What effects do tropical clouds have on our climate? Do they warm up or cool down the atmosphere? What factors do they influence? Even the latest models do not fully understand the effects of these climate-influencing 'clouds'.
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.”
These images, acquired by the High Resolution Stereo Camera (HRSC), on board the European Mars Express spacecraft, operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), show part of the Meridiani Planum region.
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?
Falcon took to the skies for the first time 40 years ago today. It left the French aircraft manufacturer Dassault and headed to DLR Flight Operations in Oberpfaffenhofen.
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.
With a length of 600 kilometres and a depth of up to two kilometres, Mawrth Vallis is one of the biggest valleys on Mars and a possible landing site for the ESA ExoMars and NASA Mars 2020 missions. It is entrenched in the Arabia Terra highland, which is more than four billion years old, and ends in the great Chryse Planitia lowland region.
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.
