transformation of the American Society for Gravitational and Space Biology (ASGSB) into the American Society for Gravitational and Space Research (ASGSR). At the first ever ASGSR Annual meeting, held in December in New Orleans, researchers and students from a wide range of physical and biological sciences came together to discuss the possibilities and challenges of reduced gravity studies. The opportunity was an enlightening one for scientists in previously separated disciplines to come together and share information on their research programs, including many of the active areas of research done aboard station.

With collaborative efforts like these, the multidisciplinary research potential of the International Spaces Station is already being tapped. It will be exciting to see what discoveries will result from our orbiting, scientific melting pot in the years to come.

Kirt Costello completed a Ph.D. in Space Physics and Astronomy in 1998. While at Rice University, Costello worked on a magnetospheric forecast model used to predict the magnetic field response at the Earth’s surface based on upstream solar wind data. The model was used as a primary forecast model in this field at the Space Environment Center in Boulder, Colo., from 1997-2011. Since 2000, Costello has worked at NASA’s Johnson Space Center as a Thermal and Electrical Power Crew training instructor, as an International Space Station Training Lead, and as a group lead in the Mission Operations Directorate Operations Division. Kirt is now the Assistant International Space Station Program Scientist for National Research. In this position he works with the ISS Program Scientist to advise the ISS Program Manager on the objectives and priorities of science being prepared to fly to the space station.


The Tool to Fill the Gaps of our Senses: AMS

In today’s A lab Aloft blog entry, International Space Station Associate Program Scientist Tara Ruttley shares her point of view on the importance of asking the big questions via station research.

When I do public speaking events, people always ask me what’s my favorite investigation. For me it’s usually the Alpha Magnetic Spectrometer, or AMS investigation. This incredible instrument is a particle physics detector mounted to the outside of the International Space Station. The AMS was developed by Professor Samuel Ting, a Nobel Laureate in physics, along with an international collaboration of 16 countries organized by the U.S. Department of Energy.

Estimated distribution of dark matter making up 22 percent of the mass of the universe and dark energy making up 74 percent, with ‘normal’ matter making up only 0.4 percent of the mass of the universe. (NASA)

The goal of AMS is almost like sci-fi, involving the search for dark matter, dark energy, antimatter, and even something called strangelets. You hear about these things growing up and on TV and you wonder, is that real? If you go past the scientific jargon, the purpose of AMS is to answer a fundamental question in our nature. To ask, as we have from the beginning of time, how did the universe begin?

The answer to this question intrigues me, like everyone else, because it inevitably addresses “who are we and what are we doing here?” Everybody would love to know, so we seek the answers the best way that we humans can: pushing technology limits to find evidence in ways that our own human senses cannot.

The researchers behind AMS are trying to get solid data to support one of the more prevalent theories: the big bang. In a nutshell, this theory says that the universe came together, particles condensed, and boom! You got us. It’s a little more complicated than that, but the theory behind it is that for the big bang to even occur, you had to have equal parts matter and antimatter.

Matter is something we can see and feel, it’s all around us and makes up everything. It’s so very obvious! Antimatter is a little more tricky for us. It is the opposite of matter and we can theorize that it exists and even make small, fleeting samples in laboratories. And so we are using AMS to look for these things that we mere mortals aren’t capable of perceiving for ourselves.

AMS’s space shuttle-mounted predecessor actually found evidence of antimatter a few years ago, so we are only teased by this potential and are now prompted to capture the particles in greater, consistent amounts for study. Now we’re ready to collect lots of evidence for antimatter levels that will keep Nobel laureates, post-docs, and graduate students busy analyzing for years. Since its installation on station, which marked a one year anniversary on May 19, AMS has been collecting about a billion observations per month and even the smallest bits of data are going to lead to hundreds of publications. These will cite the importance of AMS findings with a relevance that likely only super smart astrophysicists will understand, and that the rest of us will see in headlines here and there as new evidence unfolds.

Using AMS, we record as much data as we can and analyze it here on Earth. This is where we try to tell an ultimate story with it. It’s what we do in science: chip away at a question until we can come to a conclusion that is always just beyond the next discovery. Yet, as exciting as the headlines will be, I actually tend to struggle with what’s next on these findings. I struggle because, since as we gain bits and pieces of knowledge, inevitably we learn not only what we didn’t know, but how much more there is to know.

Can you sense my impatience and excitement?

Observing antimatter is the first data goal that goes back to the big bang theory. The next data set AMS looks for is dark matter or dark energy, which is fun for me because it further proves that there’s more out there than meets the eye. We humans have senses for sight, sound, smell, taste, and touch, but we are limited to the capability of our receptors as we constantly take in our environment. We miss things that could be right there in front of us.

