full_context: Document 1: Tim Peake: Major Timothy Nigel "Tim" Peake CMG (born 7 April 1972) is a British Army Air Corps officer, European Space Agency astronaut and a former International Space Station (ISS) crew member.
Document 2: Soyuz 18: Soyuz 18 (Russian: Союз 18 , "Union 18") was a 1975 Soviet manned mission to Salyut 4, the second and final crew to man the space station. Pyotr Klimuk and Vitali Sevastyanov set a new Soviet space endurance record of 63 days and the mark for most people in space simultaneously (seven) was tied during the mission.
Document 3: Sigmund Jähn: Sigmund Werner Paul Jähn (born 13 February 1937) is a German cosmonaut and pilot, who in 1978 became the first East German (and German native) to fly in space as part of the Soviet Union's Interkosmos programme.
Document 4: Samantha Cristoforetti: Samantha Cristoforetti (] ; born 26 April 1977 in Milan) is an Italian European Space Agency astronaut, Italian Air Force pilot and engineer. She holds the record for the longest uninterrupted spaceflight of a European astronaut (199 days, 16 hours), and until June 2017 held the record for the longest single space flight by a woman until this was broken by Peggy Whitson. She is also the first Italian woman in space. Samantha Cristoforetti is also known as the first person who brewed an espresso coffee in space.
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: Paolo Nespoli: Paolo Angelo Nespoli (Milan, 6 April 1957) is an Italian astronaut and engineer. In 2007, he first traveled into space aboard the Space Shuttle Discovery as a mission specialist of STS-120. In December 2010 he again traveled into space aboard the Soyuz TMA-20 spacecraft as an Expedition 26/27 flight engineer.
Document 7: ISSpresso: ISSpresso is the first espresso coffee machine designed for use in space, produced for the International Space Station by Argotec and Lavazza in a public-private partnership with the Italian Space Agency (ASI). The first espresso coffee was drunk in space by astronaut Samantha Cristoforetti on 3 May 2015. ISSpresso is one of nine experiments selected by the Italian Space Agency for the Futura mission.
Document 8: Vladimir Komarov: Vladimir Mikhaylovich Komarov (Russian: Влади́мир Миха́йлович Комаро́в ; ] ; 16 March 192724 April 1967) was a Soviet test pilot, aerospace engineer and cosmonaut.

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 9: European Astronaut Corps: The European Astronaut Corps is a unit of the European Space Agency (ESA) that selects, trains, and provides astronauts as crew members on U.S. and Russian space missions. As of Nov 2014, 24 ESA astronauts are now able to go board the ISS. There are currently 47 members of the Corps, 26 currently active. The European Astronaut Corps is based at the European Astronaut Centre in Cologne, Germany. They can be assigned to various projects both in Europe (at ESTEC, for instance) or elsewhere in the world, at NASA Johnson Space Center or Star City.
Document 10: Dumitru Prunariu: Dumitru-Dorin Prunariu (] ; born 27 September 1952) is a Romanian cosmonaut. He flew in space aboard Soyuz 40 spacecraft and Salyut 6 space laboratory. He was in team with another Romanian cosmonaut called Dumitru Dediu.
Document 11: Luca Parmitano: Luca Parmitano (born 27 September 1976 in Paternò, Sicily) is an Italian engineer and astronaut in the European Astronaut Corps for the European Space Agency (ESA).
