Countdown To NASA's Kepler Mission
Adam Korbitz writes "NASA's planet-hunting Kepler mission is set to launch late on the evening of March 6th. A few days ago, the space telescope arrived in Florida for final launch preparations. According to the NASA/JPL Planet Quest website: 'Kepler will hunt for planets using a specialized one-meter diameter telescope called a photometer to measure the small changes in brightness caused by the transits. Over a four-year period, Kepler will continuously view an amount of sky about equal to the size of a human hand held at arm's length or about equal in area to two "scoops" of the sky made with the Big Dipper constellation.' A map of the area Kepler will search is shown superimposed on a picture of the constellation Cygnus, The Swan. NASA has posted a countdown clock for Kepler, as well as animations of the spacecraft mission and the science objectives."
How cool. They matched the CCD arrangment in order to macth the most effective pattern of target stars for corevage and efficientcy:
from the article: "The squares show the FOV of each of the 21 CCD modules. Each is 5 sq deg. Note that the gaps between the CCD modules are aligned so that about half of the 15 stars in the FOV brighter than mv=6 fall in these gaps."
