Balloons outfitted with innovative steering devices and robot probes could be the future of planetary exploration. Dr. Alexey Pankine, a fellow at the NASA Institute for Advanced Concepts (NIAC), presented an analysis of balloon applications for planetary science at the World Space Congress in Houston, Texas last month. His study, entitled Directed Aerial Robot Explorers or DARE, is funded by NIAC.
At the center of the DARE concept are balloons that can float in planetary atmospheres for many days. Balloons have long been recognized as low-cost observational platforms and are routinely used in observations of the Earth’s atmosphere. In 1984, two balloons were successfully deployed in the atmosphere of Venus for a short mission. However, what has restrained the wider use of balloons in planetary exploration was the inability to control their paths in strong atmospheric winds. Attaching an engine to a balloon would convert it into an airship and make it too heavy, too power dependent and too expensive to send to another planet or high into the atmosphere.
Faced with this problem, Global Aerospace Corporation has proposed to use an innovative device called the StratoSail® that allows the user to control the path of a planetary balloon. The device is essentially a wing that hangs on a long tether (several kilometers) below the balloon. Strong winds and denser atmosphere at the wing altitude create a sideways lifting force that pulls the entire system across the winds.

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.

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.

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...
