Orbital plans upgrade to Antares

1:00 am

The competition heats up: On its next cargo mission to ISS Orbital Sciences plans on launching an upgraded Antares rocket.

For its third paid cargo mission to station, slated to launch Oct. 21, Orbital will replace the ATK Castor 30B Antares used for its latest launch with an ATK Castor 30XL. The upgrade will allow Cygnus to carry about 2,290 kilograms of cargo to station — an increase of nearly 40 percent by mass, compared with the second mission, according to Orbital’s Aug. 18 press release.

The Castor 30XL is the latest in the Castor 30 series ATK developed specifically as an Antares upper stage. A pair of Antares demonstration launches in 2013, which did not count toward fulfilling the company’s delivery-and-disposal contract with NASA, used the Castor 30A. ATK has lengthened subsequent versions of the motor, squeezing more power out of it by packing it full of more solid fuel.

Like SpaceX, Orbital Sciences is demonstrating the ability here to do operational missions simultaneously with developmental missions.

Cygnus launch

9:23 am

All is go for a 12:52 pm launch of Cygnus’s second operational cargo flight to ISS.

If you live on the east coast of the U.S. you should be able to see some part of this launch when it happens.

Cygnus has lifted off.

The main engine has cut off and the first stage has successfully separated.

The second stage has ignited successfully. It has now completed its burn and has separated from the spacecraft. Cygnus is in orbit.

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.

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.

Orbital Sciences is considering using ATK’s solid rocket motors to replace the refurbished Russian engines in the first stage of its Antares rocket.

Orbital Sciences is considering using ATK’s solid rocket motors to replace the refurbished Russian engines in the first stage of its Antares rocket.

This helps explain the merger between the two companies, as it gives Orbital control over the equipment it needs to keep Antares viable. More important, it also could make it entirely American made, which will be attractive to both Congress and many U.S. commercial satellite companies.

ATK is splitting off its aerospace division to merge that division with Orbital Sciences.

9:27 am

The competition cools? ATK is splitting off its aerospace division to merge that division with Orbital Sciences.

Alliant Techsystems Inc. ATK on Tuesday said it plans to split into two independent companies, one focused on outdoor sports and hunting products, the other centered on aerospace and defense. The outdoor sports operations–which produce commercial ammunition, hunting products and other related items–will be spun off to Alliant shareholders in a tax-free transaction, the company said. The segment generated $2.2 billion in revenue during 2013, Alliant said.

After the separation, Alliant said it plans to merge the aerospace and defense business–which produces rocket propulsion systems and satellite systems, among other things–with rocket and space-system developer Orbital Sciences Inc. The company will be named Orbital ATK Inc.

More here. The company press releases call this “a merger of equals” and do not make it clear what instigated the deal. Did Orbital offer to buy ATK’s aerospace division with its ammo business spun off, or did ATK want to sell off its aerospace division to focus on ammo? I wonder. The ammo business right now is booming, while aerospace remains a much more risky venture. ATK might have wanted to focus on ammo, where the money is, and proposed the idea to Orbital.

NASA is looking to extend its commercial cargo contracts with SpaceX and Orbital Sciences until 2017.

8:44 am

NASA has extended its commercial cargo contracts with SpaceX and Orbital Sciences until 2017.

Since the notice says that “the modifications would be made ‘at no cost’ to the agency, and that they would be “executed one year at a time,” the extension is probably just designed to give the two companies sufficient time to launch all their cargo missions in the present contracts.

Nonetheless, the posting also said that other companies could compete for NASA’s business during this extension, which leaves the door open for more competition.

Orbital Sciences has begun construction of the 81satellites that will make up Iridium’s second generation communications satellite constellation.

The competition heats up: Orbital Sciences has begun construction of the 81satellites that will make up Iridium’s second generation communications satellite constellation.

Not only is this big business for satellite construction — 81 satellites is a big order — someone will have to launch those satellites. Even if they are launched in groups of five, which was how it was done for the first generation, it will still take more than 16 launches to get them all in orbit. That will be a lot of business for some lucky rocket company.
