Fourteen Days on “The Moon” in Arizona

Posted on

It’s a quarter of a million miles to the Moon, we’ve got fully charged batteries, half a pack of space food, it’s daytime, and we’re wearing spacesuits. Hit it.

Last week I returned home from the adventure of a lifetime, a simulation of a mission on the Moon where I lived and worked inside NASA’s Lunar Electric Rover (LER) for 14 days during NASA’s Desert RATS (Research and Technology Studies) analog field test.  For the last 12 years, Desert RATS has been testing new concepts for spacesuits, robots, vehicles and tools in rugged environments that are similar to the surfaces of the Moon and Mars.  This year, Desert RATS tested how a crew of two would live and work inside a small pressurized rover (the LER), dock with various equipment and robots, and use of the rear-entry suitport for donning and doffing spacesuits.  These concepts are being tested in an effort to provide Astronauts new ways to explore the lunar surface efficiently and effectively for long duration missions.  The LER provides the crew the necessary shelter and safety to live away from their original landing site, while the suitport saves valuable time and resources by allowing Astronauts to slide in through the backpack of the spacesuits, which are attached to the outside of the rover, and be on the surface in less than 15 minutes.

For our mission, Astronaut Mike Gernhardt and I explored Black Point Lava Flow, north of Flagstaff, Arizona.  These 14 days were packed with activities that would be completed by a crew during a real mission.  Days 1 and 2 were spent checking out the vehicle and supplies, rendezvousing with ATHLETE, and docking with the Portable Utility Palette (PUP).  Days 3 through 10 were spent studying the local geology, where we followed a series of traverses planned by the Science Team.  Using only a black and white satellite image of the area for planning, specific locations were selected for us to visit and collect samples based on a series of science questions and prioritized objectives.  Since I was the crew geologist, this was obviously my favorite part of the mission.  My favorite view was at the far end of the lava flow looking over a river valley towards the rock formations to the east.  On days 11 through 14, we docked with a portable habitat being carried by ATHLETE, moved regolith around with the LANCE, and rescued another two person crew from a broken down LER.  Four of us spent 24 hours inside one LER simulating a rescue mission on the Moon.  Surprisingly, there was still a lot of room inside with four people.  We each took turns driving and sleeping through the night.  By the time the mission was completed, Mike and I had driven over 120 kilometers (75 miles) and spent over 300 hours inside the LER.

Daily life inside the LER was very fun and it was convenient to have everything you needed literally within arms reach.  Each morning we tagged up with Houston to go over our daily plan and had our breakfast.  Our meals consisted of real space food and dehydrated camping food.  There was a “sink” with hot and cold water to make our meals with, which were actually really tasty.  The bathroom was a glorified camping toilet, nothing fancy, just some special plastic bags.  Our personal gear and food was stowed in lockers within the side hatches and beneath the floor boards and bunks.  We exercised for at least one hour each day using a stationary bicycle machine and resistance bands.  Special clothing with silver lined threads to kill odors allowed us to reuse the same set of shirts and shorts for the entire mission.  At night, we unfolded curtains attached to the walls and ceiling to create individual sleep stations which were both dark and sound proof.  After a good night sleep, we woke up and did it all over again.

This mission would not have been possible without an absolutely amazing ground support team who followed us every step of the way and served as the mission control back in “Houston”.  This experience truly shows that human exploration of the Moon takes more than just the crew, but relies heavily on a dedicated and hard working team back on the ground to make it all possible.

  1. Cool post! I understand the “RV” is about 350 square feet inside? That doesn’t sound too terrible, actually. It’s bigger than my tent, but I’ve never spent 10 consecutive days inside it. . .

  2. So what does the space food taste like? Is it small pills like they show in the movies? 😛 I’ve eaten plenty of dehyrated camping foods, I usually just try to eat what nature provides me in the field tho. btw, great blog post =D

  3. Axel,

    We had “real space food” and camping food to eat during the 14 days. The real space food is stuff that is flown on the shuttle/ISS and was normally snacks and side dishes that didn’t need to be rehydrated. These were hit or miss. I liked the tapioca pudding, applesauce, and BBQ Beef Briscuit, but was not a fan of the turkey or salmon. The camping food was delicious. My favorites were the lasagna and the chicken teriyaki. The great thing about having been in college/graduate school for so long is that I am used to semi-bland, instant food, so I felt right at home. The key thing with food in space is you want it to be ‘dry’, the ‘wet’ foods are heavy. Fresh foods won’t last long, besides I just want calories so I can explore, I’ll eat the steak and lobster when I get home.


  4. Hi Amelia,

    I don’t remember the exact square footage off the top of my head, but it is roomy. The individual sleep stations are about the size of a one person tent, but with nice high ceilings and storage locker. There is enough room in the center aisle of the LER to stand straight up without hitting your head on the ceiling (I’m 6’1″). There is enough room for privacy even when we had 4 crew in there during the rescue mission. Not bad for what looks to be a small space. The great thing about the LER is that we can get outside through the suit ports.
