Decision on new Orbital ATK rocket expected in 2018

The competition heats up? Orbital ATK says it will decide whether it will introduce a new commercial rocket sometime in early 2018.

Orbital ATK has released few details about what is known only as its “Next-Generation Launcher.” The vehicle would use solid-fuel lower stages based on space shuttle solid rocket motor segments developed by the company, as well as solid strap-on boosters. A liquid-oxygen, liquid-hydrogen upper stage would use a version of Blue Origin’s BE-3 engine that company is currently flying on its New Shepard suborbital vehicle.

The rocket’s design has at least superficial similarities to a vehicle concept called Liberty that ATK proposed prior to its merger with Orbital Sciences Corporation. Liberty, with a five-segment shuttle solid rocket booster first stage and a second stage derived from the Ariane 5 core stage provided by Astrium, was itself a commercial spinoff of the cancelled Ares 1 rocket from NASA’s Constellation program. ATK proposed Liberty for NASA’s commercial crew program but failed to win funding.

The decision itself will be based on whether the Air Force remains interested. At the present time the Air Force is investing about half the capital required to develop the rocket. If the Air Force backs out, Orbital ATK will decide against the rocket. If the Air Force support remains firm, they will go ahead with development. Essentially, this story is Orbital ATK lobbying to keep the Air Force support going.

Orbital ATK prepares Cape Canaveral launchpad for July Minotaur launch

The competition heats up: Orbital ATK crews on Sunday practiced stacking stages on a Cape Canaveral launchpad in preparation for a July Minotaur 4 launch of an Air Force surveillance satellite.

Teams this weekend stacked three inert Peacekeeper missiles stages on a launch stand similar to those that will make up the Minotaur IV rocket’s first three stages. Two more Orion 38 stages will fill out the rocket. On Sunday, the first three stages standing more than 50 feet tall were surrounded by puffy white covers that will keep the right temperature during the launch campaign’s summer heat.

Plans called for the mobile gantry to be rolled back on rails to its launch position before the stages are taken down on Monday.

Orbital ATK has been prevented from expanding its Minotaur 4 market beyond military launches because the rocket uses these available but now unused Peacekeeper missiles and is thus very inexpensive. Their competitors have been their influence in Congress to forbid their use commercially.

Orbital ATK sues DARPA over its satellite repair program

Orbital ATK has filed a lawsuit against the Defense Department’s DARPA division over its satellite repair program that is apparently going to award a contract to a Canadian company to develop a system for using robots to repair orbiting satellites.

Orbital argues that the federal program, called the Robotic Servicing of Geosynchronous Satellites, would unfairly compete with its own privately funded effort, a system called the Mission Extension Vehicle 1, backed by at least $200 million from investors. The company has set up at a production facility in Northern Virginia, with a launch planned for next year.

DARPA wants to build out a government-funded program of its own, and is close to awarding a contract to a company that Orbital views as a competitor. In a contract announcement briefly posted on the agency’s website, DARPA said it is awarding a $15 million contract to Space Systems/Loral (SSL), a U.S. subsidiary of Canadian aerospace firm MacDonald, Dettwiler and Associates. DARPA spokesman Jared B. Adams said the contract award was posted in error and elements of the deal are still being worked on.

In its lawsuit, Orbital alleges that the contract violates federal policy against creating government space programs that compete with existing commercial ones. “The U.S. National Space Policy explicitly directs government agencies to avoid funding activities that are already in development in the commercial marketplace,” the company said in a statement. “Orbital ATK will continue to pursue all available options to oppose DARPA from moving forward with this illegal and wasteful use of U.S. taxpayer dollars.”

DARPA normally pushes projects that no one is doing, either because the work is too experimental or can’t yet make a profit. In this case however it appears that this is not the case. Worse (from a political perspective), they are awarding the contract to a non-American company. I would not be surprised if Congress soon steps in and shuts this particular DARPA project down.

