Orbital Sciences is suing the government agency that operates the Wallops Island spaceport, saying it is refusing to pay a $16.5 million bill.

I am not surprised. One of the prime reasons the launch of Antares and Cygnus was delayed by more than a year was because this same government agency had failed to upgrade the launchpad as promised, and Orbital Sciences was eventually forced to step in, take over, and spend millions to do the work itself.

Because of the scheduled arrival of a Soyuz manned capsule to ISS on Wednesday, NASA and Orbital Sciences have decided to delay Cygnus’s rendezvous and berthing until Saturday.

Because of the scheduled arrival of a Soyuz manned capsule to ISS on Wednesday, NASA and Orbital Sciences have decided to delay Cygnus’s rendezvous and berthing until Saturday.

As far as I can tell, the software glitch and the delay are relatively minor issues, being handled with due care and caution, and will not prevent the eventual docking. More important, they are not serious enough to require any major design changes to Cygnus, which means the freighter will be able to begin operational flights soon after this demo flight is completed.

NASA has put Orbital Sciences on notice that, assuming its demo cargo mission to ISS in two weeks is a success, the company might have to do it again as soon as December.

The competition heats up: NASA has put Orbital Sciences on notice that, assuming its demo cargo mission to ISS in two weeks is a success, the company might have to do it again as soon as December.

SpaceX is supposed to fly its next cargo mission first, but NASA thinks that flight will be delayed because of development issues with the upgraded Falcon 9 rocket.

Orbital Sciences prepares its Cygnus capsule for its first flight to ISS, set for launch on September 17.

The competition heats up: Orbital Sciences prepares its Cygnus capsule for its first flight to ISS, set for launch on September 17.

Orbital officials said the Cygnus spacecraft was scheduled to be attached to the upper stage of the Antares launcher Wednesday. Final cargo loading into the Cygnus spacecraft’s pressurized module is set for Saturday, followed by its enclosure inside the rocket’s 12.8-foot-diameter payload fairing.

Rollout of the Antares rocket from its horizontal integration facility to the launch pad one mile away is expected Sept. 13.

September will be a busy and important month for private space. We also will have SpaceX’s first commercial launch with its Falcon 9 rocket. If both are successful, the trend away from a big government space programs shall accelerate.

Assuming the first demo berthing of Orbital Sciences’ Cygnus capsule to ISS goes well in September, NASA has now scheduled the subsequent cargo missions of Cygnus and Dragon for December and January respectively.

Assuming the first demo berthing of Orbital Sciences’ Cygnus capsule to ISS goes well in September, NASA has now scheduled the subsequent cargo missions of Cygnus and Dragon for December and January respectively.

The second link above also provides some interesting details about the cargo that Dragon will carry in January.

ATK has joined Stratolaunch, winning a contract to provide solid rocket motors for company’s proposed second stage air-launched rocket.

The competition heats up: ATK has joined Stratolaunch, winning a contract to provide solid rocket motors for company’s proposed second stage air-launched rocket.

Stratolaunch’s first stage will take off from a runway, and will be the largest airplane ever built. The second stage, which Orbital Sciences is building and which ATK is now be a partner, will be released from this airplane and then ignite.

Orbital Sciences has issued an update on its Antares launch schedule, with the launch window now set for September 14-19.

The competition heats up: Orbital Sciences has issued an update on its Antares launch schedule, with the launch window for the Cygnus demonstration mission to ISS now set for September 14-19.

They announced this on July 10, but I am only now catching up. The launch could happen sooner, if there are delays to the launch of NASA’s LADEE moon probe. Right now the two launches are coordinated to have LADEE launch first.

Orbital Sciences is scrambling to find a reliable long term first stage engine for its Antares rocket.

Orbital Sciences is scrambling to find a reliable long term first stage engine for its Antares rocket.

The NK-33 engine that powered Antares’ first flight was built decades ago by Russia’s Kuznetsov Design Bureau and is no longer in production. Further, Orbital is uncertain about the quality of Aerojet’s remaining stockpile of 23 NK-33s, beyond those set aside for NASA’s CRS-1. Aerojet Rocketdyne is Orbital’s primary subcontractor and overhauls the old NK-33 engines into a configuration for Antares, dubbed AJ-26. Orbital officials say its only current alternative is the RD-180 engine made in Russia by NPO Energomash. But the United Launch Alliance (ULA), which operates the U.S. Air Force’s Atlas V and Delta IV fleets, holds exclusive rights in the U.S. to buy the RD-180.

Over the last four years, Orbital has inquired about purchasing the RD-180 from ULA, RD Amross and Energomash. “We could never get to first base on that,” says Michael Hamel, the company’s senior vice president of corporate strategy and development. Requests for support from the Air Force, Office of the Secretary of Defense and Congress were also met with silence, company officials say.

What I find disturbing about this story is the complete lack of effort by Orbital, Aerojet, or ULA to build their own engines. Even if new NK-33 engines are made by Aerojet, they will be manufactured in Russia, as are ULA’s engines. Why can’t they do what SpaceX has done and make their own engines?

Stratolaunch officially announced today that Orbital Sciences will build the system’s second stage rocket.

The competition heats up: Stratolaunch officially announced today that Orbital Sciences will build the system’s second stage rocket.

The rocket that Orbital will build for Stratolaunch will launch from the air, the first stage being a giant airplane which will carry that rocket aloft, much like Virgin Galactic’s WhiteKnightTwo and Orbital’s Pegasus rocket. Clark Lindsey at the same website also notes that the efforts of SpaceX (and to my mind Stratolaunch) to make the first stage reusable will likely revolutionize the rocket industry.

A rocket reveals a fundamental truth about America

12:29 pm

Yesterday, Orbital Sciences successfully completed the first test launch of its Antares rocket, developed, designed, and built in less than five years under a commercial contract with NASA to provide cargo to the International Space Station. The launch went like clockwork, perfectly, with no hitches at all, something that is quite remarkable for a new rocket on its first launch. Kudos to the engineers at Orbital Sciences for a job well done!

Besides demonstrating the skill of Orbital Science’s engineers, however, this successful launch illustrated in stark reality a fundamental fact about the culture of the United States that continues to allow it to stand out from the rest of the world, even as a large percentage of the present generation of Americans are doing their darndest to try to destroy that culture. Moreover, that fundamental cultural fact is basic to human nature, not just the United States, and if we recognize it, it will provide us all the right framework for what to do and not to do in trying to maintain human societies, both here on Earth as well as in the future in space.

In order to understand the true significance of Orbital Sciences’s success yesterday with Antares, however, we must first review the capabilities of the world’s launch industry. I am not going to list all the rockets capable of putting payloads into orbit, only those that are successfully competing for business in the open commercial market.
