Unbelievable. We have personal iPhone footage from an astronaut going around the far side of the Moon capturing the Earth setting behind it.
Reid Wiseman@astro_reid
Only one chance in this lifetime… Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him. I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

The Artemis 2 crew, returning from a lunar flyby, is doing something they've never done with people on board.
Orion is flying at 40,000 km/h. At that speed, the atmosphere isn't air, it's a wall. You can't just dive down—the crew would be crushed by the G-forces, and the ship would burn up.
So they came up with this idea. Orion will enter the atmosphere, heat up to 2800 degrees, and bounce back into space. Like a pebble bounces off water. Remember throwing flat stones down a river as a kid?
Up there, it has a couple of minutes to cool down. Then it reenters and lands.
The trick is that such a jump drops the G-forces from 10g to 4g. The difference between tolerable and done.
The Apollo missions returned differently. They didn't jump, they simply glided through the upper atmosphere like a skier down a hill, gradually losing speed. One pass and that's it. It worked, but the G-forces were severe.
The Soyuz reenters the ISS quite simply. Its speed is half that of Orion, and the atmosphere handles it in one pass. No tricks needed.
But Orion arrives from the Moon. Different speed, different task. That's why they came up with this jump.
But if the calculations are off even slightly, the rebound will throw the ship back into orbit, into space. There are no braking engines left. They'll simply wait for the Earth to pull them in. With a finite supply of oxygen. And if the rebound is even higher, they'll be blown off into space altogether.
I hope everything goes perfectly...

Keep an ear out for a sonic boom this Friday afternoon! 🚀 NASA says the Orion capsule carrying the Artemis II crew will re-enter the atmosphere around 4:54 p.m., wrapping up its historic trip around the moon. It’s scheduled to splash down in the ocean about 50 miles west of San Diego right at 5:07 p.m. 🌊💥

🚨: CONFIRMED SEPARATION!
The powerful Orion spacecraft of the Artemis II mission has been precisely released from the SLS upper stage, paving its way toward its historic rendezvous with the Moon.
Tomorrow, humanity will take a giant leap: Orion will perform the first crewed lunar flyby in over half a century.
The era of returning to the Moon has begun!
