What’s Coming Up on the EPO End

By Dana Lis – Education and Public Outreach coordinator

Just down the canyon and a little to the side, from Pavilion Lake to Kelly Lake – Welcome! Another year has flown by and I find myself heading east again to see some of the crew that I have had the pleasure to kick out of the kitchen over the past 5 years, and meet some new friends as well. This year I do not have a blue Volkswagon Vanagon or orange Westfalia jammed to the roof with food for the team. I am somewhat pleased with not having to drag a weighed down VW on a long road trip and am impressed with the minimal equipment necessary for my new position as the EPO coordinator. In less than 24 hours, simply myself and my mac-apple-mac laptop (and road bike of course) will step off the plane and into the 2011 field season.

When Darlene Lim offered me the EPO position my first instinct was “ I do sport nutrition, not twitter – no thanks.” Always up for the learning opportunities of a new challenge I accepted the position and have been mostly thrilled ever since.  Now I can’t wait to continue to share the amazing science and exploration activities of 2011 with you. This field season will be full of great discoveries, and will highlight some of the best space science and exploration activities that happen on Earth!

Not only have we expanded to a new location and new community, but we welcome some talented new folks: The JSC Timeliners/Robotics group, Liza Coe from NASA-Ames and Sean Maday from Google.Check their bio’s out here. Jessica Parsons from NASA HQs, Raffy Pendery from Studio 98 and I will be working hard to keep you updated from the field – with blogs like this one, tweets, facebook posts, photos, and videos from the team’s daily science and exploration activities. We welcome questions about our research through any of these channels, and will endeavor to answer questions from you as soon as we can! You can also submit questions to Henry Bortman through Astrobiology Magazine.

Stay tuned for some great media coverage by BC Magazine, Discovery’s Daily Planet Series, New York Times, Earth Periodical and much more. Thanks for your interest in our project, and welcome back to the Pavilion Lake Research Project at Kelly Lake.

Once I land in field camp I will update on the DeepWorker arrival, barge set up and the first DW flight of 2011. Keep checking in.

Sub Operations day 1

By Allison Bradi – PLPR science lead from University of Calgary

I’m sure many of you have heard the old adage ‘if it ain’t broke, don’t fix it’. Well, sometimes you learn the most when you take something apart and have to put it back together again. We knew that moving to Kelly Lake from Pavilion would provide some challenges and yesterday as our first day of DeepWorker flight operations, we certainly faced a few hiccups. The navigation software had a few bugs and wasn’t talking to the subs. This was problematic as it meant that although we’d still be able to get video from the subs, we wouldn’t be able to track them as they moved around the lake. One of our main goals at Kelly is to map the distribution and morphological variation of the microbialites at the lake and without the ability to track the subs, we wouldn’t be able to identify the location of images that are collected in order to build our map. But, the scientist pilots themselves are also a valuable source of observational information that should not be overlooked and so we decided to go ahead with the flight of at least one of the subs so that we could gather some input about the microbialites and proceed with our science. With that decision made, Sub 7 was away and happily exploring the eastern shore of Kelly Lake. The flight started off under cloudy weather but soon the sun cleared and it must have brought some good luck with it as the navigation software also starting working shortly thereafter and we were able to get tracking for the majority of the flight path. In the end, we didn’t complete our DeepWorker missions quite as planned and Sub 6 was unfortunately not launched. Sometimes science doesn’t go as planned and you need to roll with the punches, we learned a lot and Day 2 of the DeepWorker operations is expected to benefit from these lessons learned and is expected to go a lot smoother. Stay tuned!

Monitoring operations from the Mobile Mission Control Center (MMCC)

The science backroom team operations

By Jennifer Biddle PhD- Researcher at University of Delaware

I’m so excited to be officially joining the PLRP team this year as part of the science team. I got excited about astrobiology in graduate school and after my PhD, was a NASA Astrobiology Institute postdoctoral fellow. When I became a professor, I kept looking for ways to stay involved in NASA and astrobiology science. I collaborate with the NASA Astrobiology Institute at Penn State University and now am part of the PLRP team!

