Mission day 12 was a continuation of the exploration of the Conch Reef environment surrounding the Aquarius habitat to sample locations discovered during mission day 11. To assist the topside scientists, the ROV (Remotely Operated Vehicle) was operated in “fly” mode which means that it was neutrally buoyant and was better able to track the aquanauts in the maze of coral reef fingers found in the fore-reef zone. The fore-reef zone is the seaward side of the reef where corals that can grow in high-energy environments are found.

For more information on the different reef zones, visit Stanford University’s Microdocs project for an overview and short documentary.

During the NEEMO 14 mission, Project CASPER (Cardiac Adapted Sleep Parameters Electrocardiogram Recorder) completed mission objectives and collected scientific data with regard to a sleep experiment which built upon lessons learned from spaceflight information. The newly gathered data set focused on the Aquarius crew during the NEEMO mission.

CASPER monitors the sleep stability of the Aquarius crewmembers by using the electrical activity of the heart. Each crewmember wears CASPER for four nights during the mission. This captured data gives a representation of the changing sleep stability of the crew as the mission progresses. The activity measured the medical data using the LifeShirt which the crew wore during the night.

Monitoring the sleep stability of the crew is important both for NEEMO and spaceflight because if the aquanauts suffer sleep disruption it can affect everything from mood, to concentration and memory, which could have a negative a effect on the mission. CASPER offers a portable, practical and repeatable method of monitoring sleep stability in a spaceflight and space analog environment like NEEMO. For more information on Project CASPER, check out the Project CASPER website.

Mission day 12 outreach activities included a live interview between astronaut Dave Williams (at the Baker Space Institute) and astronaut Chris Hadfield. Also, there was a joint NASA/CSA one-hour press conference with Astronaut Chris Hadfield which was audio streamed live on

While these interviews were occurring with the IVA crewmembers, our divers were also supporting an educational event that represented different gravity pulls. For example, one of the aquanauts was weighed to lunar gravity, one was weighed to Martian gravity, and our support diver, Brian, was weighed to a potential asteroid gravity. This awesome demonstration will be uploaded to our YouTube channel at

Mission Day 11 marked the first day of exploration of the Conch Reef environment surrounding the Aquarius habitat. During the extravehicular activities (EVAs), the aquanauts wore the life support mockups and added weights to their diving suits to simulate walking on the lunar surface. During these missions, the crew, along with the ROV (Remotely Operated Vehicle) evaluated science protocols for mapping and sample documentation and collection. The ROV provided situational awareness of the crew’s activities to the aquanauts and the topside science team.

The morning EVA crew mapped an area surrounding a coral sand pathway 400 feet long and documented the health and diversity of the coral fingers on either side. The afternoon EVA crew picked up where the morning EVA crew finished and continued to map and characterize Conch Reef. At the end of the day, the crews had identified and located important sampling sites for mission day 12 geoscience exploration activities.

Our education and public outreach efforts have stayed focused on the media today as Tom, Steve, and Chris were interviewed by several journalists. News coverage of NEEMO continues to spread… More articles will be out this week and after the mission as we continue to spread the word about NEEMO 14!

During mission day 11, the Alameda High School in Colorado was able to tie into the Aquarius habitat to speak with Tom. They asked very interesting questions about the purpose of the center of gravity (CG) rig, the reason for all of the EVA tasks, how storms affect the habitat, and why the injured crewmember mockup is being used.

Speaking to Alameda students

The students from Alameda High School in Colorado were able to call directly to Aquarius and visit with astronaut Tom Marshburn.

We also had the opportunity to go with the topside boat to support diving activities! It was cloudy and there was rain just waiting to let loose… but while we had the opportunity to be in the water, the visibility was amazing. We were able to snorkel above the Aquarius and watch as the crew and support divers worked on their EVA tasks.

Storms out at sea covered the sky with dark grey clouds today… Nonetheless, we have a crew underwater, so our dive team was ready for action!

