Opis:
Picture MUST credit: NASA/JPL-Caltech A satellite packed with a giant radar antenna, folded like an umbrella has just unfurled in orbit for a first of its kind mission. The satellite was launched to monitor Earth's surfaces detecting movement of the planet's crust down to centimetres. The massive, drum-shaped structure is on a mission called NISAR, a joint effort between US space agency NASA and India space agency ISRO. It launched on July 30 from Satish Dhawan Space Centre in India. More than two weeks later, the satellite deployed its antenna reflector, which spans 12 meters—the largest ever used on a NASA mission. NISAR is designed to produce a three-dimensional view of Earth in unprecedented detail. It will enable researchers and data users to create 3D movies of changes happening on Earth's surface. It will track the motion of ice sheets and glaciers, the deformation of land due to earthquakes, volcanoes, and landslides, and changes in forest and wetland ecosystems. It also will aid decision-makers in fields as diverse as disaster response, infrastructure monitoring, and agriculture. Picture supplied by JLPPA
