2014 Retrospective a Look Forward as the Space Station Comes into its Own

Posted on by .

In today’s A Lab Aloft International Space Station Chief Scientist Julie Robinson, Ph.D., looks back on 2014 to highlight some of the year’s milestones and research achievements.

As I take a moment to reflect on the accomplishments of the past 12 months, I can’t help but think of how they relate to where we’re going next with the International Space Station. From the crew capabilities to research goals, from NASA’s plans for continued exploration to the benefits for humanity from station studies, there are some key areas that stand out from 2014.

During the last year there has been so much demand for research on the space station—including investigations that require crew time—planners really have had to push the schedule. We deferred some preventative maintenance, scaling back on some filter changes, for instance, to adjust operations for increased crew time for research. That’s allowed us to get as much as 47 hours a week averaged in a six-month period. This number is the total for the three U.S. astronauts, rather than the original standard of 35 hours for science. When you think about it, that’s almost half again as much research as the designed schedule.

This is a great performance of balancing time aboard station, though we won’t always be able to hold to that. This is why we still need to go to seven crew members. The crew dedicating time to tend to investigations helps us to optimize the research coming out of space station, as well. Currently we house six crew members in orbit aboard the space station, and some of you may know that this is one person short of the craft’s design to sleep seven. This is because our Soyuz “lifeboat” can only return six crew members in an emergency. The advent of commercial crew will allow us to expand by that extra crew member, as the new vehicles can ferry four. This is a future goal that we all look forward to:  a full house.

The crew was particularly busy during the latter part of 2014 with a huge new capability for biological research using model animals. This also was driven by user demand to launch rodents—meaning mice and rats, though so far we’re starting with mice on the space station. We now have a system that can launch rodents aboard the SpaceX Dragon vehicle. The animals can live aboard station for a long period of time in special habitats, and then either be processed on orbit or eventually returned live. This system was important to get online this year, because we had a large number of users in medical research and pharmaceuticals interested in using space station as a test bed for their studies.

There are many discoveries that have affected human health that were dependent on the use of animals as what we call “model organisms,” from the discovery of insulin to the that of tamoxifen to treat breast cancer to kidney transplants. This doesn’t mean these organisms are going to grace the cover of a magazine, but rather that they provide a model for humans to help us understand disease processes. By watching how they respond to research, we can in turn learn how to fight those diseases.

Having the ability to fly mice to space for long-duration studies is a huge advance. Fulfilling this capability was our response to the Decadal Survey recommendations of the National Academy of Sciences. We have years of research already lined up hoping to get access to these mice. To optimize the potential for discovery, we combine as many experiments together on this precious resource as possible.

This is an exciting area of study, as just a handful of mice have flown in the past—both on space station assembly flights and one flight in a system called mice drawer system. Even so, those findings account for a significant number of our highest profile publications from space station research. With access twice per year, we now have this type of study as a routine capability. This means we can expect to see a huge ramp-up in high-impact research in biomedical areas.

Another big change this year has been the space station maturing as a platform for Earth science. My colleagues in Earth sciences at NASA have called this the year of the Earth, because they’ve had five related instruments go into space this year. That’s a record, and two of these are on the space station, a first!

Moving forward we’re going to see a couple instruments a year go up until the space station’s current external sites are primarily full, likely in 2017. We now need to study whether to grow our capabilities to support more Earth sciences instruments, as well as astrophysics and heliophysics studies.

It’s really thrilling to see these initial instruments come to station and begin operations right off the bat. The first of these, ISS-RapidScat, was bringing hurricane data home within three hours—this was less than a week after installation. The instrument measured the sea-surface winds and was used to look at Typhoon Vongfong in Japan. How quickly scientists can use these data and incorporate findings into use for us on the ground can provide real benefits. The results can give valuable information that people need to know to protect their lives and property, making it an important advance to have available aboard station.

Next is the Cloud-Aerosol Transport System (CATS), an imager that looks at clouds and aerosols for climate research. CATS will be followed by a number of instruments that are either brand new to science or that fill a gap from similar satellites to provide cross calibration. Our understanding of the Earth is going to improve thanks to the research from all of these instruments.