Chris and Steve went out in the morning and Tom and Andrew followed in the afternoon. Mission day (MD) 10 extravehicular activities (EVAs) were similar to the activities and tasks performed during the EVAs on mission day 4. The crew wore the life support backpack mockups, and added weights to simulate working on the lunar surface in one-sixth of the Earth’s gravity. The crew performed many different mission objectives, such as entering and exiting the ascent module, transferring payloads from the sea floor to the lander deck, and moving the injured crewmember mockup.

The big difference in these tasks, compared to earlier in the mission, is the 20-minute delay in communication with our topside support team and Mobile Mission Control Center, as well as the lack of audible communication with any of the support diving team. This delay was instituted during week 2 of the mission, in order to simulate the delay in communication that would happen on a mission to Mars. During this EVA, the only people with whom the EVA crew could speak while performing their tasks were the other aquanauts, who were monitoring progress from inside the Aquarius habitat.

Our Aquarius team members have become so familiar with each other and their unique ways of performing and thinking, that all of the activities went off without a hitch. Mission day 10 was an EVA success!

We’d also like to mention that several of the students who have been able to view and participate in our education outreach activities have contacted us to express their appreciation, so we’ve included their comments in this blog. We are so happy to share the NEEMO 14 activities with all of you, and thank YOU for following along!

Brandon M: I think it is so amazing that the technology is so amazing to talk to people all the way around the world.

Nathan G: The astronaut under water was amazing. I think it was a good experience because it shows how astronauts train under water.

Melissa O: It was a great opportunity to talk to an astronaut. I am so glad I go to a NASA Explorer School.

Ryan L: This was a great experience to take part in.

Andrew G: It was interesting talking to aquanauts and learning what it is like to live in there [the Aquarius] for two weeks.

Leland K: I think it is really exciting to go underwater 60 feet for two weeks and see all the sea life but it will be cool when we go to the moon…

Corinna N: I think it is a wonderful experience to talk to astronauts underwater! A once in a lifetime chance! And learn why they are there!

Libby E: When I was asking my question the aquanaut left his microphone on and I could hear my voice in the background. It was pretty cool.

Nikayla B: That’s amazing how you can talk to us while being in a total different state and under 60 feet of water! I want to be part of NEEMO someday.

Jessica W: I thought it was very interesting to see the aquanaut in the water and having the aquanaut answer our questions about the NEEMO expedition.

Miranda I: It was so epic. It was such a good experience like I learned so much like you don’t even know!

Stevie E: It was a once in a lifetime experience that I will never forget! Epic!

Erryn A: I think watching the NEEMO video was fun: learning about the place and where they live when they are under the sea is cool. I wish I could be under sea like the NEEMO people.

Antonia D: It was awesome being able to talk to someone on the other side of the United States 60 feet under water. I’ll never forget it. It was cool to see an aquanaut swim past the window.

Gustavo L: It is great to be in a NASA Explorer school. You get more opportunities than other schools.

Andy W: (with a drawing of a couple dinosaurs) I, personally, found the whole idea to be quite incredible. Oh, the things technology can do.

Donny O: I really liked the live feed because it as a once in a lifetime experience and it was cool to talk to someone out of state.

Dallas M: I really liked it and it was interesting listening to what they do and how they do it.

Only a few Mission Days left… keep watching! We have more Remotely Operated Vehicle (ROV) activities happening on MD11!

NEEMO 14 Crew Journal: Mission Day 10

I’m the Commander of this underwater team. Here’s what I’ve been thinking about:

Keep Your People Safe – learn the risks, understand the goals, and then be relentless in making things as safe as possible, never being afraid of improvement. Where’s a better place for that? What will we do when that thing breaks?

Enjoy Yourselves – if people believe in what they are doing and in each other’s company, they will stay healthy and happy longer. Find common things for the team to believe in that are greater then themselves, and give them time to have fun with ideas.

Get the Job Done – know what you want. Keep the schedule out in front, constantly re-evaluate priorities vs time, be unafraid to stop when done, but push it when needed. Contentment in shared accomplishment is a wonderful drug.

