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.

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.

Overall, this delay is not a big deal. They want to swap out an engine to check a seal, plus they then have to coordinate the flight date with other missions to ISS.

The competition heats up: The Antares hot fire test of the rocket’s first stage was successfully completed tonight.
The 29-second hot fire test took place at 6:00 p.m. (EST) on February 22, 2013 at the Mid-Atlantic Regional Spaceport’s (MARS) Pad 0A, which was designed and built over the last several years to accommodate liquid-fuel space launch vehicles. The primary goals of the test were to ensure that the launch complex’s fueling systems and the Antares stage one test article functioned properly in a fully operational environment, that engine ignition and shut down commands operated as designed, and that the dual AJ26 first stage engines and their control systems performed to specifications in the twin-engine configuration. The test included a full propellant loading sequence, launch countdown and engine ignition operation. The pad’s high-volume water deluge system flowed throughout the entire period of the test to protect the pad from damage and for noise suppression.
The first stage will now be prepped for a full scale test launch of Antares, expected in about six weeks. If that is successful, Orbital Sciences will then follow with a flight of the Cygnus capsule to ISS.

This is good, but the questions about the Antares’ system for ejecting its shroud after launch still remain, threatening the rest of the schedule.

NASA used Orbital Sciences’ Taurus 2 rocket for the failed launch of its Glory climate satellite in 2011, even though the agency knew the company had not fixed the problem that caused the loss of the Orbiting Carbon Observatory in 2009.
NASA used Orbital Sciences’ Taurus XL rocket for the failed launch of its Glory climate satellite in 2011, even though the agency knew the company had not fixed the problem that caused the loss of the Orbiting Carbon Observatory in 2009.
The investigators believed there was as much as a 50% chance the faulty component — a fairing separation system for ejecting the protective shroud that covered the satellite during launch — would fail again. Sadly, it did, destroying Glory. More significant for the future, however is this:
Other Orbital vehicles, including the air-launched Pegasus and a new Antares rocket, use a version of the same fairing separation system that is most likely responsible for the combined $700 million loss of two key climate-study satellites. Orbital’s original name for Antares was Taurus II.
So far, NASA has not accepted the Antares shroud-separation configuration for operational flights. Dulles, Va.-based Orbital says it has made a number of changes to its frangible joint fairing separation system in the wake of the Glory launch failure, including modifications to the frangible rail used on Antares. The company is developing that rocket under NASA’s Commercial Orbital Transportation Services (COTS) program to carry cargo to the International Space Station (ISS).
If NASA isn’t satisfied with Orbital’s design changes to this system, it could significantly delay the launch of Cygnus and Antares to ISS.
Update: I had mistakenly referred to the Taurus 2 in the first sentence when the rocket used to launch Glory and OCO was the Taurus XL. This is now corrected.

They don’t explain the reason for the Cygnus delay. I suspect they simply decided to be realistic. It was always unlikely that the first Cygnus launch would follow only a month after the first Antares launch, especially if there are any kinks in that launch.

The irony of this press release story is that Orbital has actually been running things, as it took over prepping the launchpad last year when the spaceport was unable to handle it.
