Salyut 5 was the second successful Soviet Almaz space station launched from the Baikonur Cosmodrome aboard a Proton 8K82K rocket. Structurally it was similar to Salyut 3 with a mass of 19 tons and two solar panels. It featured a detachable recovery module for the return of research data and materials which was ejected on February 26^th 1977 and successfully recovered (picture shown left).
It was inhabited by two Soyuz crews and one Soyuz failed to dock:
Soyuz 21 cosmonauts Boris Volynov and Vitali Zholobov worked in the station from July 7^th to August 24^th 1976.
Soyuz 23 failed to dock on October 15^th 1976.
Soyuz 24 crew Viktor Gorbatko and Yuri Glazkov worked in the station from February 8^th to 25^th 1977.
Salyut 5 re-entered the atmosphere on August 8^th 1977 after its fuel reserves were depleted.

Salyut 6
Salyut-6
DOS 5
1977-097A
#10382

Salyut 6 was a second-generation (along with Salyut 7) Soviet space station. With Salyut 6, the Soviet space station program evolved from short-duration to long-duration stays. It was launched unmanned and crews arrived later in Soyuz spacecraft. It had two docking ports. This permitted refueling and resupply by automated Progress freighters derived from Soyuz. Progress docked automatically at the aft port, and was then opened and unlocked by cosmonauts on the station. Transfer of fuel to the station took place automatically under supervision from the ground. A second docking port also meant long-duration resident crews could receive visitors. Visiting crews often included cosmonaut-researchers from Soviet bloc countries or countries sympathetic to the Soviet Union. Vladimir Remek of Czechoslovakia, the first space traveler not from the US or USSR, visited Salyut 6 in 1978. The station received 16 cosmonaut crews, including six long-duration crews. The longest stay time for a Salyut 6 crew was 185 days. The first long-duration crew stayed for 96 days, beating the 84-day world record for space endurance established in 1974 by the last Skylab crew. The station hosted cosmonauts from Hungary, Poland, Romania, Cuba, Mongolia, Vietnam, and East Germany. Twelve Progress freighters delivered more than 20 tons of equipment, supplies and fuel. An experimental transport logistics spacecraft called Cosmos 1267 docked with Salyut 6 in 1982. The transport logistics spacecraft was originally designed for the Almaz program. Cosmos 1267 proved that large modules could dock automatically with space stations, a major step toward the multimodular Mir station and the International Space Station.
Salyut 6 had six resident crews. On 10 Dec. 1977 the first crew, Yuri Romanenko and Georgi Grechko, arrived on Soyuz 26 and remained aboard Salyut 6 for 96 days. On June 15th 1978, Vladimir Kovalyonok and Alexander Ivanchenkov (Soyuz 29) arrived and remained on board for 140 days. Vladimir Lyakhov and Valeri Ryumin (Soyuz 32) arrived on 25 Feb. 1979 and stayed 175 days. on 9 April 1980 Leonid Popov and Valeri Ryumin (Soyuz 35) arrived for the longest stay on Salyut 6, 185 days. A repair mission, consisting of Leonid Kizim, Oleg Makarov, and Gennadiy Strekhalov (Soyuz T3) worked on the space station for 12 days starting on 27 Nov. 1980. On 12 March 1981 the last crew, Vladimir Kovalyonok and Viktor Savinyikh, arrived and stayed for 75 days. During this time there were also 10 visiting missions, crews which came to bring supplies and make shorter duration visits with the resident crews.

Soyuz-33
1979-029A
#11324

(crew: N. N. Rukavishnikov, G. I. Ivanov)

Launched to bring the "Saturn" crew N. N. Rukavishnikov (USSR) and G. I. Ivanov (Bulgaria) to the Space Station Salyut 6, Soyuz-33 failed to dock with Salyut 6 as there was a malfunction of the main engine during its final approach.
The "Proton" crew aboard Salyut 6 reported flames shooting sideways from the main engine, toward the backup engine, at the time of the shutdown. The docking was called off and the "Saturn" crew made ready to return to Earth.
Unfortunately also the backup engine had difficulties and as a result, Soyuz 33 made a steep ballistic reentry with acceleration up to 10G (98 m/s²). Listen to the crew reading the landing angles.
After the short mission of 2 days finally the "Saturn" crew arrived safely on earth.

MIR Space Station
1986-017A
#16609

Mir (english peace), a Russian space station, was the world's first consistently inhabited long-term research station in space. Constructed from 1986 to 1996 using a modular design (core module launched February 20th 1986) the station was in operation for fifteen years before it was deliberately de-orbited and re-entered into the atmosphere over the South Pacific Ocean on March 23^rd 2001. 10 years after its reentry I built a model of MIR which is now in my bookshelf and a nice reminiscence of the various contacts I had with people onboard MIR.

Feb 20^th
1986 (core module)

The first crew to visit MIR were Leonid Kizim and Vladimir Soloviev. Their Soyuz T-15 spacecraft was launched on March 13^th 1986 and they docked to MIR on March 14^th. They stayed in space for 125 days and during that time even travelled from MIR to Salyut 6 and back before finally returning back to earth.

STS-135
Atlantis OV-104
2011-031A
#37736

STS-135 was the final shutttle mission. It was launched in July 8^th 2011 from Kennedy Space Center and docked to ISS on July 10^th 2011 at 15:07 UTC. STS-135 Atlantis's External Tank video downlink was received over Europe by Nils von Storch 24 minutes after launch on 2272.5 MHz FM. Normally an internal timer disables the 10 Watts s-band video transmitter onboard the External Tank (ET) about 15 Minutes after launch, to avoid interference with S-Band communication systems in Europe. On this final Space Shuttle mission however, engineers decided to disable the timer in order to capture video from the ETs perspective when it re-entries the earths atmosphere about 60 minutes after launch. Unfortunately the signal was at 4° elevation only before disappearing behind the horizon again, which is the reason why the received video is only so short. Equipment used to receive this video was a 90cm mesh dish with 3,5 turn RHCP Helix for 2250 MHz, EME103B S-Band LNA and a G1MFG S-Band video receiver. Thanks to Nils for sharing this video with us. The mission lasted 13 days ending with a landing at Cape Canaveral on July 21^st 2011 at 09:55 UTC. Please note that the .mp4-video is almost 20 MByte large.

(2014-044A)

On Saturday February 14^th 2015 ESA’s fifth and last Automated Transfer Vehicle (ATV), Georges Lemaître, undocked from the International Space Station at 13:40 GMT. Less than 30 hours later the spacecraft burnt up harmlessly in a controlled reentry over the Pacific Ocean, marking the end of the program. All 5 ATVs were built by EADS Astrium Space Transportation in Bremen/Germany and delivered in total more than 31 tons of supplies over the course of the five missions. They boosted the Station to raise its orbit numerous times and similarly moved it out of the way of space debris. The vehicles demonstrated European mastery of automated docking, a technology that is vital for further space exploration.
The image to the right “Final Goodbye” was taken by amateur photographer Alex Spiller in Saxony, Germany, shortly after ATV undocked from ISS. Travelling from west to east at around 28 800 km/h, ATV-5 is visible as a faint stripe to the right of the brighter stripe – the International Space Station ISS. This was one of the last pictures of ATV-5 before its reentry.
