Question: Who was with the cosmonaut who commanded the historic Voskhod 2 mission which saw the first man walk in space in 1965 ?

full_context: Document 1: Pavel Belyayev: Pavel Ivanovich Belyayev (Russian: Павел Иванович Беляев ; 26 June 1925 – 10 January 1970), was a Soviet fighter pilot with extensive experience in piloting different types of aircraft. He was the first commander of the cosmonaut corps and the cosmonaut who commanded the historic Voskhod 2 mission which saw the first man walk in space in 1965.
Document 2: Pavel Sukhoi: Pavel Osipovich Sukhoi (Russian: Па́вел О́сипович Сухо́й ; Belarusian: Па́вел Во́сіпавіч Сухі́ ) (22 July 1895 – 15 September 1975) was a Soviet aerospace engineer. He designed the Sukhoi military aircraft until the 1970s, and founded the Sukhoi Design Bureau.
Document 3: Alexander Vasilyevich Belyakov: Alexander Vasilyevich Belyakov (Russian: Алекса́ндр Васи́льевич Беляко́в ; 21 December 1897 [O.S. 9 December] – 28 November 1982) was a Soviet flight navigator who, together with command pilot Valery Chkalov and co-pilot Georgy Baydukov, set a record for the longest uninterrupted flight in 1936 and made the first non-stop flight across the North Pole, flying from Moscow to Vancouver, Washington.
Document 4: Sukhoi: Nine years prior to the creation of the bureau, Pavel Sukhoi, a Soviet Russian aerospace engineer, took over team no. 4 of the CAHI's AGOS aviation, flying boat aviation and aircraft prototype engineering facility, in October 1930. Under Sukhoi's leadership, the team of the future design bureau started to take shape. The team, under the Tupolev OKB, produced experimental fighters such as the I-3, I-14, and the DIP, a record-breaking RD aircraft, the Tupolev ANT-25, flew by famous Soviet aviators, Valery Chkalov and Mikhail Gromov, and the long-range bombers such as the Tupolev TB-1 and the Tupolev TB-3.
Document 5: Soyuz 9: Soyuz 9 (Russian: Союз 9 , "Union 9") was a 1970 Soviet manned space flight. The two-man crew of Andrian Nikolayev and Vitali Sevastyanov broke the five-year-old space endurance record held by Gemini 7, with their nearly 18-day flight. The mission paved the way for the Salyut space station missions, investigating the effects of long-term weightlessness on crew, and evaluating the work that the cosmonauts could do in orbit, individually and as a team. It was also the last flight of the first-generation Soyuz 7K-OK spacecraft, as well as the first manned space launch to be conducted at night. To date, Soyuz 9 marks the longest manned flight by a solo spacecraft.
Document 6: First Orbit: First Orbit is a feature-length, experimental documentary film about Vostok 1, the first manned space flight around the Earth. By matching the orbit of the International Space Station to that of Vostok 1 as closely as possible, in terms of ground track and time of day, documentary filmmaker Christopher Riley and European Space Agency astronaut Paolo Nespoli were able to film the view that Yuri Gagarin saw on his pioneering orbital space flight. This new footage was cut together with the original Vostok 1 mission audio recordings sourced from the Russian State Archive of Scientific and
Document 7: Vladimir Komarov: Vladimir Mikhaylovich Komarov (Russian: Влади́мир Миха́йлович Комаро́в ; ] ; 16 March 192724 April 1967) was a Soviet test pilot, aerospace engineer and cosmonaut. In October 1964, he commanded Voskhod 1, the first spaceflight to carry more than one crew member. He became the first cosmonaut to fly in space twice when he was selected as the solo pilot of Soyuz 1, the first manned test flight of a new spacecraft. A parachute failure caused his Soyuz capsule to crash into the ground after re-entry on 24 April 1967, making him the first human to die in a space flight.
