Nasa Launches Search For Second Earth

[ALien]

The US space agency's first mission to look for habitable, Earth-sized planets has begun

The launch of the Kepler spacecraft from Cape Canaveral in Florida today marks the beginning of the most ambitious hunt for planets like ours in distant solar systems.

The Kepler telescope will spend three-and-a-half years staring deep into a starry region of the Milky Way, in the direction of the constellations Cygnus and Lyra, in the hope of spotting Earth-sized planets as they pass in front of their stars.

Every half hour, Kepler will record the brightness of 100,000 stars using a 95 megapixel camera built by the British firm e2v. The camera is so sensitive, it could spot the imperceptible dimming of a car headlight as a fly wanders across it.

The mission will focus its attention on planets in the "Goldilocks region" of space, where conditions are just right for liquid water to exist. Some of these worlds could potentially be home to life as we know it.

By the end of the mission, we may have a clearer idea of our place in the universe, and whether warm, wet rocks like Earth are the exception rather than the rule.

They say it will take a while, but the space telescope will do the same type of job they did on Earth. This will be better because there is no interference from the atmosphere.

What an incredible waste of tax dollars given the current economic climate.

Actually, the money was spent for this project way before the meltdown. NASA and other agencies get their monies way in advance for these types of projects because of the time it takes to build and program them. They may have had the money a decade in advance. Also, this does help the economy by employing people to build the craft and maintain it.
