April 12 Chronology


1925 April 12 - .
1928 April 12 - . Launch Vehicle: Opel.
  • Opel Rak - . Nation: Germany. Related Persons: Valier; Opel. After two tests the day before, which showed that a good fraction of Brander's rockets would either fail to ignite or explode, Valier made the first official rocket car run for the press. Of 12 rockets attached to the 'Rak' vehicle (a motor car stripped of engine and brakes), five failed to function, but the vehicle reached 110 kph and the press was mightily impressed. Opel received an unexpected amount of free publicity and funded Valier in further rocket car development.

We are, I hope, going to be able to carry out our efforts, with due regard to the problem of the life of the men involved, this year. But we are behind . . . the news will be worse before it is better, and it will be some time before we catch up. . . ."

  • HETS A2-2 Plasma mission - . Nation: USA. Agency: USAF. Apogee: 1,931 km (1,199 mi).

1961 April 12 - . 06:07 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Vostok 8K72K. LV Configuration: Vostok 8K72K E103-16.
  • Vostok 1 - . Call Sign: Kedr (Cedar ). Crew: Gagarin. Backup Crew: Titov; Nelyubov. Payload: Vostok 3KA s/n 3. Mass: 4,725 kg (10,416 lb). Nation: USSR. Related Persons: Korolev; Keldysh; Rudnev; Karpov; Moskalenko; Gagarin; Titov; Nelyubov. Agency: RVSN. Program: Vostok. Class: Manned. Type: Manned spacecraft. Flight: Vostok 1. Spacecraft: Vostok. Duration: 0.0750 days. Decay Date: 1961-04-12 . USAF Sat Cat: 103 . COSPAR: 1961-Mu-1. Apogee: 315 km (195 mi). Perigee: 169 km (105 mi). Inclination: 65.0000 deg. Period: 89.30 min. First manned spaceflight, one orbit of the earth. Three press releases were prepared, one for success, two for failures. It was only known ten minutes after burnout, 25 minutes after launch, if a stable orbit had been achieved.

    The payload included life-support equipment and radio and television to relay information on the condition of the pilot. The flight was automated; Gagarin's controls were locked to prevent him from taking control of the ship. The combination to unlock the controls was available in a sealed envelope in case it became necessary to take control in an emergency. After retrofire, the service module remained attached to the Sharik reentry sphere by a wire bundle. The joined craft went through wild gyrations at the beginning of re-entry, before the wires burned through. The Sharik, as it was designed to do, then naturally reached aerodynamic equilibrium with the heat shield positioned correctly.

    Gagarin ejected after re-entry and descended under his own parachute, as was planned. However for many years the Soviet Union denied this, because the flight would not have been recognized for various FAI world records unless the pilot had accompanied his craft to a landing. Recovered April 12, 1961 8:05 GMT. Landed Southwest of Engels Smelovka, Saratov. Additional Details: Vostok 1.

  • Chaos at Area 31. - . Nation: USSR. Related Persons: Kerimov; Mishin; Grechko, Andrei. Program: Soyuz; Lunar L1. Flight: Soyuz 1; Soyuz 2A. Spacecraft: Soyuz 7K-OK. The cosmonauts began work at 10:30 in the morning, and didn't complete work until 23:30 at night. They spent 16 hours working on Cosmonaut's Day, due to the criminally chaotic performance of TsKBEM. The cosmonauts have to train simultaneously for the Soyuz and L1 missions. Kamanin warns Kerimov about the unacceptable situation. Grechko arrives to head the state commission. The launch of Soyuz 1 is set for 24-25 April - there will be only eight days to fix all of the problems. The energy and optimism of Korolev is sorely missed. Mishin was a poor deputy, and a worse leader - his constant mistakes and stupidity delay work and aggravate people. The cosmonauts have to keep in shape by playing tennis, but there is only one court at Tyuratam - a second court is to be built eventually (!)

