Today is the 50th anniversary of Soyuz 17's launch on a month-long mission to Salyut 4. The first of two long-duration expeditions to the civilian station gave confidence for the more advanced expeditions to Salyut 6 & 7 from 1977 until 1986, & Mir between 1986 and 2001.

09.02.1975 po trwającym 188 s manewrze deorbitacyjnym aparat powrotny Sojuza 17 wylądował po osiągnięciu nowego radzieckiego rekordu w lotach załogowych.

Astro Info Service @aisoffice 8:42 AM · Feb 9, 2025
Ending a flight of 29+ days the DM of Soyuz 17 landed, OTD 1975, 110 km NE of Tselinograd, Kazakhstan. Salyut 4's EO-1 "Zenit" crew (Aleksei Gubarev & Georgy Grechko) completed a productive Salyut mission, surpassing the 23+ day mission of the ill-fated Soyuz 11 crew set in 1971.

05.04.1975 o 11:04:54,038 UTC z wyrzutni LC1 kosmodromu Bajkonur wystartowała RN Sojuz 11A511 ze
statkiem załogowym Sojuz (Sojuz 18-1).
Podczas wykonywania sekwencji rozdzielania drugiego i trzeciego stopnia nie doszło do ich rozdzielenia.
Wobec przekroczenia parametrów lotu ponad wyznaczony limit, została uruchomiona awaryjna procedura powrotu statku kosmicznego na Ziemię.

Osiągnięta przez  Sojuz 18-1 wysokość 192 km, pozostaje do dziś rekordowa dla załogowych lotów suborbitalnych.
Lot załogi trwał 21m 27s.
Załoga miała spędzić na stacji Salut-4 do ok. 2 miesięcy.

1975 April 5 - . 11:04 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC1. LV Family: R-7. Launch Vehicle: Soyuz 11A511. FAILURE: During second-third stage separation third stage failed to separate from second stage but still ignited.. Failed Stage: 3.

Soyuz 18-1 - . Call Sign: Ural (Urals ). Crew: Lazarev, Makarov. Backup Crew: Klimuk, Sevastyanov. Payload: Soyuz 7K-T s/n 39. Mass: 6,830 kg (15,050 lb). Nation: Russia. Related Persons: Klimuk, Lazarev, Makarov, Sevastyanov. Agency: RVSN. Program: Salyut. Class: Manned. Type: Manned spacecraft. Flight: Soyuz 18-1. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-T. Duration: 0.0149 days. Decay Date: 1975-04-05 . Apogee: 192 km (119 mi).

Carried Oleg Makarov, Vasili Lazarev for rendezvous with Salyut 4; but during second-third stage seperation third stage failed to separate from second stage but still ignited. The crew demanded that the abort procedures be implemented but ground control could not see the launch vehicle gyrations in their telemetry. Soyuz finally was separated from by ground control command at 192 km, and following a 20.6+ G reentry, the capsule landed in the Altai mountains, tumbled down a mountainside, and snagged in some bushes just short of a precipice. The crew was worried that they may have landed in China and would face internment, but after an hour sitting in the cold next to the capsule, they were discovered by locals speaking Russian. Total flight duration was 1574 km and flight time 21 minutes 27 seconds. Lazarev suffered internal injuries from the high-G reentry and tumble down the mountain side and never flew again. Both cosmonauts were denied their 3000 ruble spaceflight bonus pay and had to apeal all the way to Brezhnev before being paid.

Il y a donc 50 ans - l'équipage rentre d'urgence après avoir atteint 192 km d'altitude et atterrit 21 minutes après le décollage.

Il y a 45 ans, lancement de Soyouz 18A (ou 18-1) avec Oleg Makarov et Vassili Lazarev vers la station saliout. Le 3ème étage ne se sépare pas et les 2 hommes reviennent assez sportivement sur Terre après avoir atteint une altitude de 192 km (vol suborbital)

5 April 1975. Launch of Soyuz 18a (Soyuz 18-1) to dock with the orbiting Salyut 4 space station. Failed to achieve orbit. Commander Vasily Lazarev and civilian flight engineer Oleg Makarov feared they had landed in China but were successfully recovered from the Altay Mountains.

Intending to spend 60d on Salyut 4, Vasily Lazarev & Oleg Makarov survived a high altitude aborted launch OTD 1975. In minutes, they experienced up to 21.3 g, landed on a snow-covered slope (-7 C), sliding towards a 152m sheer drop,stopped by the parachutes snagging on vegetation

Cosmonauts escape a close call launch
Last update: April 9, 2025

(...) On April 6, 1975, or around 24 hours after the accident, the Soviet TASS news agency issued a statement with an unprecedented admission of the Soyuz launch failure. It said that during the third-stage operation, the rocket had deviated from its prescribed path triggering an automated separation of the spacecraft for the return to Earth. The statement also disclosed that the Descent Module had made a soft landing near the town of Gorno-Altaysk in Western Siberia and that cosmonauts Vasily Lazarev and Oleg Makarov were returned to the cosmodrome in good health. (50)

It is not exactly clear why the Soviet authorities decided to make the fact of the accident public, since a suborbital ballistic flight could easily be concealed unlike any orbital mission which would almost universally be tracked by foreign radar after its first full orbit. According to one hypothesis, Soviet officials were concerned that during ongoing preparations for the joint Apollo-Soyuz mission, involving multiple contacts between the American and Soviet space officials, rumors could start circulating, souring the atmosphere around the upcoming historic flight. A complete denial of the accident could lead to a lack of trust between the two sides especially when it involved the performance of a system directly involved in the joint flight. (...)