One of the areas that congress has encouraged us to pursue is the development of commercial applications and commercial research on the space station. To this end, they declared the space station U.S. segment a national laboratory in 2005. In 2011 we selected CASIS, the Center for Advancement of Science in Space, to manage that national lab side for use by researchers that are not funded by NASA. These scientists may be funded by other government agencies or the private sector or nonprofit organizations.

This year CASIS grew substantially with the advent of their ARK-1 and ARK-2 suites of investigations aboard station. Also in 2014, the first National Institutes of Health (NIH) investigator of the space station national lab era launched her immunology research study. There are other NIH studies to come, including one that looks at bone loss. CASIS also brought large initiatives in protein crystal growth, Earth sciences, stem cells and materials science to continue to advance commercial research aboard the space station.

I recently spoke with Brian Talbot, marketing and communications director with CASIS, and he shared his thoughts with me on the accomplishments of the organization for the past year. “The continued growth of CASIS as an organization in 2014 speaks to the limitless opportunities commercial and academic researchers see aboard the space station. Through funded solicitations in proven areas of space-based research to innovative and non-traditional commercial users, CASIS is moving ever closer towards its goal of fully utilizing of the national lab for Earth-benefit inquiry.”

When I talked about crew time, you may have noticed that it was broken down by U.S. and Russian segments and crew members. While this division is useful for tracking purposes, it’s important to mention how we are blurring those boundaries. This international laboratory brings collaborations together through research that transcend relations on the ground. The space station exemplifies a global partnership at its best.

One thing that has driven us to continue advancing our partnership is the announcement of the joint one-year expedition. Since the 2013 announcement, we have made advances in finalizing our research goals in preparation for the 2015 launch. This extended expedition will have an astronaut and a cosmonaut both stay aboard the space station for 12 months, instead of the current six-month standard. It’s been decades since astronauts were in space that long. With the leaps in our medical technology, the one-year stay will help us to better understand what happens to the human body on long-duration flights. These studies also may help answer related concerns for health here on Earth.

I’m really excited about how that international collaboration across all of our partners has evolved. We’re combining more investigations, we’re releasing open data for the entire global scientific community to work with and we’re joining crew member resources to optimize all of these activities. Whether it’s microbial sampling, taking care of plants or making specific observations of the human body, our crew members are working together on what is truly an international station in space.

Early this year, John Holdren, the director of the Office of Science and Technology Policy for the Obama administration, announced their support of extending the space station to 2024. We have worked through the impacts that this has for space station research and this extension gives us 90 percent more external research and close to 50 percent more pressurized research—those studies taking place in the cabin. 2024 is very important to what we can achieve with this global microgravity resource of the space station.

When we have scientists already in line wanting to do investigations, having more time to get those studies done and even to do follow-on research opens up the discovery potential. This also provides more time for research markets to develop independently. Just like on the ground, when someone wants to study a certain area, they contract a lab to do the experiments. Someday, when space station is gone, we want scientists to have continued access through this emerging market of microgravity research in space. This longer duration for station to remain as a platform helps to open up those opportunities for researchers around the world. This is the world’s chance to continue the mission of discovery off the Earth for the Earth.

Women in Space Part One, Female Firsts in Flight for Space Exploration and Research

Posted on by .

In today’s A Lab Aloft, guest blogger Liz Warren, Ph.D., recalls the inspirational contributions and strides made by women in space exploration and International Space Station research.

This month we celebrate the anniversaries of three “firsts” for female space explorers. On June 16, 1963, Valentina Tereshkova of the Soviet Union became the first woman in space. Then on June 18, 1983, Sally Ride became America’s first woman in space, followed by Liu Yang as China’s first woman in space on June 16, 2012. Though their flight anniversaries are not in June, I would be remiss if I did not mention the first European woman in space: Helen Sharman in 1991; the first Canadian woman: Roberta Bondar in 1992; and the first Japanese woman: Chiaki Mukai in 1994.

