If we were standing at the equator on the near-side of the #Moon, and looking straight up, we would see the #Earth and the #Orion spacecraft coming in from the left and crossing over to the right along the upper part of the blue trajectory, right before setting behind us, and then, after orbiting far above the side that's hidden from the Earth, it would reappear at the lower left, cross to the right, and go plunge far into a Terran ocean.

Phew… those earthlings…

Hm, I'm afraid the above is not very accurate: what I describe above would be the case if we were stationary in space and the orbiting moon passed right under our feet, traveling along its orbit; but from a point on the surface of the Moon, the trajectory would look quite different.

Are you sure? Since the moon is tidally locked if you were on the moons surface looking up the earth would appear suspended statically in space ( more or less) and I think that view is pretty much what the Orion capsule path would look to you. The background stars and other stuff would be spinning slowly around from right to left.

@helvick
Yes. The trajectory shown above extends to about 10 days. During most of that time the Moon is very far from the point where Orion will turn around it, but in the image above we see the trajectory as if we were already there and stayed there for the whole duration, which is not right.

Placing the camera in @ian 's Artemis II simulator https://artemistracker.mapki.com/ on the surface of the Moon could easily demonstrate this, but but at present it doesn't have such capability.

To make things clear again, the nice image above is a plot of the circumlunar trajectory seen from one specific *fixed* point along the Moon's orbit, not what one would see from the surface of the orbiting Moon.

The image below shows how #Celestia, https://celestiaproject.space/, sees #Orion from the Moon. At present, observing the spacecraft from there would be hard because the sun is almost behind it. Visibility will improve as the spacecraft approaches the #Moon.

@65dBnoise I've been known to tell a few people to 'go plunge yourself in a Terran ocean!'
@Nead
Sounds hard core SciFi doesn't it? 🙃 🤪
@65dBnoise Space travel is easy. Just follow the blue trajectory road! Duh.