One of the limits of our eyesight, for instance, is that we can only see a certain spectrum of light. We don’t see the ghastly amounts of waves that pass all around us as our wireless devices talk to each other, or our radios blare during our morning jog. Our eyes see only 5 percent of the universe! We can sense that the other 95 percent of the universe exists, however, because we have found tantalizing evidence through research. We are using AMS as an extension of ourselves to fill in the gaps of our senses and help us understand the unknown. This includes the parts that we don’t even know we don’t know yet.

The starboard truss of the International Space Station is featured in this image, including the Alpha Magnetic Spectrometer-2, or AMS, at center left. (NASA)

AMS also is looking for evidence of a type of matter called strangelets. Yes, it does sound … well … strange. This would be a new form of matter that we have theorized existence of, but haven’t found in nature quite yet.

We’re taught in school that all matter is made of atoms, which we thought were the smallest form of matter. Now scientists are finding that atoms are made of even smaller quarks, and the prevailing theory regarding quarks is that there are six different types in the universe. We have classified all matter on Earth as being made up of only three types of quarks. So why does nature need the additional three? Some scientists theorize that there are other forms of matter out there that would be made up of a combination of these six quarks, and they’re calling them strangelets. It is a creative effort to try to answer what and where these strangelets are. Scientists have created such evidence as “strange” and “antistrange quarks” in heavy ion accelerators, which they theorize could lead to strangelet formation, but as of now, a strangelet is still a hypothetical particle. The prospects are endless.

Only the space station is capable of supporting the power and data transfer AMS requires to look for evidence of antimatter, dark matter, dark energy, and strangelets, and it will keep the scientific community busy for years. The human species develops tools like AMS to find the things we might otherwise miss, because we seek answers — lots of answers. It’s our nature.

AMS is an instrument that is taking it all in and ultimately it’s humans who will try to make sense of the information and apply it to what we know or think we know. We’ll learn what we didn’t know and try to tell our own local story. As we advance as a species, we build on that knowledge that may one day expand with the universe, beyond our little planet. It’s a good time to be a science geek.

A Slice of Time Pie

As NASA astronaut Don Pettit readies to return home from his mission aboard the International Space Station, he shares with A Lab Aloft readers the art of time management aboard the orbiting laboratory. Pettit’s blog entry was originally published on his blog, Letters to Earth: Astronaut Don Pettit, on June 22, 2012.

If my day on space station were a pie, it would be sliced into many wedge-shaped slivers.

It begins with a small slice for waking up, hygiene, and a bag of coffee (even in space, it is comforting to have a morning routine). This is followed by a slice for reviewing and organizing the tasks that will make up my work day. I might make a list of tools so that when I float to the tool box, I can gather everything I need in one trip. Then we have a morning conference with mission control.

Our work day then begins, consuming a 12-hour slice of time pie. At the end of the workday, we have another conference with mission control, followed by about an hour of work tying up loose ends. Then there is a slice for crew dinner. It is not unusual to work the whole day without seeing your fellow crew members at all (space station is a big place), and it is important to gather over a meal to exchange stories. This fulfills a very human social requirement, probably done since the discovery of fire, when the tribe would gather around the burning embers after the hunt (we now gather around our electric food warmer).

This leaves about a nine-hour slice of off-duty time until the whole routine begins anew. Note well that this is not “free time” but “off duty time”—a significant distinction when living on a ship, be it on the ocean or in space. Sleep comes in your off-duty time, and depending on how much you need, determines the size of the leftover slice of personal pie. All of us have families and friends, and if we want to gracefully return to our places on Earth at some point in the future, they require sharing a significant piece of your personal pie. At the end of the day, I am lucky to have an hour slice of truly personal time, often spent in the cupola gazing at the cosmos (writing these essays comes from this slice and competes with window time, which accounts for some of the delays between postings).

By far the largest slice of time pie is the 13-hour on-duty workday. Of this wedge, about 6½ hours is working primary mission tasks. These include scientific and engineering research, operational tasks such as flying the robotic arm and spacewalks, and spacecraft system maintenance/repair. The balance of the workday is spent on the necessary upkeep and overhead to enable the 6½ hours of time on task. This includes our 2½ hours of physical training (maintains crew health), transfer and stowage of new supplies from visiting —Progress, European ATV, Japanese HVT and the commercial vehicles, Dragon and (soon) Cygnus)—inventory and audits of existing supplies, managing our trash, conferences with mission control (some days we will spend 15% of our time talking to them), lunch, toilet, unplanned repairs (e.g. network, laptops, toilet, drinking water problems, etc.), and simply searching for needed items (often times not found in their proper place).

