The Delta II rocket is fully fueled for launch following the completion of LOX loading activities.
The hexagon-shaped OCO-2 spacecraft was built by Orbital Sciences Corp. and weighs in at almost 1,000 pounds. Two 10-foot-long solar arrays will power all the observatory's systems — including its only scientific payload. This instrument comprises three spectrometers that will break the sunlight reflected up from Earth's surface into its component colors, then focus on …
The OCO-2 spacecraft will be delivered to orbit by a Delta II rocket – an industry workhorse with decades of success for NASA missions. The two-stage vehicle stands 128 feet tall and measures eight feet in diameter, with a 10-foot payload fairing. At T-0, the first-stage engine ignites along with the rocket's three solid-rocket boosters. …
Liquid oxygen loading is in progress.
The next major countdown milestone is the loading of liquid oxygen, or LOX, into the rocket's first stage. LOX is chilled to a very cold minus-297 degrees, making it a cryogenic propellant. NASA Launch Manager Tim Dunn polled his team and received the "go" to start this process a few minutes from now. ULA Launch Conductor …
Weather and wind conditions at Vandenberg will not pose a problem for the launch team this morning. The marine layer that brings fog to the coast is creeping into the area, but skies are clear above. Visibility at launch time is predicted to be 1 to 2 statute miles and winds will be light at …
