NASA announced it had invited scientists to submit proposals for life sciences experiments to be carried aboard the Space Shuttle and Spacelab in the early 1980s. The experiments would study physical effects of spaceflight on humans and other living systems, and would test equipment and procedures. These experiments would be performed in the pressurized cabin of the Space Shuttle orbiter, in a pressurized Spacelab module, or (if requiring continuous exposure to the space environment) attached to an unpressurized Spacelab pallet. Proposed investigations would have to meet one or more of the following life sciences objectives: investigate and understand physiological, performance, and biochemical changes observed in humans who had flown in space; identify and investigate significant biological phenomena that might occur during or after exposure to the space environment; and/or test and demonstrate under operational conditions the equipment and procedures that would be needed by the NASA life sciences program.

DFRC announced it had tested on one of the center's YF-12 aircraft a dual-mode landing-gear system that used variable stiffness landing gear to reduce structural fatigue and dampen vibrations for future large aircraft ground operations. Three different landing-gear configurations tested at various speeds and weights over rough portions of the runways and taxiways resulted from changing loads on both the main and nose landing gear.
