NASA's CATS concludes successful mission on Space Station
Greenbelt MD (SPX) Dec 12, 2017
A spaceborne lidar instrument that fired more laser pulses than any previous orbiting instrument has ended its operations on the International Space Station, after a successful 33-month mission to measure clouds and tiny atmospheric particles that play key roles in Earth's climate and weather. During its mission, NASA's Cloud-Aerosol Transport System (CATS) lidar provided measurements of the vertical structure of clouds and aerosols, including volcanic eruptions, man-made pollution in China and In ... read more
