AkaSci, 1 year ago to random Artemis 1 update 09:00 ET Nov 28. The Artemis Orion spacecraft can now see earth just to the right of the moon. Around 12:40 ET, the moon will have traveled further to the right so that earth will be directly behind the moon as seen from Orion. The first graphic below is a simulated view, based on real telemetry data.
