Philae was more than 500 million kilometres from Earth when it touched down on Comet 67P/Churyumov-Gerasimenko one year ago, on 12 November 2014. "We looked after and planned this mission for almost 20 years and launched the Rosetta orbiter and Philae lander on their journey through space – so landing day really was quite special," says Philae Project Manager Stephan Ulamec from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) to sum up the mood on the day.
NORAH (NOise-Related Annoyance, cognition, and Health) is the largest European-level study on the effects of air, road and rail traffic noise. The results have recently been released by the Environment and Community Centre (Umwelt- und Nachbarschaftshaus), a subsidiary of the German state of Hesse and part of the Forum Airport and Region (Forum Flughafen und Region).
Over 60,000 guests visited the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Cologne-Porz site on 20 September 2015 for German Aerospace Day. DLR and the European Space Agency (ESA), together with their partners, exhibited current research projects and missions in the fields of aeronautics, space, energy, transport and security.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is opening its doors to their laboratories and institutes on German Aerospace Day, offering visitors an insight into the ongoing research. Teaming up with the event partners – the European Space Agency (ESA), Cologne Bonn Airport and the German Air Force – DLR will showcase a major aircraft exhibition alongside the astronaut training facilities in the EAC (European Astronaut Center).
For the next few weeks, the German Aerospace Center (DLR) :envihab research facility will be home to 12 men in good health, aged between 20 and 45 years. The men are test subjects for a long-term bedrest study – they will be confined to bedrest for two months with two weeks of experimental investigations and tests. Their beds will be tilted at an angle of six degrees below the horizontal, so that their bodily fluids shift towards the upper body; the bones and muscles in their lower part of their bodies will lose strength as a result of the lack of movement. “In this way we simulate the effects of microgravity on the human body,” says Edwin Mulder, leader of the study and a scientist at the DLR Institute of Aerospace Medicine, about the study, which is being carried out by DLR on behalf of the European Space Agency (ESA). “Our volunteers are, so to speak, terrestrial astronauts.” Half of the test subjects will undergo reactive jump training several times a week, which involves lying on a specially positioned training device. “We want to see whether this very intensive training can be an effective countermeasure to the deterioration of the bones and muscles.”
On 20 September 2015, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and its partners, the European Space Agency (ESA), Cologne/Bonn Airport and the German Air Force, will be hosting German Aerospace Day (Tag der Luft- und Raumfahrt) in Cologne. On the day, DLR researchers will open the doors to their institutes and laboratories and allow the public to take a look at their work. There will also be a major aircraft exhibition, where visitors will be able to see DLR's unique research aircraft, German Air Force aircraft and an Emirates Airbus A380.
For weeks, comet Churyumov-Gerasimenko has been active, hurling dust and gas into space – but it will not reach the closest point to the Sun in its orbit, the perihelion, until 13 August 2015 at exactly 4:03 CEST. It will take another six-and-a-half years to get this close to the Sun once again.
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.
