Mobile telephones, high-speed Internet, up-to-date meteorological data and navigation programs available anytime, anywhere – all thanks to satellites. Bandwidth and frequencies that are revised every three to four years at the World Radiocommunication Conference play an important role in this.
Indonesia is on fire – the island state is currently facing a bitter struggle against forest and peat fires on Sumatra and Borneo, most likely caused by illegal 'slash and burn' farming to clear the land for palm oil or timber plantations. The extremely dry conditions resulting from the El Niño weather phenomenon exacerbate this problem.
The students cheered – the DECAN (Deutsche CanSat Höhenrakete) research rocket took off from the Esrange Space Center in north Sweden at 02:53 on 27 October 2015 and proceeded to reach an altitude of roughly 5.5 kilometres. The rocket was designed, built and launched by a team of students from Technische Universität Berlin (TU Berlin) as part of the new STERN (Studentische Experimental-Raketen) German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) programme.
Alternative fuels have the potential to support the environment- and climate-friendly developments in air transport. At present, global air traffic contributes towards almost five percent of global warming. In addition to the greenhouse gas carbon dioxide, condensation trails and the resulting cirrus clouds lead to a significant climate impact.
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.
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.
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.
Whoever wants a glimpse of the future of our climate has to cast his eyes upward. Almost into outer space, up some 100 kilometres, at night. Then the consequences of global warming become rapidly evident. For years the German Aerospace Center (DLR) has been monitoring the temperature of the atmosphere at this altitude and analysing the changes—in order to improve climate models and to detect natural disasters early, like flooding, earthquakes and tsunami. The "base camp" for measurements is Germany‘s highest research station, the Schneefernerhaus Environmental Research Station (UFS) on Zugspitze mountain.
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.
The International Space Station (ISS) offers a unique opportunity to conduct research in microgravity. Its newest research system – the PK-4 plasma crystal laboratory – has now begun scientific operations in the Columbus module.
