1037 GMT (6:37 a.m. EDT)
NEW LAUNCH TIME. Liftoff is being retargeted for 8:39 a.m. EDT.

The countdown clocks are going to be reset for the new time.
1030 GMT (6:30 a.m. EDT)
The launch team has been instructed not to start liquid oxygen loading as this next band of showers moves through.
1028 GMT (6:28 a.m. EDT)
NASA launch manager Omar Baez has completed a poll to confirm the agency management team is "go" for liquid oxygen loading.
1021 GMT (6:21 a.m. EDT)
Weather forecasters hope the showers will clear out by about 7 a.m. EDT. Lingering clouds will remain the concern.
1017 GMT (6:17 a.m. EDT)
There's some light rain just east of the launch site moving onto the coast. The current weather conditions are violating cumulus and anvil cloud rules, the electrical potential in the air and rain in the rocket's flight path.
1014 GMT (6:14 a.m. EDT)
The launch team has completed work to turn on and configure the Delta's onboard guidance computer.
1007 GMT (6:07 a.m. EDT)
The next milestone in the count will be loading super-cold cryogenic liquid oxygen into the first stage starting about 30 minutes from now.

The kerosene and liquid oxygen will be consumed by the stage's Pratt & Whitney Rocketdyne RS-27A main engine and twin vernier steering thrusters during the initial four-and-a-half minutes of flight.
1005 GMT (6:05 a.m. EDT)
The first stage fuel tank of the Delta 2 rocket has been fully loaded for today's planned 8:00 a.m. EDT launch. The tank was filled with a highly refined kerosene, called RP-1, during a 19-minute, 25-second process that concluded at 6:05 a.m.
1002 GMT (6:02 a.m. EDT)
Rapid-loading of the RP-1 tank has concluded with 9,700 gallons having been pumped into the rocket. Fine load is continuing.
0959 GMT (5:59 a.m. EDT)
The launch team has computed that the full load for the first stage fuel tank will be 9,901 gallons.

Once the tank is filled to the 98 percent level, or 9,700 gallons, the "rapid load" valve will be closed and the slower "fine load" phase will continue to top off the tank.

Судя по метеорадару, шансы улететь сегодня постепенно смывает дождём. Уже поставили в конец окна, на 12:59 GMT.

[Брабонт]

Начали заправку окислителем.

1150 GMT (7:50 a.m. EDT)
A bright white plume of vapors have begun streaming from a vent on the rocket and the bottom of the vehicle is icing over as the super-cold liquid oxygen continues to flow into the first stage.
1145 GMT (7:45 a.m. EDT)
Now 10 minutes into this approximate 25-minute process to fill the first stage liquid oxygen tank.
1135 GMT (7:35 a.m. EDT)
LOX loading begins! Cryogenic liquid oxygen, chilled to Minus-298 degrees F, has started flowing from the storage reservoir at Complex 17, through plumbing and into the bottom of the Delta 2 rocket. The LOX will be consumed by the first stage main engine during the first four-and-a-half minutes of flight along with the 10,000 gallons of RP-1 kerosene already loaded aboard the vehicle.
1131 GMT (7:31 a.m. EDT)
The concern about rain showers hitting the pad during tanking has diminished. And so the official "go" has been given by the launch director to start filling the rocket's first stage with liquid oxygen.

The anvil and cumulus clouds around remain "no go" for launch. But forecasters say those conditions should clear in the next hour.
1125 GMT (7:25 a.m. EDT)
The countdown has been recycled to target the 8:59 a.m launch time. Clocks now read T-minus 84 minutes and counting. There will be a 10-minute planned hold at the T-minus 4 minute mark.
1121 GMT (7:21 a.m. EDT)
NEW LAUNCH TIME. Liftoff is being retargeted for 8:59 a.m. EDT. That's the end of the today's available launch window.
1119 GMT (7:19 a.m. EDT)
To recap, the team has gotten the prep work done for loading liquid oxygen but stopped just short of actually starting the process to flow the cryogenic oxidizer into the rocket. Although it's not raining at the pad right now, there's showers around the Cape and uncertainty about the weather.
1114 GMT (7:14 a.m. EDT)
With still some rain showers to the north and south of the launch pad, the decision has been made to again delay the start of liquid oxygen loading.
1109 GMT (7:09 a.m. EDT)
The launch team has received approval to begin preparations for loading the rocket's first stage liquid oxygen tank.
1050 GMT (6:50 a.m. EDT)
Dawn is beginning to break here at Cape Canaveral. A light drizzle continues to fall and liquid oxygen loading has been pushed back. NASA says weather is the primary reason for the delay in the morning's launch to 8:39 a.m. EDT.
1044 GMT (6:44 a.m. EDT)
The countdown has been recycled to target the 8:39 a.m launch time. Clocks now read T-minus 105 minutes and counting. There will be a 10-minute planned hold at the T-minus 4 minute mark.

