After a rocket body impacted the Moon last year, NASA's Lunar Reconnaissance Orbiter was able to snap a surprising view of the impact site. Unexpectedly, the crater is actually two craters and may indicate that the rocket body had large masses at each end: go.nasa.gov/3byMaTS

We want to put @NASA_Orion through its paces on #Artemis I to ensure we're ready for crewed missions starting on Artemis II. Flying to the Distant Retrograde Orbit will add rigor to the mission, allowing us to assess the spacecraft's performance. More: go.nasa.gov/3Aaf9rd

This week, NASA's GEODES team is at Lava Beds National Monument testing tools and methods for exploring what's beneath the surface of the Moon! Follow along with them all week on @NASAExpeditions.
Lava Beds National Monument is full of lava tubes – caves formed from molten lava. And that’s why we’re here. Lava tubes can also be found on the Moon! This image from NASA's Lunar Reconnaissance Orbiter shows the opening of a lava tube on the Moon.

Upper stage liquid hydrogen is now full. The team is still troubleshooting the leak at the core stage quick disconnect. Team is working to manually adjust the LOX pressure in upper stage to get back into tanking. Plan for small fire at pad is to allow it to burn out.
