Delta IV GPS IIF SV-1 Mission Tentatively Rescheduled for May 27

 

Cape Canaveral AFS, Fla. (May 24, 2010) - The launch attempt of the United Launch Alliance Delta IV with the Air Force's Global Positioning System IIF SV-1 satellite (GPS IIF SV-1) was scrubbed tonight. During the final seconds of the launch countdown, an anomalous data signature with the thrust vector control system on one of the two solid rocket motors mounted to the Delta IV booster was detected. The thrust vector control system is used to steer the SRMs during flight.  The data signature triggered an automatic abort in the launch countdown scrubbing tonight's launch attempt. Mission managers are currently studying the situation to determine a corrective action plan.

 The Delta IV rocket and GPS IIF SV-1 satellite are safe and secure at this time. The next launch attempt has been tentatively set for Thursday. When a decision is made determining the next launch attempt it will be announced.  The launch window for Thursday is 11:00 -11:19 p.m. EDT.

0405 GMT (12:05 a.m. EDT)
The Delta 4 rocket was just moments away from roaring to life and launching from Cape Canaveral's pad 37B on Monday, but a dramatic last-second abort stopped the countdown.

It was the third attempt to launch the mission carrying the first in a new generation of satellites for the Global Positioning System, and clocks were heading toward liftoff at 11:13 p.m. EDT after a smooth countdown throughout the evening.

"T-minus 15 seconds," the timer said.

"Ignitors armed," a launch team member called.

"ROFI ignition," said another engineer, referring to the radial outward firing ignitors that burn hydrogen beneath the main engine.

"T-minus 10, 9, 8, 7," the timer continued.

"Hold, hold, hold," a voice sounded.

The countdown sequencer script had aborted, automatically stopping the Delta 4 rocket from lighting its main engine and solid rocket boosters.

Well-rehearsed safing procedures began immediately to put the launch vehicle, the Complex 37 facility and GPS spacecraft into a secure configuration.

The Terminal Countdown Sequencer Rack, or TCSR, takes control at T-minus 8.5 seconds and guides activities through liftoff. Ignition of the RS-68 powerplant follows at T-minus 5.5 seconds. The engine begins to produce thrust at T-minus 3.3 seconds and then powers up to the 102 percent throttle at T-minus 1 second for a computer-controlled checkout before liftoff. The solid rocket boosters are lit at T-minus 20 milliseconds.

But Monday's attempt never actually got down to ignition. Computers detected a possible problem with the steering system on one of the twin solid rocket boosters.

The strap-on motors, which burn for 94 seconds to give the Delta a powerful kick toward space, use hydraulics to swivel their nozzles and steer the rocket.

A joint statement to the press from the Air Force and United Launch Alliance said "an anomalous data signature" from the steering system triggered the countdown's abort.

"Mission managers are currently studying the situation to determine a corrective action plan," the statement says.

The earliest that launch could be rescheduled is Thursday night. That day's window would extend from 11:00 to 11:19 p.m. EDT.
0337 GMT (11:37 p.m. EDT Mon.)
A video clip of tonight's countdown abort is posted here.
0324 GMT (11:24 p.m. EDT Mon.)
Draining of the propellants from the Delta rocket has begun.
0322 GMT (11:22 p.m. EDT Mon.)
The way the Delta 4 rocket's countdown works, the terminal sequencer takes control at T-minus 8.5 seconds. Ignition of the RS-68 powerplant follows at T-minus 5.5 seconds. The engine begins to produce thrust at T-minus 3.3 seconds and then powers up to the 102 percent throttle at T-minus 1 second for a computer-controlled checkout before liftoff. The solid rocket boosters are lit at T-minus 20 milliseconds.

The announcer had called T-minus 7 seconds right when another team member called the hold tonight.
0320 GMT (11:20 p.m. EDT Mon.)
Since the hydrogen burnoff sparklers had fired, that was the only shot at launching tonight. The solid rocket boosters' hydraulic systems will have to be reset during the scrub turnaround as well.

Exactly when the next launch attempt will be made is not known as this time.

This was the last date available on the Eastern Range for the launch to occur before to Wednesday morning's scheduled landing of the space shuttle Atlantis. The Range requires time in between events to reconfigure its tracking and communications equipment. So the next try, based purely on the Range, wouldn't be possible until late in the week.

