From the Associated Press:
The GOES-N satellite took off about 6 p.m. on a Boeing Delta 4 rocket from the Cape Canaveral Air Force Station. The satellite separated from the rocket as scheduled about 10:30 p.m., putting it on a path for orbit.
The last time a Delta 4 rocket flew — a test flight of the rocket's heavy-lift model in December 2004 — it failed to put a dummy satellite into its intended orbit.
A launch scheduled last August was scrubbed after an alarm indicated low voltage on batteries powering the system that allows the rocket to transmit data to ground stations. The delay was the latest in a series of setbacks dating to last May.
The GOES-N is a step in the development of a family of weather satellites designed and built by NASA and the National Oceanic and Atmospheric Administration since 1975. It is the first in a series of three new satellites.
