Mission: THEMIS (Time History of Events and Macroscale Interactions During Substorms)
Launch Pad: 17-B, Cape Canaveral Air Force Station
Launch Vehicle: Delta II (United Launch Alliance)
Launch Date: Feb. 16, 2007

The launch of THEMIS aboard a Delta II rocket scheduled for Thursday, Feb. 15, has been postponed 24 hours. Loading of hypergolic propellants aboard the second stage of the vehicle was unable to be completed today. Thunderstorms and severe weather moved into the Cape Canaveral vicinity ahead of an advancing cold front that prevented fueling from continuing. The launch window on Friday, Feb. 16, extends from 6:05 to 6:23 p.m. EST.
The THEMIS prelaunch press conference and mission science briefing has also been rescheduled one day to Thursday and will start at 3 p.m. EST. All other events for the news media will be at their same times one day later. Coverage of the launch on NASA Television will begin at 3:45 p.m. EST on Friday.
