Orbital Successfully Launches New Rocket

Orbital Sciences Corp. successfully launched its new rocket as part of a test flight for the National Aeronautics and Space Administration.

The two-stage rocket lifted off at 5 p.m. local time on April 21 from Wallops Island, Virginia. About 10 minutes later, it delivered a dummy payload into orbit. The booster, called Antares, is the Dulles, Virginia-based company’s newest and biggest, measuring 133 feet long with about 755,000 pounds of thrust.

The test flight was required before Orbital attempts to launch an unmanned cargo spacecraft, called Cygnus, to the International Space Station this summer. Orbital and Space Exploration Technologies Corp., known as SpaceX, have NASA contracts to resupply the station through at least 2018. They’re also marketing the rockets to defense and intelligence agencies as cheaper alternatives to those built by Lockheed Martin Corp. and Boeing Co.

“Today marked a giant step forward for the Antares program, with a fully successful inaugural flight of the largest and most complex rocket the company has ever developed and flown,” David Thompson, Orbital’s chief executive officer, said in a statement. “We will now move forward toward completing the full demonstration mission of our system to resupply the International Space Station with essential cargo in just a couple of months.”

NASA Administrator Charles Bolden in a news release called it a “picture-perfect launch.”

The mission ended about 18 minutes after liftoff when the rocket’s upper stage completed planned maneuvers to distance itself from the dummy payload, which was the same size and weight as the Cygnus spacecraft, Orbital said. The flight demonstrated “all operational aspects” of the rocket, including reaching the target orbit of about 150 by 160 miles, the company said.

The launch was previously scheduled for April 17. It was aborted with about 10 minutes left in the countdown when an upper-stage engine hose disconnected prematurely. Once planned for 2011, the mission was repeatedly postponed because of delays in building and inspecting the new $125 million launch pad on Wallops Island.

Antares is designed to launch spacecraft weighing up to 14,000 pounds into low-Earth orbit and lighter payloads into higher orbits. It will offer commercial and other government customers such as the Air Force “affordable and reliable” launch services for medium-sized satellites that don’t require larger, more expensive vehicles, the company said.

The rocket for its first stage uses two liquid-fuel AJ26 engines, made by Aerojet, part of California-based GenCorp Inc. They’re modified versions of the NK-33s built in Russia more than four decades ago for its moon program, which was later canceled. Aerojet bought about 40 NK-33 engines in the mid-1990s and, under a contract with Orbital, modified them specifically for Antares, according to Aerojet. The second-stage of the rocket uses a solid-fuel engine made by Arlington, Virginia-based Alliant Techsystems Inc.

Orbital, which also makes satellites, saw an opportunity for Antares amid the dwindling inventory of Delta IIs sold by Centennial, Colorado-based United Launch Alliance LLC, a joint venture of Bethesda, Maryland-based Lockheed Martin Corp. and Chicago-based Boeing Co.

The rocket may be a contender for such military programs as the Air Force’s Orbital/Suborbital Program-3, known as OSP-3, and Evolved Expendable Launch Vehicle, known as EELV. It’s already certified for the NASA Launch Services-2 contract, according to the company.

Orbital has a separate $1.9 billion contract with NASA for at least eight resupply missions to the space station. The agency is relying in part on Orbital and SpaceX, led by billionaire Elon Musk, to ferry food, water and supplies to the station after retiring its shuttle fleet in 2011. The agency also plans to begin ferrying astronauts to the station on commercial rockets beginning in 2017 so it can concentrate on manned mission to an asteroid and Mars.

“With NASA focusing on the challenging and exciting task of sending humans deeper into space than ever before, private companies will be crucial in taking the baton for American cargo and crew launches into low-Earth orbit,” John Holdren, director of the White House Office of Science and Technology, said in a statement following the test flight.

SpaceX, which has a $1.6 billion NASA agreement for at least a dozen cargo flights, was the first company to send a privately developed spacecraft to the orbital outpost. The Hawthorne, California-based company completed its demonstration mission to the space station last spring and its first regular flight in the fall. SpaceX finished its second regular mission in March.

SpaceX’s Dragon capsule is designed to bring back science experiments, lab equipment and other cargo, unlike Orbital’s Cygnus, which is designed to take back trash and burn up during re-entry.

    Hopefully these companies aren’t union based.

    “Dear SpaceX,

    I am interested in providing outsourcing opportunities for your company in Korea. Please send some example rockets and willing engineers to the Kaesong Industrial Complex. I will provide transport from there.

    My only problem with orbital is that it shows the typical Government Acusitions process, spend spend spend. For exapmle, Orbital replaced another company that had a contract along with SpaceX, but failed to meet some goals on time. Thats fine, but the problem is that Orbital is doing LESS launces for MORE money the SpaceX, AND they cant be used to return anything from the station. Seems to me that SpaceX is clearly the leader in terms of Bang for Taxpayer Buck, so why not just extend the contract wiht SpaceX to cover the remaining launches and save the money…..


      Yeah, the only trouble is that Defense Tech seems to love to ignore the leader, Space X. A truly remarkable company; though. Their development for the most powerful launched rocket ever (after the Saturn V) is reason enough to cover them.

      • John Deere

        SpaceX and Orbital Sciences are simply building on 60 years of taxpayer funded research; replicating NASA’s achievements from the Gemini era… All testing and launch facilities, personnel, craft/rocket designs, funding and “profits” come from NASA.


          You really have it in for Space X. They fact is that they are a private company, and through both private money and government money, they have been one the fastest growing space programs in HISTORY.

