Irish weather warning ahead of Storm Austen

From orbit, today’s space-based laser instruments measure Earth’s forests and terrain one narrow line at a time. Between those lines are enormous gaps that include millions of acres of land scientists never directly measure. NASA’s CASALS instrument will blend machine learning with an ultra-compact lidar instrument to adaptively ‘sweep’ large swaths of Earth’s surface. This […]

A £3.6bn proposal to stop sewage being discharged into Windermere, England's largest lake, has been unveiled. The plans, which are backed by the local water company United Utilities and clean water campaigners, would see a tunnel up to 12 miles (19km) long built to transport sewage away from the lake.

Destined for Mars and beyond, NASA’s Space Reactor-1 (SR-1) Freedom will be humanity’s first fission-powered spacecraft to travel outside Earth’s orbit. Announced during NASA’s “Ignition” event, this mission will demonstrate nuclear electric propulsion in deep space, and progress is underway on its key element: the nuclear power module. To expedite development of the spacecraft, NASA […]
