Let's step into the light and explore the terminator. It's the line between day and night. As the NASA Artemis II crew flew over the Moon's terminator, they saw lunar craters and ridges cast dramatic shadows, the kind future explorers might see at the Moon's South Pole.

The Artemis II Preliminary Science Report dropped last week, with hundreds of gigabytes of crew observations. From shadows at the edge of the terminator to a solar eclipse from the far side of the Moon, the science report is full of details to explore.

the way the terminator turns craters into long shadows makes the south pole sound like a completely different moon

@NASAMoonBase I freaking love your shirt!!!

@NASAMoonBase If you’re going to do more of these, try to avoid vocal fry.

Great job NASA girl, keep telling the world about lights and terminators and Moons. Fan-fucking-tastic!

And the rest??
