Question: What year did the cosmonaut that manned Vostok 4 die?

Context paragraphs:
Cosmonautics Day: Cosmonautics Day (Russian: День Космона́втики , "Den Kosmonavtiki") is an anniversary celebrated in Russia and some other former USSR countries on 12 April.  In Poland an "International Day of Aviation and Cosmonautics" (Polish: "Międzynarodowy Dzień Lotnictwa i Kosmonautyki" ) is celebrated on the same day.  In 2011, 12 April was declared as the International Day of Human Space Flight in dedication of the first manned space flight made on 12 April 1961 by the 27-year-old Russian Soviet cosmonaut Yuri Gagarin.  Gagarin circled the Earth for 1 hour and 48 minutes aboard the Vostok 1 spacecraft.

Mercury-Atlas 8: Mercury-Atlas 8 (MA-8) was the fifth United States manned space mission, part of NASA's Mercury program.  Astronaut Walter M. Schirra Jr., orbited the Earth six times in the Sigma 7 spacecraft on October 3, 1962, in a nine-hour flight focused mainly on technical evaluation rather than on scientific experimentation.  This was the longest U.S. manned orbital flight yet achieved in the Space Race, though well behind the several-day record set by the Soviet Vostok 3 earlier in the year.  It confirmed the Mercury spacecraft's durability ahead of the one-day Mercury-Atlas 9 mission that followed in 1963.

Vostok 2: Vostok 2 (Russian: Восток-2 , "Orient 2" or "East 2") was a Soviet space mission which carried cosmonaut Gherman Titov into orbit for a full day on August 6, 1961 to study the effects of a more prolonged period of weightlessness on the human body.  Titov orbited the Earth over 17 times, exceeding the single orbit of Yuri Gagarin on Vostok 1 − as well as the suborbital spaceflights of American astronauts Alan Shepard and Gus Grissom aboard their respective Mercury-Redstone 3 and 4 missions.  Indeed, Titov's number of orbits and flight time would not be surpassed by an American astronaut until Gordon Cooper's Mercury-Atlas 9 spaceflight in May 1963.

Vostok 1: Vostok 1 (Russian: Восто́к , "East" or "Orient" 1) was the first spaceflight of the Vostok programme and the first manned spaceflight in history.  The Vostok 3KA space capsule was launched from Baikonur Cosmodrome on April 12, 1961, with Soviet cosmonaut Yuri Gagarin aboard, making him the first human to cross into outer space.

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.

Valery Bykovsky: Valery Fyodorovich Bykovsky (Russian: Вале́рий Фёдорович Быко́вский ; born 2 August 1934) is a retired Soviet cosmonaut who flew three manned space mission space flights: Vostok 5, Soyuz 22, and Soyuz 31.  He was also backup for Vostok 3 and Soyuz 37.

Pavel Popovich: Pavel Romanovich Popovich (Russian: Па́вел Рома́нович Попо́вич , Ukrainian: Павло Романович Попович , Pavlo Romanovych Popovych) (October 5, 1930 – September 29, 2009) was a Soviet cosmonaut.

Vostok 5: Vostok 5 (Russian: Восток-5 , "Orient 5" or "East 5") was a joint mission of the Soviet space program together with Vostok 6; as with the previous pair of Vostok 3 and Vostok 4 the two Vostok spacecraft came close to one another in orbit and established a radio link.

Vostok 4: Vostok 4 (Russian: Восток-4 , "Orient 4" or "East 4") was a mission in the Soviet space program.  It was launched a day after Vostok 3 with cosmonaut Pavel Popovich on board—the first time that more than one manned spacecraft were in orbit at the same time.  The two Vostok capsules came within 6.5 km of one another and ship-to-ship radio contact was established.

Foton (satellite): Foton (or Photon) is the project name of two series of Russian science satellite and reentry vehicle programs.  Although unmanned, the design was adapted from the manned Vostok spacecraft capsule.  The primary focus of the Foton project is materials science research, but some missions have also carried experiments for other fields of research including biology.  The original Foton series included 12 launches from the Plesetsk Cosmodrome from 1985 to 1999.  The second series, under the name Foton-M, incorporates many design improvements over the original Foton, and is still in use.  So far, there have been four launch attempts of the Foton-M.  The first was in 2002 from the Plesetsk Cosmodrome, which ended in failure due to a problem in the launch vehicle.  The last three were from the Baikonur Cosmodrome, in 2005, 2007, and 2014; all were successful.  Both the Foton and Foton-M series used Soyuz-U (11A511U and 11A511U2) rockets as launch vehicles.  Starting with the Foton-7 mission, the European Space Agency has been a partner in the Foton program.