1224 GMT (8:24 a.m. EDT)
The launch team is beginning the "slew" or steering checks of the first and second stage engines. These are gimbal tests of the nozzles on the first stage main engine and twin vernier engines and second stage engine to ensure the rocket will be able to steer itself during launch.
1220 GMT (8:20 a.m. EDT)
A wall of towering clouds fills the eastern horizon, slowly marching toward the coast.
1214 GMT (8:14 a.m. EDT)
The checks of the rocket's safety systems are underway. That will be followed a short time from now by engine steering tests.
1210 GMT (8:10 a.m. EDT)

1206 GMT (8:06 a.m. EDT)
Meteorologists are watching the next area of weather inbound toward the Cape that has the potential to develop into characteristics that would violate the cumulus cloud rule starting around 8:30 a.m.
1200 GMT (8:00 a.m. EDT)
Loading of the Delta 2 rocket's first stage liquid oxygen tank has been accomplished. The filling process took 25 minutes and 31 seconds, ending at 8:00 a.m. The tank will be replenished through the countdown to replace the super-cold liquid oxygen that naturally boils away.

The rocket now stands fully fueled for liftoff. The vehicle's first stage was successfully loaded with RP-1 kerosene fuel along with the liquid oxygen this morning. The second stage was filled with its storable nitrogen tetroxide and Aerozine 50 fuels on Sunday. The nine strap-on booster rockets use solid propellants.
1159 GMT (7:59 a.m. EDT)
Now 60 minutes away from the planned launch time for the Delta 2 rocket and the STSS Demo spacecraft.
1158 GMT (7:58 a.m. EDT)
The first stage liquid oxygen tank just reached the 95 percent full level. The "rapid load" valve was closed, with the slower "fine load" phase continuing to fill the tank.
1157 GMT (7:57 a.m. EDT)
The cumulus cloud rule is back in a "go" for launch status. However, the anvil cloud rule remains "no go" at the curren time.

1232 GMT (8:32 a.m. EDT)
The weather officer says the forecast is "looking grim" given clouds around the Cape and today's launch window closing at 8:59 a.m. EDT.
1231 GMT (8:31 a.m. EDT)
Now both cumulus and anvil cloud rules are "no go" for a launch.
1230 GMT (8:30 a.m. EDT)
The first stage engine steering checks just finished. Technicians will take the next few minutes to review the data from the tests.
1227 GMT (8:27 a.m. EDT)
The second stage engine slews are complete. First stage tests have begun.

[Salo]

1239 GMT (8:39 a.m. EDT)
The rocket and payloads remain in good shape for launch. But the weather is unacceptable and meteorologists aren't sure conditions will improve in time for 8:59 a.m. EDT launch. That is the last moment of today's available launch opportunity.
1235 GMT (8:35 a.m. EDT)
Countdown clocks are continuing to the T-minus 4 minute mark where a 10-minute built-in hold is planned, leading to the target liftoff time of 8:59 a.m. EDT.

[Salo]

1245 GMT (8:45 a.m. EDT)
T-minus 4 minutes and holding. The countdown has entered the final planned hold point for today's launch. If the weather doesn't somehow clear up, the launch team will run out of window to get the rocket airborne today.
1244 GMT (8:44 a.m. EDT)
The weather officer reports to the launch team that current conditions are "no go" for anvil and cumulus cloud rules.

SCRUB. Inclement weather moving ashore from the Atlantic Ocean has forced today's launch of the Delta 2 rocket from Cape Canaveral to be postponed. The next launch opportunity will be tomorrow morning at 8 a.m. EDT.

[Salo]

1258 GMT (8:58 a.m. EDT)
A gradual improvement in the weather situation is expected over the next couple of days. There's a 30-40 percent chance of weather again preventing launch tomorrow and 30 percent or less on Friday, the weather officer just told mission managers.

The launch time outlook for tomorrow includes scattered cumulus clouds at 3,000 feet, isolated coastal showers, good visibility, easterly winds of 10 knots and a temperature around 76-78 degrees F.
1253 GMT (8:53 a.m. EDT)
Draining of liquid oxygen from the first stage after today's scrub is starting.

THURSDAY, SEPTEMBER 24, 2009
DELAY. Launch of the Delta 2 rocket carrying a pair of experimental missile-tracking satellites has been postponed an additional 24 hours due to a small fuel leak at the pad.

Liftoff from Cape Canaveral's pad 17B is retargeted for Friday morning at 8 a.m. EDT.

"Following Wednesday morning's weather launch scrub, teams detected a small leak in a flange in the fuel transfer system under the launch pad," a NASA spokesman says.

"Teams plan to assess the fuel leak and determine what steps to take to support the next launch attempt."

NASA says the Delta 2 rocket and the STSS Demo spacecraft remain in good condition with no technical issues.
