Mission managers at NASA's Jet Propulsion Laboratory, Pasadena, California, are assessing an anomaly with the radar instrument on NASA's Soil Moisture Active Passive (SMAP) satellite observatory. The radar is one of two science ...

A new way to view Titan: 'Despeckle' it

During 10 years of discovery, NASA's Cassini spacecraft has pulled back the smoggy veil that obscures the surface of Titan, Saturn's largest moon. Cassini's radar instrument has mapped almost half of the giant moon's surface; ...

Sentinel-1 poised to monitor motion

Although it was only launched a few months ago and is still being commissioned, the new Sentinel-1A radar satellite has already shown that it can be used to generate 3D models of Earth's surface and will be able to closely ...

Typhoon Halong opens its eye again for NASA
