Welcome back to Season 2 of my weekly live QA. Your chance to ask me your questions about space and astronomy... live. Sometimes I'll have guests, and sometimes I won't. This week... I didn't.
You wanted to know about recent news about astronauts mixing concrete in space, the formation of craters on Titan, and what might be the difficulties of people going to the Moon or Mars?