Each of these milestones built upon each other by inspiring the next wave of female explorers, continuing through today with the women of the International Space Station and beyond. With this in mind, I’d like to take a moment to celebrate women in space and highlight those with a connection to space station research. It is amazing to me to see just how connected these seemingly separate events can be. The steps of the intrepid explorers who engage in space exploration set the course for future pioneers, blazing the trail and providing the inspiration for those who follow.

To date, 57 women including cosmonauts, astronauts, payload specialists and foreign nationals have flown in space. Our current woman in orbit is NASA astronaut Karen Nyberg, working aboard the space station as a flight engineer for Expeditions 36 and 37. While Nyberg lives on the orbiting laboratory for the next six months, she will perform experiments in disciplines that range from technology development, physical sciences, human research, biology and biotechnology to Earth observations. She also will engage students through educational activities in addition to routine vehicle tasks and preparing her crewmates for extravehicular activities, or spacewalks.

Many of the women who have flown before Nyberg include scientists who continued their microgravity work, even after they hung up their flight suits. In fact, some of them are investigators for research and technology experiments recently performed on the space station. Whether inspired by their own time in orbit or by the space environment, these women are microgravity research pioneers ultimately looking to improve the lives of those here on Earth.

Chiaki Mukai, M.D., Ph.D. of the Japanese Aerospace Exploration Agency, for instance, served aboard space shuttle missions STS-65 and STS-95. She now is an investigator for the space station investigations Biological Rhythms and Biological Rhythms 48, which look at human cardiovascular health. She also is the primary investigator for Hair, a study that looks at human gene expression and metabolism based on the human hair follicle during exposure to the space station environment. MycoMyco 2Myco 3, other investigations run by Mukai, look at the risk of microorganisms via inhalation and adhesion to the skin to see which fungi act as allergens aboard the space station. Finally, Synergy is an upcoming study Mukai is leading that will look at the re-adaptation of walking after spaceflight.

Peggy Whitson, Ph.D. served aboard the space shuttle and space station for STS-111Expedition 5STS-113, and Expedition 16. She also is the principal investigator for the Renal Stoneinvestigation, which examined a countermeasure for kidney stones. Results from this science have direct application possibilities by helping scientists understand kidney stone formation on Earth. Whitson, who blogged with A Lab Aloft on the importance of the human element to microgravity studies, also served as the chief of the NASA Astronaut Office at the agency’s Johnson Space Center in Houston from 2009 to 2012.

Sally Ride, Ph.D. (STS-7STS-41G) initiated the education payload Sally Ride EarthKAM, which was renamed in her honor after her passing last year. This camera system allows thousands of students to photograph Earth from orbit for study. They use the Internet to control the digital camera mounted aboard the space station to select, capture and review Earth’s coastlines, mountain ranges and other geographic areas of interest.

Millie Hughes-Fulford, Ph.D. (STS-40) has been an investigator on several spaceflight studies, including Leukin-2 and the T-Cell Activation in Aging study, which is planned to fly aboard the space station during Expeditions 37 and 38. This research looks at how the human immune system responds to microgravity, taking advantage of the fact that astronauts experience suppression of their immune response during spaceflight to pinpoint the trigger for reactivation. This could lead to ways to “turn on” the body’s natural defenses for those suffering from immunosuppression on Earth.

Hughes-Fulford has been a mentor to me since I was in high school. It was Hughes-Fulford who encouraged me to pursue a career in life sciences, and she also invited me to attend her launch aboard space shuttle Columbia on STS-40, the first shuttle mission dedicated to space life sciences. In fact, STS-40 also was the first spaceflight mission with three women aboard: Hughes-Fulford; Tammy Jernigan, Ph.D.; and Rhea Seddon, M.D.

I followed Hughes-Fulford’s advice, and, years later, I found myself watching STS-84 roar into orbit carrying the life sciences investigation that I had worked on as a student at the University of California, Davis. In the pilot’s seat of shuttle Atlantis that morning was Eileen Collins, the first woman to pilot and command the space shuttle. Our investigation, Effects of Gravity on Insect Circadian Rhythmicity, was transferred to the Russian space station Mir, where the sleep/wake cycle of insects was studied to understand the influence of spaceflight on the internal body clock.

