Abstract:
The Wide Field InfRared Survey Telescope mission is the highest
priority large space project recommended by the 2010 Astronomy and
Astrophysics Decadal Survey, and it is expected to begin development in
2017 when the James Webb Space Telescope is nearing launch. WFIRST was
conceived to conduct wide field, near-infrared surveys for dark energy,
exoplanet gravitational microlensing, and general astrophysics using a
moderate aperture (~1.3-m) telescope. NASA has recently approved the use
of a much larger, Hubble-sized (2.4-m) telescope that was donated by
the National Reconnaissance Office. A science definition team is now
studying a revamped WFIRST mission concept with this telescope,
including a coronagraphic instrument for exoplanet and disk imaging and
spectroscopy. This talk will highlight the mission's science potential
including brief descriptions of its dark energy and general observer
programs with more focus on its exoplanet microlensing survey and
coronagraphic imaging and spectroscopy of nearby exoplanetary systems.
