Ceres – unusual landslides and unstable crater walls

25. August 2015

The lower the Dawn space probe flies over the dwarf planet Ceres with its on-board camera, the more puzzling – and exciting – the celestial body appears. “Some of the things we are seeing have never been seen anywhere else in the Solar System,” says Ralf Jaumann from the German Aerospace Center (DLR). “Except for on Earth.” Dawn is now looking down onto the surface of Ceres from an altitude of just 1470 kilometres. The first images acquired from its High Altitude Mapping Orbit (HAMO) show a ‘pyramid’ with unusual landslides, unstable crater walls and chains of mountains. “We can only speculate about these things at the moment.” Where the bright stripes along the pyramid-shaped mountain come from and whether the surface of the dwarf planet is comprised of different materials are questions that the planetary researchers are still trying to answer.

DLR at MAKS 2015 in Moscow

25. August 2015

The International Aviation and Space Salon MAKS 2015 is being held in Zhukovsky, near Moscow, from 25 to 30 August 2015. This is the sixth time that the German Aerospace Center (DLR) is exhibiting at the biennial Russian aerospace exhibition. With an exhibition space of 100 square metres, DLR will be presenting its concepts and technologies for the space and aeronautics of tomorrow. DLR satellite technology is the main focus of the exhibit.

Kontur-2 – Controlling robots remotely from space

19. August 2015

Although only about 400 kilometres separate the Kontur-2 joystick and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) ROKVISS robot, the remote control operations that took place on 18 August 2015 were truly special: Cosmonaut Oleg Kononenko, flying aboard the International Space Station (ISS) over Earth at 28,000 kilometres per hour, controlled the robot on the ground while in microgravity. The connection between space and Earth is not one-directional – the ROKVISS (Robotic Components Verification on the ISS) sends data back to the joystick when contact forces occur on the ground. At 16:37 CEST (ISS orbit 3775), the metal fingers of the robot moved for the first time – controlled remotely from space. “At that moment, Kononenko not only saw what was happening using a camera, but, through the joystick, felt exactly what was happening with the robot in our laboratory,” says Jordi Artigas from the DLR Institute of Robotics and Mechatronics. In autumn 2015 the first ‘tele-handshake’ will be performed between the ISS and Earth with this technology, when the DLR Robot ‘Space Justin’ remotely shakes hands with someone on Earth from space – with force feedback.

Pascale Ehrenfreund ist neue Vorstandsvorsitzende des DLR

Pascale Ehrenfreund – the new Chair of the DLR Executive Board

17. August 2015

Pascale Ehrenfreund took office as Chair of the Executive Board at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on 17 August 2015. This places her at the head of one of Europe’s largest research institutes and its 8000 employees.

A virtual flight over Atlantis Chaos on board Mars Express

3. August 2015

Countless myths have been woven around the legendary realm of Atlantis. Circa 350 BC, the philosopher Plato depicted a maritime power situated in Atlantis that controlled broad areas of Europe and Africa. It was most likely an island whose inhabitants ruled over the people living in the multiple regions bordering the Mediterranean.

Churyumov-Gerasimenko: Almost like firn and shaped by 'hail'

30. July 2015

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.

Fertility deities on dwarf planet Ceres

28. July 2015

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.

KONTUR-2 – remote control in space

22. July 2015

The new crew on their way to the International Space Station (ISS) – cosmonaut Oleg Kononenko and astronauts Kimiya Yui and Kjell Lindgren – will be carrying a compact piece of luggage on board the Soyuz spacecraft. The KONTUR-2 joystick developed by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is setting off to its new destination. Upon arrival, Kononenko will be responsible for working with the device and in August will operate the ROKVISS (Robotic Components Verification on the ISS) robot installed at the DLR Robotics and Mechatronics Center using the remote control. What makes this special? The cosmonaut will not only see a camera image of the robot sent up from the ground, he will also, at a distance of over 400 kilometres, feel precisely what the robot back on Earth touches. This is enabled by a mechanism in KONTUR-2 that detects exactly how strongly it touches another object, as well as other metrics. The telepresence experiment is designed to give its operator the impression of being on-site at the laboratory – and not in orbit around Earth.

Headache for Philae

20. July 2015

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.

DLR/NASA – 3D radar measurements of forest areas

15. July 2015

A tangle of treetops and branches, through which just the occasional clear area provides glimpses of the trunks and roots growing below. Whether it is woodland with German spruces or a tropical rainforest, very few sensors are able to see through this green carpet and clearly visualise the underlying structures. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is developing radar technology that, for the first time, will enable a three-dimensional visual representation of forest areas from the roots to the crowns.
