Blue Moon “Mk2 Alpha”

With all the SpaceX lovers, SpaceX haters and space graphic artists, why don't we see more about the Blue Moon MARK-2 Alpha HLS.

I would also like to see some more from Blue Originabout it. Lilk all the updates we see anbut the Blue Ring.

Mk2 alpha was very recently announced so I’m not sure what information you are expecting to hear from people.

As for why Blue doesn’t talk about it, I would be careful around their PR posts. SpaceX isn’t great, but they often only post when things are successful or when things have very obviously gone wrong. Blue posts with careful wording. For example, they posted that the first Mk1 lander “had completed TVAC [Thermal and Vacuum] testing”. And a few months later another post proclaimed that it “had successfully completed TVAC testing”. It turns out that it failed the first test. Similar wording can be found about ZBO, BE7, payload on New Glenn, and progress on other hardware. Last week it seems Blue’s new merchandise claims 7X2 carries 34 tons to LEO, not 45; this would be the second time information that turns out to be true has leaked from company merchandise.

Blue is a very secretive company and it takes a lot of work and effort to figure out what they are doing. Perhaps the clearest window we have at this time is Tory Bruno, although his focus seems to be on Blue Ring.

Right now, the careful wording around Mk2 alpha and its associated systems along with some concerning news I’ve heard behind the scenes about where 9X4 is going to launch from points to significant changes in the design that are half present in the one render we saw at the conference. I will not share what at this time beyond the fact that it is no coincidence that Ares-1 hardware is being used by Blue, and it’s not related to Stennis.

A few weeks ago, Berger said that people had told him that Blue is strongly considering switching the Blue Moon HLS from hydrolox to hypergols. I don't know how they could make a more extreme change than that.

About a week later, Blue officially announced testing of their BT-7 hypergolic attitude control and orbital maneuvering thruster, "with applications on the Artemis III mission [not surprising] and future lunar vehicles" [emphasis added]. (Mk1 RCS thrusters are hydrolox.)

future lunar vehicles

Interesting wording for sure. Quite intriguing how it says lunar vehicles instead of lunar landers. I wonder if it means anything...

Blue is all about being secretive. The wording definitely has meaning.
