Wellnitz (U.Md), M.J.S. Belton, (Belton Space Initiatives), A. Delamere (Ball Aerospace and Technologies Corp), K.P. Klaasen (JPL), J.Kissel (MPI), K.J. Meech (U.Hawaii), H.J. Melosh (U. Arizona), P.H. Schultz (Brown U.), J.M. Sunshine (SAIC), J. Veverka (Cornell U.), and D.K. Yeomans (JPL) The Deep Impact mission, two spacecraft, a flyby and an impactor, will explore beneath the surface of comet 9P/Tempel 1. The impactor will excavate a crater. Imagers and a spectrometer observe the collision, ejecta curtain and the crater, making a direct comparison of the newly excavated interior to that previously emitted into the comet’s coma. Launching together in January, 2004, for a 1.5 year cruise, encounter and impact will be July, 2005. Twenty-four hours before, the two spacecraft will separate. The flyby spacecraft will be slowed and diverted to miss the comet by 500 km. Closest approach occurs ~14 minute...

Images are typically 5–6km wide with 3-color coverage over the central 20% of the swath, and their scales usually range from 25 to 60cm/pixel. Nine hundred and

Both tubes are 512 channel, parallel-output devices and feature CsTe photocathodes on MgF2 faceplates. Using a computer-assisted test facility, the tubes have been characterized with respect to diode array performance, photocathode response (1100-9000 A), and imaging capability. Data

Late in 2007, the flyby spacecraft was retargeted for a November 4, 2010 encounter with comet 103P/Hartley 2. This extended mission is highly significant for comparative comet studies because it represents the first opportunity to

The NASA Jet Propulsion Laboratory funded a series of industry led studies in 2001 to investigate the alternatives for the MSR mission.
