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.
Acting on behalf of the NASA Dawn mission team, researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) chose 17 of approximately 150 fertility deities to name the most prominent craters on Ceres, which they presented to the International Astronomical Union (IAU). These names were chosen because the dwarf planet bears the name of the Roman goddess of agriculture.
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.
After a nine-and-a half year journey, the NASA New Horizons spacecraft will fly past the dwarf planet Pluto – approximately 4.8 billion kilometres from Earth – at 13:50 CEST on 14 July 2015. This is the first time that the former 'ninth planet' in the Solar System will receive a visitor.
At 13:28 CEST on 2 July 2015, the alarm in the Wünsdorf forest fire centre went off. Smoke had been seen rising from the forest district in Baruth. The German Meteorological Service had previously raised the risk of forest fire to the highest alert level. In the past, employees of the Brandenburg state forestry office sat in the cramped towers – 100 steps above the ground – using binoculars as they scanned the horizon for signs of forest fires during the hot summer months.
The German Aerospace Center's (Deutsches Zentrum für Luft- und Raumfahrt; DLR) mobile rocket base MORABA launched the MAPHEUS-5 high-altitude research rocket at 06:55 CEST on 30 June 2015, carrying four DLR experiments on board. The 12-metre-high, two-stage rocket took off from the Swedish Esrange Space Center and ascended to an altitude of 253 kilometres – taking only 74 seconds to reach a state of microgravity lasting over six minutes, which was used to conduct experiments from the fields of material physics and biology.
For 28 hours, six subjects will remain lying down and tilted at 12 degrees so their heads are lower than their legs. At times, they live and sleep in a carbon dioxide enriched atmosphere. With the 'SpaceCOT' study, researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and the US National Space Biomedical Research Institute (NSBRI) are investigating how the human brain and eyes are affected by the shift of body fluids towards the head as well as the increased carbon dioxide content in the air.
Despite a new trajectory for Rosetta and a reduction of the distance between the orbiter and Comet 67P/Churyumov-Gerasimenko from 200 to 180 kilometres, contact with the Philae lander remains irregular and short. After the initial contact on 13 June 2015, Philae has reported to the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center (LCC) in Cologne a total of six times.
Today, Mars appears bone-dry and dusty – but new analyses of Istok crater provide evidence of periodic flows of debris from its walls into its interior. "What is surprising is that it must have happened reasonably often," explains Ernst Hauber, a planetary researcher at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).
The team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) received data from the Philae lander for the third time on 19 June 2015. Between 15:20 and 15:39 CEST, Philae sent 185 data packets.
The Stratospheric Observatory for Infrared Astronomy (SOFIA), a joint project between the US space agency NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), started the first observation flight of this year's New Zealand campaign on 19 June 2015 at 09:20 CEST (19:20 local time).
After more than 10 years of intense development, Airbus in Friedrichshafen has completed the main component that will be at the heart of the highly sensitive payload of the LISA Pathfinder mission – the LISA Technology Package (LTP) Core Assembly.
The Philae lander reported back on 14 June 2015. From 23:22 to 23:26 CEST, the lander sent some data packets that are now being evaluated at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). "But this time, the connection to the lander was relatively unstable," says DLR Philae Lander Project Leader Stephan Ulamec.
The Philae lander has reported back on 13 June 2015 at 22:28 (CEST), coming out of hibernation and sending the first data to Earth. More than 300 data packets have been analysed by the team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center: "Philae is doing very well – it has an operating temperature of minus 35 degrees Celsius and has 24 watts of power available," explains DLR’s Philae Project Manager, Stephan Ulamec. "The lander is ready for operations." Philae 'spoke' for 85 seconds with its team on ground in its first contact since it went into hibernation.
There are just 188 known meteorite craters worldwide. Some span a mere 10 metres, while others extend across 160 kilometres and are significantly more impressive. They all share a common history – an object from outer space must hit the Earth travelling at least 11 kilometres per second, or 39,000 kilometres per hour, to leave behind an impact crater.
On 15 November 2014 at 01:15 CET, Philae's battery was exhausted and, after nearly 60 hours of operation on Comet 67P/Churyumov-Gerasimenko, the lander went into hibernation – in an unexpected place. Philae 'bounced' several times before landing in its current location, and its exact position has still not been determined.
The Dawn orbiter initially traced the path of the equator before crossing the north and south poles of Ceres. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have used the images acquired thus far with the Framing Camera on board the spacecraft and the first three-dimensional terrain models created from them to produce a virtual scenic flight over icy Ceres.
Under the catchphrase 'Knowledge for Tomorrow', the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is presenting its technological innovations in aerospace at the Paris Air Show. The 51st Air Show in Paris, one of the largest and most important aerospace exhibitions in the world, provides an exciting platform for leading representatives of the industry.
The upgraded far-infrared spectrometer upGREAT has successfully completed its first deployment on board the Stratospheric Observatory for Infrared Astronomy (SOFIA), a joint project between the US Space Agency NASA and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). During four commissioning flights from its home base in Palmdale, California, conducted between 13 and 22 May 2015, upGREAT showed unprecedented efficiency in analysing the origins of carbon radiation from interstellar gas and dust clouds.