While achieving only 6½ hours work out of every 24 hours on mission tasks may seem appalling, it is commensurate with Earthly efforts when working in harsh frontier environments. When I was deployed with the Antarctic Search for Meteorites (ANSMET) team on a remote glacier field about 200 kilometers from the South Pole, we toiled for about 14 hours a day to enable 6 hours of our mission’s work; hunting for meteorites. A good slice of this Antarctic time pie (obviously a frozen dessert) was taken for such supporting tasks as snowmobile maintenance, gasoline stove fuel management, shoveling snow to keep our Scott tents from becoming buried, latrine maintenance, cooking and food management, melting ice for drinking water (a big time sink), drying sweaty clothing, and simply trying to stay warm. Considering the harshness of the Antarctic interior, it was fortunate we could spend six hours a day on the mission task. The same sorts of numbers are seen in deep ocean efforts, particularly if the divers are living under high-pressure, saturated gas conditions (pressurized living quarters that are at the same pressure as the equivalent ocean work depth). When humans venture into a harsh wilderness, the fraction of time on task shrinks while the effort to simply be there grows. In any of these settings, you are lucky to log six hours of mission tasking and six hours of sleep. The rest of the time is spent simply trying to stay alive.

On weekends we have off-duty time, but never a free weekend. On Saturdays, we are scheduled for six hours of on-duty time, mostly housekeeping duties where we vacuum filters and swab the decks. On Sundays, our lightest workload, we have about 3½ hours of tasking (this includes our 2½ hours of exercise). To date, we have had four weekends in a row where something came up that trumped our off-duty time. One was for an electrical failure in the ATV cargo ship that if uncorrected, would have required an emergency undocking with possible loss of all our new supplies. One was for a possible near collision with a piece of space junk, where we had to close all the hatches to make station “watertight” and then hide in our Soyuz spacecraft. Another was to fix the toilet after it failed, and one was for our regenerative water processor (the coffee machine). During this period we worked over 30 days without a break. When you go to the frontier, you are there to do something productive, not to sip tea and eat bonbons.

Organization is the key to using personal time effectively. I have a 5-, 15-, and 30-minute plan in my pocket, so when there is a pause in the mission work, I know exactly how to use the moment productively. Then, when you truly have a significant span of off-duty time, perhaps on a Saturday night, there is nothing more awe inspiring than floating for an orbit in the cupola and observing the Earth. My personal slice of time pie may be only a sliver, but oh, how sweet it is!

Putting on a Thinking Cap for Brain Research on the Space Station

In today’s A Lab Aloft, guest blogger astronaut Bob Thirsk shares with readers his perspective as a test subject for International Space Station investigations.

I operated many different science payloads during my six-month International Space Station expedition in 2009. Some payloads only required me to power up and check out the hardware. Once activated, either automated software or the ground science team took control of payload operations and completed the rest of the experiment.

Neurospat, on the other hand, was a payload that fully engaged me in the science and data collection. A cognitive function experiment from Belgium and Hungary, it depended on astronauts to operate all aspects of the experiment from start to finish and even to serve as experiment test subjects. As a fundamental neuroscience research investigation, Neurospat may help researchers better understand the human brain and how it functions.

Frank De Winne, my European crewmate, and I were the very first subjects for Neurospat. When Frank served as a subject, I would help him set up the hardware. When I was a subject, Frank would help me in return. The biggest challenge of hardware setup was to place the cap on our crewmate’s head without laughing. It’s impossible to keep a straight face when your crewmate is wearing a scalp-hugging red or blue polka dot cap with an electrical pony-tail and wires dangling around the face. We looked like jesters! 

In reality, this odd-looking cap is a sophisticated electroencephalographic, or EEG, measurement device that incorporates 64 electrodes within the fabric to monitor our brain waves. A few other electrodes hanging from the cap are applied elsewhere on our skin to monitor eye movements, muscle activity and cardiac rhythm.

An important task of the assistant was to apply just the right amount of electro-conductive gel beneath each electrode using a syringe. The gel reduces the electrical impedance between the electrode and the subject’s scalp, improving the signal quality.

The pony-tail of the cap connects to the Multi-Electrode EEG Mapping Module—say that three times quickly!—which is a unit within a payload rack in ESA’s Columbus laboratory. This unit not only collected the data from the 64 electrodes, it also transmitted it to the ground. At the end of each Neurospat session, there was a lot of data that needed to be transmitted!

The fun began once the hardware was ready, the cables were connected and the data was flowing. For the next 70 minutes Frank and I repetitively performed four different experiment tasks while free-floating.

