Alexander Gerst (born 3 May 1976 in Künzelsau, Baden-Württemberg) is a German European Space Agency astronaut and geophysicist, who was selected in 2009 to take part in space training. He was part of the International Space Station Expedition 40 and 41 from May to November 2014. Gerst returned to space on June 6, 2018, as part of Expedition 56/57. He was the Commander of the International Space Station. Alexander returned to Earth on December 20, 2018.[1] Upon the end of his second mission, he holds the most time in space than any active ESA astronaut (362 days), succeeding Italian astronaut Paolo Nespoli, and German ESA astronaut Thomas Reiter, who formally held the record for the longest time in space for any active or retired ESA astronaut.

Education and researchEdit

Gerst graduated from the Technical High School in Öhringen, Germany, in 1995. While in high school, he volunteered as a scout leader, firefighter, and water rescue lifeguard.[2]

Gerst studied at the University of Karlsruhe (now Karlsruhe Institute of Technology), Germany, where he received a degree in geophysics with distinction.[2]

From 1998 to 2003 Gerst participated in several international scientific collaborations and field experiments, including some in remote locations such as Antarctica.[2]

From 2001 to 2003, Gerst studied for a master's degree in earth sciences at Victoria University of Wellington in New Zealand. While researching his master's thesis, he developed volcano monitoring techniques that might improve forecasts of volcanic eruptions. His results were published in Science Magazine.[3]

Gerst worked as a researcher at the Institute of Geophysics[where?] between 2004 and 2009, and received his doctorate in natural sciences from the University of Hamburg in 2010, with a dissertation on geophysics and volcanic eruption dynamics.

In 2007 Gerst received the Bernd Rendel award for outstanding research from the German Research Foundation (DFG).[4]. He has published several papers, including one in Nature.[5]

In ESAEdit

Gerst was selected as an astronaut in 2009 by the European Space Agency.[6]

Expedition 40/41Edit

He visited space as part of the Expedition 40/41 International Space Station crew from May to November 2014.[7][8] On 7 October 2014, Gerst performed his first extravehicular activity (EVA) with Reid Wiseman. The astronauts moved a failed cooling pump from temporary to long-term storage on the station's truss. They also installed a new relay system that will provide backup power options to the mobile transporter, which moves the large robotic arm around the out outside of the space station. The duration of the EVA was 6 hours and 13 minutes.[9]

On 10 November 2014, he landed on Earth in the same Soyuz TMA-13M spacecraft that flew him to the International Space Station on 28 May along with Russian commander Maxim Suraev and NASA astronaut Reid Wiseman.

Gerst's six-month mission to the ISS was named "Blue Dot"[10]. The mission's name is reminiscent of Carl Sagan's description of Earth as a Pale Blue Dot as seen on a photograph taken by NASA's Voyager mission.

The mission experiments included experiments in physical science, biology, human physiology, radiation research, and technology demonstrations. Educational outreach included educational videos as part of the "flying classroom" and set of experiments performed in microgravity.[11][12]

Expedition 56/57Edit

Gerst launched his second tour to the ISS on Soyuz MS-09 on 6 June 2018, as part of Expedition 56/57. He is the commander of the ISS for Expedition 57.[13][14] He will bring a robot assistant called "CIMON".[15] He was the second European Space Agency astronaut to command the station, after Frank de Winne commanded Expedition 21, and also the youngest astronaut to command the station, at age 42 as of October 2018. In May 2017, his mission name and logo were announced, called "Horizons".[9]. On 20 December 2018 he and his crewmates Serena Aunon-Chancellor and Sergey Prokopyev returned to Earth and landed in Kazakhstan after 197 days in space, combined with the 165 days in space on his last mission, Gerst has 362 days in space, more than any other ESA astronaut in history[16].

Personal lifeEdit

Gerst is single, and in his spare time he enjoys mountaineering, diving, climbing and skydiving.[17]

Gerst is a licensed radio amateur (KF5ONO) and has participated in several ARISS (Amateur Radio on the International Space Station) educational contacts.[18]

In popular cultureEdit

Some of Gerst's background and appearance is incorporated into the character of Alex Vogel, a German astronaut and part of the crew of the Hermes vessel in the 2015 science-fiction film The Martian.[19]