  • Kvant docks to Mir - . Nation: USSR. Flight: Mir EO-2. Spacecraft: Kvant. It managed to dock to Mir on the third attempt after the crew removed a trash bag from the docking collar in a space walk. The FGB tug, its work done, then backed away from the station. But the manoeuvres had cut into its already-reduced propellant supply. Unable to deorbit itself to a controlled burn-up in the atmosphere, the FGB was instead commanded to boost itself into a storage orbit 40 km above Mir.

  • Mir News 250: Progress-M27 - . Nation: Russia. Program: Mir. Flight: Mir EO-18. This freighter started from Baykonur on 9.04.95 at 1933 UTC. After a 2-days flight during which no problems emerged Progress-M27 docked to the forward (P.Kh.O. - transition section) of the Mir complex on 11.04.1995 at 2100 UTC (21 hrs 00 mins 42 seconds), so on 12.04.1995 at 0100 Moscow Summer Time. Approach and docking took place in the automatic mode by the system Kurs. Dezhurov was ready to take over manually by the remote control system TORU, but this was not necessary. Progress-M27 docked during Mir's orbit 52262. During the final approach and docking traffic was relayed by Altair. There were no TV-images. Dezhurov reported details of the approach and the soft docking (kasanye). During the next pass in orb. 52263, at 2227 UTC Strekalov reported that they had opened the hatch to Progress-M27 2 minutes earlier and that everything was in good order. Progress-M27 delivered to the complex the normal cargo (water, food, fuel, post, underwear, scientific material, etc.), repair materials for the systems to maintain a good atmosphere and the water generation and the German micro-satellite GFZ-1.

    GFZ-1: So this little satellite is now on board of the Mir- complex waiting for its 'second' launch. This has to be done by the cosmonauts in the night from 19 to 20.04.1995. This spherical object with a mass of 20 KG and a diameter of 21 CM will separate from Mir with a speed of 1.2 M/sec. During this operation the German tracking station Oberpfaffenhofen will play an important role. (For details about GFZ-1 see Mir-

    NEWS.249)

    During the pass in which Strekalov reported the opening of the hatch, TsUP told him that the first EVA will take place on 11.05.1995. The date for the launch of Spektr (thus far on schedule for 20.05.1995) might be changed. After the launch of the Spektr, so during one of its 7-days autonomous flight, Progress-M27 will be separated from Mir.

    Possible launch date of Atlantis for the flight in which she has to dock to Mir: 22.06.1995. If so the flight of the Disco very might be put forward to 6.06.1995. This all is not sure at this moment.

  • ISS On-Orbit Status 04/12/08 - . Nation: USA. Related Persons: Kononenko, O D; Love; Malenchenko; Reisman; Volkov, Sergey; Whitson; Yi So-yeon. Program: ISS. Flight: ISS EO-16. Day 3 of joint E16/E17 operations by CDR-16 Peggy Whitson, FE-1-16 Yuri Malenchenko, FE-2-17 Garrett Reisman, CDR-17 Sergei Volkov, FE-1-17 Oleg Kononenko and SFP/VC14 So-Yeon Yi.

    Today Russia observes Denj Kosmonavtov (Cosmonauts Day) and the world Yuri's Night -- celebrating Yuri Alexeyevich Gagarin's pioneering flight into space 47 years ago. And NASA is observing the 27th anniversary of STS-1, the first Space Shuttle mission to orbit. (Yuri was accepted into the cosmonaut unit in 1960, at age 26. After his historic 108-min. flight around the Earth in 'Vostok 1', which ended with a parachute ejection at 7 km altitude over a farm field near the city of Engels in Saratov Oblast (province), he was promoted to unit leader. Seven years later, on March 27, 1968, Yuri died with a flight instructor in a fighter jet crash. Chief Designer of the thusly inaugurated Soviet human space program was Sergey Pavlovich Korolev. Exactly 20 years later, John Young and Bob Crippen took the Columbia into space for a test mission lasting 2 days 6 hours 20 minutes 52 seconds.) Additional Details: ISS On-Orbit Status 04/12/08.
