Today, he is a hostile desert planet – but in the meantime is considered to be secured: a long time Ago the surface of Mars was shaped by liquid water. Thus could also have developed in organisms. Traces of these former creatures hide in the red surface, or there may still be microbes? These and other questions will soon follow new probes more accurately than ever before. The ambitious project is set to start in the summer of this year and will also serve the preparation of future manned missions to the red planet.
In the first article of the four-part title theme of the bdw-author Thorsten Dambeck reports on this exciting major project. In the center is a particularly complex Mission: "Mars Sample Return is". The space agencies NASA and ESA plan, soil samples from Mars to earth. Three space probes to win in a former river Delta on Mars. Experts call the project "Apollo without astronauts" – because, unlike in the case of the flights to the moon this time will automatically work to the end of the tricky probes endeavor do – from sampling to the shipment of the "Post" to the earth. How to make that work, the author describes.answers and many questions
In the article "methane, meteorites, and dust devil" is Dambeck then current knowledge and questions about the features of our neighbouring planet in focus. As he reported, are now the causes of the drying up of the red desert world. Massive dust storms apparently plays a role and, above all, losses to the All: the water molecules to rise into the upper atmosphere and disappear forever. In addition, the author of the question is: Could be the methane in the atmosphere of Mars microbes?
the title theme of a look at "tracks and speculation is of life Rounded off" to the theme on the Mars. The bdw-editor Rüdiger Vaas reported about strange structures on photos of the previous NASA Rover missions, which give rise to speculation about extraterrestrial life. On the planet could once have been microbes, algae, and fungi exists – perhaps even up to today, the author writes in the article "algae and fungi on Mars?"
