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

Context paragraphs:
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.

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.

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.

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".

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.

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.

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.

Irina Solovyova: Irina Bayanovna Solovyova (Russian: Ирина Баяновна Соловьева ) (born September 6, 1937) was one of the five women chosen in the female group, now a retired Soviet cosmonaut.  She never flew into space, but was chosen as the backup to Valentina Tereshkova, the first woman in space via Vostok 6 in June, 1963.  Solovyova was also chosen to fly on Voskhod 5, in which she would have become the first woman to walk in space (that honor went to Svetlana Savitskaya in 1984), but the Voskhod program was canceled after Voskhod 2 in favor of the Soyuz program.

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.

Pete Conrad: Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999), (Captain, USN), was an American NASA astronaut, naval officer and aviator, test pilot, and during the Apollo 12 mission became the third man to walk on the Moon.  He set an eight-day space endurance record along with his Command Pilot Gordon Cooper on the Gemini 5 mission, and commanded the Gemini 11 mission.  After Apollo, he commanded the Skylab 2 mission (the first manned one), on which he and his crewmates repaired significant launch damage to the Skylab space station.  For this, President Jimmy Carter awarded him the Congressional Space Medal of Honor in 1978.
