42998 Malinafrank           Discovered 1999 Oct. 17 by P. Pravec and P. Kušnirák at Ondřejov.
American aeronautical engineer and painter Frank Joseph Malina, Jr., (1912-1981) was a pioneer in scientific engineering, particularly rocket propulsion. He served as acting director of the Jet Propulsion Laboratory from its founding in 1944 to 1946. In 1947 he joined UNESCO and after 1953 pursued his interest in kinetic art.
