ЦитатаThe launch of the Air Force's Delta 4 Wideband Global SATCOM 3 (WGS 3) mission is now targeted for December 5 with a launch window of 7:23-8:47 p.m. EST.

After evaluating the situation, mission managers believe this will give the launch team the time required to replace an electronics card that is part of the ground equipment used to monitor telemetry data from the Delta 4 and related systems for the launch. An anomaly with this monitoring system hardware led to the scrub of the first launch attempt December 3.

ЦитатаFRIDAY, DECEMBER 4, 2009
After resolving a minor technical glitch and waiting out rainy weather, the Delta 4 rocket is targeting a Saturday evening blastoff from Cape Canaveral to deploy a sophisticated communications satellite for the U.S. military.

Liftoff from Complex 37 will be possible during an 84-minute window extending from 7:23 to 8:47 p.m. EST (0023-0147 GMT).

Air Force officials said late Friday that the faulty electronics card has been replaced in a piece of ground support equipment used to monitor telemetry data. The issue arose during Thursday's countdown, ultimately leading to the launch postponement.

A gloomy weather forecast caused Wednesday's original launch opportunity to be scrapped in advance and unfavorable conditions were a problem during Thursday's countdown as well. Persistent rain fell all day on Friday and meteorologists are giving only 40 percent odds of acceptable weather during Saturday night's try.

Once the rocket does fly, it will perform a 40-minute ascent to supersynchronous transfer orbit to launch the Air Force's third Wideband Global SATCOM communications spacecraft, known as WGS 3.

WGS satellites are giving a major upgrade to the military's main communications infrastructure, replacing the aging Defense Satellite Communications System spacecraft. Each WGS has 10 times the capacity of a DSCS satellite, allowing users to process and receive data quicker than ever before.

The new WGS 3 satellite will be positioned above the Eastern Atlantic at an orbital slot of 12 degrees West longitude to serve the U.S. European Command and U.S. Africa Command, plus lend additional support over the Middle East.

WGS 1 entered service last year to cover the vast Pacific Command that spans the U.S. western coast all the way to Southeast Asia. The WGS 2 satellite launched earlier this year was placed into operation over the Indian Ocean for use by U.S. Central Command to provide coverage for the warfighters in Afghanistan, Iraq and other parts of Southwest Asia.

ЦитатаDelta 4 rocket aims for Saturday night launch

After resolving a minor technical glitch and waiting out rainy weather, the Delta 4 rocket is targeting a Saturday evening blastoff from Cape Canaveral to deploy a sophisticated communications satellite for the U.S. military.
Цитата1345 GMT (8:45 a.m. EST)
The second launch attempt is officially underway at Cape Canaveral today for the Delta 4 rocket that will place the third Wideband Global SATCOM military satellite into Earth orbit.

Ground technicians have rolled the 330-foot tall mobile service tower away from the rocket, retracting the wheeled structure along rail tracks to its launch position about the length of a football field away from the Delta 4. The 9-million pound tower shielded the rocket from the elements during the stay on the pad, provided workers 360-degree access to the various areas on the vehicle and was 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.

Liftoff remains scheduled for 7:23 p.m. EST.

T-minus 5 hours, 15 minutes and counting! The Terminal Countdown has commenced for this evening's scheduled launch of the Delta 4 rocket to deliver a new communications satellite into orbit for the United States military.

The countdown has one planned built-in hold at T-minus 5 minutes lasting some 15 minutes, leading to liftoff at 7:23 p.m. EST (0023 GMT).

The launch pad has been verified evacuated of all personnel in advance of fueling the rocket's two stages this afternoon. Pad systems and equipment stand ready for fueling activities, which should kick off shortly.
 
1843 GMT (1:43 p.m. EST)
Checks of the C-band beacon are beginning. This system is used in tracking the rocket during the flight downrange.

1839 GMT (1:39 p.m. EST)
The launch team has been polled to verify all consoles are manned and ready to begin the Terminal Countdown when this hold ends at 1:53 p.m. A briefing on countdown procedures is now underway.

1835 GMT (1:35 p.m. EST)
The weather officer says the thick clouds and rain have moved to the south and east of Complex 37, giving more optimism about the chances for a launch today.

It remains a gloomy overcast sky at the Cape. But meteorologists report the low clouds are thin and not violating any of the weather criteria. At the present time, the weather is "go" for launch.

The main worry for this evening will be the winds. Overall, the odds of acceptable weather during the 7:23 to 8:47 p.m. EST launch window have improved to 60 percent.

The revised launch forecast calls for some broken decks of clouds at 4,000 and 8,000 feet, good visibility, northwesterly winds of 15 peaking to 20 knots and a temperature around 56 degrees F.

The outlook for Sunday night, if the launch should slip 24 hours for some reason, is 80 percent favorable with lighter winds and scattered clouds.

1808 GMT (1:08 p.m. EST)
The call to "man stations for Terminal Count" just went out to the launch team.

1753 GMT (12:53 p.m. EST)
T-minus 5 hours, 15 minutes and holding. The countdown has just entered a planned 60-minute built-in hold, giving the team time to catch up on any work that could be running behind schedule. Once the clocks resume ticking at 1:53 p.m. EST, the Terminal Countdown phase of today's launch operation will begin.

