For those of you that have lost faith in our space program.

NASA gives all-clear for SpaceX launch April 30.

First commercial resupply of the international space station.
The private sector is now picking up speed to replace a lot of things NASA did.

can't pick my favorite nasa thread today

Mods can feel free to merge if they wish, I just felt like starting a new thread because it's two different subjects we posted about.

Virgin Galactics website.
Lots of exciting stuff in there.

Well if theres any incentive to get the space program moving again its the asteroid headed for Earth in 2029 and then again in 2036 though the 2029 encounter is thought to pose a greater, albeit small, risk at this point. Apparently they would be able to alter it's trajectory by getting a probe to fly with it at a certain point allowing it to miss. I think if I heard right it'll be hard to miss when it hopefully just flies by.

You know I was also thinking about how if we want to continue surviving as a race we'll have to eventually leave Earth but it's not as simple as finding a planet with a similar atmosphere to Earth as well as water. I mean they've found other planets in the habital zone of other solar systems that probably have oxygen and liquid water but they're all different sizes which means less and more gravity then that of Earth.

Mars for example, even if we could start settlements there only has 38% the gravity of Earth. Astronomers have found a couple dozen Earth like planets but some of them like Gliese 581 d are approximately 5.6 times the size of Earth which means gravity wise....well I've heard numbers ranging from 1.1-1.7 that of Earths surface gravity to 4 times that of Earths gravity.

living on mars would be completely doable, it's just that the bones density of people that live there and don't excerise quite a bit would have a very hard time coming back to earth and getting on with things.

IWhat about those of us who never had faith in the space program.

This asteroid is called Apophis and it was discovered back in 2004. A good video of Neil DeGrasse Tyson talking about this in a speech sometime in 2008. Like most idiots, they generally don't care about their survival until it's on the brink of ending.
