Just took this scenario for a spin, and here is a little preview of the lunar flyby:




For the first time humans will see, in-situ, Mare Moscoviense in all its glory... and that will probably be it for lunar features.
Thanks for the scenario @Ajaja !

I hate how it's so American centric. This mission should be for the whole world.

Is it?
Isn't there quite a bit of a collaboration with ESA and Canada?

and another one: long exposure night view!

North and Europe at the bottom left, Africa and the Atlantic on the center, South America on the right.
The bright star might actually be a planet...

Orbiter and the @Ajaja scenario say it is Venus!

Hi there,
as I'm not so familiar with the Artemis acronymns (yet, compared to previous launch systems),
can anyone tell me what "AMT" means?

From a lauch timeline "transcription":

00:18 Integrity, good roll pitch.​

00:21 Roger, roll pitch.​

00:26 Houston, now controlling the flight of Integrity on the Artemis II mission around the boat.​

00:34 Integrity, AMT high.​

00:37 AMT high.​

00:39 On time passing 30 seconds.​

...​

Thanks in advance

I think it is "Abort MECO Target".
There is a paper on SLS aborts from some years ago... but I don't have time to find it right now...

 

[kuddel]

Thanks for the nudge into the right direction!
I found it here: https://ntrs.nasa.gov/api/citations/20205001579/downloads/SLS Engine Out.pdf

Alternate MECO Target

Two other targets, an Alternate MECO Target (AMT) High for engine failures in the middle
portion of flight, and an AMT Low target for failures very early in flight rounds out the engine out
capability of SLS.

Did a comparison of that recent earth shot (the overexposed one) with Orbiter and Space Engine, to identify stars/planets. Of course, I knew that was Venus. But just FYI from the perspective of Orion, the earth at that moment was eclipsing the Constellations Aquarius, Pegasus, and Cetus. The reason the lower left quadrant seems missing is, I believe that's the window edge of the Orion.

Excellent comparison! How did you do this in SpaceEngine? I wasn't able to find a way to set precise spaceship coordinates and velocity vectors for a given moment.

I didn't use spacecraft mode, I used planetarium mode and just manually moved the camera around LOL

Very nice eye balling tbh

This one is such a great shot :

I used to work as a planetarium lecturer for over 5 years. I know my way around space LOL