Orbital ATK’s Pegasus launches successfully

Orbital ATK’s Pegasus rocket was successfully launched today from the bottom of its L-1011 airplane, placing in orbit a NASA constellation of eight smallsat satellites designed to study hurricanes.

he use of an eight-satellite constellation will allow for more frequent observations, allowing for a better characterization of the early stages in a cyclone’s formation and of the storm’s eventual decay. Once in orbit, the satellites will be spaced evenly around their orbital plane, achieving an angular separation of around 45 degrees from each other. The CYGNSS satellites were built by the Southwest Research Institute and the University of Michigan, while their deployer was developed by Sierra Nevada Corporation. Each satellite has a mass of 28.9 kilograms (63.7 lb), with an overall payload mass of 345.6 kilograms (761.8 lb) including the deployer. The CYGNSS mission is expected to last a minimum of two years.

This was the first Pegasus launch since 2013. I’m not sure why it has not been getting more business, but it does have another launch now scheduled for June.

Cygnus fire experiments a success

The fire experiments that were done on the Cygnus cargo freighter after it left ISS two weeks ago have been declared a success.

Saffire-II burned nine different samples, in an effort to gauge the flammability of various materials in a microgravity environment. These 12-by-2-inch (30 by 5 centimeters) samples included silicon of different thicknesses; a cotton-fiberglass blend; plexiglass; and Nomex, a commercially available material that’s used in spacecraft on cargo bags and as a fire barrier, NASA officials said. Everything went well during the experiment, they added: All nine samples burned as planned, and the Saffire-II team collected more than 100,000 images. All data had come back down to Earth by Friday (Nov. 25), at which point Saffire-II achieved “complete mission success,” NASA officials wrote in an update.

This was the second set of fire tests. There are plans for a third on a future Cygnus freighter.

Atlas 5 to launch Cygnus in March

NASA has ordered Orbital ATK to use ULA’s Atlas 5 rocket for its next Cygnus cargo run to ISS in order to maximize the cargo that the capsule can deliver.

A Cygnus reached the station last month with over 5,000 pounds of supplies after launching atop Orbital ATK’s own Antares rocket. It was the first such flight for the booster in two years, a lull instigated by the 2014 explosion of an Antares and Orbital ATK’s decision to replace the main engines with a different design. But the more-powerful Atlas 5 rocket can launch over 7,700 pounds of provisions inside a Cygnus, and the Wall Street Journal reported on Thursday night that NASA has pushed Orbital ATK to buy another Atlas 5 for its greater lift capacity and reliability record.

Sources told Spaceflight Now that the Atlas 5 would launch the OA-7 mission in March and that Orbital ATK was working with Kennedy Space Center to book facility time to process the Cygnus.
It was not immediately clear if NASA or Orbital ATK would pay for the extra costs associated with the Atlas 5 rocket.

This decision by NASA to favor Atlas 5 here over Antares illustrates some of the commercial weaknesses of Antares. Orbital ATK’s decision to launch the rocket from Wallops Island in Virginia had some political advantages, putting their launch facilities in the state and congressional district of legislators whose approval they were soliciting. The decision, however, limited the cargo capacity of the rocket because of the site’s higher latitude. This might also help explain why Orbital ATK has as yet failed to find any other customers for Antares, besides NASA.

I also wonder whether some political pressure from other legislators who favor ULA also helped influence this decision. The political game is brutal these days in Washington and almost nothing connected to the federal government is done anymore without some crony and corrupt political maneuvers in the background.

Antares successfully launches Cygnus

After two years of redesign, Orbital ATK’s Antares rocket tonight successfully put a Cygnus cargo capsule into orbit.

Considering that every single one of the vehicles that fly to ISS (Soyuz, Dragon/Falcon 9, Cygnus/Antares, HTV) has been experiencing some issue that has delayed each of their launches, this success tonight must be a relief to managers and engineers in both Russia and the U.S.

Next comes a manned Soyuz launch on Wednesday.

Russia gets two contracts for Proton

The competition heats up: Russia has signed two new contracts using its newly announced Proton-Medium rocket configuration.

