Blue Moon, the recent announcement of an uncrewed lander by Blue Origin, had flare and pomp. A starfield surrounded the select audience as they watched Jeff Bezos, the richest man (okay, if you count his family) in the world, deliver an anticipated announcement. They waited patiently as Bezos gave his usual spiel about Earth being the best planet, about the criticality of reusability, about a trillion people living in O’Neil colonies, about moving heavy industry to space. Then Bezos unveiled…
An expendable descent stage with less payload capacity (3.5 tons) than the Apollo LM truck variant (5 tons). Because it uses liquid hydrogen, it’s very tall and therefore needs a sophisticated mechanism for unloading payloads.
It was so anti-climactic. Everyone knew Blue Origin was working on this lander, I was sure it was going to be something more important or at least *innovative*. I’m not sure if the rocket engine is pumpfed or not, but the lander is designed as if it’s pressure-fed, with Apollo-like large round tanks with external structure.
Its example mission is… landing several smaller payloads simultaneously. Basically, competing with all the smaller lunar lander companies out there. Super disappointing there as well.
It’s like a tiny, uncrewed version of Altair with all the drawbacks but without the advantages of a 16 ton payload capacity. And sure, they showed an ascent stage on top of it, but that appears to be provided by NASA.
In fact, let me list off some concepts I think are better:
1) Starship. Obviously. Fully reusable, much larger payload capacity, crew capable, and being crudely prototyped right now in Texas, not just made into a fancy mockup.
2) The reusable Lockheed Martin lander. Dinospace is not supposed to be this much better, but this is a lot more interesting than Blue Moon.
3) ULA/Masten Centaur/Xeus. More payload capacity, still hydrolox, much closer to the ground. Looks to be a more efficient design. Some of the hardware already exists in some form.
4) Altair. At least they were trying for more capability than Apollo.
5) Apollo LM/LMtruck. 5 ton payload capacity, much closer to the ground. Crewed variant was the only one that flew, so it started out crewed.
6) The Soviet LK lander. Crasher stage FTW. Less payload, but the Soviets did a fine job systems engineering a clever way of dealing with the constraints they were given by the much-less-to-TLI N-1 rocket.
7) Various crasher/uncrasher lander concepts, as discussed here.
8) Delta Clipper on the Moon. If Delta Clipper had been successful, there was thought given to variants of it for Moon or Mars. If you have a SSTO VTVL RLV, why not refuel and go to the Moon? Basically, like Starship. Bezos hired a bunch of old DC-X folk. Why such a mundane lunar architecture?
Blue Origin gets like $1 billion per year from Bezos. Couldn’t they come up with something better than Blue Moon? Or at least something that didn’t look designed to squash the other small lunar lander outfits? A reusable upper stage? A reusable lander? Anything?
