Proposal Title: Radar Observations of Comet 103P/Hartley 2
ABSTRACT:
We propose to make S­band radar observations of Comet 103P/Hartley 2 during its close Earth passage in
October­November 2010. The objectives will be to estimate the nucleus properties (size, shape, spin, surface
density) and to search for, and characterize, any population of large (>cm­size) ejected grains. The radar results
are expected to complement and support the EPOXI spacecraft mission flyby in November and should enhance the
overall scientific return from the Hartley 2 apparition.