Both contracts are for the same launch. The primary payload will be a Intelsat communications satellite. The secondary payload will be Orbital ATK’s first Mission Extension Vehicle (MEV-1), which is actually more significant and somewhat ground-breaking.

The MEV-1 provides life-extending services by taking over the propulsion and attitude control functions. Satellites have an average of 15 years of life on orbit, before they need to be replaced. The vehicle itself has a 15-year design life with the ability to perform numerous dockings and undockings during its life span. “Rather than launching new satellites, operators can extend the life of healthy in-orbit satellites, providing enhanced flexibility through Orbital ATK’s scalable and cost-efficient capabilities,” noted Our simple approach minimizes risk, enhances mission assurance, and enables our customers to realize the maximum value of their in-orbit satellite assets.”

The launch of MEV-1 will involve in-orbit testing and a demonstration to be performed with an Intelsat satellite. MEV-1 will then relocate to the Intelsat satellite scheduled for the mission extension service, which is planned for a five-year period. Intelsat will also have the option to service multiple satellites using the same MEV.

If MEV-1 proves successful, Orbital ATK will have built, launched, and made money from the first robot repair satellite. While at first glance this success suggests that satellite companies will need to launch fewer satellites, thus reducing the market demand for rockets, what it will really do is make the orbiting satellite more useful and profitable, thus encouraging new players to enter the market. The demand for satellites will increase, thus increasing the demand for rockets.

Ain’t freedom and private enterprise grand?

Stratolaunch to use Orbital ATK’s Pegasus rocket

The competition heats up? Vulcan Aerospace and Orbital ATK announced today that they are renewing their partnership, using Pegasus in conjunction with Stratolaunch to put satellites into orbit.

Under a multiyear “production-based partnership,” the companies said, Orbital ATK will provide “multiple” Pegasus XL air-launch rockets to be used with the Stratolaunch aircraft, which, when completed, will have the largest wingspan of any plane ever built.

With the Pegasus XL rockets, the Stratolaunch aircraft will be able to launch small satellites weighing up to 1,000 pounds, according to the firms’ joint statement released Thursday. Pegasus rockets already have done this kind of work: Orbital ATK has used them to launch satellites from the belly of its Stargazer aircraft.

This deal suggests to me that Vulcan Aerospace has a problem. It couldn’t find anyone to build a large rocket for Stratolaunch and this deal was therefore conjured up to paper over this problem. First , it appears that the reason Orbital ATK originally backed out was that they didn’t want to build the new rocket. Maybe they had engineering concerns. Maybe they were worried about cost or management. Regardless, they didn’t want to build it.

Second, using Stratolaunch with Pegasus seems pointless if the satellite weigh is still limited to only 1,000 pounds. That’s the payload capacity of Pegasus using Orbital ATK’s L-1011 Stargazer airplane. Why bother switching to Stratolaunch if the giant plane doesn’t give you any benefits?

Thus, it appears to me that what has happened is that Vulcan needed some rocket to use with Stratolaunch so that they could squelch the rising doubts about the company. This deal gives them that. It also probably gives Orbital ATK some extra cash to get them to agree to do it.

Redesigned Antares launch scheduled for Oct 13

NASA and Orbital ATK have now set October 13 as the date for the first Antares launch in two years.

Though ISS is not short of supplies, this quote underlines the difficulty of the particular situation now.

While the space station has plenty of food, water, experiments and other provisions, NASA officials are eager for the Antares rocket to resume flights as all of the research outpost’s other servicing vehicles are facing delays.

SpaceX’s Falcon 9 rocket, which launches the company’s Dragon cargo craft, is grounded after a launch pad explosion Sept. 1, and Dragon resupply missions to the space station may not start up again until early next year.

The Japanese HTV cargo freighter was supposed to blast off Sept. 30 with several tons of supplies, including new lithium-ion batteries for the space station’s electrical system. But that launch has been delayed until at least December after Japanese engineers discovered a leak during an air tightness test in August.

