Assuming nothing went awry when NASA's Phoenix mission descended onto Mars in May, a meteorological station provided by the Canadian Space Agency is now acquiring, processing and transmitting temperature and pressure data back on Earth. Recording the daily weather of the martian northern plains lets scientists understand the martian climate and geology, which will help them answer the age-old question: Did life ever exist?
Sunlight in the martian polar region is even weaker than at its equator, so the battery- and solar-powered systems must feature extremely efficient power management. Radiation-tolerant RTAX-S FPGAs from Actel Corp. are among the components that let this one-of-a-kind instrument meet these requirements.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
