Astronomers are hoping for a spectacular high-impact collision as asteroid 2007 WD5 zooms toward Mars
Can everyone be an astronomer? It certainly seems that way, especially with some of the latest tools at our fingertips, like Google Sky, which allows Internet users to navigate through a digitized map of space. But some say virtual astronomy is not just for amateurs and should also be the way forward for professional space exploration. A future of virtual astronauts, too.
The soil on Mars may contain microbial life, according to a new interpretation of data first collected more than 30 years ago.
When, after an eight-month voyage, NASA's Mariner 4 spacecraft beamed back the first images of Mars in 1965 -- to score a victory over Russia's Mars 1 in the Cold War space-race -- it changed the way scientists thought about the Red Planet.
Spectacular new images of Mars could reveal clues about tens of millions of years of the red planet's history.
Nearly three years after landing on Mars, the rover "Opportunity" has reached a region of the planet that may provide the best clues yet about the history of the red planet.

NASA started it all back in 1976 with an image of an interesting mountain on Mars and a caption that described it as appearing to have eyes and nostrils.

Attention, people of Earth: We are going to Mars. This is no sci-fi fantasy; for the past two years, NASA has been gearing up to meet the Bush administration's goal of landing humans on Mars by around 2030. The agency plans to set up a base on the Moon by 2020 to act as a staging area; that effort alone is projected to cost at least $104 billion. Throw in the round-trip voyage to Mars, and John Edwards, space systems analyst at Forecast International, estimates that the total cost of the program will top $400 billion--making it history's largest government-backed science project.
