Marshall Space Flight Center announced the award of six contracts, totaling $1.8 million, for development studies of the interim upper stage (IUS) and space tug. The IUA-A predecessor to the space tug, to be used with the space shuttle by both the Dept. of Defense and NASA until the more sophisticated and capable tug was ready for use in 1983-was being developed as the orbit-to-orbit stage (OOS) by the Air Force.
General Dynamics Corp. Convair Div. was awarded a $290 000 con-tract to study space shuttle and tug compatibility and develop detailed interface requirements. A second contract to General Dynamics, totaling $268 000, was awarded for a definition study of space tug avionics systems with emphasis on areas where transition from the IUS to the tug would require significant hardware or operational changes. United Air-craft Corp. Pratt & Whitney Div. received a $375 371 contract to evaluate and verify the RL-10 high-area-ratio nozzle engine performance for space tug application. Under a $246 000 contract, Martin Marietta Corp. would develop concepts, techniques, and tools for tug fleet and ground operations, mission assignments, payload and orbiter integration, tug scheduling, and physical status. MSFC awarded McDonnell Douglas Corp. a $293 277 contract to study IUS-tug payload requirements compatibility and International Business Machines Corp. a $337 250 contract to study IUS-tug orbital operations.

NASA announced the selection of four U.S. scientists-Dr. David J. Anderson, Kresge Hearing Research Institute at the Univ. of Michigan; Dr. Joseph Bragin, California State Univ.; Dr. John Oro, Univ. of Houston; and Dr. Alfred R. Potvin, Univ. of Texas-for its 1974 life sciences research program. Each scientist would spend a year at a NASA Center studying life sciences related to space exploration. The program had been recommended by the National Academy of Sciences to increase participation in space- and aeronautics-related research by the scientific community. (NASA Release 74-197)