Is the Building on Fire? – let things develop, and delay negative reactions. If someone is going plus or minus 90 degrees of you, you’re headed the same direction.

Stay in Touch – none of us are in this life alone. Listen to each other, say what you are doing and feeling, and don’t hoard amazing experiences.

– Chris Hadfield

NEEMO 14 Mission Day 9

Topside in Key Largo, Florida!

What a beautiful day to be at sea! After many days of high waves, wind, and “cloudy” conditions underwater, today the sky was clear, the waves were flat, and our topside team and Aquanauts were ready for another fantastic NEEMO day!

Today the crew finished the last of 6 days of evaluations and tests to determine how lighter or heavier weights and the placement of the weights affected their ability to work. The Moon’s gravity is 1/6 that of Earth, so if you weigh 60 pounds on Earth, you would only weigh 10 pounds on the Moon! During our underwater tests, to simulate weights of 200, 300, and 400 pounds (like what you would weigh on Earth with your spacesuit and life support backpack), we added 1/6 of those weights to the crew to simulate Lunar gravity conditions. So, here’s a test… how much weight did we put on the Aquanauts to make the 200, 300, and 400 pound weight conditions feel like Lunar gravity???

If you answered 33, 50, and 67 pounds, you got it right!

As you might expect, the crew preferred the lightest weight condition overall. But surprisingly, the lightest weight was not always the easiest to work with. For tasks such as shoveling or turning a crank, the simulated 400 pound weight (really 67 pounds) was preferred because it helped them exert the force they needed to complete their task. However, while walking around on the ocean floor and climbing the lander ladder, the crew performed most efficiently while wearing the lighter weight.

Working out with the “400 pound” weights… well, probably the light weights 🙂

Wearing different weights, the crew performs tasks from shoveling, to walking to climbing.

Today was also another big day for our education and public outreach events…

During his morning extravehicular activity (EVA), Chris did a special “shout out” to students and teachers at the Chris Hadfield Public School in Canada, connecting to an event with fellow Canadian astronaut Dave Williams. The school connected to Chris’s diver camera (click the “Red Diver” camera on the Aquarius webcam page) and Chris spoke briefly about being an aquanaut, gave a quick tour of the view from the lander deck, and introduced Tom (also out on EVA) and Nate (habitat technician and support diver assisting during the EVA activities). What a special moment, and as we watched from topside, we all decided that we wished we had that kind of cool experience when we were in school! Check out the awesome video.

We conducted one more Digital Learning Network event in the morning. Andrew talked to students from The Odyssey Academy (Bryan, TX), Richland Middle School (Richland Hills, TX), and Milstead Middle School (Pasadena, TX). This DLN event may be viewed on Youtube. Unfortunately we had a brief network outage, but our topside communications team was quick to restore the connection so that Andrew could continue to talk to these students. This was a particularly special event, as the students that connected to Aquarius were the same groups that Dr. Mary Sue Bell and Amanda Knight talked to while driving the Remotely Operated Vehicle (ROV) last week! These students created patches for the NEEMO 14 mission, check them out!

In the afternoon, Chris conducted an event with students in Canada and discussed the purpose and definitions of analogs; how diving compares to spacewalking; and the value of staging an underwater mission. There were several schools across Alberta, Quebec and Ontario that participated in the live event, including English Montreal School Board, Lester B. Pearson School Board, Sir Wilfred Laurier School Board, Riverside School Board, and Ministry of Education of Alberta.

Overall it was a very successful day of EVAs and outreach activities! We’ve uploaded videos on YouTube and more photos on Flickr, so make sure to check it out!

NEEMO 14 Crew Journal: Mission Day 9

What a great day down here in Aquarius. It was a typical NEEMO day. Lots of good data collected during the extravehicular actvities (EVAs) and some very cool education outreach events. The commander pulled out his collapsible guitar which was last played on the Mir Space Station, very cool!

