This is excellent, and it makes me want to see the landing vehicle that carried them!
One tiny issue that has nothing to do with the vehicle design per se is the use of the red NASA "worm" logo rather than the "meatball". The red-letter version has been retired from use for about two decades now, in favor of the older round blue one: [link] [Wikipedia's page on NASA Insignia]
Wonderfully evocative illustration, otherwise. Great work!