Women at NASA always have and continue to play key roles in space exploration. Today we have female flight controllers, flight directors, spacecraft commanders, engineers, doctors and scientists. In leadership positions, Lori Garver is at the helm as NASA’s deputy administrator, veteran astronaut Ellen Ochoa is director of Johnson; and Lesa Roe is director of NASA’s Langley Research Center in Hampton, Va.

In space exploration and in science, we stand on the shoulders of those who came before us. These women pushed the boundaries and continue to expand the limits of our knowledge. What an incredible heritage for the girls of today who will become the scientists, engineers, leaders and explorers of tomorrow.

Touching Lives via International Space Station Benefits

Posted on by .

We are proud to announce the new International Space Station Benefits for Humanity website. Today’s entry highlights how this international collaborative effort communicates positive impacts to life here on Earth from space station research and technology.

Last month at the International Space Station Heads of Agencies meeting in Quebec, Canada, my international counterparts and I had the opportunity to share the results of more than a year’s worth of work across the international partnership. This collaboration culminated in the launch of the International Space Station Benefits for Humanity website, which looks at the early results from the space station and highlights those that have returned major benefits to humanity.

This website was translated into all the major partner languages and there also is a downloadable book format. The 28 stories found on the site focus on human health, education, and Earth observation and remote sensing, but these are just some of the benefit areas. Others, such as the knowledge gained for exploration or basic scientific discovery, are found on the space station results and news websites.

It can be a bit challenging at first see which station efforts will generate direct Earth benefits. This is because when we do the research, we finish things on orbit and then it can take two to five years for the results to publish, and possibly another five years after that before the knowledge yields concrete returns. I think each of us, while developing these stories, found things that surprised us. I suspect readers will, too. Some of these developments and findings are so amazing they go straight to your heart!

For example, the Canadian Space Agency robotic technology developed for the Canadarm was really cutting edge; now it has been applied to a robotic arm that can assist with surgery. Brain surgeons have used this robotic arm to help some patients who were not eligible for a standard operation, because the surgeries were too delicate for human hands. With the robotic assist, still in the testing phase, they were able to save the lives of several patients. This is a remarkable development.

Another area where space technology returns offer a benefit to humanity is in the ability to provide clean water in remote regions and disaster areas. We also have stories about the ability to use station related telemedicine to improve the success and survival for women and their babies, if they anticipate complications during delivery. Providing a remote diagnosis to women in hard-to-reach areas enables them to seek life-saving medical care. These are just a few of the remarkable returns from space technologies.

The website also includes stories that focus on the research knowledge obtained during station investigations. One particular area gaining attention is vaccine development. Scientists are now creating candidate vaccines for salmonella that fight food poisoning, as well as one in the works for MRSA—an antibiotic resistant bacteria that is very dangerous in hospitals.

We also see ongoing benefits in the area of Earth observation, which our Japanese colleagues compellingly described after the Fukushima earthquake in Japan. The Japanese people were responding to that event in such courageous ways. Having information about what was going on really helped and the global community mobilized all the possible Earth remote sensing resources to provide aid via imagery of the disaster. The station provided imagery and data of the flooding from the original tsunami surge. I would like to share with you the comments of my JAXA colleague, Shigeki Kamigaichi, who was on the ground after the disaster:

“The Earth observation by astronauts from the International Space Station brought us several impressive image data offerings. Furthermore, the crew comments concerning the tsunami damage from March 11, 2011, to the people who suffered gave us a feeling of oneness and relief.”

One of the exciting things about Earth observations work is that the station passes over populated parts of the world multiple times a day. Our Russian colleagues shared some examples of work they had done to track pollution in the Caspian Sea using data from the space station. They also used Uragan imagery to understand a major avalanche in the Russian Caucasus region, determining glacial melting as the root cause of the avalanche. These imaging efforts really help as we look at ways to better respond and predict disasters and prevent future loss of life.

Of course, there also are the compelling educational benefits from the space station. It is inspiring to see students get excited about science, technology, engineering and math, simply by connecting them to space exploration. Education is a bonus, since this is not why you build a laboratory like this. Once you have that laboratory, however, you can make a huge impact in children’s futures.

