Rocket had strainers and thicker air vanes; duration of propulsion, 14 sec; altitude 6600 ft with excellent correction up to 3000 ft; parachute torn off. References: 482 .
Gas composition research. Launched at 2359 local time. Reached 69.2 km.
Launched at 0130 hours EST from AMR. The primary test objective was to test the accuracy of the guidance system. The flight was successful. Actual range was 130.125 nm; 0.15 nm over; and 285 meters left of the intended impact point. All missions were successfully accomplished. The missile followed the predicted trajectory very closely. Survey of the impact crater indicated a miss distance of 50 meters over and 284 meters to the left of the predicted impact point, giving a radial miss distance of 389.5 meters. Missed aimpoint by 289 m. References: 439 .
The astronauts underwent a five and one half day course in 'desert survival' training at the Air Training Command Survival School, Stead Air Force Base, Nevada. The possibility of an arid-area landing was remote but did exist. So this training was accomplished to supply the astronaut with the confidence and ability to survive desert conditions until recovery. The course consisted of one and one half days of academics, one day of field demonstrations, and three days of isolated remote-site training. Survival equipment normally installed in the Mercury spacecraft was used to provide the most realistic conditions. References: 483 .
Jet Propulsion Laboratory announced that construction was under way on the first large space simulator in the United States capable of testing full-scale spacecraft of the Ranger and Mariner classes. Three primary space effects could be simulated: solar radiation, cold space heat sink, and a high vacuum equivalent to about one part in a billion of the atmospheric pressure at sea level.

NASA Headquarters Gemini Program Office informed Manned Spacecraft Center that it had decided to delete extravehicular activity from Gemini missions 5, 6, and 7.
First of two Mars missions to Mars' moon Phobos; carried two landers; entered Mars orbit 1/29/89; failed 3/27/89; extremely limited science data. Phobos 2 operated nominally throughout its cruise and Mars orbital insertion phases, gathering data on the Sun, interplanetary medium, Mars, and Phobos. Shortly before the final phase of the mission, during which the spacecraft was to approach within 50 m of Phobos' surface and release two landers, one a mobile 'hopper', the other a stationary platform, contact with Phobos 2 was lost. The mission ended when the spacecraft signal failed to be successfully reacquired on 27 March 1989. The cause of the failure was determined to be a malfunction of the on-board computer.

Commsat technology demonstration;19 deg W. Olympus-1 is a multi-payload communications satellite for direct TV broadcast in the bands of the 1977 Geneva Plan of the International Telecommunications Union (ITU) (including a national beam to Italy) plus communication transponde rs in the 14/12 GHz, 2nd 30/20 GHz bands. The latter are also used for a data relay experiment with ESA's EURECA satellite. Position on geostationary orbit 341 deg E. Launch time 0014:00 UT. References: 1 , 2 , 5 , 6 .
It entered Jupiter's atmosphere on 1995.12.07.
Years behind schedule, the Zvezda living module of the International Space Station, built and financed by Russia, finally reached orbit. Zvezda's initial orbit was 179 x 332 km x 51.6 deg. On July 14 the orbit was raised to 288 x 357 km. ISS was then in a 365 x 372 km orbit. After matching orbits with the ISS, Zvezda then became the passive docking target for the Russian-built, US-financed Zarya module already attached to the station. The Zarya/Unity stack docked with the Zvezda module at 00:45 GMT on July 26, forming the basic core of the International Space Station. A flood of NASA missions would follow to bring the station into operation.
