Keck Telescopes Get a Motion Control Upgrade

In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea mountain summit has no nearby ranges to roil the upper...

Ordinary WiFi can easily detect weapons, bombs, and explosive chemicals in bags at museums, stadiums, theme parks, schools, and other public venues using a low-cost suspicious...

GPS signals do not penetrate very deeply or at all in water, soil, or building walls, and therefore can’t be used by submarines or in underground activities such as surveying mines. GPS also...

Along with intensity and color, polarization is a property of light that can provide useful information for scene analysis; however, the human eye and most cameras cannot detect...

Innovators at NASA’s Glenn Research Center have developed a hybrid telescope antenna system — Teletenna — to deliver high-data-rate communication over great distances. Teletenna has...
