"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," he wrote on X.
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… pic.twitter.com/8aWnaFJ69c

This was the first time that human eyes had witnessed an Earthset in 54 years since the Apollo 17 mission. The Artemis II crew flew more than 5,000 mil