And a Soyuz crew capsule that was supposed to launch Sept. 23 with three new space station residents will not lift off until at least Oct. 19 after Russian workers discovered a technical problem on the vehicle. The Soyuz delay will likely push back the launch of Russia’s next unpiloted Progress cargo freighter from Oct. 20 until late November or early December.

Even with numerous redundent methods for hauling cargo to ISS, it is still possible for them all to have problems all at once.

Orbital ATK aims for October 9-13 Antares launch

Orbital ATK and NASA have now scheduled the first Antares/Cygnus launch since the rocket’s failure in October 2014 for no earlier than October 9.

Orbital ATK is targeting Oct. 9-13 for the launch of the company’s upgraded Antares 230 rocket. Liftoff will occur from the Mid-Atlantic Regional Spaceport to send the OA-5 Cygnus spacecraft, called S.S. Alan G. Poindexter, to the International Space Station (ISS). According to a news release from the company, a more specific date and time will be selected upon completion of final operational milestones and technical reviews. Launch times on these dates range from 10:47 p.m. EDT Oct. 9 to 9:30 p.m. EDT Oct. 13 (2:47 GMT Oct. 10 to 1:30 GMT Oct. 14).

Antares return now set for October

The competition heats up: The first flight of Orbital ATK’S redesigned Antares rocket since the 2014 launch failure is now expected to occur in October.

Originally planned for August, the launch had been delayed partly because of technical issues uncovered during a May static fire test and partly because of scheduling complications with other launches to ISS.

Orbital ATK delays Antares-Cygnus launch until September

In the heat of competition: Orbital ATK has once again pushed back the launch of the first upgraded Antares rocket since its launch failure in October 2014, this time until September.

Due to a variety of interrelated factors, including the company’s continuing processing, inspection and testing of the flight vehicle at Wallops Island, and NASA’s scheduling of crew activities on the International Space Station in preparation for upcoming cargo and crew launches, Orbital ATK is currently working with NASA to target a window in the second half of September for the launch of the OA-5 mission. A more specific launch date will be identified in the coming weeks.

This press release suggests that all is well, and that the delay is mostly because of scheduling issues with NASA and ISS. However, it is also very vague, which suggests to me that the company has been also working through the results of the static fire test they did in May and might have needed more time to work out the kinks..

Iridium’s next generation constellation of satellites

The competition heats up: Iridium prepares the first 10 of a total of 81 new satellites for launch on SpaceX’s Falcon 9 in September.

The Iridium Next program is a $3 billion investment by Iridium, according to Matt Desch, Iridium’s chief executive officer. Iridium’s purchase of 81 satellites represents approximately $2.2 billion of that cost, Desch said, and the company’s launch contract with SpaceX for seven Falcon 9 flights was valued at $492 million when the parties signed it in 2010. That was the largest commercial launch contract in history until last year’s 21-launch order by satellite Internet provider OneWeb with Arianespace.

The first 10 Iridium Next satellites will fly on a Falcon 9 rocket in September, followed by a second launch as soon as December with the next batch. Iridium managers will give the go-ahead for the second launch once the first 10 satellites finish initial in-orbit tests, Desch said. The other five launches should occur about once every two months next year to fill out the Iridium Next fleet 485 miles (780 kilometers) above Earth. Iridium’s contract with SpaceX calls for all the missions to fly on newly-built Falcon 9s, a situation unlikely to change any time soon since insurance arrangements for the initial launches have been finalized.

But Desch said he is open to purchasing reused Falcon 9 boosters in the future “if they’re the right price.”

To meet this schedule SpaceX’s launch schedule will have to ramp up considerably from its present rate of one launch about every three weeks.

Video of fire experiment on Cygnus

NASA scientists have released videos of the fire experiment they ran on Orbital ATK’s Cygnus freighter last week after it was unberthed from ISS.

The videos are at the link. They are not as exciting or as interesting as I think everyone imagined. However, they do confirm that the sample burned for 8 minutes.

ULA pinpoints cause of Atlas 5 premature shutdown

In the heat of competition: ULA has completed its investigation into the premature shutdown of the Atlas 5 first stage during its March launch of Orbital ATK’s Cygnus capsule and has corrected the problem.

