Earth Observation 2.0 – how satellite data reveal our Blue Planet

16. April 2015

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.

Mars

Mars in large format

14. April 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.

Total solar eclipse in the Arctic, visible as a partial eclipse in Germany

18. March 2015

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.

Region nahe von Cydonia Mensae auf der nördlichen Halbkugel des Mars

The Cydonia region – was the north of Mars once covered by an ocean?

12. March 2015

These images, acquired by the High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board ESA’s Mars Express spacecraft, show a region close to Cydonia Mensae in the northern hemisphere of Mars.

Ceres

Dawn in orbit around icy Ceres

6. March 2015

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.

Lots of light and little shadow on 67P Churyumov-Gerasimenko

3. March 2015

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.

Ceres

Dawn orbiter nears the finishing line

2. March 2015

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.

High-pressure air fights aircraft noise – compressed air substantially reduces engine noise

27. February 2015

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.

Ceres

Promising crater-strewn landscape on dwarf planet Ceres

25. February 2015

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.

Metamorphosed by climate change – the southern area of Phlegra Montes

19. February 2015

The mountain massif of Phlegra Montes extends into the northern lowlands of Mars like a long, slightly curved salient. Stretching for hundreds of kilometres, this alignment of numerous mountains, rolling hills and ridges lies to the east of the volcano Hecates Tholus in the Elysium volcanic region.
