NASA's plan to put a nuclear reactor on the moon

"The Moon awaits. After long decades in which no human being set foot on the lunar surface, we are heading back. And quite soon.

As part of the NASA-led Artemis program, astronauts are returning to the lunar environment as soon as 2024, with a view to ultimately establishing a long-term human presence on the Moon – a place we haven't seen in person since 1972.

To live and work on the Moon, though, astronauts will need power and plenty of it, and there's no power grid on the Moon.

While any number of creative solutions might be able to help fix that problem, for years NASA has viewed nuclear fission as the most practical power option for future astronaut colonies, and now the space agency is taking the next step in making a nuclear reactor on the Moon a reality.

"Plentiful energy will be key to future space exploration," says Jim Reuter, associate administrator for NASA's Space Technology Mission Directorate (STMD).

After years of investigating the possibilities for lunar nuclear fission under its former Kilopower project, NASA is spearheading a new drive in fission surface power research, working in conjunction with the US Department of Energy (DOE).

The two organizations are now putting out the call for American industry partners to submit design concepts for nuclear fission power systems that could run on the lunar surface and be ready to launch and demonstrate their potential on the Moon within the decade.

According to NASA, a small, lightweight fission system – capable of operation on a lunar lander or lunar surface rover – could provide up to 10 kilowatts of electrical power, which would be sufficient to satisfy the electricity demands of several average households.

In the context of lunar operations, power usage would be different to what households require on Earth, of course: running life support systems, charging lunar rovers, and helping scientists to conduct experiments.

According to the NASA and DOE brief, future fission systems will ultimately need to produce at least 40 kilowatts of energy, which NASA says could power approximately 30 households for up to 10 years.

At those anticipated levels, there should be enough energy not only to make a sustained lunar presence possible, but also one day to enable exploration and even colonization of Mars – which is the scientific stretch goal Artemis's endeavors are ultimately bringing us closer to.

In fact, NASA says today's research into lunar fission power systems could also help inform proposed nuclear propulsion systems that may one day enable astronauts to journey to the red planet on spacecraft traveling at faster speeds for shorter missions.

One step at a time, though, as we are still likely years away from seeing a lunar fission reactor actually working on the Moon. While NASA and the DOE have enjoyed some success with Kilopower prototypes in previous experiments, nobody has yet had a chance to test something like this on the Moon, which is where it counts.

To get us closer to that, NASA and the DOE will select the most promising design proposals it receives between now and late February 2022, and will help to develop those concepts for a 12-month period.

After those projects are assessed, what researchers learn will go on to guide the design and build of one final flight-qualified fission power system, which will be launched to the Moon on a demonstration mission, hopefully sometime this decade."

Then, at long last, the Moon should have the beginnings of its very own power grid – and humanity's base of operations in space will be on a new level to anything we've built before.

"The feedback and enthusiasm we continue to see for space nuclear power systems has been very exciting, and understandably so," says senior engineer Sebastian Corbisiero, the Fission Surface Power Project lead at the DOE's Idaho National Laboratory.

"Providing a reliable, high-power system on the Moon is a vital next step in human space exploration, and achieving it is within our grasp."

 

This is not a drill...This is not a drill.

 

Lol Artemis program. What's next, putting Matt Damon on Mars?

Quite big news this, and allow for better returning shuttles and flights towards Mars. Interesting to see how they will go about this without an obscene amount of water required mind you.

 

Wonder what the 1st moon based celtic supporter club will be called ?
Clangers No1.

 

Soup Dragon Emerald?

 

Surely it's Michael Collins CSC?

 

If you are talking about our sun it's nowhere near the biggest in the galaxy, but yes, you'd think solar power would be the way to go.

However it really depends what type of nuclear reactor they are thinking about, there are relatively safe ones that could be utilised, like a Thorium molten-salt reactor, but if they are going the usual route that has some very real potential issues with the amount of water that would be needed, the pressures and temperatures they operate at here are bad enough but a coolant leak in, essentially, a vacuum on the moon doesn't bear thinking about.

 

Change galaxy to solar system and you'd be right.

 

Yeah, it's very very far from the biggest in the galaxy. The biggest known star would engulf all the inner planets all the way up to, and including, Jupiter.

 

NASA always make things complicated.
What about a box of matches and some wid.
Well it worked for Matt Damon, and he was on Mars FFS.
Just burn *

 

Dr Evil done this years ago.

 

Makes sense really. Nuclear power done right is the most sustainable and efficient

 

Not great not terrible
