Of course we want to go to Mars. Until we figure it out though, roving robots with names like Spirit, Opportunity, Sojourner and Curiosity are our best bet for digging up dirt on our nearest planetary neighbor. Want to go along for the ride?
Because an Earth-like environment is created within a spacesuit, it allows you to walk around in space in relative safety. But outer space is an extremely hostile place and could kill you if you aren't protected.
If you spent a year on Mars, you would need to take more food and water than you could possibly carry. But if you had to go, how much would be enough?
Thousands of satellites fly overhead every day, helping us with things like weather forecasts, scientific research, communications, TV broadcasts (and maybe some surreptitious spying). How much do you know about these eyes in the sky?

If you consider throwing down a welcome mat on the porch of the International Space Station the same as living "elsewhere," then yes. But what about the moon and destinations beyond?
Yes, we have some amazing inventions thanks to space exploration, and we're curious about life on other planets. But the cosmos also touches a deeper part of our psyches. Here are 10 reasons space exploration matters to you.
The history of space exploration is full of firsts: first animal in space, first human on the moon, first probe to reach mars. But as they say, you've got to look before you leap. So what was the first telescope launched into space?
Sure, the shuttles may be sitting around in museums now, but our journey to space is far from over. Get ready to meet some serious contenders in the new space race.
