The Challenge of Pointing Stability and Accuracy in the Space Interferometer Mission (SIM)

SIM is an orbiting interferometer telescope capable of relative star measurements 100 times more accurate than ever before. Specifically, the team is devising a technique for measuring the spacing between telescopes, measuring changes in distance to an accuracy of 100 picometers, or 1 angstrom, roughly the size of a hydrogen atom.
