NASA’s NEOWISE has had a busy decade. Since its reactivated mission began on Dec. 13, 2013, the space telescope has discovered a once-in-a-lifetime comet, observed more than 3,000 near-Earth objects, bolstered international planetary defense strategies, and supported another NASA mission’s rendezvous with a distant asteroid. And that’s just a partial list of accomplishments. But all good…

When it comes to influencing climate change, the world’s smallest ocean punches above its weight. It’s been estimated that the cold waters of the Arctic absorb as much as 180 million metric tons of carbon per year – more than three times what New York City emits annually – making it one of Earth’s critical carbon sinks. But recent findings show that thawing permafrost and carbon-rich…

Some 250 students hauled homemade machines they’d spent weeks honing to NASA’s Jet Propulsion Laboratory in Southern California on Friday, Dec. 8, for the 24th annual JPL Invention Challenge. The rules for the creative engineering competition change every year, but the overall goal is the same: Build a device capable of accomplishing a specified task within 60 seconds. This year, teams needed…

For the first time in history, two planets have been home to testing future aircraft designs. On this world, a new rotor that could be used with next-generation Mars helicopters was recently tested at NASA’s Jet Propulsion Laboratory in Southern California, spinning at near-supersonic speeds (0.95 Mach). Meanwhile, the agency’s Ingenuity Mars Helicopter has achieved new altitude and airspeed…
