What Is WFC3?
• WFC3 is a facility instrument being developed on behalf of HST
user community
–
–
–
–
Will replace WFPC2 in Hubble in early 2004
Assures continued world class HST imaging science to end of mission
International Scientific Oversight Committee (SOC)
Integrated Product Team: GSFC, STScI, Ball Aerospace, Swales, etc.
• Ed Cheng (GSFC) Instrument Scientist
• John MacKenty (STScI) Deputy Instrument Scientist
• WFC3 will be the first “panchromatic” camera on HST.
– Two channels cover Near-UV to Near-IR without cryogen
– UVIS CCD channel backs up ACS while providing unique NUV science
• Wide field imaging from 200 to 1000 nm
– NIR HgCdTe channel improves greatly upon NICMOS
