Less than 2000 kilometres separate the ESA orbiter Rosetta and the Philae lander from their destination, Comet 67P/Churyumov-Gerasimenko. Images acquired with the OSIRIS camera system already indicate what lies ahead for the orbiter and lander upon arrival: "The surface seems pretty rough. We will have to wait to determine whether the visible depressions are impact craters or structures produced by cometary activity," says Ekkehard Kührt from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). The comet researcher is involved in the acquisition of data by the OSIRIS camera and is also responsible for data analysis. Another image taken by the camera shows that a cloud of dust, the coma, enshrouds the comet. “As we draw closer to Churyumov-Gerasimenko, the other instruments used in the mission will provide us with interesting insights into the interaction between the dust and the surrounding gas.”
Tough, resilient and able to survive in the most inhospitable regions on Earth –now, they are being asked to show their strength in a space environment as well; blue-green algae (cyanobacteria of the genus Nostoc) and biofilms (deinococcus geothermalis) will depart for the International Space Station (ISS) at 23:44 CEST on 23 July 2014 on board a Progress spacecraft.
Comets have irregular and rather potato-like shapes – this is a well-known fact. But the comet 67P/Churyumov-Gerasimenko, on which the Philae lander is scheduled to descend in November 2014, has an unexpected shape.
The richly varied terrain of Hellespontus Montes on Mars is showcased in these images, acquired by the High Resolution Stereo Camera (HRSC) operated by DLR on board ESA's Mars Express spacecraft. On the western edge of the huge Hellas Planitia impact basin, traces can be seen of the icy streams that once flowed here.
Cassini, the Saturn orbiter, has witnessed countless fascinating phenomena, transmitting exceptional images and measurements back to Earth – including the intricate structure of Saturn's rings, the fountains of ice shot into space from the surface of Enceladus and rivers and oceans of methane on Titan.
Scientists at DLR have used the SOFIA stratospheric observatory to observe a planet outside of the Solar System. Studying its atmosphere will enable them to determine whether this exoplanet is a super-Earth or a mini-Neptune.
A myriad of terrain types are found across the Terra Sirenum region in the southern highlands of Mars. Within the Atlantis basin, a complex and rugged landscape spread across roughly 200 kilometres known as Atlantis Chaos just begins to exemplify the broad diversity of geological processes that occurred in this relatively small area.
The European Space Agency (ESA) Rosetta spacecraft and its lander Philae are currently around two million kilometres from their target comet, 67P/Churyumov-Gerasimenko. Even at this distance, images acquired by the OSIRIS (Optical, Spectroscopic and Infrared Remote Imaging System) camera system already show the comet awakening on its way towards the Sun, enveloped in a cloud of small dust particles. Using these observations, the OSIRIS science team, which includes planetary researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), have been able to determine the comet’s rotation period with additional precision – 12.4 hours. In August, Rosetta will arrive at the comet, and will deploy the Philae lander onto the comet’s surface in November – the first ever landing on a comet.
A vast field of black dunes, towering up to 200 metres in places, is located at the centre of Rabe Crater.
From 20 to 25 May 2014, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will be at the Berlin Air Show (Internationale Luft- und Raumfahrtausstellung; ILA), presenting numerous concepts for more sustainable, safer and comfortable air travel. In the outdoor area at the air show, DLR will be exhibiting a number of its research aircraft, including the Falcon 20E atmospheric research aircraft. The Space Pavilion, designed by DLR in collaboration with its partners, will be showcasing the TORO walking robot and a number of current European space missions.
