Video: Preparing Delta 2 and SMAP for flight

The weather outlook is 80 percent favorable for launch of the Delta 2 rocket early Thursday morning from California, with cloud thickness posing the only worry, meteorologists report.

A Delta 2 rocket has lifted off from California’s Central Coast on Saturday with a NASA environmental satellite designed to improve flood and drought forecasts, map moisture in Earth’s soils, and track the planet’s water cycle.

The United Launch Alliance Delta 2 was launched Saturday at 6:22 a.m. local time with NASA’s Soil Moisture Active Passive (SMAP) satellite from Vandenberg Air Force Base in California.