I typically do deep sea research, so the PLRP approach of using manned submarines is not too unusual to me. What is unusual is that we’re taking an analog mission approach to the science and exploration – complete with a mobile mission command center. I’ve been really impressed with the amount of infrastructure that the team has had to create in order to do their work, including setting up wifi in remote places and running video feeds across miles. Typically my research done on a ship has communications already on it – we just hop on and do science. Coming to a remote (and beautiful!) site in British Columbia certainly presents challenges.

Today I got my full immersion into PLRP science and headed up the science backroom team for the third dive in Kelly Lake. One disadvantage of a single manned sub is that only one person is seeing and observing things in real time. Maybe they can take a video, but the rest of us might wait hours to see it. That means decisions are slowed and science might be impeded. So this year the team designed a way to have a sub tethered to a cable, sending video feeds to the surface – and then the coms team has been able to shoot video back to the mobile mission command center. What this means is that many of us scientists can sit in comfort and see and hear what the pilot of the sub is observing. That way we can confer on what we are seeing immediately, add extra sets of eyes to a busy pilot and give advice or opinions on what is happening. Really what we did was sit back and go “Cool!” when a lovely microbialite would pop up on the screen.

We additionally got a true mission-feel when we started doing delayed communications. If an astronaut is off of the Earth, it takes a while to talk to them! So even though our sub pilot was only a few kilometers away, we gave ourselves a delay to see how things would go. Not surprisingly, it did seem easier – doesn’t your job go better when your “boss” stops interrupting you? But we’ll see how well it works when we actually want samples. Maybe 10 brains are better than one – maybe not! It’s part of this week’s experiments. My final experiments won’t be done for a while. We are collecting samples from Pavilion and Kelly Lakes to continue to describe the microbial communities that are in the microbialites. My group is specifically interested in the phototrophic (light-harvesting) communities, who we expect are driving the distinct shapes we see in these structures. Our work is in progress, so now updates yet – but watch for later updates as we start to unravel the mysteries of these beautiful and mysterious microbialites!

Pavillion Lake, Microbialites, DNA and British Columbia

by Joe Russell – PhD student from University of Delaware studying Microbiology

Most days I do science in a bright, cluttered (yet clean), indoor laboratory. Right now, I am sitting on the shore of a pristine lake in British Columbia, waiting for samples of microbialites. Long days and late nights in lab is what you pay the piper for sample collections in beautiful, remote locations.

What I knew of British Columbia was what I saw during the Vancouver Olympics and a handful of nature shows. It was beautiful, with tall mountains, good skiing, and killer whales. What I didn’t know was how diverse and rugged the landscape would be. I flew into Vancouver and drove a rental car up to our field site along with my advisor, Dr. Jen Biddle. We passed through the city into tall snow-capped peaks covered in conifers. Beautiful, but about what I expected for BC. My expectations were quickly dashed. Lush forests spit waterfalls down into the Fraser River. Within an hour or two, the conifers gave way to more rock outcroppings, and eventually huge, sheer cliffs with rocks of all different colors. The vegetation changed to more bristly, desert flora. Winding streams worked their way through distant pastures, dotted with gnarled trees, horses, and cows; eventually all spilling into the Fraser, a constant throughout our drive. As we approached the town of Clinton, our base of operations for this expedition, the conifers returned, although this time in different arrangements. The dense coastal firs, spruces, and hemlocks gave way to more sparse cedars and ponderosa pine forests that populated steep, rocky canyons. Tucked away deep in the folds of these ancient canyons are two very unique and exciting lakes.

Pavilion Lake and Kelly Lake are home to a fantastic display of microbialites. A fun, quirky, inspired (from what I’m beginning to see) group of scientists with a variety of backgrounds have descended on these lakes to study these structures because they may hold answers to some of the most profound questions we can ask. What did some of the earliest life on this planet look like? How did it survive and evolve? The fossil records show that for a couple billion years of our planets history, life existed similarly to how it does on the microbialites of Pavilion and Kelly Lake. If these structures were such an important first step in Earth’s life history, might they also be something to look for when we eventually explore other planetary bodies in our solar system and beyond? As a microbiologist, with a strong interest in astrobiology, these questions floor me. To be here in this beautiful countryside searching for answers is what some refer to as “pinch me” moments.

