The upper stage of a commercial Atlas rocket made by General Dynamics Corporation carrying a satellite for the Japan Broadcasting Corporation failed after liftoff from Cape Canaveral. Ron Maehl of General Electric Aerospace Group, which made the satellite, refused to state the cost for the spacecraft and the launch, saying only that the rocket cost slightly more than the satellite. The accident was described as a major setback for General Dynamics whose Atlas program lost $300 million in 1990. Details of the stages of the Atlas-Centaur rocket and its intended use to replace the satellite destroyed in the explosion of a European Ariane rocket in February 1990 were given.

NASA announced crew assignments for the International Microgravity flight, scheduled for February 1992 and the Spacelab D-2 mission, the second German Spacelab flight, scheduled for February 1993. Lt. Col. David C. Hilmers was to be mission specialist on the microgravity flight and Lt. Col. Jerry L. Ross was to serve as Payload Commander on the Spacelab flight. (NASA Release 91-57)
NASA solicited proposals for establishing additional Centers for the Commercial Development of Space (CCDS). These centers were to specialize in the commercialization of advanced satellite communications technologies and other space-based telecommunications technologies. NASA's current CCDS specialize as follows: materials processing, 5; life sciences, 3; remote sensing, 2; automation and robotics, 2; space propulsion, 1; space structures and materials, 1; and space power, 2.

NASA announced that it was conducting intensive analysis of the problem that prevented deployment of the Galileo spacecraft's high-gain antenna. Even if the antenna is only partially deployed, the planned flyby of the asteroid Gaspra on October 29 would take place. (NASA Release 91-59)
The subcommittee of NASA's Office of Astronautics and Exploration Technology said the redesign of the Space Station would still enable all proposed experiments to be handled. However, two major experiments might not be able to be conducted simultaneously because of power limitations. (Htsvl Tms, Apr 19/91)
