Fired from AMR at 1934 hours EST. The primary mission of impacting a nose cone in a pre-calculated target area (MILS Network) was successfully accomplished with an impact of 0.8 nm under end 5.0 nm to the left of the 1,302 nm range. The lateral miss was believed to have been caused by a drifting gyro. References: 439 .

Preliminary specifications were issued by Space Task Group (STG) to modify the Mercury capsule by adding a reentry control navigation system. The modified capsule would obtain a small lifting capability (lift-over-drag ratio would equal approximately 0.26). The self-contained capsule navigation system would consist of a stable platform, a digital computer, a possible star tracker, and the necessary associated electronic equipment. Dispersion from the predicted impact point would be less than 10 miles. The prospective development called for a prototype to be delivered to NASA for testing in February 1961; and first qualified system, or Modification I, to be delivered by August 1961; and the final qualified system, or Modification II, to be delivered by January 1962. STG anticipated that four navigational systems (not including prototype or qualification units) would be required.

John C. Houbolt of the Langley Research Center presented a paper at the National Aeronautical Meeting of the Society of Automotive Engineers in New York City in which the problems of rendezvous in space with the minimum expenditure of fuel were considered.

Maximum Speed - 4586 kph. Maximum Altitude - 54860 m. The X-15 was flown in a test of a new automatic control system to be used in the Dyna-Soar and Apollo spacecraft. The previous electronic control system had been automatic only while the X-15 was in the atmosphere; the new system was automatic in space as well. References: 16 , 38 , 49 , 97 .

The Apollo 204 Review Board transmitted its final formal report on the fire to the NASA Administrator. The Board noted that the reliability of the CM and the entire system involved in its operation was a requirement common to both safety and mission success. It followed that protection from fire as a hazard required much more than quick egress. The risk of fire was only one factor pertaining to CM reliability that must receive adequate consideration. Design features and operating procedures intended to reduce the fire risk must not introduce other serious risks to mission success and safety.

Carried Oleg Makarov, Vasili Lazarev for rendezvous with Salyut 4; but during second-third stage seperation third stage failed to separate from second stage but still ignited. The crew demanded that the abort procedures be implemented but ground control could not see the launch vehicle gyrations in their telemetry. Soyuz finally was separated from by ground control command at 192 km, and following a 20.6+ G reentry, the capsule landed in the Altai mountains, tumbled down a mountainside, and snagged in some bushes just short of a precipice. The crew was worried that they may have landed in China and would face internment, but after an hour sitting in the cold next to the capsule, they were discovered by locals speaking Russian. Total flight duration was 1574 km and flight time 21 minutes 27 seconds. Lazarev suffered internal injuries from the high-G reentry and tumble down the mountain side and never flew again. Both cosmonauts were denied their 3000 ruble spaceflight bonus pay and had to apeal all the way to Brezhnev before being paid. References: 42 , 32 , 33 , 60 .

Astrophysical laboratory for gamma ray observations; deployed from STS-37 4/7/91; renamed Compton Gamma Ray Observatory. The Compton Gamma Ray Observatory was intentionally deorbited on by NASA over the objections of the scientific community on June 3, 2000. NASA decided to end the mission after several orientation gyroscope failures. They felt that if another gyroscope was lost, the heavy spacecraft might eventually reenter out of control.
