Japan launches satellite for advanced GPS operation
Japan on Saturday launched an H-2A rocket carrying a geo-positioning satellite into orbit after a week-long delay, the government said. The launch of Japan's third geo-positioning satellite is part of its plan to build a version of the U.S. global positioning system (GPS) to offer location information used for autopiloting and possible national security purposes.
Solar eclipse presents first major test of power grid in renewable era
As Monday's total solar eclipse sweeps from Oregon to South Carolina, U.S. electric power and grid operators will be glued to their monitoring systems in what for them represents the biggest test of the renewable energy era. Utilities and grid operators have been planning for the event for years, calculating the timing and drop in output from solar, running simulations of the potential impact on demand, and lining up standby power sources. It promises a critical test of their ability to manage a sizeable swing in renewable power.
Millions of Americans to gaze upon Monday's once-in-a-lifetime eclipse
Twilight will fall at midday on Monday, stars will glimmer and birds will roost in an eerie stillness as millions of Americans and visitors witness the first total solar eclipse to traverse the United States from coast to coast in 99 years. The sight of the moon's shadow passing directly in front of the sun, blotting out all but the halo-like solar corona, may draw the largest live audience for a celestial event in human history. When those watching via broadcast and online media are factored into the mix, the spectacle will likely smash records.
