Weeks before U.S. pilots took to the skies above Afghanistan last October, they had a pretty good idea what they would see there. Already they had logged many hours doing virtual fly-throughs over the rugged mountain terrain, using a mission rehearsal system known as Topscene (for tactical operational scene). Built for the U.S. Department of Defense by Anteon Corp., Fairfax, Va., Topscene combines aerial photos, satellite images, and intelligence data to create high-resolution three-dimensional databases of a region.

Seated at computer consoles running on Silicon Graphics Onyx processors, pilots could visualize flying from ground level up to 12 000 meters, at speeds up to 2250 km/h. The detailed renderings, showing roads, buildings, and even vehicles, helped them plot the best approach, scout for landmarks, and identify designated targets.

Engineers Are Working on a Solar Microgrid To Outlast Lunar Nights

Future lunar bases will need power for mining and astronaut survival

The next time humans land on the moon on the moon, they intend to stay awhile. For the Artemis program program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a base at which astronauts can live and work.

One of the crucial elements for a functioning lunar base is a power supply. Sandia National Laboratories, a research and development lab that specializes in building microgrids for military bases, is teaming up with NASA to design one that will work on the moon.

Trilobite-Inspired Camera Boasts Huge Depth of Field

New camera relies on "metalenses" that could be fabricated using a standard CMOS foundry

Inspired by the eyes of extinct trilobites, researchers have created a miniature camera with a record-setting depth of field—the distance over which a camera can produce sharp images in single photo. Their new study reveals that with the aid of artificial intelligence, their device can simultaneously image objects as near as 3 centimeters and as far away as 1.7 kilometers.

Five hundred million years ago, the oceans teemed with horseshoe-crab-like trilobites. Among the most successful of all early animals, these armored invertebrates lived on Earth for roughly 270 million years before going extinct.

Reduce EMI and EMC Issues with Engineering Simulation Software

Electronic components and systems exist today in nearly all consumer and industrial products. A major design consideration in all electronics is electromagnetic interference (EMI) and compatibility (EMC). EMI and EMC issues are complex. They can be hard to detect and can be taxing to a design. With the use of engineering simulation software, design engineers can mitigate issues before entering the prototype testing phase. Avoiding the test-retest cycle with simulation can help save time and money all while delivering robust and reliable products.
