NASA's Kepler Telescope Launched Successfully

Iddo Genuth writes "At precisely 10:49 p.m. EST, NASA's 'Kepler' telescope was successfully kicked off into space, embarking on a mission that the agency says 'may fundamentally change humanity's view of itself.' The telescope will search the nearby region of our galaxy for the first time looking for Earth-size planets, which orbit stars at distances where temperatures permit liquid water to endure on their surface — a region often referred to as the 'habitable' zone."

Not only has it launched...

...but it's generating it's own power and is communicating. From http://www.nasa.gov/home/hqnews/2009/mar/HQ_09-052_Kepler_launches.html

Engineers acquired a signal from Kepler at 12:11 a.m. Saturday, after it separated from its spent third-stage rocket and entered its final sun-centered orbit, trailing 950 miles behind Earth. The spacecraft is generating its own power from its solar panels.

I've always wanted to travel to other worlds.

It's an appealing thought. But is also works in reverse.

Do we really want the other worlds' explorers coming here? Let's see what we humans have done to new lands: genocide, penal colony, battleground, food resource, or tourist trap. I vote we use Kepler to watch out for the scumballs, so we can prepare to zap them before they arrive.

obvious but worth saying

I know this is obvious to most people but the "habitable zone" is awfully generous. It's hard to gauge the exact amount of heat given off by a star from as far away as we are. Plus, the atmosphere content is extremely important. Our moon is basically the same distance away from the sun as us and with no atmosphere it goes from like -180 to +200 F or something like that. So yeah, it kinda needs to have an exact amount of certain gases to keep water from boiling and freezing repeatedly, which would probably kill everything organic in it. And how are be supposed to tell if it's 40% as opposed to 50% CO2 in the atmosphere from all the way out here? It's impossible and that could mean a huuuuge temperature difference. So even if they find one that's supposedly perfect from what we can detect, it's still extremely likely that it's not.
