Rose out of tower rapidly and tipped, passing over observation shelter; distance 204.5 ft; speed about 60 mph. This flight was followed by a series of static tests, to develop liquid 'curtain cooling' for inside of combustion-chamber wall, a regenerative system, and better stability in flight.

Successful firing of a solid-propellant rocket motor using "building block" method was announced by NASA. References: 17 .
Development time schedule for Dyna-Soar was reduced when DOD authorized the USAF to move directly from B-52 drop tests to unmanned and then manned orbital flights. This eliminated the previous interim stage of suborbital flights to be powered by the Titan II. This required renegotiation of the development contract held by the Martin Co. and negotiating of a new contract for a larger booster. References: 18 .
MSFC Director Wernher von Braun described to Apollo Spacecraft Program Manager Joseph F. Shea a possible extension of Apollo systems to permit more extensive exploration of the lunar surface. Huntsville's concept, called the Integrated Lunar Exploration System, involved a dual Saturn V mission (with rendezvous in lunar orbit) to deliver an integrated lunar taxi/shelter spacecraft to the Moon's surface.

The 3L vehicle, without its payload (which was on the 1M1 mockup), is erected on the pad to test engine systems. References: 96 .

Passive naval electronic intelligence satellite. The satellite was placed in an initial 147 km x 442 km orbit at 65 degree inclination. The US-PM's propulsion module fired at apogee to circularize the orbit. Replaced the only previous remaining US-PM satellite which ended operations in November and reentered earlier in December 1999.