My role here is to help understand the bacterial communities that live on the surface of the microbialites, and from what we can tell, drive their formation. I have spent the past few days taking part in planning and execution of submersible dives and sample collection. Once samples arrive at base camp, I extensively document what I see. Interesting features such as curious green and purple nodules that may be the site of carbonate formation on the surface of the microbialites are sub-sampled and examined under the microscope. Larger chunks of microbialite are carefully bagged and frozen for shipment back to the lab at the University of Delaware. There, I will extract DNA to study the microbial population of these structures on the genomic level to determine which members of this population are most important at different depths. This study highlights one of the unique attributes of Kelly Lake and Pavilion Lake. Microbialites are found in a handful of places around the globe yet these lakes are the only environment where they are found at such a variety of depths (thus differential access to light). It is our hope that these varying growth environments within the lake will be able to highlight distinct attributes of microbialites that made them so successful on early Earth and could possibly aid their formation on other planetary bodies.

NEEMO 15 Engineering Tests: Education and Public Outreach

While everyone gets an idea of all of the exciting engineering tests and evaluations going on this week in Key Largo, Fla. for the upcoming NEEMO 15 mission from these daily blogs, not many folks know about what goes on behind the scenes to inform YOU about what’s happening with the day-to-day activities. What it takes to get the word out, what it takes to let you in on the cool tests and evaluations that these hardworking engineers perform undersea and on the ocean floor at the Aquarius habitat, and what it takes to bring the action to you, so you can enjoy it, interact with it, learn from it, and be inspired by it.

One method would be a blog, just like this. Another, perhaps a press release or media advisory or interviews with media outlet, or maybe one of those new fancy social media outlets. Who updates those and answers all of the questions? What about all of those cool photos… who takes them, who organizes them, how are they stored? And let’s not forget about those really awesome live interactive education events! How in the world do you coordinate getting into a classroom full of kids in a remote location, tying in an education specialist at Johnson Space Center, adding a live video feed from a boat out at the Aquarius, talking live with a person at the Aquarius Reef Base Watch Desk, and interactively chatting online at the website where the live video feeds?

How we inform the media or public, how we bring live education events to classrooms, how we document and record the mission, takes more than one person and more than one asset. It takes a team of people located in different centers and some on-site, to know all the technical details of the mission and to be able to follow what is happen throughout the day to entertain, interact with, inspire you.

So, here is an snapshot of our Education and Public Outreach activities that happen on a typical day during our NEEMO mission during our engineering evaluations. We start our day bright and early, with our all-hands meeting with the NEEMO mission manager. From there, we get ready for the rest of outreach activities throughout the day. For example, set up a phone interview with a national media outlet, conduct recorded interviews with subject matter experts for use during live events or in the case of a communication issue during a live event, write a basic script and coordinate and test the communication equipment and phone lines for interactive education event that will occur the following day, continually update Facebook and answer questions, tweet throughout the day and respond to questions on Twitter, meet with the engineering team when they get back from their day activities, download all of the photos and videos taken throughout the day to a server, sort through and pick favorites to upload to Flickr and write captions for those. Coordinate a photo shoot at mission control. Write a blog, such as this! Set up for a live distance learning (DLN) event and execute it.. Pretty crazy, huh?! And then, the day ends by documenting all of the work, lessons learned, preparing for the next day, and it all starts all over again the next day.

NEEMO 15 Engineering Tests, Day 2: Taking Designs Into the Field

NEEMO 15 engineer divers

Engineer divers get ready to install the translation tool simulator into the wall.

