I don't know, we've had two rovers up there for about two years now. This is a huge waste of money. I see a lot of the comments, "cool" "wow", "maybe this will usher in world peace if we all just focus on space". I guess I have to be a little less negative, but am I wrong. But really, we're just going to find dirt/rocks in a 3rd area on mars now. I think since putting people on the moon we've been stuck to justifying "well you'd never have that cool foam memory bed if it wasn't for NASA" because it was after all of those Apollo missions NASA probably said to themselves we need to convince congress to give us more money. And world peace, I'm sure we're working way harder on the militarizing space. My comment depresses me but trillions of dollars later and what, really what has come of it? And only answer that if you have any concept of what a trillion dollars is. millions, billions, trillions are thrown around so flippantly these days. One trillion dollars in 1 Million briefcases of 1Million dollars. Basically a 60,000 sq ft warehouse filled end to end, top to bottom. So, curiosity is on Mars, what does that mean??????? 250+ comments and cool, rad, uber cool, this proves the US is #1 in space again (right). Best part of it all is they've spent our money on it and we'll never know half of what it really does. I'm sure we didn't send it there to see if there used to be an amoeba somewhere on Mars. They should have put a 1k shot/sec paint ball gun on it and go after the other two rovers. I'm over the edge now, sorry people. Sorry NASA people I know you worked hard on this, but in the end this is going to be .5Trillion expenditure. What did the other rovers find that said, ohh we need to send a third. I guess they have to do something to keep the money coming in. Where are all you people who think the moon was a hoax? (I don't believe that was a hoax), but just wondering, this is mathematically probably 1000x harder.
