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.
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.
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.
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 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.
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.
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.
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.
