The HMC Physics Clinic team is working on the Space Inteferometry Mission. SIM is an orbiting inteferometer 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.