One of the most widely influential examples of educational benefits are when we hear students from all over the world, not just station partners, using HAM radio contacts to speak with astronauts aboard station. This happens on the astronauts’ free time, when they can just pick up the ham radio and contact hundreds of students through amateur radio networks. These children ask questions and learn about everything from space to life aboard the station to how to dream big. It is a recreational activity for the astronauts, taking just a few minutes, but the students are touched for a lifetime.

Because this effort is so readily routed internationally, students in developing countries can benefit just as easily as students in other areas. In fact, 63 countries already have participated with the space station; a much larger number than the 15 partner countries. Education activities are a core international benefit.

While this initial launch of the Benefits for Humanity website was a big release, it is something we plan to maintain and continue over time with our partners. The work for these derivatives of station activities will continue to roll out over time, but we anticipate it to grow. When you have hundreds of experiments active during any six-month period on orbit, the throughput and the amount of crew time going to research each week is unprecedented!

The experiments are being completed faster than ever before and we are going to see these benefits and results coming out much more quickly, so it is an exciting time. It is important to start talking about these developments as we turn the corner from assembly to the full mission of research aboard this one-of-a-kind orbiting laboratory.

When will we know if research on the ISS has paid off?

Posted on by .

I often have the opportunity to do interviews with reporters who are interested in the kind of research happening on the International Space Station. Sometimes they are veteran space reporters, other times they are new and just learning about space research for the first time.

 

Regardless of their past experience, they often ask me for evidence that research on the space station is worth the cost. It is a simple question, but a misleading one. This is because it counts every penny on the cost side, but fails to account for the multiple benefits in addition to research results: international cooperation, engineering accomplishments, and research accomplishments.

 

The space station already benefits the country and the world through its construction and operation—even if it were never used as a laboratory, this would still hold true. We should not lose track of the power of daily international cooperation in constructing, operating and using the space station. The fact that this cooperation is on the cutting edge of space technology and for peaceful purposes amazes the previous generation, but is business as usual for us today. I work closely with colleagues at the main partner agencies, including Russia, the European Space Agency, Japan, and Canada; over 59 countries have participated in space station research or education activities through 2010.

The value of the space station as an engineering accomplishment should also not be underestimated. Common standards allow parts manufactured all over the world to interchange and connect flawlessly the first time they meet in orbit. Year round operations, 24 hours a day, 7 days a week, have now extended for 11 years, and we have more than a decade ahead of us. The various life support technologies developed for station provide redundant capabilities to ensure the safety of the crew. They also provide technology advances that benefit people right here on Earth—for example, new compact technologies provided water purification after earthquakes in Pakistan and Haiti.

disaster in 2005. The unit is based on space station technology and processes

Even if we could place a monetary value on peaceful international cooperation and engineering advances from building and operating spacecraft, finding the true long-term payoffs of scientific research is very challenging. Some items could be tabulated as direct benefits from space station research—things such as new materials and products that can have a measurable market impact. Beyond the obvious items, however, the calculations get fuzzy. New products can lead to long-term economic value by making safer vehicles, by extending human life, and even by advancing the quality of life. What might appear as esoteric knowledge may indeed be the first critical steps on the path to a high-value breakthrough. Let us not forget indirect benefits from educational activities, job creation, and economic growth, as well. Colin Macilwain wrote a great critical review of the general challenges of valuing the worth of science in Nature last June, Science Economics: What Science is Really Worth, which I recommend for those interested in the challenge of valuing science.

 

In the coming weeks I will share with you stories of some of the direct benefits that I see coming from space station research. These developed from the modest research throughput during the station assembly period, prior to the full use of the finished laboratory we have today. Based on publications so far, most space station experiments take 2-5 years post-laboratory to publish results. New products related to these results take another 5-10 years or more to transition to a direct benefit. In fact, the space station will be deorbited before an accounting can be completed.

 

Along this journey, there are some really exciting possibilities emerging. I invite you to browse developments from space station research via our key results Web site, as we monitor the progress from knowledge to direct benefits.
