NASA has launched a rocket called Delta 2 (Earth observing mission) from Vandenberg Air Force base in California, for measuring water moisture in soil. The successful launch of Delta 2 will make weather forecasts more accurate with its Earth Observing Satellite. The Soil Moisture Active Passive satellite (SMAP) unit on board will measure moisture levels in top 2 inches (5 cm) of soil on Earth.  This will help to track weather systems, predict droughts and floods, and the changing climate for three years. SMAP is one of five Earth-monitoring satellites originally scheduled for launch in 2014.

Knowledge is Wealth

  • The Remote Sensing satellites are helpful in many areas such as agriculture, water resources, urban planning, rural development, mineral prospecting, environment, forestry, ocean resources and disaster management.
  • NASA’s was established in 1958 and its Headquarters is in Washington.
  • NASA’s Motto – For the Benefit of all.
  • ISRO’s Motto – Space Technology in the Service of Human Kind
