NASA NEEMO 10 MD 4/5 Topside Report July 25 & 26, 2006 – Mission Day 4 & 5 – Topside Report
An important question we face prior to returning to the moon is how to maximize the human and robotic resources we have. We have successfully demonstrated that human operators on Earth can control robots on a distant world with numerous Mars missions. We routinely use robotics on the space shuttle and space station that are controlled by in situ astronauts. And we have the experience of hundreds of suited spacewalks. What we don’t have much experience with is optimizing between the three options. Crew time is precious, so it’s advantageous to move operations to ground controllers wherever possible. The ground has the time delay to deal with, but they have advantages like being able to work all night long while the crew is sleeping. In short, there is always a tradeoff between the more precious crew time and the (expected) higher efficiency of crew work. How to optimize the split of work between spacewalk work, crew controlled robotics, and ground controlled robotics is an important question that needs to be answered prior to returning to the moon.
The remotely-operated vehicle (ROV) on this NEEMO mission performs the role of the robot. It can be a surface rover, or a free flyer (resembling the end of a robotic arm.) It can be controlled by the control center in Houston, or the in situ crew. As the mission continues, we have been experimenting with all options and documenting lessons learned to help answer the larger question of how best to split work. Following on the work done on NEEMO 9, we have designed exercises to answer these questions on NEEMO 10. Over the course of multiple missions we expect to have a significant database to help drive our lunar operations concepts.
Just as on the International Space Station, future inhabitants of the moon or Mars will need periodic cargo vehicles to resupply them with the essentials they need to live in such a harsh environment (air, water, food, etc.). The cargo vehicle will be targeted to land close (but not too close!) to their base. It’s also likely that the cargo vehicle will have a homing beacon. So a task astronauts may one day face will be to follow the homing beacon to their cargo vehicle with fresh supplies.
In the last two days we have exercised all of these concepts with different exercises. The Mission Control Center (MCC) team in Houston did a timed exercise to find out how long it took them to find different markers deployed nearby with the ROV. Later the suited crewmembers performed the same task, and the respective times were logged for comparison. Later the MCC team navigated the ROV around the natural obstacles of the reef to a homing beacon hidden hundreds of feet in the distance. This exercise was repeated with suited crewmembers being vectored by the MCC.
Obviously one of the primary science tasks on the moon or Mars will be collecting rock samples. We envision that the crew will find samples on their excursions, the planetary scientists in the MCC will analyze them remotely, and later send the crew back to those locations that looked most interesting to get more samples. This scenario was exercised today, with a planetary scientist from the Astromaterials Research and Exploration Science (ARES) group at Johnson Space Center playing her role.
Finally, the crew supported a first ever linkup with representatives of the Japan Marine Science and Technology Center (JAMSTEC). This government institution is chartered with many of the same responsibilities as the National Oceanic and Atmospheric Administration (NOAA) in the United States. It was a unique linkup by having representatives of JAMSTEC and NOAA, the Japan Aerospace Exploration Agency (JAXA) and NASA together discussing common goals. Perhaps this will be the first step for more meaningful collaboration and partnerships between the agencies in the future.
