Episode 588: Open Space 51: Where Would I Send A Rover? And More...

It was another solo live QA this week and I did my best to answer as many audience questions as I could do, closing in on 60 questions during the hour. Needless to say it was a wide-ranging conversation with questions about where I think rovers should go, what do I think about time travel, and whether we should do more SETI or build more space telescopes. The thumbnail is for a Greenland rover called Grover.
