context_page_description: Johann-Dietrich "Jan" Wörner, born 18 July 1954 in Kassel, is a German civil engineer, university professor and former president of Technische Universität Darmstadt. He served as chairman of the executive board of the German Aerospace Center DLR from 1 March 2007 to 30 June 2015. On 1 July 2015, he succeeded Jean-Jacques Dordain as Director General of the European Space Agency.
context_section_description: Until 1990, Wörner worked for the engineering office König und Heunisch in Frankfurt. In the same year, he was appointed professor for solid construction and head of the testing and research institute at TH Darmstadt. He founded his own engineering office Wörner und Partner in 1994. From 1992 to 1994 Wörner served as dean of the university's civil engineering department. Starting in 1993, he also held the office of technical director at the Gelsenkirchen institute for glass construction. Wörner was appointed a test engineer for structural analysis and solid construction in 1994 and a professor of structural engineering in 1995.
  On 28 June 1995, Wörner was elected president by the assembly of what was then called the TH Darmstadt and lead the University from 24 July 1995 to 28 February 2007.
  Wörner was elected deputy speaker for Universities in the German Rectors' Conference in 2002. In 2003, he became speaker of ARGE TU/TH, the technical universities and technological institutes working group. In 2003 he joined the science council's Ranking working group and assumed the chair for structural analysis for superstructures at the University's architecture department as a provisional substitute. In 2004, he joined the science council's Universities working group.
  Between 2010 and 2011, Wörner served on the High-Level Group on Aviation and Aeronautics Research launched by European Commissioners Siim Kallas and Máire Geoghegan-Quinn. In February 2011, the State Government of Baden-Württemberg appointed him to serve as a mediator for the controversial railroad infrastructure project Stuttgart 21, after he had already mediated talks concerning airport constructions in Frankfurt.
  On 18 December 2014, the European Space Agency announced that Wörner would assume the office of director general for four years on 1 July 2015.
  On 19 October 2016 Wörner claimed that the despite the crash at the attempted landing, the Schiaparelli mission was still a success from an engineering standpoint because of the data gathered. Not only was the parachute released early, but moreover the retrorockets fired for only 3s rather than the required 30s. The probe crashed into the surface at 300 km per hour, leaving a 40m wide impact site.
  In 2015, Wörner has proposed cooperation among countries and companies on lunar capabilities, a concept referred to as Moon Village.