An extensive review of all post-flight data observations determined that at approximately T+222 seconds, an unexpected shift in fuel pressure differential across the RD-180 Mixture Ratio Control Valve (MRCV) and a reduction in fuel flow to the combustion chamber caused an oxidizer-rich mixture of propellants and a reduction in first stage performance. The imbalanced propellant consumption rate resulted in depletion of the first stage oxidizer with significant fuel remaining at booster engine shutdown. The engine supplier has implemented a minor change to the MRCV assembly to ensure the anomaly does not occur on future flights.

Engine hot-fire testing, extensive component and assembly level testing and analyses have been performed to confirm the findings. Detailed inspections and minor hardware replacement on all engines will support the current launch manifest.

They have now scheduled the next Atlas 5 launch for June 24.

Orbital ATK delays Antares launch until August

In the heat of competition: The review of Orbital ATK’s May 31st static fire test of its Antares rocket has caused the company to delay the upgraded rocket’s first launch until August.

Additional information pointed to data on “vibrations” during the Static Fire test that could be deemed as a problem for the vehicle’s avionics. A “fix” was already understood to have been approved.

Orbital ATK, while admitting the launch is slipping from its early July launch date estimate to a date likely to be in the August timeframe, pointed to trajectory evaluations as a specific relation to the launch date deliberations. “Final trajectory shaping work is also currently underway, which is likely to result in an updated launch schedule in the August timeframe,” added Orbital ATK.

They expect to make a decision on launch date in a few weeks.

Cygnus to depart ISS, then start a fire

A fire in space: Orbital ATK’s Cygnus capsule is scheduled to leave ISS on Tuesday, when shortly thereafter it will begin a controlled fire experiment.

“Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions. – See more at: http://www.space.com/17933-nasa-television-webcasts-live-space-tv.html#sthash.2DjFjJqY.dpuf

The departure is scheduled for 9 am (eastern), and will aired live by NASA.

Orbital ATK successfully completes Antares test fire

The competition heats up: Orbital ATK today successfully completed a 30 second test fire of the first stage of its redesigned Antares rocket, using new Russian rocket engines.

The primary goal of the test was to verify the functionality of the integrated first stage, including new engines, modified Stage 1 core, avionics, thrust vector control and pad fueling systems in an operational environment. During the test, a number of operational milestones were met including full propellant loading sequence, launch countdown and engine ignition and shut down commands, as well as multiple throttle settings including full engine power. The test also validated the launch pad’s operation, including propellant tanking and the use of the water deluge system to protect the pad from damage and for noise suppression.

Orbital ATK will now purge and clean the engines of residual propellants and return the first stage used in this test to the Horizontal Integration Facility for full reconditioning prior to its use on the OA-7 mission slated for later this year. The Orbital ATK team will continue to prepare the Antares rocket that will launch the OA-5 mission, which is in the final stages of integration, systems testing and check-out in preparation for launch this summer.

They hope to launch a Cygnus capsule on Antares around July 6.

Antares static engine test scheduled

The 30-second static fire engine test of the Antares first stage and new Russian engine has now been scheduled for May 31.

The window for the engine test, or hot fire, is 5 p.m. to 8:15 p.m. EDT. Backup test dates run through June 5. Completion of the test will be noted on the Wallops’ Facebook and Twitter sites. During the test, the upgraded Antares dual RD-181 rocket engines will fire for 30 seconds at maximum 100% power (thrust) while the first stage of the test rocket will be held down on the pad. The hot fire will demonstrate the readiness of the rocket’s first stage and the launch pad fueling systems to support upcoming flights.

If all goes well, they hope to launch Antares with a Cygnus capsule in early July.

Orbital ATK introduces a new rocket

The competition heats up: Orbital ATK today revealed plans to build what it calls the Next Generation Launcher designed to compete with SpaceX’s Falcon 9.

The first stage would use a variation of the solid rocket boosters that ATK built for the space shuttle. The second stage would be bought from Blue Origin.

