Kepler Mission Manager Report - Mar. 12, 2009
Kepler's science instrument, called a photometer, was powered on by flight controllers and will be calibrated over the following several weeks. A dust cover continues to be closed over the front of the photometer so that Kepler's first images will be dark. The dark images help engineers distinguished the noise in the instrument's electronic devices. The spacecraft's powerful Ka-band radio transmitter was powered on and the vehicle was steered to point its high-gain antenna towards Earth for testing. The main set of response control thrusters was fired for the first time to zero out the small amount of angular momentum that, due to pressure from the sunlight 's intense light, has developed in Kepler's reaction wheels.