The NEEMO-15 mission will be in October, and in an engineer’s mind, that means there’s still time to iterate on designs. Today the engineering team took some of those designs into the field. One of the devices tested today was a “spacesuit waist ring simulator.” It acts as the waist structure of a spacesuit would, except it’s attached to a diver wearing SCUBA tanks. It holds EVA tools, provides stability against structure, and even blocks some of the view, just as a spacesuit’s waist ring would. So today, after constructing this device in labs and workshops, it was finally time to put it in the water. After estimating it’s weight and buoyancy (and yes, there were bets on whether it would float!), it finally had its first taste of the ocean while still dockside. It checked out, as did the other tools and giant fiberglass “rockwall” that some of the experiments would mount to. So after the paperwork was all signed off, the team set out to the reef.

When arriving at the site – on the same reef but some distance away from Aquarius – the team lowered the rockwall to the ocean floor. Then, one-by-one, test subjects, utility divers, and support divers worked through their checklists and started the clocks on their dive. Astronaut Mike Gernhardt, the test subject actually in the “rig,” found the buoyancy to be near perfect (something that can sometimes take 30 minutes to correct), and started the experiments right away. The first thing that struck everyone was the visibility – the bright sunny, calm day helped the lighting – but the silt being kicked up made it impossible to see further than 10 feet. For the most part this didn’t affect the experiments, and the team pressed ahead. They tested hand-over-hand translation with anchor points on the rockwall, foot-restraint ingresses, anchoring in the silt to stabilize the setup, and using a rigid standoff attached to the waist ring for body stabilization. All while their time was ticking away – and they were not able to speak to each other. This was shaping up to be quite the debrief session.

Anchor tool

This tool will be an anchor and the aquanauts (or divers, in this case) will use the different lines to translate in the surface of an asteroid.

Once back on the boat, the crew discussed what they had learned. Either luck or excellent prediction had caused the rig to be perfectly buoyant, but some stabilization was needed on the waist ring – and the fins – they proved to be positively buoyant by sending the subject’s feet sinking after they were removed. Mike was happy to share an interesting discovery: while holding an excursion line anchored in two locations on the “asteroid,” one could effectively pull against the surface and walk, just as if there was gravity! There were other lessons learned, and many adjustments that would need to be made overnight and in the next few days, so the team used the trip back to base to rest and, well, talk more about the big picture.

I guess you could call it an engineering brainstorming session. Not one with whiteboards, flowcharts and venn diagrams, but just bunch of people, passionate about space exploration, talking on a boat. They all had huge variations in their backgrounds and individual training, and just witnessed a sampling of how difficult it would be to possibly someday explore an asteroid. Were the issues they saw today the same ones would be face on an asteroid? No, but some of them were strikingly analogous: The near-zero visibility had a similar effect to what could happen after touching the surface of a dusty asteroid. Body movements made on the ocean floor while “almost” neutrally buoyant are similar to what astronauts would face when moving across the surface of an uncharted asteroid. And how will we know what anchoring techniques would be effective? As the team neared the base on the shores of Key Largo, their conversation shifted to the varieties of anchoring tools we use here on Earth. Not knowing what kind of surfaces are out there is making us consider a variety of approaches from many “analogous” situations here on Earth: rock climbing, foundation repair, even drift diving.

This was just a snapshot of one day of experiments in preparation for the NEEMO-15. The countless hours that go into getting ready for a mission are one of the many similarities to NASA’s space missions. Significant is the fact that NEEMO-15 will mimic something that has never been done by humans before. The question could be posed: Isn’t this just a combination of what we have done in the past? Combine the weightlessness, tethering and translation techniques on the International Space Station, and then add to that all of the knowledge gained putting human feet on another world during the Apollo program. Right?

Not quite. The final discussions of the evening (after hours of replanning, retooling and regrouping) were about how asteroid exploration is definitely the most challenging of both worlds. Exploring a possibly dusty, wholly unknown, completely uncertified, essentially weightless, “surface” of an asteroid, would definitely be more challenging than combining the sum of our lessons learned from the Moon and ISS. Those experiences under our belt will be the basis of much that NASA does in the future – but we all agree it’s a good thing we’re learning how to hone our skills, here on Earth.

