FAILURE: At T+60 min 50 sec one of the four solid motors of the escape stage's BOZ unit did not fire. The resulting asymmetric torque caused the stage to lose correct attitude and three seconds after ignition of the main engine S1.5400A1 it began to tumble.

At a White House news conference, President Lyndon B. Johnson announced approval for the Department of Defense's development of the $1.5-billion Manned Orbiting Laboratory (MOL). Such a program, the President said, would bring 'new knowledge about what man is able to do in space.' Further, MOL 'will enable us to relate that ability to the defense of America.'

The unmanned suborbital Apollo-Saturn 202 mission was successfully flown - the third Saturn IB flight test and the second CM heatshield flight test. The 202 included an uprated Saturn I (Saturn IB) launch vehicle (S-IB stage, S-IVB stage, and instrument unit) and the Apollo 011 spacecraft (spacecraft-lunar module adapter, service module, command module, and launch escape system). Liftoff was from Launch Complex 34 at Cape Kennedy at 1:15 p.m. EDT. The command module landed safely in the southwest Pacific Ocean, near Wake Island 1 hour 33 minutes after liftoff. It was recovered by the U.S.S. Hornet about 370 kilometers uprange from the recovery ship (16.07 N 168.54 E). Additional Details: Apollo 202. References: 5 , 16 , 26 , 27 .

The FGB tug's multiple docking manoeuvres in April 1987 had cut into its already-reduced propellant supply. Unable to deorbit itself to a controlled burn-up in the atmosphere, the FGB was instead commanded to boost itself into a storage orbit 40 km above Mir. From there its orbit decayed until it made an uncontrolled re-entry.

Unmanned resupply vessel to Mir. Failed to dock with Mir on 27 Aug 1994. A second automatic docking attempt on 30 Aug 1994 also failed and the Progress collided with the Kvant module. A third and final attempt, manually controlled by Mir commander Yuriy Malenchenko, was successful on 2 Sep 1994 13:30:28 GMT. The Mir commander and flight engineer, Yuriy Malenchenko and Talgat Musabaev, made a spacewalk on 9 Sep 1994 to inspect the damage to the Kvant module made when the Progress collided with Kvant. Undocked on 4 Oct 1994 18:55:52 GMT, leaving the rear docking port free for Soyuz TM-20. Destroyed in reentry over the Pacific at 38.4 deg S, 137.4 deg W,on 4 Oct 1994 22:43:00 GMT. Total free-flight time 8.12 days. Total docked time 32.23 days. References: 2 , 6 , 275 .
