We celebrated at the observatory with our Artemis II launch party — and NASA delivered a show worth celebrating! The crew has left Earth's inner magnetic field and entered the magnetotail, a comet-like stretch of our planet's magnetic field millions of kilometers long that humans have never visited. The Moon electrifies dust there monthly — and Artemis II is heading right into it. Truly going where no one has gone before! https://spaceweather.com/ #ArtemisII #NASA #MoonMission #LaunchParty