Today was a busy day in Key Largo, Florida for the support crew of the NEEMO 15 engineering tests. Personnel of NOAA’s Undersea Research Center, or NURC, were busy activating the Aquarius and preparing for this week’s intense diving operations. They left the dock here at the shoreside support facility, aptly named Aquarius Reef Base (ARB), early this morning and were out conducting operations at the Aquarius site, approximately 5 miles south-southeast of Key Largo.

They started up the generators and compressors on the Life Support Buoy (LSB) directly above Aquarius. The LSB has an umbilical directly down to Aquarius to supply it with fresh air, electricity, and communication links. Divers then descended to Aquarius and powered up all the systems and tested the communications equipment in preparation for the week’s upcoming events. NEEMO mission specific tasks were also performed, such as setting up portions of the rock wall, and testing the remotely operated vehicle (ROV).

While all this was going on offshore, the NASA support team was busy onshore at ARB assembling structures to be placed on the seafloor such as mock-ups for the Multi-mission Space Exploration Vehicle (MMSEV) and suit port alignment guides (SPAG), anchoring and tethering devices, translation hardware, and telescoping booms with foot restraint devices. Additionally, they conducted familiarization training on the diving equipment, and checked out equipment to be used on the week’s intense dive operations, to begin tomorrow. Safety briefings were given by the NURC personnel and swim tests were conducted on those dive team members who were either new to the project, or no longer current by NURC’s guidelines. Several runs to the local dive shops and hardware stores were needed to make up for any shortcomings in the original logistics.

(NASA Virtual News) – We’re in the Second Life rover yard this morning, preparing for a D-RATS mixed reality event from the Arizona Black Rock volcanic field. We’ll stream the live, real-world webcast into Second Life’s social media 3-D world to create an immersive, participatory experience for the Second Life community.

The rover yard in Second Life replicates NASA rover activities so users can share in NASA’s compelling story of science and exploration. Mission concepts and technology models are available to everyone in this hands-on, distance-learning environment. Second Life residents are telepresent as they work together and communicate about the design, analysis and performance of space technology and events. This feeling of telepresence creates a collaborative bond that fosters engagement, conversation, feedback and learning.

The NASA eEd island is a venue to investigate education outreach and ultimately the usefulness of conducting science in virtual world platforms. As virtual worlds evolve it’s possible that shared virtual spaces such as Second Life will include the planning, development and training for future D-RATS missions. Scientists and engineers will routinely use desktop 3-D technology to spatially investigate large data sets, explore human factors issues and perform simulated tasks.

Back from the future of virtual worlds to here and now, where Second Life residents are dropping in to participate in the Arizona D-RATS webcast with NASA scientists. During and after the webcast, the conversation spins from what the rovers will be used for, their destinations, the size of the rovers and vehicles to get them to their destinations. The group is a mix of scientists and educators interested in NASA’s work.

Desert RATS: What now?

By Dr. Jacob Bleacher
Dr. Jacob Bleacher is a Planetary Geologist working at NASA Goddard Space Flight Center. For the 2010 Desert RATS field test, Dr. Bleacher was the geology crew member on rover B during week one.

Now that the field test is over, what will our team be doing? Some of you might have heard that one goal of this field test was to experiment with several different operational modes. Two different exploration strategies that we examined included different approaches to using two rovers at the same time, and two different communications capabilities. The two approaches to using both rovers were called “Lead and Trail” and “Divide and Conquer.”

During “Lead and Trail” operations, both rovers and crew operated in close proximity to each other, often exploring similar geologic terrains. In general, the rovers maintained line of sight, but most important was maintaining communications during these operations. If line of sight and communications were lost for a period of time, both rovers were required to return to the last location in which they had communication with the other rover. In general, this resulted in the rovers being no farther apart than 1-2 km.

During “Divide and Conquer” operations, both rovers were free to explore different geologic terrains without maintaining line of sight or as strict communications. This enabled both crews to cover more ground as a team, but should something go wrong, they would be farther apart from each other and less able to help each other out of trouble.

