It is clear that the female cosmonauts are trained and ready for an August flight, and the men (Bykovskiy, Volynov, Leonov, Khrunov) can complete training by that date. The male cosmonauts object to spending 7 to 8 days in a spacesuit in the ground spacecraft mock-up as required by the flight doctors. They don't want to spend more than 3 to 4 days.

Mk 6 re-entry vehicle

KH-7 type satellite. Space craft engaged in investigation of spaceflight techniques and technology (US Cat A).

Last of three successful Atlas/Prime missions from Vandenberg AFB (first launch on 21 December 1966).

Kamanin goes to Baikonur aboard an Il-18 for the L1 launch. This is to be the first flight demonstration of the SUS system that will use the capsule's L/D ratio of 0.3 to make a lifting re-entry. Preparations are on schedule.

Kamanin meets with the General Staff, presents the results of the study he has commissioned on the military utility of manned spaceflight, and pleads for support for his proposal to procure ten Soyuz spacecraft.

First manned space station. Salyut 1 included a number of military experiments, including the OD-4 optical visual ranger, the Orion ultraviolet instrument for characterising rocket plumes, and the highly classified Svinets radiometer. Primary objectives included photography of the earth, spectrographs of the earth's horizon, experiments with intense gamma rays, and studying manual methods for station orientation.

At 05:20 the State Commission and their guests arrive at the Area 95 observation point to view the launch. The booster takes off on schedule at 06:40 in light rain and 60 km/hr wind. The tracking station reports good orbital insertion, separation from the third stage, and antennae and solar panel deployment. But the cover of the scientific equipment bay does not separate. This will mean that many experiments cannot be accomplished. It is decided to launch the crew to the station anyway, since the station is otherwise functioning normally. The cosmonauts go to the baths in the evening. - Additional details.

KH-4B. Very successful mission and image quality was good.

High resolution photo reconnaissance satellite; returned film capsule; maneuverable; exploded in orbit.

Also designated Intercosmos Copernicus 500. Investigated solar radio-frequency radiation and the characteristics of the earth's ionosphere.

Atmospheric research. Experimental satellite for satellite technology and some scientific experiments. Launched from a cosmodrome in the USSR.

Second Soviet replenishable long-duration ‘civilian’ space station. Objectives: Continuation of scientific research on board manned space complexes in the interests of science and the Soviet national economy; testing of advanced systems and apparatus for orbital stations. Continuation of the scientific research in progress on board manned space complexes in the interests of science and the national economy; testing of advanced systems and apparatus for orbital stations. Although of the same design as Salyut 6, technical breakdowns throughout its life made Salyut 7 a much less productive station. Replaced finally by Mir. Two different TKS resupply craft, originally designed for the Almaz military station, docked with Salyut 7 to provide a larger complex. With the cancellation of Almaz, a large proportion of the experiments carried out on board had military objectives. As of January 1990 out of fuel, unable to manoeuvre, uncontrolled re-entry expected in three to four years. Re-entered in 1991 with 70 kg fuel remaining over Argentina. Controllers attempted to control impact point (set for Atlantic Ocean) by setting Salyut 7/Kosmos 1686 assembly into a tumble. This however failed and Salyut 7 re-entered February 7, 1991 04:00 GMT. Many fragments fell on the town of Capitan Bermudez, 25 km from Rosario and 400 km from Buenos Aires, Argentina. At 1 am local time the sky was lit up with hundreds of incandescent meteors travelling from Southwest to Northeast. At dawn the inhabitants discovered numerous metal fragments, which seemed to have fallen in distinct groups at various locations in the city. Luckily no one was hurt in the metallic shower. - Additional details.

Deployed from Salyut 7 5/17/82. Launched from Salyut 7. Experiments in amateur radio communications. Launched into orbit from aboard the Salyut-7 orbital scientific station.

Released 25 Romb radar calibration subsatellites.

Photo surveillance; returned film capsule.

High resolution photo reconnaissance; returned film in two small SpK capsules during the mission and with the main capsule at completion of the mission.

STS-51-D landed at 13:50 GMT.

Unmanned resupply vessel to Mir. Docked with Mir on 21 Apr 1992 23:21:59 GMT. Undocked on 27 Jun 1992 21:34:44 GMT. Destroyed in reentry on 28 Jun 1992 00:02:51 GMT. Total free-flight time 2.18 days. Total docked time 66.93 days.

