Claude Nicollier (born 2 September 1944 in Vevey, Switzerland) is the first astronaut from Switzerland.
 He has flown on four Space Shuttle missions.
 His first spaceflight (STS-46) was in 1992, and his final spaceflight (STS-103) was in 1999.
 He took part in two servicing missions to the Hubble Space Telescope (called STS-61 and STS-103).
 During his final spaceflight he participated in a spacewalk, becoming the first European Space Agency astronaut to do so during a Space Shuttle mission (previous ESA astronauts conducted spacewalks aboard "Mir", see List of spacewalks and moonwalks 1965–1999).
 In 2000 he was assigned to the Astronaut Office Extravehicular Activity Branch, while maintaining a position as Lead ESA Astronaut in Houston.
 Nicollier retired from ESA in April 2007.
Frank, Viscount De Winne (born 25 April 1961, in Ledeberg, Belgium) is a Belgian Air Component officer and an ESA astronaut.
 He is Belgium's second person in space (after Dirk Frimout).
 He was the first ESA astronaut to command a space mission when he served as commander of ISS Expedition 21.
 ESA astronaut de Winne serves currently as Head of the European Astronaut Centre of the European Space Agency in Cologne/Germany (Köln).
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.
Roberto Vittori (born 15 October 1964 in Viterbo) is an Italian air force officer and an ESA astronaut.
 After graduating from the Italian Accademia Aeronautica in 1989, Vittori flew in the Italian Air Force.
 He then trained as a test pilot in the United States.
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.
Michel Ange-Charles Tognini (born September 30, 1949 in Vincennes, France) is a French test pilot, Brigadier General in the French Air Force, and a former CNES and ESA astronaut who serves from 01.01.2005 to 01.11.2011 as Head of the European Astronaut Centre of the European Space Agency.
 A veteran of two space flights, Tognini has logged a total of 19 days in space.
 Tognini has 4000 flight hours on 80 types of aircraft (mainly fighter aircraft including the MiG-25, Tupolev 154, Lightning MK-3 and MK-5, Gloster Meteor, and F-104).
 He is fluent in English and Russian.
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.
The European Astronaut Centre (EAC) (German: Das Europäische Astronautenzentrum, French: Centre des astronautes européens; CAE), is a centre of the European Space Agency and home of the European Astronaut Corps.
 It is located in Cologne, Germany, and is subdivided into four separate arms, these being Training, Medicine, Education and PR, and Astronaut Management.
 It provides training facilities to the European astronauts (including a neutral buoyancy pool), particularly regarding ESA hardware for the ISS such as Columbus and the ATV.
 The overall European Astronaut Centre organisation is also in charge of the organisation of the training of European astronauts in the centers of other partners, such as the United States (Johnson Space Center), Russia (Star City), Canada (Saint-Hubert) or Japan (Tsukuba).
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).
 The astronauts work on missions at the International Space Station.
 He was selected as an ESA astronaut in May 2009.
CAVES, an acronym for Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills, is a European Space Agency astronaut training course in which international astronauts train in a space-analogue cave environment.
 The course is designed at the European Astronaut Center to prepare astronauts for safe and efficient long duration spaceflight operations by means of a realistic scientific and exploration mission within a multicultural, ISS-representative team.
