Me just waiting for it to blast off. This is gonna be a heck of a mission. Kepler would primarily look for planetary systems around other stars and hopefully detect Earth sized planets. After HST this is gonna be the next best WOW mission from NASA. Not that NASAs other missions are dud but then me just waiting for this to happen

Over its three and a half year mission, Kepler will attempt to detect planets 30 to 600 times smaller than Jupiter. Given that Earth-sized worlds do exist around stars like the sun, Kepler is expected to be the first to find them, and the first to measure their frequency. Locating rocky worlds like Earth, including those that lie in a star's habitable zone, could mean identifying planets where liquid water, and perhaps life, could exist.

To measure the light curves of hundreds of thousands of stars continuously at the same time for the next 3-4 years using a wide-field camera pointed at a specific spot in the sky. (The field of view is around 100,000 times that for the HST - besides HST can only look at a fixed spot for 30 mins at a time.)

There is a small probability that the fluctuating light curve for a star which is a "twin" of our sun will have three cycles in three years suggesting an earth-like planet in an earth-like orbit about it - with a possibility of earth like conditions like liquid water!

Kepler is a critical component in NASA's broader efforts to ultimately find and study planets where Earth-like conditions may be present. The planetary census Kepler takes will be very important for understanding the frequency of Earth-size planets in our galaxy and planning future missions that directly detect and characterize such worlds around nearby stars. The mission will spend three-and-a-half years surveying more than 100,000 sun-like stars in the Cygnus-Lyra region of our Milky Way galaxy. It is expected to find hundreds of planets the size of Earth and larger at various distances from their stars. (Source : Google).
