Finding exo-Earths: The Synergy of Direct Imaging and Astrometry 03.31.10
Finding exo-Earths: The Synergy of Direct Imaging and Astrometry Three members of the SIM Science Office, Michael Shao, Joseph Catanzarite, and Xiaopei Pan have submitted a research paper titled The Synergy of Direct Imaging and Astrometry for Orbit Determination of exo-Earths to the Astrophysical Journal and posted a preprint at arXiv.org, http://arxiv.org/abs/1003.4702. In the article the authors address the question: "Can a prior astrometric mission that can identify which stars have Earthlike planets significantly improve the science yield of a mission to image exo-Earths?" They find a large increase in the efficiency of direct imaging missions when astrometric data are available for a target star.

The Kepler connection 03.31.09
The Kepler connection The Kepler mission, launched on March 6, 2009, is the first step in NASA's quest for finding Earth-like planets with space-based telescopes. Kepler will monitor 100,000 stars for the telltale dimming that will occur when an Earth-like planet passes in front of its parent star and blocks out a small portion of its star's light.
