NASA Is Seeking Ideas for Rescuing an Astronaut from the Moon
Space exploration is a dangerous business, especially when squishy living organisms, such as humans, are involved. NASA has always prided itself on how seriously it takes the safety of its astronauts, so as it gears up for the next big push in crewed space exploration, the Artemis program, it is looking for solutions to potentially catastrophic situations that might arise. One such catastrophe would be if one of the Artemis astronauts was incapacitated and couldn’t return to the lander. The only person who could potentially be able to save them would be their fellow astronaut, but carrying a fully suited human back to their base of operations would be a challenge for an astronaut similarly kitted out in their own bulky suit. So, NASA decided to address it as precisely that – a challenge – and ask for input from the general public, offering up to $20,000 for the best solution to the problem.
The challenge, “South Pole Safety: Designing the NASA Lunar Rescue System,” was announced on November 14th and accepts entries until January 23rd, 2025. It awards $45,000 to at least three winners, including $20,000 to the first-place winner. So, what does the challenge actually involve?
The work product is a design document for a system capable of moving fully suited astronauts at least two kilometers up a 20-degree slope without being attached to a rover. Oh, and it has to be able to operate in the harsh conditions of the lunar south pole.
Fraser discusses what makes the lunar south pole so interesting.
Typically, a fully suited human wearing the new Axiom Extravehicular Mobility Suit, the new spacesuit explicitly designed for the Artemis missions, will weigh around 343 kg (755 lbs). However, lunar gravity is only about 1/6th that of Earth’s, so it will feel more like they weigh 57 kg (125 lbs). That’s still a lot to carry but much more manageable.
However, it’s probably infeasible for the other astronaut to fireman carry their unconscious comrade over that distance, especially since they are wearing their own spacesuit. So it’s up to technology to do the job. To do so, it will have to evade the pitfalls (in some cases literally) of the lunar south pole.
One hazard is the extreme temperatures—they can range from 54 C in full daylight to -203 C at night. Any materials used in the (especially electronics) would, therefore, need to be able to withstand such wild temperature swings.
Dealing with lunar regolith for this challenge will be difficult, as Dr. Kevin Cannon discusses how annoying it can be.
Other hazards include razor-sharp lunar regolith, which is expected to cause havoc on most moving mechanical systems on the Moon. Navigating around craters and giant boulders while hopefully dodging micrometeoroid impacts adds to the complex nature of the rescue environment.
A panel of experts, including some NASA engineers, will judge this competition. Their scorecards will include categories like the overall mass of the solution, its ease of use, and how much it impacts the suit design, if any—luckily, treating the fallen astronaut while on the move back to safety is outside the scope of this challenge.
Suppose you’re interested in participating, potentially earning you or your team tens of thousands of dollars. In that case, NASA is accepting submissions through the HeroX portal (commonly used for public challenges) through January 25th. Maybe someday you’ll get to see your creation on the surface of the Moon—even if it will hopefully never be used.
