ESAs Mars Express is due to arrive at Mars in December 2003, and its Beagle 2 lander will be making a touchdown in the middle of the Martian winter. Will it see a white Christmas on the Red Planet? Also, if humans one day go to Mars, would they need to take a sunscreen?
Over its four-year lifetime, Mars Express will be returning data to refine the latest computer models of the Martian climate. It will be closely watching the clouds, fog, dust devils, and storms, looking for clues to explain the climate changes on Mars, now and in the past, and to better prepare us for future missions.
ESA scientists are already working to make sure that future missions to Mars arrive safely, and that future human explorers know what kind of weather to expect. They have developed a global atmospheric circulation model for Mars, which uses the same principles as those used to predict weather on Earth. Weather data sent back from Mars Express will help us to perfect these Martian weather forecasts.
This winter, the weather will be similar to that of the Earth, but colder. Mars Express will experience cold, cloudy mornings and cool, hazy afternoons. Some of the clouds could be made of water-ice crystals, but most clouds are made of crystals of carbon dioxide, or dry ice. Temperatures will fall below –125°C but, because there is not enough moisture in the atmosphere to produce a significant amount of snow, Beagle 2 itself will not see a white Christmas.

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
