Aviation and the impact it can have on the climate can be integrated into international climate protection protocols. This would enable significant reductions in climate-related emissions and associated impact, with a modest effect on the demand for air transport.
White patches on the dwarf planet Ceres have fascinated scientists since their discovery. Now, the Dawn orbiter has transmitted new images looking vertically down on to the dwarf planet's north pole, showing two unusual patches clearly distinct from their darker surroundings.
Comets eject gas and dust into space. Primarily, this takes place on the areas of the comet's surface exposed to direct sunlight. In mid-March, from a distance of 75 kilometres, the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on board the Rosetta orbiter acquired images of an extraordinary phenomenon occurring on Comet 67P/Churyumov-Gerasimenko.
Sierra Nevada Corporation (SNC's) Space Systems and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) announce the signing of a new Dream Chaser® cooperation during the U.S. German Aerospace Roundtable (UGART) at the 31st annual Space Symposium hosted by the Space Foundation in Colorado Springs, Colorado.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is organising the 36th International Symposium on Remote Sensing of the Environment (ISRSE) in Berlin from 11 to 15 May 2015.
Previously, images of Mars were available in strip format – strip by strip carefully flown with the European Mars Express spacecraft and processed into three-dimensional terrain models and perspective images. Now, planetary scientists, under the leadership of the German Aerospace Center (DLR) have, for the first time, joined these individual 50 to 100 kilometre wide strips to create a single large-scale map.
Although from 28 March 2015, following difficulties with its star trackers and navigation system, the Rosetta orbiter is now following a new and more distant trajectory around Comet 67P/Churyumov-Gerasimenko, the team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center (LCC) will begin listening again for signals from the Philae lander at 02:00 CET on 12 April 2015.
Batteries and fuel cells for the vehicles of tomorrow, solar thermal power plants, heat storage and smart rotor blades for wind turbines – there are plenty of opportunities to make the energy supply of the future clean and sustainable.
Perhaps it is still too cold for the Philae lander to wake up on Comet 67P/Churyumov-Gerasimenko. Maybe its power resources are not yet sufficient to send a signal to the team at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Lander Control Center.
The environmental conditions on board the International Space Station ISS are strictly controlled; there are only very slight variations in temperature, humidity, air pressure and light intensity.
This Friday, 20 March, will see the rare event of a solar eclipse. The Sun will not be completely covered in Germany and central Europe; the total solar eclipse will only be visible in the Arctic Ocean.
It would be very lucky if a signal were to be received from Rosetta's Philae lander at 05:00 CET on 12 March 2015. The lander finally came to rest in a rather shaded location on Comet 67P/Churyumov-Gerasimenko and it needs to receive sufficient energy before it can wake up and begin communicating.
NASA's Dawn spacecraft entered orbit around the dwarf planet Ceres on 6 March 2015 at 13:39 CET. In order for Dawn to be captured by Ceres' gravitational field, the spacecraft started using its ion engines from a distance of 61,000 km to slow the spacecraft down.
On 14 February 2015, the Optical, Spectroscopic and Infrared Remote Imaging System (OSIRIS) on the Rosetta spacecraft observed the surface of comet 67P Churyumov-Gerasimenko with the Sun directly behind it, so the only shadow seen in the image is that of the photographer, the orbiter itself.
It is only a few more days until the Dawn spacecraft enters orbit around Ceres on 6 March 2015, marking humankind's first visit to a dwarf planet. What Ceres has disclosed to scientists so far has raised more questions than it has provided answers.
The large blades of the fan dominate when looking at an aircraft engine from the front. They are also among the largest producers of in-flight noise. Researchers conducting trials at the German Aerospace Center (DLR) have now succeeded in demonstrating, for the first time anywhere in the world, that fan noise can be reduced substantially by introducing compressed air.
Only 46,000 kilometres separated the Dawn spacecraft from its destination, the dwarf planet Ceres, when its German-built Framing Camera acquired the latest images on 19 February 2015. One of the most striking features of Ceres is the multitude of different crater shapes across its surface; in addition to numerous smaller, shallow craters, the images also reveal impact basins with large mountains located at their centres.
The final farewell; Georges Lemaître, the fifth and last European Automated Transfer Vehicle (ATV) performed a controlled re-entry into Earth’s atmosphere and burned up at around 19:00 CET on 15 February. Its task had been to transport supplies and experiments to the International Space Station (ISS) and to raise and adjust the International Space Station ISS orbit. The era of ATV space transporters has now drawn to a close with its retirement from service – but the expertise gained during their development and operation will live on as part of the European service module fitted to the United States Orion space capsule.
Comet 67P/Churyumov-Gerasimenko could lose up to 20 metres of surface material from its previously unilluminated south side when it heats up, starting in May 2015. The increasing heat as the comet approaches the Sun will trigger this 'diet', during which gases and solid materials will be ejected into space.
Without water, there can be no life as we know it. This principle applies both to Earth and to other celestial bodies. Water that has been lying hidden under a thick sheet of ice for millions of years can tell us something about the origin and development of life. But if one wants to recover a sample of this water, care has to be taken that no microorganisms from the surface are introduced and that the sample and underwater habitat are not contaminated.
