The fourth Jupiter was fired from AMR at 1602 hours EST over IRBM range and was the second successful flight of the series. The range error was 27.5 nm with a 36.5 nm lateral error. Range was predicted for 146 nm. LOX was cut off at 170 seconds. All flight missions were fulfilled satisfactorily. Separation occurred 5 seconds after burnout, as programmed, This was the first test of separation of body from thrust unit.

NASA Headquarters authorized the Space Task Group to enter into negotiations with the Air Force Ballistic Missile Division for the procurement of additional Atlas launch vehicles in support of Project Mercury. The authorization was to be incorporated into Contract No. HS-36.

The Little Joe II qualification test vehicle was launched from White Sands Missile Range, N Mexico. Its objectives were to prove the Little Joe's capability as an Apollo spacecraft test vehicle and to determine base pressures and heating on the missile. These aims were achieved. The lone failure was a malfunction in the destruct system.

An Air Force Thor/Agena B was launched from Vandenberg and placed NASA's first Nimbus meteorological satellite into orbit. Returned 27,000 cloud cover images. The spacecraft carried an advanced vidicon camera system for recording and storing remote cloudcover pictures, an automatic picture transmission camera for providing real-time cloud cover pictures, and a high-resolution infrared radiometer to complement the daytime TV coverage and to measure nighttime radiative temperatures of cloud tops and surface terrain. A short second-stage burn resulted in an unplanned eccentric orbit. Otherwise, the spacecraft and its experiments operated successfully until September 22, 1964. The solar paddles became locked in position, resulting in inadequate electrical power to continue operations.

It is becoming clear that in order to ever get Soyuz into space it is necessary to clear all decks at OKB-1. After Voskhod-2 the Soviet manned space plans are in confusion. The Americans have flown Gemini 5, setting a new 8-day manned space endurance record - the first time the Americans are ahead in the space race. They rubbed salt into the Soviet wound by sending astronauts Cooper and Conrad on a triumphal world tour. This American success is very painful to Korolev, and contributes to his visibly deteriorating health. In the absence of any coherent instructions from the Soviet leadership, Korolev makes a final personal decision between the competing manned spacecraft priorities. Work on completing a new series of Voskhod spacecraft and conducting experiments with artificial gravity are unofficially dropped and development and construction of the new Soyuz spacecraft is accelerated. The decision is shared only with the OKB-1 shop managers. One of Korolev's "conspirators" lays on Chertok's table the resulting new Soyuz master schedule. The upper left of the drawing has the single word "Agreed" with Korolev's signature. The only other signatures are those of Gherman Semenov, Turkov and Topol - Korolev has ordered all other signature blocks removed. Chertok is enraged. The plan provides for the production of thirteen spacecraft articles for development and qualification tests by December 1965! These include articles for thermal chamber runs, aircraft drop tests, water recovery tests, SAS abort systems tests, static and vibration tests, docking system development rigs, mock-ups for zero-G EVA tests aboard the Tu-104 flying laboratory, and a full-scale mock-up to be delivered to Sergei Darevskiy for conversion to a simulator. Chertok is enraged because the plan does not include dedicating one spaceframe to use as an 'iron bird' hot mock-up on which the electrical and avionics systems can be integrated and tested. Instead two completed Soyuz spacecraft are to be delivered to OKB-1's KIS facility in December and a third in January 1966. These will have to be used for systems integrations tests there before being shipped to Tyuratam for spaceflights.

MSFC issued a modification to an existing contract with McDonnell Douglas for Skylab Program work. The modification would pay for the conversion of the original OWS to be launched by a Saturn IB booster to a completely outfitted Workshop to be launched by a Saturn V. Originally the plan was to launch the second stage (S IVB) of a Saturn IB into Earth orbit. The S-IVB would be filled with fuel so that it could propel itself into orbit. Astronauts launched by a second Saturn IB would then rendezvous with the empty stage and convert it into living and working quarters. A decision was made 21 May 1969 to outfit an S-IVB on the ground and launch it ready for use on a Saturn V.

Japanese DBS; 110 deg E. Continuation of broadcasting services by BS-2; accommodations to increasing and diversifying demands for broadcasting; establishment of common technology necessary for broadcasting satellite. Launching organization NASDA. Launch time 0905 GMT. BS-3a 'Yuri -3a'. Positioned in geosynchronous orbit at 110 deg E in 1990-1998 As of 2 September 2001 located at 84.62 deg E drifting at 5.278 deg W per day. As of 2007 Mar 10 located at 83.70W drifting at 5.275W degrees per day.

Geosynchronous. Stationed over 58.0W. Used HS-601 XIPS ion engine for station keeping. Positioned in geosynchronous orbit at 58 deg W in 1997-1999 As of 5 September 2001 located at 156.02 deg W drifting at 1.125 deg W per day. As of 2007 Mar 11 located at 26.11E drifting at 0.002W degrees per day.

The hatch between Mir and Soyuz was closed at 18:12 GMT on August 27, 1999. Soyuz TM-29 undocked from Mir at 21:17 GMT with Afanasyev, Avdeyev and Haignere aboard. The Mir EO-27 crew landed in Kazakhstan at 00:35 GMT on August 28. Afanasyev had set a new cumulative time in space record, but for the first time since September 1989 there were no humans in space.

Raduga-1 military communications satellite initially named Cosmos 2372 by the RVSN press service. Stationed at 50 deg E. As of 5 September 2001 located at 49.25 deg E drifting at 0.048 deg W per day. As of 2007 Mar 10 located at 45.70E drifting at 0.012W degrees per day.

Launch delayed from August 27. Atlantic Bird was a European (EUTELSAT) geostationary communications spacecraft. The 2.7-ton (1550 kg dry with 1150 propellant), 5 kW satellite was to provide voice, video, and Internet services to Europe and the eastern part of America through its 24 transponders after being parked over 12.5° W. As of 2007 Mar 10 located at 12.49W drifting at 0.006W degrees per day.

Launch delayed from August 27. MSG 1 (Meteosat Second Generation 1) was a European (EUMETSAT consortium) geostationary weather satellite. After first being parked over 10° E longitude for six months it was later to be moved to zero degree longitude. As of 2007 Mar 7 located at 3.50W drifting at 0.015W degrees per day.

Padalka, Kelly and Kornienko flew Soyuz TMA-16M from the Poisk to Zvezda docking ports. Undocking from Poisk was at 07:12 GMT and docking with Zvezda was at 07:30 GMT. This freed the Poisk port for the TMA-18M arrival, and freed Zvezda for a refuelling spacecraft once TMA-16M returned to Earth.