The two communications scenarios that we tested were called “Two-a-day Comms.” and “Continuous Comms.” Together, these two scenarios represent the opposite extremes of how we might set up our communications capabilities for future missions.

During “Two-a-day Comms,” the crew were not in communication with the science backroom or Mission Control during the day. Crew were responsible for making sure that they arrived to predetermined sites, at which our communications hardware would enable us to touch base with the backrooms. As we slept in the rover overnight, the backrooms would work to download all of the data that we had collected the day before. At the beginning and end of each day, while we were still in communication with the backrooms, we would have meetings to discuss what we had seen during the day, and what the plan was for the new day.

During “Continuous Comms,” the crew were able to communicate directly with both Mission Control and the science team at all times. This enabled the science team to keep track of what we had done all day, and took some pressure off of them while working through the night to interpret all of our data.

As you might suspect, each scenario resulted in slightly different outcomes. As we have read already, the Human Factors team was tasked with keeping track of how the crew physically responded to the work environment, which is strongly influenced by these different scenarios. Meanwhile, the Science Team was keeping close track of which combination of scenarios provided the greatest science value.

Now that the test is over, it’s time for the team to evaluate what the outcome was of these different scenarios. Each scenario will also need to be balanced against the cost it takes to make it happen. So, which one was best? What do you think? Stay tuned. You might very well see the answer to that question in the way that our future missions are designed to send humans to the moon and other planets. And you can say you saw it all unfolding when you kept track of the Desert RATS and other NASA Analog Field Tests.

Desert RATS: Space Exploration Vehicle Versus Lunar Rover

By Dr. Jacob Bleacher
Dr. Jacob Bleacher is a Planetary Geologist working at NASA Goddard Space Flight Center. For the 2010 Desert RATS field test, Dr. Bleacher was the geology crew member on rover B during week one.

One of the great advantages of the Space Exploration Vehicle (SEV) is the ability for the crew to return to a “shirt sleeve” environment (like your living room) inside the rover, to relax between Extra-Vehicular Activities (EVAs). In an earlier blog, Dr. Rice mentioned that the Apollo J-Missions (15-17) brought along a rover. This rover enabled their crew to cover much more ground than the earlier Apollo missions and was a great advance for human exploration of another solar system surface. However, the Apollo rover was unpressurized, meaning the crew needed to be in their spacesuits for the entire time, as they roved the lunar surface.

During the J-Missions, crew members were in their pressurized suits for up to 8 hours a day for 3 days of exploration. Operating in a pressurized suit is difficult and can be painful. It is manageable for a short period of time. Future missions to explore the solar system with humans may be longer duration missions, such as 7, 14, 30 days or even longer. If crew members were to use an unpressurized rover for missions of this length, they would be forced to wear their pressurized suits for much longer periods of time than their Apollo forefathers.

As I mentioned before, the suitports help us to keep dust out of the rover. They also give the crew a break between EVAs so they do not feel as much discomfort or exhaustion as a result of wearing pressurized suits all day, every day, during a mission. As Dr. Robert Howard reported in his blog, the human factors team is monitoring how tired we become during EVAs and how quickly we can recover while resting inside the rover. During my week in rover Bravo, we went on one EVA for almost 3 hours, as did the crew of Rover Alpha. In the second week, one crew went on two EVAs in one day that were just as long.

I can say, that at the end of my long EVA, I was very happy to return to the rover. After using the suitport to enter the SEV, I was able to change out of my dirty field shirt and into a clean t-shirt. I was able to stretch out without a heavy backpack on and I even stood in front of the air conditioning vents for a few minutes to help me cool off. Although we don’t have much time to “relax” after an EVA (because we need to head to our next site), it is much more comfortable to sit in a clean t-shirt without a backpack on while navigating and driving (and even eating a snack). Due to the ability to take a break between EVAs, the SEV and its suitports make it reasonable for us to plan missions of a month or more, without causing the crew to suffer from exhaustion.
