Paper Abstract

SIM, a micro-arcsecond astrometry space mission, has been impacted by significant changes in NASA priorities over the last two years, resulting in the mission being indefinitely delayed. The project team has responded by investigating alternative mission concepts based upon completed SIM technology. Several alternative mission concepts have been identified, ranging from a planets-only concept, to versions of SIM, called SIM-Lite, that still address the full breadth of science envisioned by two previous National Academy Astrophysics Decadal Surveys but with lower precision and reduced throughput. These mission concepts are significantly more affordable and may fit into a nearer-term future scenario than the full SIM PlanetQuest17 would. This paper describes the current state of the project, including its design and technology, and the alternative mission concepts for the use of these designs and technology.
