Orbital Sciences has announced a further delay to July 1 for the next Antares/Cygnus cargo mission to ISS in order to complete its investigation into the failure of a Russian engine during testing.

The total delay is now about a month. The press release provides no information as to the status of the investigation, so why it is taking longer than originally expected is unexplained.

Orbital Sciences has delayed its next Cygnus flight to ISS by at least one week in order to complete its investigation of the failure of a Russian-built rocket engine used by the Antares rocket.

Orbital Sciences has delayed its next Cygnus flight to ISS by at least one week in order to complete its investigation of the failure of a Russian-built rocket engine used by the Antares rocket.

Without doubt, this engine failure highlights the urgent need for American rocket companies to develop their own rocket engines.

NASA is preparing the next round of commercial contracts to supply cargo to ISS.

1:34 pm

The competition heats up: NASA is preparing the next round of commercial contracts to supply cargo to ISS.

NASA announced the plan in a request for information released late Feb. 21. Responses from industry are due March 21. The document, which NASA posted online, did not say when the agency would solicit bids, or when it would make an award for the Commercial Resupply Services 2 (CRS) contract. The expected budget for CRS 2 is between $1 billion and $1.4 billion a year from 2017 to 2024, NASA said. NASA envisions four to five flights a year under CRS 2. Back in January, the White House announced it wanted to extend space station operations through 2024. Congress has currently committed to fund the space station through 2020. CRS 2 contract calls for delivery of 14,250 to 16,750 kilograms per year of pressurized cargo, and delivery of 1,500 to 4,000 kilograms per year of unpressurized cargo.

Assuming both SpaceX and Orbital Sciences win new contracts, this will give them a strong cash flow as they pursue new space endeavors.

Orbital Sciences’ balance sheets booming as a result of commercial space.

Orbital Sciences’ balance sheets booming as a result of commercial space.

“Orbital’s fourth quarter financial results reflected solid growth in revenues, earnings per share and free cash flow, and capped a very successful year in 2013,” noted Mr. David W. Thompson, Orbital’s Chairman and Chief Executive Officer. This highly successful report reflects the successes Orbital have enjoyed during the last year. The most publicly recognized successes have involved the opening launches of their new Antares launch vehicle, two of which lofted the first Cygnus spacecraft on their missions to the ISS.

Cygnus was successfully berthed to ISS today.

Cygnus was successfully berthed to ISS today.

This is the first operational station resupply mission carried out by Orbital Sciences under a $1.9 billion contract with NASA calling for at least eight flights and delivery of 40,000 pounds of cargo and supplies.

The Cygnus captured Sunday will remain attached to the space station until mid February. At that point SpaceX will step up with launch of a Dragon cargo ship around Feb. 22. It will be the third operational resupply flight by SpaceX, which holds a $1.6 billion contract to deliver more than 44,000 pounds of supplies over a dozen missions.

Orbital Sciences has successfully launched its Cygnus cargo ferry into orbit.

Orbital Sciences has successfully launched its Cygnus cargo ferry into orbit.

Another perfect launch for the company.

Consider once again what has happened. While it cost NASA six years and $9 billion to build nothing before its Constellation program was cancelled, two private companies have built and launched two different rockets and unmanned cargo spacecraft in that same time period for about a third of that cost.

The contrast couldn’t be more stark. And that contrast will get even more stark as the flights of the privately built manned spacecraft by SpaceX, Boeing, and Sierra Nevada unfold in the coming three years, while SLS and Orion sit around and do little but spend money.

Orbital Sciences has scrubbed today’s launch of Cygnus due to the major solar flare that occurred yesterday.

Orbital Sciences has scrubbed today’s launch of Cygnus due to the major solar flare that occurred yesterday.

“Early this morning the Antares launch team decided to scrub today’s launch attempt due to an unusually high level of space radiation that exceeded by a considerable margin the constraints imposed on the mission to ensure the rocket’s electronic systems are not impacted by a harsh radiation environment,” Orbital Sciences officials said in a statement today.

NASA engineers have decided to go ahead with a series of spacewalks to repair the ISS cooling system, thereby delaying the Cygnus cargo mission until January.

NASA engineers have decided to go ahead with a series of spacewalks to repair the ISS cooling system, thereby delaying the Cygnus cargo mission until January.

The EVAs will take place on December 21, 23 and 25 followed by a Russian Spacewalk on the 27th and a Beta-Angle Cut-out beginning on December 29. That means that the earliest launch opportunity for Cygnus is January 9, 2014 (local time) – pending the successful execution of the contingency EVAs.

Update: The Orbital Sciences press announcement says their launch can happen no earlier than January 13.

The coolant systems failure on ISS might delay next week’s Cygnus cargo mission.

5:50 pm

The coolant systems failure on ISS might delay next week’s Cygnus cargo mission.

[T]he reduced cooling capability means there’s less of a safety margin on the station. Todd said mission managers don’t want to risk having the Cygnus come in for a hookup under such conditions. “While we’re sitting at one loop, we’re somewhat vulnerable,” he said.

The logic here escapes me. It suggests they will stop all cargo missions to ISS until the coolant problem is solved. However, what if they can’t solve it without a spacewalk? To do that spacewalk they have to deliver an upgraded spacesuit to the station to replace the suit that had water leak problems in July, and that delivery is not scheduled until late February when the next Dragon cargo launch is scheduled.

Maybe they are considering putting that replacement suit on the Cygnus capsule so it can arrive quickly. If so, that would justify delaying the Cygnus launch for a few days.

More details about the situation here.

Cygnus will be de-orbited one day early, on October 23.

Cygnus will be de-orbited one day early, on October 23.

At the same time, preparations move forward for the second Cygnus flight in December, which will be the first operational flight. This quote is interesting:

Neither Orbital nor the Virginia Commercial Space Flight Authority got locked out of the Mid-Atlantic Regional Spaceport as a result of the shutdown, meaning that preparations for the tentative December launch continued while more than 95 percent of NASA’s roughly 18,000 civil servants were on furlough.

Suggests again how unessential a good percentage of NASA’s employees really are. They might be great engineers, but they are apparently wasting their talents at NASA doing unnecessary make-work.

Except for a troublesome fan, the first Cygnus cargo capsule to dock with ISS is performing perfectly.

Except for a troublesome fan, the first Cygnus cargo capsule to dock with ISS is performing perfectly.

The fan has been a minor issue. The astronauts have simply turned it off periodically when it started to act up. What is really important is this:

The next Cygnus – along with its Antares launch vehicle – is already being processed at Orbital’s Wallops facility, with a target launch date of December 15, with an available launch window through to December 21.

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

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.
