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. Â 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.
