Kepler Missions & Center Operational

Overview:

The Kepler satellite, launched on 06 March 2009, is a NASA mission that uses high-precision photometry to search for transiting exoplanets around main sequence stars. Kepler is NASA's first mission capable of detecting earth-like planets and its primary mission is to determine the frequency of earth-sized planets around other stars.

In May 2009, Kepler began its survey of 170,000 stars for earth-sized planets; the photometric transit survey has a nominal mission lifetime of 3.5 years with a possible extension for another 2 years.

The scientific objective of the Kepler Mission is to explore the structure and diversity of planetary systems. This is achieved by surveying a large sample of stars to:

  1. Determine the abundance of terrestrial and larger planets in or near the habitable zone of a wide variety of stars;
  2. Determine the distribution of sizes and shapes of the orbits of these planets;
  3. Estimate how many planets there are in multiple-star systems;
  4. Determine the variety of orbit sizes and planet reflectivities, sizes, masses and densities of short-period giant planets;
  5. Identify additional members of each discovered planetary system using other techniques; and
  6. Determine the properties of those stars that harbor planetary systems.

IPAC's role:

Within IPAC, NExScI developed, hosts and operates the Kepler Science Analysis System (KSAS) - the software system used by the Kepler Science Team to collect all mission and follow-up data on planet candidates, manage the follow-up observing and produce mission results catalogs.

The NASA Exoplanet Archive at IPAC  provides access to a Kepler Target Selection Catalog for users to prepare an observing target list suitable for the Kepler Guest Observer Program, and a periodogram service for public Kepler light curves.
