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.

  • Mir News 355: Mir-routine - . Nation: Russia. Program: Mir. Flight: Mir NASA-3; Mir EO-23. Immediately after the opening of the hatches to Progress-M34 the crew began to unload the most important stuff for direct use. They used a part of the new arrived pure oxygen supply and new lithium perchlorate 'disks' for oxygen production. Radio traffic revealed that the cosmonauts without delay had started the repair of the Elektron system in Module-D (Kvant- 2). On 11.04 this Elektron was activated, but after a few minutes during which oxygen was produced it switched itself off. On the days to follow the crew regularly worked on this system and to undo the last failure they even used a part of the unserviceable Elektron in Module-E (Kvant-1).

    The urgent work on the Elektron caused a considerable work overload of the crew. These days the astronaut Linenger is often deployed to assist in this repair work for which he has to refrain from a part of his American experiments. A few times the work on the Elektron had to be suspended for the execution of repair work with a higher priority. This had to do with a lot of leakage in the heating- and cooling circuits in the Base Block and Kvant-1.

    The leaks in the cooling loops in Kvant-1 caused the outflow of cooling liquid (ethylene glycol) and the decrease of the pressure within that circuit. A sufficient cooling is also needed for the functioning of the carbon dioxide (CO2) absorber Vozdukh. For the neutralisation of CO2 in Mir's atmosphere there is another alternative. Progress-M34 delivered for that purpose canisters lithium hydroxide. Meanwhile the Elektron in Module-D and the Vozdukh CO2 scrubber are functioning. The problems with the life support systems on board caused a high humidity and consequently a lot of condensation. Twice a day Tsibliyev can be heard reporting pulse rates, blood pressures, skin temperatures and blood oxygen saturation of all crew members.

    Orbit correction: Using the engines of the Pr-M34 the orbit of the Mir-station had been corrected on 15.04.19997 at 12.46.01 UTC. Apogee and Perigee changed from 397.16/381.63 KM to 402.54/389.51 KM.

    Solar orbit: Within a few days Mir will enter a so called solar orbit. During this period Mir will continuously remain in sunlight. Then it will be more difficult to control the on board temperatures. Tsibliyev said that physically the crew is able to sustain this inconvenience, but that he has some concerns about the equipment of the complex.

    1st Spacewalk (EVA) Mir Main Expedition 23/ NASA 4: This EVA is (or possibly meanwhile: was) on schedule for 29.04.1997. The EVA will be executed if the repair work can be accomplished before a determined deadline.

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.

Nation: USA. Related Persons: Rominger; Ashby; Hadfield; Phillips; Parazynski; Guidoni; Lonchakov. Agency: NASA Houston. Manufacturer: Boeing. Program: ISS. Class: Manned. Type: Manned spaceplane. Flight: STS-100. Spacecraft: Endeavour. Duration: 11.90 days. Decay Date: 2001-05-01 . USAF Sat Cat: 26747 . COSPAR: 2001-016A. Apogee: 404 km (251 mi). Perigee: 378 km (234 mi). Inclination: 51.6000 deg. Period: 92.40 min. 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
    Endeavour reached an 80 x 317 km orbit at 1849 GMT; at 1924 GMT the OMS engines fired to raise perigee. After a series of rendezvous burns, the spaceship docked with the PMA-2 port on the ISS at 1359 GMT on April 21.

    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.
