In 2010 the university awarded him an honorary doctorate degree. He completed his training as a pilot in Germany and Texas. Astronaut career He served as an onboard engineer for the Euromir 95/Soyuz TM-22 mission to the Mir space station. During his 179 days aboard Mir, he carried out two EVAs and became the first German astronaut to perform a spacewalk. Between 1996 and 1997, he underwent additional training on the Soyuz spacecraft and was awarded a "Soyuz Return Commander" certificate, qualifying him to command a three-person Soyuz crew during its return from space. He trained for a six-month mission to the International Space Station (ISS) and was selected for the Space Shuttle Discovery STS-121 mission to join Expedition 13. The launch was initially scheduled for 1 July 2006, but was due to weather delays eventually conducted on 4 July 2006. Discovery then departed on 15 July, leaving Reiter on the ISS continuing to work on Expedition 13. He later became part of Expedition 14 before returning to Earth, again aboard Discovery during the STS-116 mission. Reiter returned after 171 days in space, therefore having been in orbit twice, each time for almost half a year. His ISS mission was designated Astrolab by the European Space Agency. On 8 August 2007 Thomas Reiter was named a member of DLR's executive board. From 1 April 2011 to December 2015 he was Director of Human Spaceflight and Operations at the European Space Agency (ESA), responsible for all crewed and uncrewed mission operations. This included the operation and exploitation of the European International Space Station elements, ESA's Automated Transfer Vehicle, the responsibility for the European Astronaut Centre, EAC, and ESA's uncrewed missions and ground-based mission infrastructure.
