Rocket blasts off with NASA satellite to track climate change

A NASA satellite lifted off early Saturday with the hope it will transmit data that will help the world do a better job of preparing for floods and droughts. The satellite is on a three-year mission to track the amount of water locked in soil, which may help residents in low-lying regions brace for floods or farmers get ready for drought conditions. The Delta 2 rocket carrying the Soil Moisture Active Passive — or SMAP — satellite launched shortly before sunrise from Vandenberg Air Force Base on California’s central coast. Once the satellite reaches the desired orbit 430 miles high, engineers will spend two weeks checking out the two instruments, which will measure moisture in the soil every several days to produce high-resolution global maps.

This data will benefit not only scientists seeking a better understanding of our planet, climate and environment … it’s a boon for emergency planners and policy makers.

Scientists hope data collected by the satellite, the latest to join NASA’s Earth-orbiting fleet, will improve flood forecasts and drought monitoring. Currently, drought maps and flash flood guidance issued by the federal government are based on computer modeling. SMAP will take real-time measurements that can be incorporated into forecasts, said Dara Entekhabi, mission science team leader from the Massachusetts Institute of Technology. The rocket was supposed to fly earlier this week, but high winds and technical problems kept it grounded.
