The Antares rocket is now powered on as the countdown continues. The weather outlook still calls for a 45 percent chance of acceptable weather conditions, according to Orbital Sciences.

1656 GMT (12:56 p.m. EDT)
There are no issues being worked in the countdown at this point, but officials continue watching the weather. Alignment of the Antares rocket's guidance and navigation system is now underway, chilldown of the main sub-cooler with liquid nitrogen is complete, and the launch team is "go" for prelaunch processing.

The odds of acceptable weather conditions at launch have improved to 55 percent.

WEDNESDAY, APRIL 17, 2013
1802 GMT (2:02 p.m. EDT)
The launch team has begun the process of priming the plumbing on the launch facility for loading of super-cold liquid oxygen, which begins at about 3:30 p.m. EDT (1930 GMT).

High-pressure gaseous nitrogen will also be used to purge the Antares propellant tanks before fueling.

In the next few minutes, the launch team will activate and test the flight termination system, which would be used to destroy the Antares launcher if something went wrong during launch.

WEDNESDAY, APRIL 17, 2013
1829 GMT (2:29 p.m. EDT)
Radio transmitter testing is complete on the Antares rocket, and the flight termination system tests are underway.

WEDNESDAY, APRIL 17, 2013
1930 GMT (3:30 p.m. EDT)
The launch team is awaiting a weather briefing on the current conditions and forecast around the Wallops launch site. Following the briefing, the team will decide whether to proceed with the next step in the countdown - fueling of the rocket with liquid propellants.

The start of fueling will restrict today's available launch window to 15 minutes. Officials are concerned an extended countdown would affect the temperature of the propellant.

The launch currently has a two-hour window extending until 7 p.m. EDT (2300 GMT).

WEDNESDAY, APRIL 17, 2013
1937 GMT (3:37 p.m. EDT)
The weather forecast is still iffy, and officials are closely watching low clouds north and west of the launch site. The ceilings there are below the launch limit of 6,000 feet, but conditions directly over the launch pad are still acceptable.

The launch team has given the "go" for propellant loading to begin in a few minutes.

WEDNESDAY, APRIL 17, 2013
1945 GMT (3:45 p.m. EDT)
Propellant is being pumped into the Antares rocket's first stage. About 21,000 gallons of RP-1, a high-refined rocket-grade kerosene, and about 41,000 pounds of liquid oxygen will be loaded into the first stage over the next half-hour.

The kerosene is stored at roughly room temperature and the liquid oxygen is chilled to minus 298 degrees Fahrenheit. The oxygen will slowly boil off during the countdown, and liquid oxygen continue flowing into the rocket until shortly before liftoff.

The first stage tanks are designed by Yuzhnoye and built by Yuzhmash in Ukraine based on heritage from the Zenit rocket. The liquid oxygen tank is positioned in the upper part of the 12.8-foot-diameter stage and the RP-1 tank is in the lower part of the stage.

The first stage's two AJ26 engines will consume the liquid propellant during a 3-minute, 50-second burn.

The Antares second stage, a Castor 30 motor built by ATK, is propelled by solid fuel already loaded into the rocket.

With the start of fueling, the available launch window has been shortened to 15 minutes. This is to keep the temperature of the propellant within acceptable limits, according to Mike Pinkston, Orbital's Antares program manager.

After chilldown begins at T-minus 30 minutes, the window will be limited to 10 minutes. After passing the T-minus 10 minute point, the launch window is again shortened to just 3 minutes.

WEDNESDAY, APRIL 17, 2013
2002 GMT (4:05 p.m. EDT)
The transporter-erector-launcher system, essentially a mobile launch tower next to the rocket, is configured to pull back from the launch vehicle, the launch team reports. The tower will retract a few degrees away from the rocket in the final seconds of the countdown.

Настолько подчёркивают, что оно US capabilities, что даже немножко стыдно. Ни Украина, ни made in USSR НК-33 пока не упомянуты никак.

О, упомянули Южмаш!

"Южмаш" упомянули только что.

И про НК-33. Ну ваще, что делается.

Fueling operations continue to go well. This is the first launch for both Orbital Sciences Corp. and NASA's Wallops Flight Facility to utilize liquid propellants.

"Wallops has been here 68 years and launched some 16000 rockets," said Bill Wrobel, director of Wallops Flight Facility. "This one is, no doubt, by far, the largest thing to ever come off the island."

Orbital Sciences has launched more than 1,000 space missions, including satellites, missiles and its Pegasus, Taurus and Minotaur satellite launch vehicles. All its rockets so far have been solid-fueled.

"It's going to be the biggest, brightest and loudest thing that's ever launched form Wallops," said Frank Culbertson, executive vice president and general manager of Orbital's advanced systems group.

Wallops regularly launches suborbital sounding rockets for scientific and engineering research purposes, and the facility has occasionally launched small satellites with Orbital Sciences Minotaur rockets.

The Virginia Commercial Space Flight Authority owns the Mid-Atlantic Regional Spaceport, which oversaw development of the launch pad used by Antares. The Commonwealth of Virginia paid for about $80 million of the $120 million cost of the launch pad, with most of the rest of the funding coming from the federal government.

The launch team is loading the flight trajectory file into the Antares flight computer.
