The comet lander Philae has been found. The OSIRIS camera on board the Rosetta orbiter took the revealing images of the surface of Comet 67P/Churyumov-Gerasimenko on 2 September 2016. They show the landing craft lying sideways in a crevasse. Two of the three landing legs are clearly visible.
The National Aeronautics and Space Administration (NASA) has finally confirmed the new launch date for the InSight mission, with the first launch opportunity to the Red Planet set for 5 May 2018. The mission was in fact scheduled for launch in March 2016, and land on Mars six months later.
In the Situation Centre, an alarm flashes on the screen – a passenger ferry has changed its planned course for no apparent reason. The AIS (Automatic Identification System) signal eventually disappears from the display. By now, all ship-specific information must have been requested and compared in order to quickly clarify the situation and take immediate action.
West Africa is changing. An explosively growing population, massive urbanisation, complex meteorological influences, unregulated deforestation and air pollution modify the composition of the atmosphere, not only impacting human health but also the weather and climate. How bad the problem actually is and how exactly these emissions are changing the region in the long-term is not yet clear. Researchers from the German Aerospace Center (DLR) used the Falcon research aircraft to analyse the tropical air on the West African coast in order to determine its composition and its effect on the clouds’ climate-relevant properties. The measurement flights were part of the five-year EU project DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa)..
Headaches, nausea or even swollen hands and feet: the test subjects currently ascending at a rapid pace to Europe’s highest building to voluntarily experience altitude sickness have all of these things coming their way. Ten test subjects will gather at the Margherita Hut in the Valais Alps in Italy, where their bodies will be closely monitored to see how they respond to an altitude of 4554 metres above sea level, oxygen depletion and low air pressure. “If astronauts are stationed in a Mars habitat some time in the future, it is extremely probable that they will live and work in an atmosphere with similar pressure conditions,” explains Ulrich Limper, the mission’s medical director from the German Aerospace Center (DLR). “As things stand, though, we are unable to predict which persons will experience altitude sickness and what the causes may be.” A possible explanation: “The oxygen depletion encountered at high altitudes damages the vascular barrier, allowing fluid and proteins to seep into the connective tissue. In some instances, this will produce dangerous oedema in the body, especially in the lungs and the brain.”
Rail accidents, even those that occur at low speeds, can have devastating consequences – in many cases, hundreds of tons of moving mass collide with each other, and carriages crash into each other or even derail.
It's hard to say what surprised scientists and engineers the most during the Rosetta mission: the unusual form of Comet 67P/Churyumov-Gerasimenko that earned it the nickname 'Rubber Duck'? The bizarre, unexpectedly varied landscape with fissures, terraces, crevasses, steep cliffs and even dune-like structures?
Ships can be led astray with fake GPS signals. If signals for navigation of vessels are jammed or spoofed, positional and other critical data, such as course and speed, can be affected. Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have tested new receiver systems and methods for suppressing interference in a three-day measurement campaign.
A new corporate network will ensure increased safety and lower costs in the field of maritime traffic in future. Five private companies and a research institute are now working together within the MARSAT project to develop new services for the maritime industry using satellite data.
The exterior of a rocket is exposed to extremely high temperatures during hypersonic flight. But how exactly does the surface structure change under varying air resistance and with respect to heat flow and acceleration?
Today, the analysis and use of satellite images is commonplace. Just 15 years ago, however, only a handful of specialists worked with these valuable data. Since then, a particular niche expertise has rapidly developed – the use of satellite data for disaster management.
Space travel is no easy task – first comes the stressful launch with vibrations, then the long flight through the bitter cold and the vacuum. The Mobile Asteroid Surface Scout (MASCOT) has been travelling on board the Japanese Hayabusa2 spacecraft for the last one-and-a-half years, and is currently at approximately 65 million kilometres from Earth.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has been actively involved in humanitarian aid for many years. Alongside government partners, the private sector and scientific institutions, DLR is supporting the United Nations World Food Programme (WFP) work towards a world with zero hunger.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with the Zittau/Görlitz University of Applied Sciences and Dresden University of Technology, has developed a method that accurately simulates the flow of steam in turbomachines up to 10 times faster than has previously been possible.
The small containers that are currently being disassembled at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are rather inconspicuous, yet they may contain organisms that have endured the conditions of space for over 530 days.
For the first time, the number of worldwide flights in June exceeded the three million planned take-offs mark – an increase of 3.5 percent compared to the previous year. This is one of the findings in the latest Global Aviation Monitor.
Earth observation satellites fly at distances of up to several hundred kilometres from Earth and can provide detailed information that assists relief workers on the ground.
On 22 June 2016 at 05:55 CEST, the BIROS (Bi-Spectral Infrared Optical System) microsatellite was successfully launched into space from the Satish Dhawan Space Centre in India on board a Polar Satellite Launch Vehicle (PSLV).
The surgeon sits at a console, while robotic arms perform his commands with high precision on the patient – making exact incisions, putting in screws or stitching severed veins in a tiny space. During the operation, the doctor can feel through the controls exactly what the instrument tips on the robot are doing, just as if he were holding them in his own hands.
Out of 550 astronauts that have flown in space, only 60 have been women. The four female European spacefarers in this small group came from Britain, France and Italy. Germany has not yet had a female astronaut. In the late 1980s, German candidate astronauts Heike Walpot and Renate Bruemmer trained to go into space, but neither eventually flew on a space mission.