1725 GMT (12:25 p.m. EST)
Here's some fresh photos taken this morning at pad 37B as the second launch attempt began. See the gallery.

1700 GMT (12:00 p.m. EST)
The cold front passed over the launch site a short time ago, producing some wind gusts around 29 knots as a light, constant rain continues to fall over the Space Coast.

But the launch weather officer says with the front now moving on southward, the winds should settle down this afternoon to the 20-22 knot range and the rain will end.

For the rest of the countdown and this evening's launch window, the concerns will be the thickness of the clouds overhead and surface winds hovering around the liftoff constraint of 20 knots.

Meteorologists are hopeful that the clouds will thin and scatter out this afternoon and they'll be keeping a close eye on the wind speeds at the pad.

Цитата2223 GMT (5:23 p.m. EST)
Launch of the Delta 4 rocket with the third Wideband Global SATCOM spacecraft is just two hours away.

The first two WGS satellites were hauled into space aboard Atlas 5 rockets. But WGS 3 is riding atop the Delta 4, the other rocket in the Air Force's Evolved Expendable Launch Vehicle fleet. Both vehicles are produced by United Launch Alliance, the firm created three years ago this month that joined Lockheed Martin's Atlas and Boeing's Delta rockets under one organization.

"This mission is symbolic of why ULA formed for a couple of reasons," says James Bell, ULA's WGS mission manager.

"First, it exemplifies why the government brought the Atlas and Delta programs together. The first two WGS satellites were launched on our Atlas vehicles and for WGS 3, instead of our Delta 4 team having to start from scratch, ULA was proactive in implementing a seamless integration and processing services for this repeat customer.

"Also, because I was the WGS mission manger for those two Atlas launches, I was able to share the knowledge we gained from those launches with our Delta team. This is not only a tremendous benefit for ULA but also for our Air Force mission partners who are relying on us to provide them assured access to space. This simply wasn't possible prior to ULA.

"Second, this mission marks the 36th launch for ULA in 36 months, which is quite a record of reliability and mission success. When ULA was formed, our primary goal was to provide safe and reliable assured access to space with mission success paramount in everything we do."

2219 GMT (5:19 p.m. EST)
The upper stage liquid oxygen tank has been filled up, now making the Delta 4 a fully fueled rocket.

2209 GMT (5:09 p.m. EST)
For the first time in a couple of days at the Cape, the clouds are giving way to the sun. This low overcast is sliding out!

2157 GMT (4:57 p.m. EST)

2140 GMT (4:40 p.m. EST)
A status check of the fueling activities shows the fast-fill loading to the upper stage liquid hydrogen tank just ended. The launch team continues to load the liquid oxygen supply to the stage.

2123 GMT (4:23 p.m. EST)
The upper stage conditioning on the liquid oxygen side has finished. Loading of the tank is starting. This is the last of the rocket's four cryogenic supplies to be filled in today's countdown to launch.

2115 GMT (4:15 p.m. EST)
Post-filling tests on the first stage liquid oxygen system are complete and the tank is going into topping mode.

2112 GMT (4:12 p.m. EST)
The official launch weather forecast has removed the concern for thick clouds for tonight. A line of clearing is making its way toward the Cape, there's no rain in the area and the surface winds remain below limits.

The upper wind conditions are being closely watched, however, due to a strong wind shear up through 15,000 feet. A pre-planned series of weather balloons will be released throughout the countdown to monitor the direction and speed of the winds for engineers to select the best flight profile for launch.

2107 GMT (4:07 p.m. EST)
After finishing up work on the first stage liquid oxygen side, the launch team is moving into the chilldown procedures for the upper stage liquid oxygen system.

This launch will deliver to orbit the third satellite in the Wideband Global SATCOM series. Although more spacecraft are under construction in the Block 2 phase of the program, today's deployment of WGS 3 marks the last satellite in Block 1.

"The upcoming launch of WGS is really a landmark achievement for the DOD and The Boeing Company. It completes the initial constellation of three WGS satellites that will provide vital, flexible, high-capacity communications to the U.S. warfighters and allies across the theaters of operation," said Mark Spiwak, the WGS program director at Boeing.

Boeing shipped the WGS 3 satellite from its factory in El Segundo to Cape Canaveral on September 28. Over the past two months, the craft underwent final testing, fueling and encapsulation in the shroud that will cover it during launch.

On November 14, the spacecraft was transported from the Astrotech processing facility in Titusville to Complex 37 where it was hoisted atop the Delta 4 rocket.

"It's ready to join its brothers in arms -- WGS 1 and 2 -- in providing this capability to the men and woman of our armed forces. We look forward to a great ride from ULA," said Spiwak.

The company has three additional WGS satellites currently in production for launches slated to start in 2011.

"On behalf of The Boeing Company, we are very proud to be providing them to the United States Air Force. They are a key element in the very highly flexible and capable system providing this quantum leap in communications for the warfighter."
