00:01and vehicle has cleared the tower.
00:06Take normal flight control disturbances for early phase of flight.
00:12All three engines operating nominally.
00:23Vehicle engines operate nominally.
00:25We've just passed 30 seconds into the mission.
00:27The next mark that we're looking for is throttling CORE down.
00:30And we've just started that sequence.
00:33CORE is throttling down as expected.
00:36And we've now reached MPL on CORE right as planned.
00:39Everything looks good.
00:46CORE is at mid-power level.
00:50CORE and starboard strap-on still operating at enhanced power level.
01:00Engine parameters look good.
01:02Flight control surfaces look good.
01:08We have fired the isolation spiral valve on second stage reaction control system.
01:15First step of readying that system for operation.
01:21Pensiones and Regency plans are expected to look good.
01:27And we've passed through Mach 1 and Mach 2.
01:31And we passed through Mach 1 and Mach 2.
01:31And we found that we were working with a new pilot or a new pilot.
01:47CORE and a new pilot.
01:55And we've fired the power valve, pressurizing the reaction control system on the second
01:59stage.
01:59Pressure is coming up.
02:00Everything will be good there.
02:08What we're looking for is going to closed-loop guides.
02:12Coming up in three or four seconds, and we've started closed-loop guide vehicle maneuvering
02:18as expected.
02:19All three engines continue to look good.
02:31And we are three minutes to Corbico.
02:43And the vehicle is now one-half its lift-off weight.
02:46All three engines operating normally.
02:47Everything is looking good.
02:55And the vehicle is now 29 nautical miles in altitude, about 64 miles downrange, traveling
03:02at 5,300 miles per hour.
03:06Everything continues to look good.
03:10And we've just passed through the Karman line, reaching 100 kilometers in altitude.
03:22Everything is looking good.
03:26Two minutes to Corbico coming up on throttle down on the strap-ons.
03:35And we've begun throttling down the strap-on boosters in preparation for cutoff.
03:41We've now achieved mid-power level on the strap-ons.
03:47And cutoff.
03:48We have cutoff port and starboard boosters coming up on strap-on.
03:53And we have strap-on separation.
03:55Disturbances look good.
03:57Brottled up the core booster.
03:59We're now at EPL, the single-stage booster.
04:06And we've re-enabled steering following separation of the strap-ons.
04:10Everything looking good.
04:26One minute, Corbico.
04:32So housing temps respond as expected on the RL10.
04:35And we've started LH2 boost phase chill-down.
04:38Housing temps responding as expected.
04:40Flight control disturbances are small.
04:42And the core RS-68 continues to operate as expected.
04:58About 20 seconds to our next mark event throttling down the core booster in preparation for PICO.
05:18And core booster is settling down, coming up on booster engine cutoff.
05:24And we have PICO.
05:27Cutoff on the booster.
05:28Everything looking good.
05:40And state preparation occurred right as expected.
05:42NEDS have deployed.
05:45And we have pre-start, start, and full thrust.
05:51RL10 is up and running normally.
05:52Everything looking good.
06:08T-minus ten, nine, eight, seven, six, five.
06:15We have ignition.
06:16Two, one.
06:20And liftoff of the final United Launch Alliance Delta IV heavy rocket,
06:25carrying NRL70 for the National Reconnaissance Office,
06:30and closing Delta's six-decade legacy of excellence in space.
07:02VIRUS
07:03Everything is fine, everything looks good.
07:10Or has that been power level?
07:14Or and starboard strap-on still operating at enhanced power level.
07:21You are hearing the voice of Rob Gannon providing launch vehicle ascent data.
07:26The parameters look good.
07:27Like control surfaces look good.
07:32And we have fired the isolation pyrovalve on second stage reactive control system.
07:39And first step in readying that system for operation.
07:46And you look good.
07:51And we've passed through Mach 1 and Mach 2.
07:56Crumple strips there, everything looks good.
08:01All three booths operating as expected.
08:16All three booths operating as expected.
08:19Everything looks good.
08:20And required the pyrovalve pressurized reaction control system on second stage.
08:33All three booths operating as expected.
08:33What we're looking for is going to close booth guides.
08:37We've got three or four seconds.
08:40And we've started close booth guides maneuvering as expected.
08:44And all three engines continue to look good.
