Weekly Space Hangout – Mar. 1, 2012

Another week, another space roundup. This week we talk about the redefinition of the term “Earthlike”, salty soil on Mars, how you can participate in SETI, asteroid dust from Hayabusa, and the dangers of a warp drive.

Just a warning, we somehow lost the first 10 minutes or so of the video, so you’ll have to imagine Ian’s awesome description of the scientists concerned with the definition “Earthlike”, and how that might be changed. We didn’t miss too much of the conversation, though.

Remember, we record this show live every Thursday at 10:00am PST / 1:00 pm EST / 1800 UTC. Join us at Cosmoquest Hangouts, or watch Fraser’s Google+ stream for the show to start.
