Deranged Rhino Posted March 21, 2014 Posted March 21, 2014 A NASA scientist brazenly announced the urgent need for mankind to terriform not one, not two, but three planets ... just to keep our species alive. Or, you know, if that fails we could try something else like salt water farming. http://motherboard.vice.com/read/we-need-three-planets-to-keep-the-human-race-alive-nasa-scientist-says

Earth's rotating molten metal core is what generates the electromagnetic field that shields our atmosphere from the solar winds. Mars being smaller than Earth cooled down quicker and lost it's molten core a billion years ago. Carl Sagen hypothesized that Mars could be terraformed with plants. But without a EM field around the planet whatever gases you could generate would drift off into space. You might as well just live on the moon. PTR

PTR No, without a magnetic field you're exposed to solar radiation. That has ****-all to do with keeping an atmosphere. It's also one of the biggest technical hurdles for a manned Mars mission, as you need something to protect people from solar flares, both in transit and on the Martian surface.

Given the gases released, I think these should more accurately be called "Sun farts"
Nanker Posted March 22, 2014 Posted March 22, 2014 Right. We don't have a rocket ship capable of reaching the ISS, yet alone the moon, and this buzzard wants to go to the planets.

But I have it on good authority (from the History Channel) that we have a secret space military program that is capable of reaching across the universe -- let alone upper orbit -- in a matter of moments. They wouldn't lie about something like that on the History channel, would they?