During one of the outreach events he demonstrated what happens to a can of Pringles when they aren’t properly vented before being sent down to Aquarius. Although they started out as potato chips, they ended up as potato bits. The increased pressure inside Aquarius crushed the can since it was a sealed container. It served as a great learning tool for the school children that were taking apart in the event.

The EVAs were very productive. Andrew and Steve opted to extend their dives by one hour to achieve the mission objectives. Although I have not been able to join them on the EVAs, I constantly monitor their audio, dive helmet cameras and other situational cameras. The work the team is doing is great to watch and I feel a great sense of pride of being a part of the NEEMO 14 team.

My favorite part of day 9 though was the fact that we aren’t in decompression. The majority of Aquarius missions are ten days long, so decompression normally starts on “day 9”. Since this is a 14 day mission we won’t start decompression until day 13. So that means I still have 4 more days before my “living the dream” experience starts to come to an end.

Good night from Conch Reef.

NEEMO 14 Crew Journal: Mission Day 8

Mission day 8 draws to a close and it is clear to see that we still have some of the coolest jobs on and off the planet. The best thing about being down here with so many different personalities is getting to know them. One of my favorite things to do in life is to laugh, and with this bunch of guys, that’s an easy thing to do.

I’m going to fill you in on what I have observed – only my opinion, not Aquarius’s and most definitely not NASA’s. First we have two PhD’s, one MD, one Colonel, and two habitat technicians. The only thing more intimidating is having a planetary geologist working beside you.

These are easy going, humble guys with great stories to tell. And it’s been great hearing the background stories on these fine gentlemen, where they’ve been, what they have seen, how many times their guitar has been around the world, how many hits they have on Google, or how many crewmember mockups they’ve hauled up a rope.

These guys are truly amazing. Their lives are rich, interesting, and would make many green with envy. Gentlemen, somewhere out there is a child calling you hero, and changing their dreams to follow in your footsteps… my hat is off to you; and James.

Mission Week 2 brings a new set of challenges to NEEMO 14, as we have switched to “delayed communications,” similar to what we would do if the crew was living on Mars. We are simulating this by sending and receiving emails with a 20-minute delay. We are also recording video messages each day to send to Aquarius in response to the crew’s video to the topside team. Aside from that, the crew is completely responsible for keeping the mission timeline on track and ensuring that the extravehicular activities (EVAs) are completed successfully and according to plan.

Lifting the exploration vehicle

During Mission Day 8, the crew began the task of lifting the exploration vehicle from the ocean floor with the large crane.

Today’s EVAs kicked off with Steve and Andrew in the morning, and Tom and Chris in the afternoon. More center of gravity (CG) positions were evaluated today. The visibility was a bit better, but as Commander Chris Hadfield described in our last live morning meeting with the crew for the week, the view out of the porthole window looked like there was a “blue fog” outside. Our diver support team was relieved that the sea conditions resulted in only 2-4 foot waves (compared to last week’s range: up to 8 feet). You can imagine that it’s a lot more fun to be underwater when the seas are that rough!

Divers gather for a photo

Any type of extreme mission requires many aspects of support, from mission control, scientists, doctors to support divers. Our divers gather around the exploration vehicle for a photo op.

Today was also a big day for education activities as the Aquarius crew connected to several schools through NASA’s Digital Learning Network programs. These programs were webcast live on the internet, but, if you were not able to check them out… don’t worry! We’ve uploaded them all to our YouTube site.

Astronaut Tom Marshburn was interviewed by Ronnie Crownover Middle School (Corinth, TX), Stephen F. Austin Middle School (Bryan, TX), Space Center Intermediate (Clear Lake, TX), McMillan Junior High (Wylie, TX), Travis Elementary (Baytown, TX), and The Harry Eichler School (Queens, NY) during the morning EVAs.

Students chat

The Harry Eichler School’s fifth grade students were amazed as they connect to Houston and to the Aquarius to chat with Astronaut Tom Marshburn.

Aquanaut Steve Chappell spoke with students from Magnolia High School (Magnolia, TX), Northwest High School (Justin, TX), Kadoka Middle School (Kadoka, SD), Dunbar Middle School (Lubbock, TX), Cole Middle School (Lancaster, CA) and Key Peninsula Middle School (Lakebay, WA).

