10972 Merbold           Discovered 1973 Sept. 29 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
In 1983 and 1988, the German physicist Ulf Merbold was the first European astronaut to perform research on board the Space Shuttle with the European Space Agency's Spacelab. This was followed in 1994 by four weeks as an ESA astronaut on the Russian Mir Space Station. The name was suggested by H. Graf.
