Ryugu and other asteroids of the common ‘C-class’ consist of more porous material than was previously thought. Small fragments of their material are therefore too fragile to survive entry into the atmosphere in the event of a collision with Earth. This has revealed the long-suspected cause of the deficit of this meteorite type in finds on Earth.
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and five European companies have teamed up in the RETro Propulsion Assisted Landing Technologies (RETALT) project to jointly advance the research and development of key technologies for European vertical-landing launch vehicles.
There is a new plan to support the German Aerospace Center (DLR) Mars ‘Mole’ that is part of NASA’s InSight mission. The Heat Flow and Physical Properties Package (HP3) Mole is a self-driving penetrator that has hammered itself into the Martian subsurface to a depth of approximately 30 centimetres.
Low-cost flights from Germany set a new record in the winter half-year 2018/2019. For the first time, there were 5325 low-cost airline flights per week, which represents a 10 percent increase from the previous year. The market has now almost settled down following the withdrawal of Air Berlin.
A blue box, a cubic metre of Mars-like sand, a rock, a fully-functional model of the Mars 'Mole' and a seismometer – these are the main components with which the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) is simulating the current situation on Mars.
The compact German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Eu:CROPIS satellite is now rotating in space at a rate of 17.5 revolutions per minute, generating a gravitational force in its interior similar to that found on the Moon. After its launch on 3 December 2018, DLR engineers successfully tested and commanded the spacecraft.
Whether it is the digital management of energy supply, thermal storage power plants as a clean route away from coal, autonomous flying multicopters that monitor the solar fields, or high-tech analysis technology for batteries of the next generation and beyond – the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will be present at the Hannover Messe to showcase future-oriented technologies and concepts for the implementation of the Energy Transition, as well as products and services that have successfully made their way from research into practical applications in industry thanks to DLR Technology Marketing.
Earth is a very special planet. It is the only celestial body in the Solar System on which we know life exists. Could there be life on other planets or moons? Mars is always the first to be mentioned in this context; it has many properties in common with Earth, and in its geological past water also flowed over its surface.
The German Aerospace Center (DLR) will command the Mars ‘Mole’ to begin a short new round of hammering at the end of March. The seismometer and the camera will closely monitor the movement of the Mole. The researchers want to analyse in more detail the situation of the self-hammering probe, which has shown no further progress since it reached a depth of approximately 30 centimetres at the beginning of March. Different ideas for releasing the Mole require a more detailed analysis of the situation and at least a few more weeks to test different strategies on Earth.
A special experiment will begin at the Institute of Biomedical Problems of the Russian Academy of Sciences (IBMP RAS) in Moscow on 19 March 2019 at 14:00 local time. Just four months before the celebrations for the fiftieth anniversary of the first Moon landing by the Apollo 11 astronauts, three female and three male 'cosmonauts' will embark on a simulated journey to our terrestrial neighbour.
