There’s going to be a spacecraft launched from Vandenberg Air Force Base early Wednesday morning.
An e-mail notice was sent out shortly after 11 p.m. that “launch of Taurus XL/NASA Glory from Vandenberg AFB on schedule for Wednesday Feb 23 at 2:09AM PST. May be visible. No need to call 9-1-1.”
According to the NASA website “the Glory spacecraft and its Taurus XL launch vehicle are coming together at Vandenberg Air Force Base in California as NASA gets ready to launch its first Launch Services Program mission of 2011.
"Glory was designed to study how tiny airborne particles called aerosols affect Earth's climate. The spacecraft, about the size of a refrigerator, is also equipped with an instrument that will measure subtle fluctuations in the amount of energy emit by the sun. Glory is to lift off Feb. 23 at 5:09 a.m. EST.," the NASA website noted.
