Voskhod 1

Voskhod 1 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Voskhod 1 rather than just read about it. In short: Voskhod 1 (Russian: Восход-1, lit. 'Sunrise-1') was the seventh crewed Soviet space flight. Flown by cosmonauts Vladimir Komarov, Konstantin Feoktistov, and Boris Yegorov, it launched 12 October 1964, and returned on the 13th.

Key takeaways

  • Voskhod 1 belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Voskhod 1 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Voskhod 1 from memory before moving on to harder problems.

Reference excerpt

Voskhod 1 (Russian: Восход-1, lit. 'Sunrise-1') was the seventh crewed Soviet space flight. Flown by cosmonauts Vladimir Komarov, Konstantin Feoktistov, and Boris Yegorov, it launched 12 October 1964, and returned on the 13th. Voskhod 1 was the first human spaceflight to carry more than one crewman into orbit, the first flight without the use of spacesuits, and the first to carry either an engineer or a physician into outer space. It also set a crewed spacecraft altitude record of 336 km (209 mi). The three spacesuits for the Voskhod 1 cosmonauts were omitted; there was neither the room nor the payload capacity for the Voskhod to carry them. The original Voskhod had been designed to carry two cosmonauts, but Soviet politicians pushed the Soviet space program into squeezing three cosmonauts into Voskhod 1. The only other space flight in the short Voskhod program, Voskhod 2, carried two suited cosmonauts – of necessity, because it was the flight on which Alexei Leonov made the world's first walk in space. As part of its payload Voskhod 1 carried a ribbon off a Communard banner from the Paris Commune of 1871 into orbit.

Background

The original prime crew of cosmonauts for Voskhod 1, composed of Boris Volynov, Georgi Katys, and Boris Yegorov, was rejected just three days before the scheduled launch date for the space capsule. Katys was reportedly removed after the KGB discovered that his father had been shot during the Great Purge in 1937 and Volynov apparently was the victim of discrimination due to his part-Jewish background, although he would later fly on Soyuz 5 and Soyuz 21. Politics played a role in the crew's selection. Various factions each supported their own representatives for the flight. Sergei Korolev wanted his engineers to become cosmonauts, believing that spacecraft designers should fly in their own vehicles. The Soviet Air Force agreed to a crew composed of a military pilot, an engineer or scientist, and a doctor, but advocated for an all-military crew. Konstantin Feoktistov, who had been a design engineer for the Vostok, Voskhod, and Soyuz programs, was selected for this flight, becoming the only Soviet outer space designer to make a spaceflight. Yegorov, a medical doctor, used his political influence to get selected for the crew through his father's Politburo connections. The Soviet space program viewed its crews as passengers more than pilots; the new cosmonauts received only three to four months of training, perhaps the briefest in space history other than that received by the American politicians Jake Garn and Bill Nelson for Space Shuttle flights in the 1980s.

Mission highlights

The Voskhod spacecraft were basically Vostok spacecraft with a backup solid-fuel retrorocket added onto the top of the descent module. The ejection seat was removed and three crew couches were added to the interior at a 90-degree angle to that of the Vostok cosmonaut's position. Because of the cramped conditions, the cosmonauts also had to go on a diet to fit in their couches. A solid-fuel braking rocket was also added to the space capsule's parachute lines to provide for a softer landing at touchdown. This was necessary because, unlike the Vostok space capsule, no ejection seats were fitted in the Voskhod; the cosmonauts had to land inside the descent module. Aside from that, the Vostok booster had lacked sufficient payload capacity to support the extra weight of a retrorocket package, but the larger upper stage used on the 11A57 launch vehicle meant that this was no longer an issue. As there was no launch escape system, the mission could not be aborted until three minutes after liftoff when the payload shroud was jettisoned and so a low-altitude booster accident would have meant the loss of the crew. Liftoff took place at 7:30 on the morning of 12 October. Much of the mission of Voskhod 1 was devoted to biomedical research, and to the study of how a multidisciplinary team could work together in space. The mission was short, at only slightly over 24 hours. The Soviet premier Nikita Khrushchev was removed from power during the spaceflight, and it has been speculated that this led to the mission being cut short. The cramped conditions of the Voskhod space capsule has also been suggested as a factor ruling out a longer-duration spaceflight. During the flight, Khrushchev spoke with the cosmonauts via radio phone from his dacha in the Crimea. Shortly after this conversation, he was summoned back to Moscow where he learned that he was being expelled from office and the Communist Party. When the crew returned to Earth the next day, they were greeted by Leonid Brezhnev and Alexei Kosygin in their first public appearance as leaders of the Soviet Union. Despite the propaganda boasting around Voskhod 1, it was privately referred to by the leadership of the Soviet space program as "a circus" due to the messy process of crew selection, the cosmonauts needing to diet to fit inside their spacecraft, Khrushchev's expulsion during the flight, and also the extremely dangerous circumstances of it (the crew having neither pressure suits nor any way to escape from a malfunctioning launch vehicle).

Happening as it did before the beginning of the Project Gemini two-man flights, Voskhod 1 had a significant, but temporary, international impact. The NASA Administrator, James E. Webb, called the flight of Voskhod 1 a "significant space accomplishment" adding that it was "a clear indication that the Russians are continuing a large space program for the achievement of national power and prestige."

Worked examples

Example 1 — a first encounter with Voskhod 1

Start with the simplest possible case. Write down what Voskhod 1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Voskhod 1 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Voskhod 1 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Voskhod 1

In research
Voskhod 1 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Voskhod 1 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Voskhod 1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1964 in the Soviet Union, Crewed Voskhod missions, October 1964, so understanding it makes those chapters shorter.
In everyday life
Look for Voskhod 1 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
