The Soil Moisture Active Passive (SMAP) satellite, as the name implies, contains an active radar sensor and a passive radiometer. This was successfully launched on 29 January 2015 but the radar sensor failed in July of this year. A collection of NASA and other scientists have been looking for alternative sources of radar data to match with the radiometer data from SMAP. You can read more about this effort in the Space News article at: http://spacenews.com/scientists-hopeful-of-salvaging-smap-following-loss…
Even without the radar sensor, the radiometer continues to produce very useful data. One recent example is the extraordinary flooding event in South Carolina in early October.
