WALLOPS ISLAND, Va. — A new private rocket called Antares is poised to blast into space for the first time today, potentially marking a giant leap forward for the emerging commercial spaceflight industry.

Antares is slated to lift off at 5 p.m. EDT (2100 GMT) Wednesday (April 17) from Virginia's Mid-Atlantic Regional Spaceport (MARS), on a test flight designed to pave the way for unmanned cargo missions to the International Space Station.

If all goes well today, two different private American spacecraft could soon be delivering supplies to the orbiting lab for NASA — a scenario the agency envisioned five years ago, when it signed billion-dollar cargo deals with SpaceX and Antares' builder, Virginia-based Orbital Sciences Corp.

"A lot of people say that the American space program is in decline," Phil McAlister, NASA's director of commercial spaceflight development, said Tuesday (April 16) from the agency's Wallops Flight Facility, where MARS is located. "Well, you only have to go a couple of miles down the road to see it on the rise, literally."

Today's test flight will mark the biggest rocket ever to fly from Virginia's Eastern Shore and Wallops Island, which is NASA's launching ground for small sounding rockets. It could be visible from a wide swath of the U.S. East Coast, reaching as far north as Portland, Maine, and as far south as Charleston, S.C.

"This is a big event for the Eastern Shore for Wallops, and for everybody in the surrounding area and, I think, for everybody in the country," Orbital CEO and President Frank Culbertson told reporters Tuesday (April 16).


Filling the space shuttle's shoes

NASA is counting on Orbital and SpaceX to fill the cargo-carrying void left by the retirement of the agency's space shuttle fleet, which was retired in 2011 after 30 years of spaceflight.

Orbital signed a $1.9 billion contract with NASA to fly eight unmanned supply missions using Antares and a spacecraft called Cygnus under the space agency's Commercial Resupply Services program. California-based SpaceX got $1.6 billion for 12 flights with its Falcon 9 rocket and Dragon capsule.

SpaceX has already flown two of these contracted missions, delivering cargo to the orbiting lab in October 2012 and then again this past March. Dragon also visited the station on a demonstration flight in May of last year.

Orbital plans to be up and running soon as well. NASA picked Orbital as one of its cargo carriers in 2008 under a separate Commercial Orbital Transportation Service program, awarding the company $288 million to help develop the Cygnus spacecraft. At the time, Orbital was developing the Antares rocket in-house and added several hundred million of its own funds for the project, company officials said.

Orbital Sciences is already prepping a Cygnus for a demonstration mission to the space station, which could blast off by late June if today's Antares launch goes smoothly. The first official Cygnus cargo mission could then follow by year's end.

"It's being sent off to the fueling facility to get fueled, because the cargo's already packed," said Orbital spokesman Barron Beneski, explaining that Cygnus will carry about a half-load of cargo up to the station on the test flight.

The progress made by both SpaceX and Orbital shows that NASA's decision to rely on commercial cargo providers was a good one, Beneski added.

"I think it validates the approach that NASA has taken," he told SPACE.com. "For the government, I think this is a very good business deal on their part."

NASA also wants private American spaceships to start carrying its astronauts to and from the orbiting lab by 2017, ending its current reliance on Russian Soyuz spacecraft for this taxi service.

SpaceX is working on a manned version of Dragon in the hopes of scoring a NASA crew contract. Other major contenders are Boeing and Sierra Nevada Corp., which are developing a capsule called the CST-100 and a space plane called Dream Chaser, respectively.

"I think what this shows you is that there's no one way to do spaceflight development. There's no one business case," McAlister said. "There are multiple approaches and multiple strategies and philosphies that can work. We have this competitive environment and they are free to innovate."



Antares' maiden launch

From start to finish, today's test flight will last about 18 minutes. It should take the Antares rocket, however, about 10 minutes to deploy its payload — a dummy version of the Cygnus spacecraft — after launch.

While Orbital is targeting a 5 p.m. EDT (2100 GMT) liftoff, the company has a three-hour window in which to launch the Antares rocket. Currently, there is about a 45 percent chance of good weather at launch time. The potential for thick low clouds — NASA has a visibility requirement for the flight — and rainstorms are the only concerns. Orbital would try again on Thursday (April 18) if weather delays today's flight.

The Antares rocket is a two-stage booster that stands about 131 feet (40 meters) tall and is powered by two Aerojet AJ26 liquid-fueled engines that are modernized versions of engines originally built to launch Russia's N-1 moon rocket in the 1960s.The second stage is a solid-fueled rocket motor built by Alliant Techsystems (ATK), the same company that built the rocket boosters for NASA's space shuttles.

The rocket, Culbertson said, will appear to take its time launching off the pad before streaking spaceward on a southeastern trajectory that carries it out over the Atlantic Ocean. Since the launch will be visible from Washington, D.C., Orbital officials have provided viewing guides to members of Congress to help lawmakers see the launch, and will host an event at the company's office near the Capitol.