A computer screen, which we viewed through a tunnel adapter, presented specific tasks to us. Two of these tasks assessed our perception of visual orientation. Using buttons on a keypad, we evaluated the orientations of lines and estimated the locations of dots on the face of an imaginary clock face. This portion of the experiment was tedious. Frank and I joked to ourselves that while Neurospat claims to be a cognitive function experiment, this portion of the experiment was secretly a sleep induction investigation!

The other two Neurospat tasks were visuomotor “docking” tasks that kept us attentive and wide awake. The objectives were to alternately pilot a simulated Soyuz-like vehicle to a docking port on the space station, or to manually dock a Progress-like vehicle as if we were a cosmonaut working from a control station inside the station. This was similar to a video game requiring the use of a joystick. As we worked to complete each docking task quickly and accurately, the EEG cap monitored the functions of our cerebral cortex. I loved this portion of the experiment, since the tasks appealed to my competitive instincts.

After the Neurospat equipment has been set up, the free-floating test subject performs 70 minutes of cognitive function tasks. (NASA)

Researchers are already analyzing the data from Frank, myself, and all of the other astronauts who have participated in Neurospat to date. They compare our performance in space to our performance on the ground, both before and after flight. The scientists are particularly interested in our brain wave patterns, since these provide insight into our neural and cognitive processes while we performed the tasks.

Scientists hypothesize that long-duration spaceflight affects an astronaut’s sensorimotor system and cognitive abilities. Specifically, they think astronauts may have difficulty determining which way is up, and that our cognitive processes in space may be degraded by stress, fatigue and disrupted sleep.

Neurospat data collection is scheduled to continue on the station through September 2012. The research team expects to have enough astronaut subjects by the end of this year to complete their analysis and publish their results. I enjoyed Neurospat, as it was an experiment that fully engaged me in the science and data collection, putting my training and skills to the test. For an astronaut who is interested in payload operations, it doesn’t get any better than that.

Inspiring a Generation

The International Space Station Program Science Office would like to dedicate this entry of A Lab Aloft to the life and work of astronaut Sally Ride, who passed away July 23, 2012. In today’s A Lab Aloft, guest blogger Cindy Evans remembers working alongside Sally and the inspirational legacy she leaves behind.

I was just thinking about Sally Ride last week, while my family and I were on vacation in Russia. One afternoon we decided to visit the spectacular Monument to the Conquerors of Space in Moscow. The impressive park that surrounds a soaring rocket features statues of some of the Russian spaceflight pioneers, such as Valentina Tereshkova, the first woman in space. Reflecting on Valentina’s face quickly led to a family discussion of American space pioneers, including the first U.S. woman in space: Sally Ride.

Of course, Sally is remembered for lots of things in addition to her first spaceflight mission. She was also a scientist and a champion of teachers, students and parents around the world because of her passion for education. It was this love of learning and the desire to share it with others that led to me getting to know Sally.

I met Sally in 1995 when she invited me to be part of her team to plan her space shuttle educational payload: KidSat. This was the pilot program for what would evolve into today’s EarthKAM, one of the most prolific education investigations on the International Space Station.

Sally’s concept for KidSat was simple: put an Earth-viewing camera on the space shuttle and let middle school kids take photos. Their target could be their own town, a place they are studying in history class, the Amazon rainforest, or the location of an event in the daily news. By letting kids control a camera from space, Sally knew they would be inspired as they learned.

Teachers used KidSat as a launching point to cover lessons on a wide variety of topics. They highlighted the basics of spaceflight, including gravity and orbits. Students applied KidSat to math and science, too. They learned the importance of precise calculations to make sure they could capture their targets. In viewing the final images, students covered Earth science and geography and honed their communications skills by describing their observations in writing. As a team-oriented task, KidSat reinforced the importance of working together to achieve greater successes.

When I was working with Sally in the mid-1990s, we were simply trying to see if KidSat could work. The first mission in 1996 was tested by teachers and students from only three middle schools: a rural school in Humbolt, Calif.; an inner-city school in San Diego, Calif.; and a magnet academy in Charleston, S.C. The small educational team included teachers from these schools and a few more.

Sally assembled a diverse team for KidSat, including education specialists from NASA’s education program, flight controllers from NASA’s Johnson Space Center mission operations, college students at the University of California, San Diego, database experts from NASA’s Jet Propulsion Lab, and a couple of interdisciplinary Earth scientists like myself to guide the science curriculum development with the small cadre of middle school teachers.