    As I understand it, Orbital is using refurbished Russian engines. Do they actually have the capacity to produce new ones if everything goes well when those run out?

    • NavyGuy2007

      Aerojet bought about 40 NK33s from Russia and modified them. I would assume that they can manufacture the modified version, AJ26, as needed now.

  • TrueBlood

    Haven’t heard of too many Union People selling secrets to our enemies. As a matter of fact I can’t recall a single one. GO Blue…Union tried and True. Oh thats right, its not patriotic to want to make a better life for myself and family, I must oblige myself to corporate outsourcing so only a few grredy american’s can benefit from hard work and the toils of labor./

    • NavyGuy2007

      I dont want to get into a Union debate, but some would argure that a few companies out source BECAUSE of Unions. Many Cities across the nation are going bankrupt due in large part to HUGE union pensions, one lady in California has a $430k a year pension comeing when she retires next year thanks to her union. The Unions in WA State were up in arms when Boeing built a 787 plant in SC and not Washington because SC is a Right to Work state, which is how I think it needs to be nation wide, if a person dosent think the need union representation at a company, they should not be fored into it or loose their job.

      The Former head of the DC Teachers Union on John Stossel last year said “The day students start paying dues I’ll worry about them.” The basic Structure is Union boss>Union>Member. I agree that Unions were needed back in the day, there was a LOT of bad pay and horriable conditions, but now that we have Worker protection laws, OSHA ect..I think that a lot of them are just corrupt and greedy.

      Just my .02 anyways…

      • TrueBlood

        Not to get into a full Union debate either. I thank the Unions for a 40 hour work week, paid vacations, paid sick days, representation if needed at arbitration, merit system boards, discipline hearings, affordable health care and so on. I also thank them heavily for keeping my job within the government instead of contracting or outsourcing them. I get really sick of old 1970’s rhetoric that is tossed out about how Union workers are over paid when in fact true labor wages within Unions are less than those companies with comparable contracts and labor commitments that operate in the U.S. Open source competition is good because it creates advances in short amounts of time and creates transparency. This is critical for budgets and tax payers. As a business major, Unions do define certain paramters, but agree they can damage the principles of why Union work, as a labor force. As a former Chief Steward within the Second largest Federal Union – I have seen dynamic changes in their approach and understanding. These changes have come about because they forced managment to become more transparent. Its easy to cause a force to look bad when you lie to them or keep information about their working environment conditions as a whole silent.

        • TrueBlood

          With education comes a more reliable contingent that you must deal with openly and honestly. I support my country and want to preserve it through all available protections sources including labor. Please take no offense at what I propose or stand for. United we accomplish more than if we are divided.

      • blight_

        I see you have noticed the one thing in common between “overpensioned unioners” and the “evil CEOs”:

        Both persons are people in authority compensating themselves /because they can/, regardless of the common interest of other employees.


          Yeah. Personally, I wish companies had people like good ole Ford at their helm. He would send people out to make sure that every factory worker of his was not drunk, late, and they each checked their homes for drink. Now, its a free-for-all. Of course, if a company did the service of making sure all its workers were straight, it would be brought up as a supreme court issue.

          • blight_

            The problem is that people who did not found a company have little interest in the company beyond its ability to give them a salary and stock options. Who cares about the workers? Or the product, up until it kills the company?

          • USS ENTERPRISE

            Yeah. Well, mostly. I mean, Kelly Johnson wasn’t like that (he held probably the most important bits of Lockheed, so don’t tell me he wasn’t CEO or something). Its rare to find people like him, as companies hire business men to lead companies, rather than hard working engineers.

          • blight_

            His title was Chief Engineer, wasn’t it? He didn’t lead the company and probably would’ve hated it. He wanted to design wonderful aircraft. He got his wish. He did mass production aircraft for WW2, but spent the Cold War on boutiques.

      • John Deere

        Only 6% of the US workforce is unionized. They have no effect on US economic performance, despite the nonsense you hear spouted by some political figures.

  • Stan

    The first stage is manufactured in Russia (or Ukraine) and the Cygnus vehicle is manufactured in Italy. Engines Russian-made for now and Russian-designed forever. Pricing per pound probably as insane as charged by ULA even if lunch winds up being cheaper due to smaller rockets. Government money well spent.

  • Belesari

    Stop deleting my post Dtech.

    SpaceX is currently developing a reusable system making it fully reusable. It also has its own spacecraft. New Engines will power the future Falcons even more efficiently and more powerfully than the present. All American made and mass produce engines able by design.

    SpaceX has probably done this cheaper than Orbital or any other. Damn sure cheaper than any other government project has. They are in a whole other league.

  • David

    Amusing to see the SpaceX fanbois coming out. Reminiscent of Apple vs. Microsoft, with SpaceX = Apple and Orbital = Microsoft.


      Well, Apple is better. And have you seen the progress Space X has?

  • bobbymike

    Solid fuel version would make a nice sized ICBM and Global Strike Missile

  • Some old fashioned american rubbish!
    No single-stage-to-orbit plan yet, usa?
    Oh dear!
    SABRE, the latest British invention that you’ll try to steal, is coming!
    Yet again, the British teach the usa how to take some steps toward the 21st century!

    Go feed your horse, cowboy! Or fix your dollar. Or pay your debts?
    Leave space to the real people… the ones who made your Interent useful after being useless in american hands for 50yrs, invented the computer and gave you the jet engine!

    No, don’t thank us, usa. You’ll can that when nobody is using your dollars to transact.