"'My confidence level is very high," Culbertson said. "I think we're going to see a nice show and I feel great."

The target orbit of the Antares rocket is a path that alternates between 155 miles (250 kilometers) and 188 miles (303 kilometers) above the Earth. The dummy Cygnus vehicle should stay in orbit for about two weeks before burning up in Earth's atmosphere, Culbertson said.

Before burning up, however, the Cygnus mass simulator will deploy three tiny satellites for NASA and a commercial client. The small nanosatellites include two versions of coffee cup-size Phonesats for NASA's Ames Research Center and the Dove-1 nanosatellite for a commercial customer.

Culbertson said today's launch will likely be the loudest rocket ever to blast off from Wallops Island, which is flanked by a national wildlife refuge.

"We'll try not to disturb the crabs and oysters," he said with a laugh.

I just might see it, way off low to my SSW (if I don't forget to look).

[Buster's Uncle]

Siiigh.  There was an outside chance I could've found a high enough vantage point to see over the trees if I was back home in America - but Mylochka's brain needs me here in Texas...

[Unorthodox]

LIve stream. 


NASA TV

[Buster's Uncle]

It's not the same...

[Unorthodox]

No. 

You're more likely to be able to see the interesting bits via the link than seeing it in person though.  I'm sure they'll be recorded, not sure they'll be on the live link. 

[Unorthodox]

Then I probably have a skewed sense of interesting. 

[Buster's Uncle]

You do, but you're not wrong about this.

[gwillybj]

Launch aborted for today. An umbilical detached prematurely from the second stage at 12 minutes before scheduled lift-off.

[Buster's Uncle]

I was in the bathtub anyway.

[Unorthodox]

 


Anyhow, possible attempt Friday. 

[Unorthodox]

Pushed to Saturday due to weather. 

[gwillybj]

It's good to delay the launch than to release it with bugs into an unfriendly atmosphere.

New Private Rocket's Maiden Launch Set for Saturday
By Mike Wall | SPACE.com – 17 hrs ago...


The critical test flight of a new private cargo-carrying rocket will come no earlier than Saturday afternoon (April 20) due to weather delays and a technical glitch.

The private aerospace firm Orbital Sciences Corp. had aimed to fly its Antares rocket Wednesday (April 17) from Virginia's Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, but a data cable separated from the booster earlier than planned, forcing officials to postpone the launch attempt just minutes before liftoff. Orbital initially considered trying again Friday (April 19) but nixed that idea because of weather concerns.

"Weather conditions deteriorate on Friday, April 19, but improve significantly over the next two days, increasing the chances for acceptable conditions at launch time," company officials said in a statement Thursday (April 18). "This also allows the Antares launch team a day of rest before back-to-back opportunities on Saturday, April 20 and Sunday, April 21." [See photos of Orbital's Antares rocket test]

The Antares rocket is now slated to launch Saturday at 5 p.m. EDT (2100 GMT) Saturday from MARS, which is located at NASA's Wallops Flight Facility. Antares' launch window runs through April 29, NASA officials said.

NASA TV will provide a live broadcast of the Antares launch online beginning at 4:30 p.m. EDT (2030 GMT) if a Saturday attempt goes forward. You can watch the Antares launch webcast live here at SPACE.com, courtesy of NASA.



Virginia-based Orbital Sciences is counting on the 131-foot-tall (40 meters) Antares rocket to launch its Cygnus spacecraft on unmanned cargo missions to the International Space Station. The company holds a $1.9 billion deal with NASA to make eight such flights.

This test flight — which Orbital is calling A-ONE — won't carry a Cygnus, and it won't go to the space station. Rather, it will loft a Cygnus "mass simulator," a mock payload filled with sensors to mimic the weight of a real spacecraft, to orbit to demonstrate Antares' capabilities.

A-ONE will also serve as a test of Antares' launch pad at MARS, known as Pad 0A. The pad was originally built for the now-defunct Conestoga rocket in 1995 but was completely refurbished to accommodate Orbital's new booster.

If all goes well with the A-ONE flight, Antares could blast Cygnus on a demonstration mission to the space station as early as late June, Orbital officials have said.

Orbital isn't the only company with a NASA cargo contract. California-based SpaceX signed a $1.6 billion deal to make 12 robotic flights with its Falcon 9 rocket and Dragon capsule. SpaceX has completed two of these contracted missions already, the first in October 2012 and the second last month.

Antares' maiden launch should put on a show for observers over a large stretch of the U.S. East Coast if clouds don't get in the way. Viewing maps released by NASA and Orbital suggest that liftoff could be visible from as far north as Portland, Maine, and as far south as Charleston, S.C.

Scrubbed today.  IIRC tomorrow's the last day of the launch window.
