The 1960 and 1962 Soviet Mars Mission Attempts by Selby Cull
Sent to Kolyma gold mine prison camp during Stalin’s purges, convicted of “subversion in a new field of technology” • the Kolyma prison, in Siberia, had one of the highest death rates among Stalin’s gulags: an average of 200,000 prisoners died there every year--- 30% of the prison’s population • Korolev survived, but lost all his teeth, suffered a broken jaw, nearly died of scurvy, and acquired a serious heart condition that would eventually cause his death.
Leading up to 1960 • 4 October 1957: Sputnik 1 • 1 February 1958: US launches Explorer 1 • Rest of 1958 = bunch of failed lunar missions from both US & USSR • 2 January 1959: Luna 1 • 3 March 1959: Pioneer 4 from US • Rest of 1959 = Luna 2 and Luna 3 and failure of Pioneer P-3 from US
Good Things for Soviets: • Beat Americans by being first into orbit • Beat Americans by being first to the Moon • Beat Americans in number of Moon missions (3 to 1) Khrushchev thinks: why not beat Americans to Mars?
The First Mars Mission • 1960: Khrushchev orders Korolev to produce a fly-by of Mars • UN meeting! • Khrushchev then places Field Marshal Mistrofan Nedelin in charge of the Mars attempt
10 October 1960 • Marsnik 1 launches atop a Sapwood (R-7) rocket • third stage boosters fail • rocket glides up to 120 km then falls back down Failure = due to rocket. Khrushchev = not pleased.
14 October 1960 • Marsnik 2 launches atop a Sapwood (R-7) rocket • third stage boosters fail • rocket glides up to 120 km then falls back down Failure = due to rocket. Khrushchev = livid.
one more try . . . . • prototype readied • scheduled for launch on 23 October, under enormous political pressure
23 October 1960 • Those present for launch: • Mikhail Yangel (Korolev’s chief deputy) • General Nikolai Pavlovsky (Deputy Chief of Staff of the Soviet Armed Forces) • Dmitri Yefremov (leader of the Soviet nuclear science program) • Ivan Gvay (one of Russia’s top rocketry experts)
What caused the failures? • Marsnik 1: faulty fuel feed system in Sapwood rocket’s third stage boosters • Marsnik 2: same problem • Third Probe: cause of explosion unknown . . . . but the Sapwood had the same problems as the first two
The MV4 • designed to explore Mars or Venus • heaviest planetary probe at the time (~900 kg) • about the weight of a large buffalo
24 October 1962 • SL-6 Molniya rocket (pictured left) used to launch the fourth Soviet attempt at a Mars probe • (BTW: Cuban Missile Crisis began 18 October, ended 29 October)
1 November 1962 • Mars 1 probe launched atop another SL-6 Molniya rocket • Actually left Earth orbit & headed for Mars!
. . . . only to malfunction on 21 March 1963. A breakdown of the probe’s orientation system ended up pointing the transmitters away from Earth, and contact was lost. Mars 1 probably passed by Mars, but there’s no way to know.
4 November 1962 • Last of the 1962 Mars attempts was launched atop another SL-6 Molniya rocket. It blew up in Earth orbit, and pieces eventually reentered the atmosphere and landed in the ocean
Summary: 1960 and 1962 missions • 1960 • Marsnik 1 = launch failure • Marsnik 2 = launch failure • third probe = exploded on launch pad • 1962 • MV4-1 = blew up in atmosphere • Mars 1 = contact lost en route to Mars • MV4-2 = blew up in atmosphere
