Walkabout the Galaxy

Nov 23, 2022

Artemis 1, the most powerful rocket to ever leave the Earth, is up and on its way to the Moon after more hydrogen leaks than we care to remember, and Up Astroquark Dr. Hannah Sargeant signs off on her last Walkabout appearance as she is away to new adventures. We review the Artemis 1 mission, a new tracer for the origin of water on Earth and Mars, and we learn about a new idea for that famous dimming of the supergiant star Betelgeuse. Learn about gravity darkening, also a great name for a rock band, space junk trivia, and more with Strange, Charm, and Up.
