The Kepler Mission consists of a 1-meter Schmidt telescope in an Earth-trailing orbit designed to detect transiting planets in a field of 100 square degrees in the Cygnus-Lyra region, with an input Catalog of over 100,000 stars of V magnitude mostly 12 to 15. Doppler measurements are useful for verifying the planets and measuring their masses and orbits including eccentricity. The Kepler follow-up team is using the Keck telescope and HIRES spectrometer to make Doppler measurements with a precision of 3 m/s, a challenging goal for 13th mag stars. Novel Doppler techniques are being developed. The Doppler observations have helped confirm the discovery of exoplanets with sizes ranging from 0.6 Rj to1.5Rj with orbital periods of 3 to 9 days. Kepler was selected as the 10th mission of the Discovery Program. Funding for this mission is provided by NASA, Science Mission Directorate. Access to the Keck telescope was provided by NASA and by the University of California.
