Simulations demonstrate SIM's planet-finding capabilities
Detailed simulations of SIM's planet finding capabilities have been published in PASP. (Read more)

May 2005: A Mission for Astrophysics and Planet-Finding
Whitepaper available: "SIM PlanetQuest: A Mission for Astrophysics and Planet-Finding," by Stephen J. Edberg, Michael Shao, and Charles A. Beichman (Read more)

October 2004: Race to the impossible: SIM's amazing technology breakthroughs
The Decadal Survey for Astronomy and Astronomy and Astrophysics of the 1990s set forth a lofty goal: develop a revolutionary space telescope that would "... achieve a 1,000-fold improvement in our ability to measure celestial positions." This new instrument would enable scientists to rigorously test accepted astrophysics theories, resolve fundamental questions about our galaxy, and detect Earth-size planets around other stars, among many other science objectives.

June 2003: SIM receives go-ahead to enter Phase B
The SIM Project has just successfully passed its most important milestone to date, on its path to launch in 2010. By authorizing SIM to enter Phase B, NASA reaffirms its commitment to to this mission, and the revolutionary science results that it is expected to provide. (Read more)

November 2002: SIM completes final Phase-A technology milestone
The SIM team completed the last of the Phase A milestones on October 29, 2002. This milestone demonstrates both wide-angle (global astrometry) and narrow-angle 'basic' performance of the external metrology system needed to relate SIM's guide interferometers to the science interferometers at the 10's of picometer level. This result comes from the 'Kite' Testbed - a combination of 6 laser metrology gauges arranged in a planar layout similar to the shape of a child's classic four pointed kite. (Read more)
