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.

“We had a terrific ride into space aboard the United Launch Alliance’s Delta 2 vehicle. They deposited us exactly where we wanted to be with with accuracy and precision,” said Kent Kellogg, NASA’s SMAP project manager.

The United Launch Alliance Delta 2 rocket lifts off with NASA’s SMAP observatory at 6:22 a.m. local time on Saturday, Jan. 31 from Vandenberg Air Force Base in California.