Began installation of Kvant 1 solar array drive unit.

Geodetic; carried retroreflectors for ground laser ranging; delivered to Mir on Progress M-27 and deployed from Mir 4/19/95 .

Galaxy 4R carried 28 Ku-band and 28 C-band transponders. After insertion in a standard 219 x 32007 km x 7.0 deg geostationary transfer orbit, Galaxy 4R's R-4D apogee engine raised orbit to 35765 x 35792 km x 0.1 deg by April 27 and was over 67 deg W by late April. Final destination was 99 deg W. The Galaxy satellites provide US domestic telecommunications services. 4R replaces the original Galaxy 4H which failed in May 1998, putting pagers out of action across the USA. Stationed at 99 deg W. Positioned in geosynchronous orbit at 73 deg W in 2000. As of 5 September 2001 located at 98.99 deg W drifting at 0.016 deg W per day. As of 2007 Mar 11 located at 76.88W drifting at 0.001E degrees per day.

Space Shuttle OV-105 Endeavour was launched on mission STS-100 to carry out International Space Station Flight 6A continued the outfitting of the Station. The crew of four Americans, one Russian, one Canadian and one Italian were to install an 18 meter, 1,700 kg Canadian robotic arm named Canadarm-2 on the ISS, and to transport an Italian cargo container, Raffaello, which delivered 4,500 kg of supplies and equipment to the station. Total payload of 13,744 kg consisted of:

• Bay 1-2: Orbiter Docking System, External Airlock, 3 EMU spacesuits - 2160 kg including 360 kg for the 3 suits
• Bay 3 Starboard: Adapter Beam with DCSU switching unit - 180kg
• Bay 5: Spacelab Pallet with Canadarm-2 SSRMS (Space Station Remote Manipulator System, 1800 kg mass), LDA, and 56 kg UHF antenna - 3256 kg
• Bay 6 Port: Adapter Beam with IMAX Camera - 238 kg
• Bay 8-12: Rafaello Module (MPLM-2) with MPLM racks and 3400 kg cargo - 7500 kg
• Sill: Canadarm RMS 303 - 410 kg

On 23 April the SSRMS station manipulator was unberthed from the SLP Spacelab pallet at 1114 GMT and latched on to the PDGF fixture on the Destiny ISS module at 1416 GMT. This was followed at 1458 GMT with the MPLM-2 Raffaello module being moved from Endeavour's payload bay by the Shuttle's RMS and berthed to the nadir port on the ISS Unity module at 1600 GMT. Over the next few days, the cargo racks on the MPLM were transferred to Destiny. Raffaello was then unberthed from Unity at 2003 GMT on April 27 and reberthed in the rear of Endeavour's bay for return to earth at 2059 GMT.

Undocking of Endeavour was delayed by a series of computer problems at the Station. Failures in the Station's command and control computers left only one of the three computers operating.

They were all restarted by April 29, and the Shuttle RMS grappled the Spacelab pallet at 2044 GMT . The station's Canadarm-2 released it at 2106 GMT, and the RMS berthed the pallet back in the Shuttle cargo bay. Endeavour undocked from the Station at 1734 GMT on April 29. The weather in Florida was bad at the planned May 1 landing time, so Endeavour landed in California. The deorbit burn was at 1502 GMT on May 1, with landing at 1610:42 GMT on runway 22 at Edwards. Endeavour returned to the Kennedy Space Center atop a Boeing 747 SCA aircraft on May 9.

Atlantis had undocked from ISS at 1831 UTC on April 17. It returned to Earth on April 19, with a deorbit burn at 1518:59 UTC and landing on Runway 33 at KSC at 1626:57 UTC.

Soyuz TMA-4 was ISS transport mission ISS 8S and delivered the EO-9 caretaker crew of Gennadiy Padalka and Michael Fincke, together with the ESA/Netherlands Delta mission crewmember Andre Kuipers, to the Space Station. Soyuz TMA-4 docked with the nadir port on Zarya at 05:01 GMT on April 21 and the hatches to the ISS were opened at 06:30 GMT. Another gyro on the station had shut down prior to the docking and possibly would require a maintenance spacewalk to replace its failed electronics.

After Soyuz TMA-5 docked with the ISS on October 16, the EO-9 crew handed activities over to the EO-10 crew.
