There are "look backs" during certain times, when the astronauts are sleeping for one:
24/7 Live Coverage Continues - The Orion is on a high orbit around Earth after a series of burns. After a few hours of sleep a "Perigee Raise Burn(PBR)" took place, 8:15 am EST, putting Orion on an even higher orbit for a Trans Lunar Injection(TLI) burn tonight at
7:50 pm EST, if all goes well, that will send them on a course to the moon. The SLS is completely autonomous. The spacecraft's Guidance Navigation and Control Systems completed "star field maneuvers" so it knows where it is and where it is going before that PRB burn, amazing!
"star field maneuvers": The way a spacecraft orients itself using stellar tracking cameras to determine its orientation (attitude) while navigating through space
The astronauts are taking a nap
EDIT: They are up getting ready for their busy day. Communications have begun checking all systems, life support etc before heading to the moon

This makes me like - stupid excited. I am continuously watching it. I just can't believe that we have this technology. From me being a kid with no cell phone, my computer, party land line - to now - this advancement. who'd a thunk it that we came this far? wow
In 2017 when Artimus program started some of the technology hadn't been developed yet. It had to be developed. The Apollo computers were a 16 bit system with 4kb of ram yet successfully guided astronauts to the moon. The shuttle program used 5 main computers, 16 bits with 32 bit registers. The Artemis program uses 2 vehicle management computers and 6 power and data units. They are 20,000 times faster and have 128,000 times more memory then the Apollo computers had
