- 2. Discovery Science • WFIRST was highest ranked large space mission in 2010 Decadal Survey • Use of 2.4m telescope enables - Hubble quality imaging over 100x more sky - Imaging of exoplanets with 10-9 contrast with a coronagraph 2 Dark Energy Exoplanets microlensing coronagraph Astrophysics M63 HST WFIRST
- 5. WFIRST Instruments Wide-Field Instrument (WFI) • Imaging & spectroscopy over 1000s of sq. deg. • Monitoring of SN and microlensing fields • 0.7 – 2.0 micron bandpass • 0.28 deg2 FoV (100x JWST FoV) • 18 H4RG detectors (288 Mpixels) • 6 filter imaging, grism + IFU spectroscopy Coronagraph (CGI) • Imaging of ice & gas giant exoplanets • Imaging of debris disks • 400 – 1000 nm bandpass • ≤10-9 contrast (after post-processing) • 100 milliarcsec inner working angle at 400 nm 5 GEO or L2 orbit Serviceable
- 7. What's Happening with WFIRST 7 • Huge progress on WFIRST this year • $106M in FY14 & 15 has enabled major steps forward • H4RG detector development • Coronagraph development • Design cycles, Project work • SDT 2014 study completed • ROSES community studies • Pasadena conference held • Special session at AAS • ExoPAG, COPAG, PhysPAG • Exciting times for WFIRST coronagraph shaped pupil mask H4RG-10 mounted in EDU structure
