Akihiko Hoshide (星出 彰彦, Hoshide Akihiko, born December 28, 1968) is a Japanese engineer and JAXA astronaut. On August 30, 2012, Hoshide became the third Japanese astronaut to walk in space.[1]

Early life and education[edit]

He was born in 1968 in Tokyo, Japan.[2]

He received an International Baccalaureate Diploma from the United World College of South East Asia in 1987, a bachelor's degree in Mechanical Engineering from Keio University in 1992, and a Master of Science degree in Aerospace Engineering from the University of Houston Cullen College of Engineering in 1997.


Hoshide joined the National Space Development Agency of Japan (NASDA) in 1992 and worked in the development of the H-II launch vehicle for two years. From 1994 to 1999, he was as an astronaut support engineer for the NASDA Astronaut Office, supporting the development of the astronaut training program, and he supported astronaut Koichi Wakata during Wakata's training and mission on STS-72.

In February 1999 Hoshide was selected by NASDA (now JAXA) as one of three Japanese astronaut candidates for the International Space Station (ISS). He started the ISS Astronaut Basic Training program in April 1999 and was certified as an astronaut in January 2001. Since April 2001, he has participated in ISS Advanced Training, as well as supporting the development of the hardware and operation of the Japanese Experiment Module Kibō and the H-II Transfer Vehicle (HTV).

From 21 July 2014 to 29 July 2014 Hoshide commanded NASA Extreme Environment Mission Operations Mission 18 (NEEMO 18) to the Aquarius Reef Base of the coast of Key Largo, Florida. He was joined by NASA astronaut Jeanette Epps and Mark Vande Hei as well as ESA astronaut Thomas Pesquet during the nine-day mission.[3]

In 2016 he served as part of the 2016 European Space Agency's Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills (CAVES) expedition. Where he spent two weeks underground in caves alongside NASA astronauts Ricky Arnold and Jessica Meir, CNSA taikonaut Ye Guangfu, Roscosmos cosmonaut Sergei Korsakov and ESA astronaut Pedro Duque in order to simulate spaceflight conditions[4].


Hoshide's first mission was as Mission Specialist on the STS-124 mission, which was the second of three missions to deliver the Japanese Experiment Module ("Kibo") to the ISS[5]. STS-124 launched on 31 May 2008 from the Kennedy Space Center on its mission to the space station. After 14 days in space, Hoshide and the rest of the crew landed at the Kennedy Space Center on 14 June 2008.

Expedition 32/33[edit]

On 15 July 2012 Hoshide launched on his second mission[6] onboard Soyuz TMA-05M along with NASA astronaut Sunita Williams and Roscosmos cosmonaut Yuri Malenchenko.[7] The trio docked with the ISS two days later and all became Flight Engineers on Expedition 32 along with commander Gennady Padalka and Flight Engineers Joe Acaba and Sergei Revin who had transferred from Expedition 31[8]. The crew worked together until Padalka, Acaba and Revin returned to Earth on 17 September 2012[9], after witch Hoshide, Williams and Malenchenko transferred over to Expedition 33 where they were later joined by Kevin Ford, Oleg Novitskiy and Evgeny Tarelkin[10]. The Soyuz TMA-05M crew returned to Earth on 19 November 2012. During the mission, Hoshide spent 126 Days in space and completed three EVAs[11].

Expedition 64/65[edit]

In March 2018 JAXA announced that Hoshide will launch into space for the third time in May 2020, he will launch to the ISS and serve as a Flight Engineer on Expedition 64 and then Commander of Expedition 65, during the mission he is scheduled to become only the second Japanese astronaut to command the station, following Koichi Wakata who commanded Expedition 39 in 2014[12]