Upgraded Antares rolled to launchpad

The competition heats up: Orbital ATK’s upgraded Antares rocket, with new Russian engines for its first stage, has been rolled to the launchpad in preparation for its launch in July.

They plan to do a 30 second long hot fire engine test on the launchpad of the first stage engine to see if all works properly. If successful, they will then confirm the launch date in July.

Congress micro-manages rocket engineering again

In an effort to funnel money to Aerojet Rocketdyne at the cost of every other rocket company in the nation, the House Armed Services Committee has written a bill that tells the Air Force exactly how it will build its future rockets.

“The Committee shares the concern of many members that reliance on Russian-designed rocket engines is no longer acceptable,” the committee said April 25. “The Chairman’s Proposal, as recommended by Chairman Rogers of the Subcommittee on Strategic Forces, denies the Air Force’s request to pursue the development, at taxpayer expense, of new commercial launch systems. It instead focuses on the development of a new American engine to replace the Russian RD-180 by 2019 to protect assured access to space and to end reliance on Russian engines. The Mark also holds the Air Force accountable for its awards of rocket propulsion contracts that violated the FY15 and FY16 NDAAs.”

…“The funds would not be authorized to be obligated or expended to develop or procure a launch vehicle, an upper stage, a strap-on motor, or related infrastructure,” says a draft of the 2017 defense authorization bill.

As presently written, the bill would leave the Air Force only one option: use engines built by Aerojet Rocketdyne.

If anything demonstrates the corruption or foolishness of our elected officials, it is this proposal. Not only are they telling the Air Force how to design rockets, they are limiting the options so much that they are guaranteeing that it will either cost us more than we can afford, or it won’t be doable at all. As I say, either they are corrupt (working to benefit Aerojet Rocketdyne in exchange for money), or they are foolish, (preventing the Air Force from exploring as many inexpensive future options as possible).

Problems at Stratolaunch?

In the heat of competition: Vulcan Aerospace, the company building the giant Stratolaunch airplane designed launch orbital rockets from its underbelly, does not yet have a rocket for this purpose.

Originally that rocket was to be built by SpaceX, but that partnership ended in 2012.

Stratolaunch then contracted out its rocket work to Orbital Sciences Corp. (now Orbital ATK). The company also contracted with Aerojet Rocketdyne for six RL10C-1 rocket engines with an option for six more for use in the launch vehicle’s third stage.

The agreement with Orbital ended without the production of a launch vehicle, with Beames saying the rocket was not economical. Stratolaunch officials said they were reassessing the project in light of the shift in the market recently toward smaller satellites.

In 2015, Beames said that Stratolaunch was examining more than 70 launch vehicles for use with the Stratolaunch aircraft. He indicated that the company might use multiple launch vehicles to serve different payload classes. Beames said the company would announce its launch vehicle strategy in fall 2015, but that time came and went with no announcement. [emphasis mine]

It is very worrisome for them to be hunting for a rocket at this point of design. I am reminded of Virgin Galactic and SpaceShipTwo, which changed engine designs midstream, causing them enormous engineering problems and delays.

Orbital ATK negotiating lease for part of VAB

The competition heats up: Orbital ATK has begun negotiations with NASA for possibly leasing part of the Vehicle Assembly Building (VAB) for use in connection with a military rocket.

Virginia-based Orbital ATK is one of two rocket companies that launch resupply missions to the International Space Station, but this deal would not involve those missions or that rocket, the company’s Antares. The Antares launches from NASA’s space port at Wallops Island, Va., carrying the Orbital ATK Cygnus capsule.

The new rocket that Orbital ATK hopes to develop and one day assemble in the VAB would be a medium- to heavy-lift rocket.The planned rocket currently referred to by the name the Air Force set for it, the Evolved Expendable Launch Vehicle-class rocket.

It sounds like Orbital ATK is putting together a bid to compete for the Air Force rocket contract, and needs to get a handle on the costs for using the VAB at Kennedy in order to make the offer credible.