Check out what the students had to say on the NEEMO 14 Facebook page.

During our evening debrief, we waited to receive the crew’s video briefing of the days events and questions they may have. As the video began rolling, each crew member was wearing a different silly hat… and if they didn’t have a hat, they made one out of whatever was laying around the habitat. They concluded the debrief with a challenge to the Mission Control Center support staff to be more creative than they were.

So, to finish up our evening, we all put on snorkeling masks and snorkels. At first, during the video, we were are very seriously and intently working away… until the Little Mermaid music broke into the background and we all put on a show. It was a great way to end a very long day! And it is such a pleasure to work with professionals who know when it’s time to let loose… just a little.

NEEMO 14 Crew Journal: Mission Day 6

Settling In

We’re nearing the halfway point of our mission, settling into a comfortable routine. The habitat technicians start the day, awakening to check the health of our underwater home, and we all soon rouse to begin our daily regimen.

We first breeze through our life sciences data takes so we can begin breakfast. The process for six crewmembers on a small vessel begins to resemble a small school of fish – a loosely choreographed activity as we swerve around each other writing email, preparing coffee, eating granola, and cleaning little spots and spills. Saying “excuse me” or “sorry” is becoming needless. Small collisions are so common in such close living quarters – they become unavoidable, expected, and barely noticed. One crewmember at a time steels himself and departs for the inevitable plunge into the deep ocean for a trip to the “outhouse,” to return to the team, smiling and refreshed.

Amazingly, the activity at once converges, and all crewmembers are ready for the morning conference with the topside. We then disperse again as we prepare for the first extravehicular activity (EVA), each preparing for our roles for the task, and like a single organism, again converge with all attention focused on the suiting up of our EVA duo.

Our attention remains welded to the checklist, video cameras, and communication protocols, until several hours later when both crew members are back inside and we prepare hot meals and drinks. The vigorous physical labor and successful completion of good work are essential elements of a good day. More science, more writing, perhaps a nap, before the second set of EVAs. End of the day is a mirror image of the beginning, with dinner replacing breakfast, and activity slowing as we contact friends or families, and perhaps take some time to muse about life out the window. The habitat technicians are the first to prepare for sleep, and then one-by-one the crew members retire their laptops, lay down their notes, turn off their night lights, and fall asleep to the surge and sway of the ocean.

NEEMO 14 Mission Days 6 and 7

Topside in Key Largo, Florida!

On Saturday, mission day 6 (MD6), the NEEMO 14 crew completed another day of extravehicular activities (EVAs) and mission activities. Once again we experienced rough sea conditions that affected the visibility underwater, which was limited to approximately 15 feet. The strong currents definitely impose a greater fatigue on the crewmembers as they perform their underwater tasks. In addition, the aquanauts are loaded with different weight configurations, some of which make tasks easier to perform, and others, more difficult.

The mission activities improve with each mission day as the crew and mission support teams learn how to work together as a team… communication is good, and the EVAs are moving effectively, safely and on schedule.

Aquanaut and flag

Despite rough sea conditions, complete isolation from the surface and close quarters, the aquanauts are still excited to be participating in the next generation of technology development.

As the official part of mission day 6 came to a close, the aquanauts set out on their own underwater adventure… a night dive!

During mission day 6, the aquanauts were able to suit up with lights added onto their helmets and perform a night EVA.

Mission day 7 was a rest day for the aquanauts and topside teams. Rest was much needed as mission week 1 came to a close and we prepped for mission week 2: destination Mars!!! As of mission day 8, the NEEMO 14 team will begin working the mission with delayed communications to simulate the communications delays we would experience if the crew was on Mars. The objective of this activity is to simulate how to run a mission when the crew is on a surface so far away, that they cannot speak to the mission control personnel in real time. Stay tuned for more details and keep checking our Flickr and Facebook pages for more NEEMO 14 pictures and information!
