Kepler

Launch: March 6, 2009
The Kepler Mission will search for Earth-like planets with the "transit" method. A one-meter diameter (39-inch) telescope equipped with the equivalent of 42 high quality digital cameras will continuously monitor the brightness of 100,000 stars, looking for planets that cross the lines-of-sight between Kepler and their parent stars.

The European Space Agency's Rosetta spacecraft will rendezvous with comet 67P/Churyumov-Gerasimenko in 2014. While Rosetta orbits the comet, JPL's Microwave Instrument onboard the spacecraft will study gases given off by the comet. In addition, a package of instruments will set down and study the surface of the comet.

Moon Mineralogy Mapper

Launch: Oct. 22, 2008
The JPL-managed Moon Mineralogy Mapper is one of two instruments that NASA is contributing to India's first mission to the moon. The instrument is a state-of-the-art high spectral resolution imaging spectrometer that will characterize and map the mineral composition of the moon. The Moon Mineralogy Mapper is aboard Chandrayaan-1.

Palomar Observatory

First light: December 1998
A joint effort between JPL and the California Institute of Technology, the Palomar Observatory near San Diego houses a collection of famous telescopes, including the Hale 200-inch and Samuel Oschin 48-inch telescopes. The Palomar Adaptive Optics System, built by JPL and Caltech, corrects for the atmospheric blur of astronomical targets caused by turbulence in Earth's atmosphere. This system's camera was built by Cornell University, Ithaca, N.Y.
