NASA's Kepler probe is on schedule to begin its mission. The protective covering over the lens of the photometer that will be used to look for transits of planets across the disk of their parent star was successfully jettisoned earlier this week.
The next few weeks will be spent calibrating the instrument. Detecting a transiting planet by noting the tiny dip in light coming from a star is a demanding task, so having the photometer in top operating order is essential.
When the callibration is complete, the real fun will begin.
