Trump should've been on board. They could've saved the fuel needed for the return ๐Ÿ˜†

I'll be the actually guy because it's pretty cool but there's no fuel needed for the return since the moon's gravity did the job to turn around Orion and with inertia plus Earth gravity Orion will essentially fall back to Earth.

The whole thing is actually quite similar to throwing a ball in the air, it goes up slowing down until it turns around and comes back to you. On a different scale but the idea is quite similar so the only energy truly needed is the initial push (plus a few trajectory adjustement).

By the time you enter an orbit around the Moon (actually once you start a capture burn), you will need fuel to return. The free return is only a contingency for something going wrong on the first part of the mission. Also I am a bit foggy on whether a safe reentry is possible from a free return trajectory without any mid course correction burn on the way back. (Possibly that can be done with RCS only, though, which you need to put the spacecraft in the right attitude to survive reentry anyway)

Well, thankfully they saved us from the disappointment

Yet stille they had to sit there, orbiting the moon, and listen to him talk to them like they were best friends (and pretend like they liked it)

I heard they didn't do much pretending, but I didn't see it first hand.

Well they did clap and seem happy but I guess it's all for show considering he can close down their place of work and already has warned cuts to it

And he still called them last night.

At least they had some peace and quiet while they were behind the Moon.

Hope humanity is still here when they get back.

Or maybe it's time to call it

they will have a prime view of the mushroom plumes from the nuclear bombs going off :)