Every step of the way, Sally leaned on those teachers to make KidSat work. The teachers wrote the classroom activities and provided feedback on the spaceflight stuff (orbital dynamics for 6th graders—really?). They thought through the implications of conducting a mission in the classroom during the middle of the school year, which would include four days straight and midnight operations! The team also forecasted potential failure scenarios from a classroom perspective, such as: What if my dyslexic students transpose numbers? What if we can’t get Internet? What if it is cloudy?

This truly collaborative and interdisciplinary partnership that provided opportunities for KidSat continues today with space station’s EarthKAM. The inspiration and lessons spill over from science classes into other areas, such as art, math, English, and even gym!

Of course, both of Sally Ride’s Earth observation investigations were remarkably successful. KidSat grew during the first 3 flights of the program from 3 to 17 to 52 schools! Hundreds of schools have participated since that time, involving tens of thousands of students. Today, EarthKAM continues to inspire where KidSat left off. Pulling in thousands of participants with each operational opportunity, EarthKAM has reached more than 190,000 students to date.

My reflection about Sally leads to the core of what she inspired and championed—innovative learning for middle school kids, and a celebration of our natural curiosity about Earth and the Solar System. Through her legacy, she will continue to inspire for generations to come and I am honored to have been part of her team.

Experiencing the First Annual ISS Research and Development Conference

In today’s A Lab Aloft, guest blogger Emily White, with the Center for the Advancement of Science in Space, or CASIS, shares her experience at the First Annual International Space Station Research and Development Conference.

In late June, the Center for the Advancement of Science in Space, or CASIS, and the American Astronautical Society, or AAS, in cooperation with NASA, cosponsored the First Annual International Space Station Research and Development Conference in Denver, CO. The conference promoted future space science opportunities through keynote speakers and a variety of breakout sessions focused on space research, accomplishments to date and educating attendees on pathways to space station utilization.

The major theme of the June conference was the “Decade of Utilization.” On the first day of the conference, NASA Chief Scientist Waleed Abdalati commented that the “station empowers us to understand our world.” CASIS, as the nongovernment nonprofit organization that manages the space station’s U.S. National Laboratory, facilitates use of the National Lab for improving life on Earth. By collaborating with AAS and NASA on this conference—the only annual gathering that showcases the full breadth of research and development aboard the station—the CASIS team was able to share this goal with nearly 400 attendees representing scientists and organizations from a variety of fields, including many investigators new to space.

On day two, CASIS Interim Executive Director Jim Royston moderated a panel focusing on upcoming research opportunities on the station’s National Lab. Deepak Agrawal, our Director of Science and Technology, represented CASIS; Larry DeLucas, from the University of Alabama at Birmingham, discussed crystallization research; and Jeff Manber of NanoRacks discussed his company’s research platforms. These talks paralleled the current and near-term activities of CASIS. In fact, CASIS released our first Request for Proposals, or RFP, in the field of protein crystallography on the first day of the conference. An RFP in materials science, in collaboration with NanoRacks, will be released in the coming months.

As mentioned above, many new-to-space investigators attended the conference—an exciting success for the space science community that has long sought to attract new players to the space station. Those of us from CASIS were especially encouraged, since one of our major goals is to make space science accessible to a broader community. Toward this goal, the final day of the conference was aimed specifically at new users.

In the morning, CASIS Director of Operations Duane Ratliff moderated a workshop for new investigators on space station utilization. Expectations were that maybe only a handful of new researchers might attend the workshop, as it was the last day of the conference. Instead, the room was full of attendees, many of whom had never sent an experiment into space. An Implementation Partner Tradeshow complemented the workshop. Booths targeting potential investigators were set up by companies with expertise in developing and integrating payloads for flight to the space station.

Presentations and video footage of the First Annual International Space Station Research and Development Conference are available on the CASIS website and the AAS website.

It is an exciting time at CASIS following the conference and the release of our first RFP. Having been with CASIS since almost the start, I’ve watched the organization grow and bring on talented team members, and the RFP release is a major milestone and an energizing achievement for all of us. On the second day of the conference, CASIS also announced a signed Memorandum of Agreement with COBRA PUMA GOLFTM to conduct space-based materials research projects for use in its sporting goods product line. Along with this announcement, we released our design for a “Space Is In It” product endorsement that will be awarded by CASIS to select products enhanced by National Lab R&D. A very busy week!

The week prior to the Denver conference, CASIS team members attended the annual BIO conference in Boston, where we had a booth in the exhibit hall and productive and encouraging meetings with a variety of companies and foundations.

As the momentum builds from CASIS outreach events and announcements for research opportunities, we hope to attract even more pioneers in the R&D community and to support the efforts of the next generation of innovators.
