9496 Ockels           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Wubbo J. Ockels (b. 1946) became the first Dutch astronaut in space during the Spacelab D-1 mission. After his flight aboard the Space Shuttle Challenger in 1985 he continued working for the European Space Agency and became professor of aerospace at the Technical University of Delft. The name was suggested by W. A. Froger.
