0340 GMT (11:40 p.m. EDT Thurs.)
T+plus 40 minutes. The rocket has started the planned
thermal-controlling roll program. It will continue in this roll for
about 75 minutes.
0327 GMT (11:27 p.m. EDT Thurs.)
T+plus 27 minutes, 30 seconds. The rocket is 214 miles in altitude,
5,460 miles downrange.
0327 GMT (11:27 p.m. EDT Thurs.)
T+plus 27 minutes. The rocket has just entered a two-hour, 56-minute
coast period before the final engine burn to deliver GPS 2F-1 into the
desired orbit this evening.
0326 GMT (11:26 p.m. EDT Thurs.)
T+plus 26 minutes, 5 seconds. Delta is 166 miles in altitude, 5,070
miles downrange from the launch pad and traveling 32,042 feet per second.
0324 GMT (11:24 p.m. EDT Thurs.)
T+plus 24 minutes, 40 seconds. SECO 2. The second of three firings by
the upper stage during tonight's launch has been completed.
0324 GMT (11:24 p.m. EDT Thurs.)
T+plus 24 minutes. This burn injects the rocket into a highly elliptical
orbit stretching about 11,000 nautical miles at its furthest point.
0323 GMT (11:23 p.m. EDT Thurs.)
T+plus 23 minutes, 30 seconds. About one minute left in this burn by the
Delta 4 rocket's upper stage.
0323 GMT (11:23 p.m. EDT Thurs.)
T+plus 23 minutes, 15 seconds. The initial orbit achieved hit the
expected targets.
0322 GMT (11:22 p.m. EDT Thurs.)
T+plus 22 minutes, 40 seconds. Good engine chamber pressure reported.
0322 GMT (11:22 p.m. EDT Thurs.)
T+plus 22 minutes. This burn will last just over three minutes in duration.
0321 GMT (11:21 p.m. EDT Thurs.)
T+plus 21 minutes, 23 seconds. Ignition! The RL10B-2 engine, fed by
liquid hydrogen liquid oxygen, has been reignited to propel GPS 2F-1
into an intermediate orbit.
0317 GMT (11:17 p.m. EDT Thurs.)
T+plus 17 minutes. The vehicle is now in a coast mode before the next
firing of the upper stage engine. Ignition of the RL10 engine is now
four minutes away.
0313 GMT (11:13 p.m. EDT Thurs.)
T+plus 13 minutes. Delta is 167 miles in altitude, 1,891 miles downrange
from the launch pad.
0312 GMT (11:12 p.m. EDT Thurs.)
T+plus 12 minutes, 14 seconds. SECO 1. The upper stage engine has shut
down after the first of three planned firings to inject the GPS
spacecraft into navigation network tonight.
0311 GMT (11:11 p.m. EDT Thurs.)
T+plus 11 minutes, 27 seconds. Delta is 172 miles in altitude, 1,544
miles downrange from the launch pad.
0310 GMT (11:10 p.m. EDT Thurs.)
T+plus 10 minutes, 50 seconds. The upper stage's the RL10 engine working
well, still firing as planned to reach a low-altitude parking orbit this
evening.
0310 GMT (11:10 p.m. EDT Thurs.)
T+plus 10 minutes, 5 seconds. The vehicle's steep climb leveled off as
it gains speed toward orbital velocity.
0309 GMT (11:09 p.m. EDT Thurs.)
T+plus 9 minutes, 50 seconds. Delta is 169 miles in altitude, 1,216
miles downrange from the launch pad.
0309 GMT (11:09 p.m. EDT Thurs.)
T+plus 9 minutes, 20 seconds. About three minutes remain in this firing
of the upper stage to place the vehicle into an initial parking orbit
around Earth.
