NASA signed an agreement to support the University Corporation for Atmospheric Research (UCAR) study of the feasibility of using the Shuttle's external tanks as research, storage, or manufacturing facilities. Space Shuttle fuel tanks were used to carry 500,000 gallons of liquid hydrogen and oxygen for launch and initial insertion into orbit. The agreement followed a June 1988 NASA announcement requesting commercial and academic uses for expended tanks. (NASA Release 90-26)
A German scientific satellite, ROSAT, scheduled for NASA launch on a Delta II rocket, in early summer, arrived at Cape Canaveral, Florida, on this date from the Federal Republic of Germany aboard a 747 cargo plane. The spacecraft was to perform "all sky" surveys with two x-ray imaging telescopes, after which it would focus on detailed x-ray sources. (NASA Release 90-27)
