>>13171590i suppose i should have specified if anyone in a position to actually know anything claimed it desu...
>>13171608if i was going to be a big a sperg as you i would start greentexting about how you're a retard for thinking that moonship is going to return to leo even though shotwell was talking about a mission that explicitly required return to earth itself. but i'm not going to be that much of a sperg. instead i'm just going to gently remind you that if it's possible to transfer cargo in NHRO for earth return in the same way that starships can transfer propellant in NHRO and then return to earth. but i think you already knew that and you're just being silly.
i had just assumed that this apogee character knew what he was talking about on the 25 tons on the leo-to-moon-to-leo thing but upon further review the math doesn't add up. the round trip is going to be north of 11 km/s but for the sake of argument let's say 10, you'll see why.
take moonship's wet mass on wikipedia of 1320 tons and a specific impulse of 380s and a mission delta v of 10 km/s. you get a final mass of 90 tons, which, coincidentally, is apogee's posited dry mass for moonship at 11:20 in the video. looks like negative mass margins to me.
