2004-047A
The Swift Gamma Ray Burst Explorer is a MIDEX mission selected mid 1999. PI Gehrels/GSFC. Spectrum Astro SA-200LL bus. (SA-200HP version). Launch by Delta 7320-10 to 600 x 600 km x 20 deg orbit. Control from GSFC via Malindi.
Size is 2.4h 1.7dia 1470 kg. ( 1331 kg as of 2003, 1550 kg max). Deployed 5.6m high 5.4m wide. Irreg cyl + 2 panels
XRT is f=3.5m 0.35m dia, 15" res, 23 arcmin FOV. with one 600 x 600 EPIC-MOS type CCD. Area 110 cm2 at 1.5 keV.
The largest instrument is BAT, a box about 2.5m across 1.5m high. It has a coded mask telescope with a CdZnTe solid state detector. Effective area is 5200 cm2 and FOV is 1.4 sr with 17 arcmin PSF. Swift/BAT will also do a hard x-ray survey.
The UVOT optics were built from XMM/OM flight spares.