Document 8: Voskhod (spacecraft): The Voskhod (Russian: Восход , ""Sunrise"") was a spacecraft built by the Soviet Union's space program for human spaceflight as part of the Voskhod programme. It was a development of and a follow-on to the Vostok spacecraft. Voskhod 1 was used for a three manned flight whereas Voskhod 2 had a crew of two. They consisted of a spherical descent module (diameter 2.3 meters), which housed the astronauts, and instruments, and a conical equipment module (mass 2.27 tonnes, 2.25 m long, 2.43 m wide), which contained propellant and the engine system. Voskhod was superseded by the Soyuz spacecraft in 1967.
Document 9: Valentin Lebedev: Valentin Vitalyevich Lebedev (Russian: Валентин Витальевич Лебедев ; born April 14, 1942 in Moscow) was a Soviet cosmonaut who made two flights into space. His stay aboard the Space Station Salyut 7 with Anatoly Berezovoy in 1982, which lasted 211 days, was recorded in the Guinness Book of Records.
Document 10: Kosmos 57: Kosmos 57 was an unmanned Soviet Spacecraft launched on 22 February 1965. The craft was essentially an unmanned version of Voskhod 2. Its primary mission was to test the Volga airlock. The test was successful, but the craft was lost shortly after. The Spaceflight is designated under the Kosmos system, placed with many other Soviet scientific and military satellites.
Document 11: Berkut spacesuit: The Berkut (Russian Беркут, meaning "golden eagle") is a space suit model developed to be used for extravehicular activity for the Voskhod 2 mission aboard a Voskhod spacecraft on the first spacewalk. It was developed by NPP Zvezda in 1964-1965. It was a modified SK-1 suit. It was only used by the Voskhod 2 crew.
Document 12: Ivan Bella: Ivan Bella (born 25 May 1964 in Brezno, Czechoslovakia (now Slovakia)) is a Slovak Air Force officer who became the first Slovak citizen to fly in space. He participated in an eight-day joint Russian-French-Slovak mission to the Mir space station in 1999.
Document 13: Alexey Leonov: Alexey Arkhipovich Leonov (Russian: Алексе́й Архи́пович Лео́нов ; ] ; born 30 May 1934 in Listvyanka, West Siberian Krai, Soviet Union) is a retired Soviet/Russian cosmonaut, Air Force Major general, writer and artist. On 18 March 1965, he became the first human to conduct extravehicular activity (EVA), exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk.
Document 14: Voskhod 2: Voskhod 2 (Russian: Восход-2 )(English: Sunrise-2) was a Soviet manned space mission in March 1965. The Vostok-based Voskhod 3KD spacecraft with two crew members on board, Pavel Belyayev and Alexey Leonov, was equipped with an inflatable airlock. It established another milestone in space exploration when Alexey Leonov became the first person to leave the spacecraft in a specialized spacesuit to conduct a 12 minute "spacewalk".
Document 15: Soviet space program: The Soviet space program (Russian: Космическая программа СССР, "Kosmicheskaya programma SSSR") comprised the rocketry and space exploration programs conducted by the former Soviet Union (USSR) from the 1930s until its dissolution in 1991. Over its sixty-year history, this primarily classified military program was responsible for a number of pioneering accomplishments in space flight, including the first intercontinental ballistic missile (R-7), first satellite (Sputnik 1), first animal in Earth orbit (the dog Laika on Sputnik 2), first human in space and Earth orbit (cosmonaut Yuri Gagarin on Vostok 1), first woman in space and Earth orbit (cosmonaut Valentina Tereshkova on Vostok 6), first spacewalk (cosmonaut Alexey Leonov on Voskhod 2), first Moon impact ("Luna 2"), first image of the far side of the moon ("Luna 3") and unmanned lunar soft landing ("Luna 9"), first space rover ("Lunokhod 1"), first sample of lunar soil automatically extracted and brought to Earth ("Luna 16"), and first space station (Salyut 1). Further notable records included the first interplanetary probes: Venera 1 and Mars 1 to fly by Venus and Mars, respectively, Venera 3 and Mars 2 to impact the respective planet surface, and Venera 7 and Mars 3 to make soft landings on these planets.
