DLR has its headquarters in Cologne. The site is located next to Cologne-Bonn airport. Approximately 1,500 employees work in the institutes and facilities and in the central administration.
On 12 November 2014, as the Philae lander slowly descended onto Comet 67P/Churyumov-Gerasimenko, the first instruments on board began to take measurements. Philae touched down three times during the first ever landing on a comet, scraped against a crater rim, and finally arrived at the unforeseen landing site, called Abydos, at 18:31 CEST.
On 9 July 2015 at 19:45 CEST, Philae reported back to the team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center (LCC) – only to then go back to 'silent mode'. Since then, the team has been working hard to get back in contact with the lander and operate it to conduct scientific measurements.
The Philae lander communicated with the Rosetta orbiter again between 19:45 and 20:07 CEST on 9 July 2015 and transmitted measurement data from the COmet Nucleus Sounding Experiment by Radiowave Transmission (CONSERT) instrument. Although the connection failed repeatedly after that, it remained completely stable for those 12 minutes.
Collaboration between them is already a reality, but with the signing of a framework cooperation agreement on 9 July 2015, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the National Research Council of Canada (NRC) have now strengthened their cooperation. Current research projects will be extended in the next five years – for example, in the area of alternative aircraft fuels – and new cooperation projects will be embarked upon to facilitate, among other things, uncrewed aerial vehicles (UAV) and aircraft cabin research.
