NASA announced the completion of the preliminary flight rating test of the Nation's first liquid-hydrogen rocket engine. The engine, the RL-10, was designed and developed by Pratt and Whitney, of United Aircraft, for the Marshall Space Flight Center, and 20 captive firings were completed within 5 days under simulated space conditions, consistently producing 15,000 pounds of thrust. RL-10, previously known as XLR-115, was initiated in October 1958 and over 700 firings were conducted in its development.
Navy Skylark balloon began coast-to-coast flight carrying University of Chicago cosmic ray experiment, launched at Brawley, Calif., and landing near Asheville, N.C., on November 21.
