The Artemis II astronauts had the rare opportunity to witness a solar eclipse from the perspective of the Orion spacecraft whizzing them through space during a historic flyby over the moon.
Observing the celestial phenomenon was not originally part of the plan for when the crew of NASA's first human moon mission in more than 50 years soared over the lunar surface. But the space agency ultimately made the call to add that to the agenda a few days before astronauts Reid Wiseman, Christina Koch and Victor Glover of NASA, as well as Jeremy Hansen of the Canadian Space Agency, neared the moon.
Toward the end of an observation period Monday, April 6, the four astronauts donned protective glasses and observed what had to be a breathtaking sight as, from their vantage, the moon blocked the sun and most of the light it emits.
Here's what to know about the solar eclipse the Artemis II astronauts experienced.
