In this week's questions show, I explain why I don't think we always need to be realistic, if galaxies in the local group are bound together gravitationally, and what we should call Earth-moving equipment on Mars.
00:20 Be realistic.
04:24 Are galaxies in the local group bound?
05:56 Will gravitational waves give us advanced notice of collisions?
08:36 Will we ever be able to live outside on Mars?
10:16 Are we going to ruin Mars too?
12:42 Mars-moving equipment?
14:07 Could the Moon have an atmosphere?
15:51 Liquid water on the surface of Mars
16:49 Is there a business case for Mars?
19:17 What about nitrogen?
21:21 What will need to come from Earth?
23:06 Are there planets with less gravity than Earth?

I’m curious. Does this Curiosity update satiate my curiosity?
I’ve never yet seen a UT article with absolutely no text… Thanks for the post, but what’s up?
the tire tread looks far from adequate, it looks like its begging to get stuck, im not expert but i have quite a few years as a kid racing remote control monster trucks and, considering the cost and effort they are making to get this thing from not smashing into smitherines after entry. im suprised at what im looking at. i know the gravity is approximatly 1/3 earths the speed could surely be increased and ability to get unstuck improved had they put better wheels on that thing. . . . .
The depth of tread seems ridiculously small. I would have expected something much more aggressive, especially as they are expecting to run on sand all the time. Any RCer will tell you that you want sand paddles. However, I would also expect that NASA and the MSL guys will have tested all types of tyres, and chosen then best overall compromise.
