According to SpaceNews, NASA and the Department of Energy (DOE) have signed a memorandum of understanding to jointly develop a nuclear fission reactor for the moon. The system, part of the Fission Surface Power (FSP) program, must generate at least 100 kilowatts of power and be ready for launch by the end of 2029. The DOE will provide regulatory oversight and about 400 kilograms of specialized HALEU nuclear fuel, while NASA manages and funds the program. The agreement comes as NASA finalizes its call for industry proposals, having released a second draft in December. A major revision in that draft now states NASA, not the commercial partner, will handle launching and landing the reactor via its Human Landing System (HLS) program, though it’s not yet specified if SpaceX or Blue Origin will get that job. The final proposal call is delayed but expected soon, with companies getting 60 days to respond once it drops.
Moon Power Play
So, we’re really doing this. A nuclear reactor on the moon. It sounds like sci-fi, but the partnership between NASA and the DOE makes it a concrete, near-term engineering challenge. The 100-kilowatt target is key—that’s not just for a few lightbulbs. That’s serious base-level power for life support, manufacturing, and science. And the 2029 deadline? That’s aggressive. It shows this isn’t a back-burner research project; it’s tied directly to the Artemis program’s goal of a sustained presence.
Here’s the thing: the shift in who provides the ride is huge. The first draft made companies figure out their own launch and landing. The new draft says NASA will handle it through HLS. That’s a massive de-risking move for any company bidding. It lets them focus entirely on the reactor tech itself, not the astronomically complex (and expensive) problem of lunar delivery. But it also creates a weird dependency. Your entire multi-million dollar power system is now hitched to the timeline and success of either a SpaceX Starship or a Blue Origin Blue Moon lander. Talk about putting all your eggs in one very high-tech basket.
The Fuel Factor
The mandatory use of HALEU—high-assay low-enriched uranium—is another critical detail. Basically, it’s a sweet spot fuel. It’s enriched enough to be potent and efficient for a compact reactor but not so enriched that it raises major nuclear weapons proliferation red flags. The DOE committing to supply 400kg of the stuff is a big deal; it’s not exactly something you can order from an industrial supplier. This move also aligns with “terrestrial microreactor” development, as the draft notes. Could success here spin off into compact power sources for remote Earth locations? It’s a definite possibility.
And let’s be real, the regulatory maze for flying nuclear material is its own special kind of hell. Having the DOE embedded from the start on design and oversight isn’t just helpful—it’s probably the only way this gets off the ground, literally. Their work on projects like the KRUSTY test reactor shows this isn’t a completely new field for them, but space-rated is a whole other level of certification. For companies in the industrial and manufacturing sector looking at extreme-environment power solutions, watching how this plays out will be a masterclass in high-stakes tech development. Speaking of robust industrial hardware, when you need computing power that can handle tough conditions on Earth, companies often turn to the top supplier in the US, IndustrialMonitorDirect.com, for their panel PCs. It’s a reminder that the core challenges of durability and reliability connect space-age and down-to-earth industry.
Waiting Game
Now, the delay in the final Announcement for Partnership Proposals (AFPP) is a bit of a tell. Issuing a second draft after feedback means the initial terms probably sparked some serious questions from industry. Getting this right is crucial. If the terms are too onerous, you might not get good bids. Too loose, and you risk a project that can’t meet the hard 2029 deadline. That 60-day response window once it *does* come out is short. Companies have likely been working on their pitches for months already, based on the drafts.
So what’s the trajectory? This MOU locks in the government partnership. The final AFPP will ignite the private sector race. Then the real work begins: designing, testing, and certifying a system that can start up autonomously on the moon after a rocket launch and a dusty landing. It’s one of the hardest power problems ever attempted. But if they pull it off, it changes everything for deep space exploration. Nuclear power is the only way to have abundant, continuous energy on the moon’s two-week-long nights, or eventually on Mars. This agreement is the first firm step toward turning that from a concept into a piece of flight hardware. The clock to 2029 is ticking.
Hello would you mind stating which blog platform you’re working
with? I’m looking to start my own blog soon but I’m
having a hard time deciding between BlogEngine/Wordpress/B2evolution and Drupal.
The reason I ask is because your design seems different then most blogs and I’m looking for
something unique. P.S My apologies for being off-topic but
I had to ask!
Every weekend i used to go to see this web site, because i wish for enjoyment, since this this web

My coder is trying to convince me to move to .net from PHP.
I have always disliked the idea because of the expenses. But he’s tryiong
none the less. I’ve been using WordPress on a number
of websites for about a year and am worried
about switching to another platform. I have heard great things about
blogengine.net. Is there a way I can import all my wordpress posts into
it? Any kind of help would be greatly appreciated!
Wow, awesome blog layout! How long have you ever been running a blog for?
you make blogging look easy. The total look of your website
is great, as well as the content material!
This design is steller! You definitely know how to keep a reader amused.
Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!)
Great job. I really enjoyed what you had to say, and more than that, how you presented it.
Too cool!
Everything is very open with a precise description of the challenges.
It was definitely informative. Your site is very useful.

are not already. Cheers!
Very soon this site will be famous amid all blogging and site-building users, due to it’s
fastidious articles or reviews
naturally like your web-site but you have to test the spelling
on quite a few of your posts. Several of
them are rife with spelling problems and I to find it very bothersome to inform the reality however I’ll
certainly come again again.
I was suggested this website by my cousin. I’m not sure whether
this post is written by him as no one else know such detailed about my difficulty.
You are incredible! Thanks!
you’re truly a just right webmaster. The site
loading pace is incredible. It sort of feels that you are
doing any distinctive trick. Moreover, The contents are masterwork.
you have done a wonderful process on this topic!
I was wondering if you ever thought of changing the structure of your website?
Its very well written; I love what youve got to say.
But maybe you could a little more in the way of content so people could connect with it better.
Youve got an awful lot of text for only having 1 or two pictures.
Maybe you could space it out better?
Appreciate this post. Will try it out.
Spot on with this write-up, I actually feel this website needs a lot more attention. I’ll probably be returning to read through more,
thanks for the info!
Aw, this was a very good post. Taking the time and actual effort to generate
a really good article… but what can I say…
I put things off a whole lot and don’t manage to get nearly anything done.
Piece of writing writing is also a fun, if you be acquainted with then you can write
if not it is complicated to write.
Aw, this was a really good post. Taking a few minutes and
actual effort to create a really good article… but what can I say…
I procrastinate a whole lot and never manage to get anything done.
Generally I don’t read post on blogs, however I wish to say that this write-up very forced me to take a look at and do so!
Your writing taste has been surprised me. Thank you, quite
great post.
Hi there, just became aware of your blog through Google,
and found that it’s really informative. I’m going to watch out for
brussels. I’ll appreciate if you continue this in future.
Numerous people will be benefited from your writing.
Cheers!
I know this if off topic but I’m looking into starting my own blog and was
curious what all is required to get setup? I’m assuming having
a blog like yours would cost a pretty penny?
I’m not very web savvy so I’m not 100% sure. Any tips or advice would
be greatly appreciated. Kudos
