78578 Donpettit           Discovered 2002 Sept. 14 by R. Matson on NEAT images taken at Palomar.
Donald R. Pettit (b. 1955) flew on STS-113 to the International Space Station, where he spent over 5{1\over2} months as science officer on Expedition 6. An avid amateur astronomer, Pettit recorded dozens of astrophotographs from ISS, most notably numerous 30-second and 60-second exposures of (4) Vesta.