0317 GMT (11:17 p.m. EDT Mon.)
The Delta 4 rocket and the GPS 2F-1 spacecraft have completed their switch back to external power.

0315 GMT (11:15 p.m. EDT Mon.)
Safing of the launch vehicle and pad systems is underway. There's no immediate word on what caused the hold.

0314 GMT (11:14 p.m. EDT Mon.)
An abort occurred inside the final seconds of the countdown when the sequencer was taking control of events leading up to liftoff. The hold was triggered just prior to main engine start.

0312 GMT (11:12 p.m. EDT Mon.)
HOLD! Countdown has been halted just before ignition!

0312 GMT (11:12 p.m. EDT Mon.)
T-minus 12 seconds. Residual hydrogen burnoff ignitors have been fired beneath the main engine.

Не знал... А почему на Дельте-2 обходились неуправляемыми, а тут поставили управляемые? Тяга же основного двигателя в 3 раза больше, должно хватать? Тем более тут всего 2 ускорителя...

1535 GMT (11:35 a.m. EDT)
Now that the space shuttle Atlantis mission has successfully concluded, full attention turns to Cape Canaveral's Complex 37 launch pad where a Delta 4 rocket will try again tonight to get into orbit and deploy an advanced Global Positioning System satellite. Liftoff time is 11:00 p.m. EDT (0300 GMT).

The United Launch Alliance ground team just rolled back the 33-story mobile service to reveal the Delta for today's countdown. The structure had been put back around the rocket after Monday night's scrub.

The wheeled gantry moves along rail tracks to its launch position about the length of a football field from the rocket. The 9-million pound tower shields the Delta from the elements during the its stay on the pad, provides workers 360-degree access to the various areas on the vehicle and is used to attach the strap-on solid motors and the payload during the launch campaign. The tower is 90-feet wide and 40-feet deep.

Crews will spend the next couple of hours securing the complex for launch before leaving the danger area around the pad. All workers must be clear of the area for the start of hazardous operations in the countdown, which include fueling the vehicle later this afternoon.

The Terminal Countdown will begin ticking at 4:30 p.m. EDT, leading to the multi-hour process of loading the Delta 4's Common Booster Core first stage and the upper stage with supercold liquid oxygen and liquid hydrogen propellants.

Tonight's launch opportunity extends 19 minutes from 11:00 to 11:19 p.m. EDT.

The officials have not announced how the solid rocket booster steering issue that caused Monday's countdown abort was resolved. But preparations are underway for this next launch attempt.

1514 GMT (11:14 a.m. EDT)
Tower rollback has begun for tonight's launch of the Delta 4 rocket.

0456 GMT (12:56 a.m. EDT)
T+plus 1 hour, 56 minutes. The upper stage has completed one passive roll program and just started another. This one will continue until it's almost time for the next burn.

0430 GMT (12:30 a.m. EDT)
T+plus 90 minutes. Unlike the previous generations that rode on smaller rocket Delta 2 rockets, the dozen next-generation GPS 2F craft will be delivered into orbit atop the Delta 4 and Atlas 5 fleets of boosters in the Air Force's Evolved Expendable Launch Vehicle program.

The Delta 2's, although highly reliable, weren't powerful enough to inject the GPS satellites directly into the orbiting constellation. The three-stage vehicles released the craft into a highly elliptical orbit stretching from 100 miles at its closest point with Earth to some 11,000 miles at its highest point, which is the altitude where the GPS network resides. The newly-launched satellites were themselves fitted with a solid-fuel kick motor that ignited a few days into flight and finished the job of propelling the craft into a circular orbit.

United Launch Alliance's powerful Delta 4 and Atlas 5 rockets will haul the GPS 2F satellites directly to their desired destinations, bypassing the circuitous route of the past. So instead of taking days to reach the GPS orbit, the new 2F-1 satellite will get there in three-and-a-half hours tonight.

0415 GMT (12:15 a.m. EDT)
T+plus 75 minutes. To recap, the Delta 4 rocket carrying the GPS 2F-1 navigation satellite launched from Cape Canaveral's Complex 37 at 11:00 p.m. EDT.
