• Testing on NASA's Soil Moisture Active Passive (SMAP) observatory is complete, and science operations have begun. The data recorded by the mission, which will give rise to more accurate weather forecasting, will now be subject to a year of validation against existing measurements.
  • NASA mission controllers have successfully deployed the Soil Moisture Active Passive (SMAP) observatory’s reflector antenna, in what is an important step along the road towards the satellite becoming fully operational.
  • On its third attempt, NASA has successfully launched its Soil Moisture Active Passive (SMAP) satellite atop a United Launch Alliance Delta 2 rocket. The orbiter is designed to take high resolution moisture maps on a global scale, mapping the entire planet in the space of only two to three days.
