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.

More delays seen in the completion of a new and critical module to the Russian portion of ISS.

More delays seen in the completion of a new and critical module to the Russian portion of ISS.

The delays have nothing to do with the Ukraine and everything to do with poor quality control in the Russian company building the module.

This quote stood out however:

With its central position in the architecture of the Russian segment, the MLM’s troubles also stall the launch of all subsequent Russian components of the station, including the Node Module, UM, (already under construction) and the NEM laboratory and power supply module, whose full-scale development started in 2012.

Given such a prolonged delay, combined with worsening political relations between Russia and its partners in the ISS project, the questions were raised whether the MLM module and the successive components of the Russian segment could be grounded until the assembly of the new all-Russian station in the post-ISS era. Under such a scenario, the troubled spacecraft could play a role of an early hub for the future orbital outpost.

If the Russians get enough modules built to launch their own station, I expect them to do it and cut their ties with ISS.

SpaceX has released video of its Falcon 9 first stage splashing down vertically in the ocean.

SpaceX has released video of its Falcon 9 first stage splashing down vertically in the ocean.

The video is not very good, but at one point you can clearly see for a flash that the first stage is vertical and appears to be hovering above the water.

For decades engineers and managers in the aerospace industry have said that returning a first stage vertically made no sense. Elon Musk insisted that SpaceX try. It appears he and his company are now going to prove that everyone else was wrong about this.

Russia responds to new U.S. sanctions by threatening U.S. astronauts on ISS.

10:06 am

Uh-oh: Russia responds to new U.S. sanctions by threatening U.S. astronauts on ISS.

Moscow reacted with fury to the inclusion in the sanctions of high-tech exports to Russia and threatened reprisals. “If their aim is to deliver a blow to Russia’s rocket-building sector, then by default, they would be exposing their astronauts on the ISS,” Russian Deputy Prime Minister Dmitry Rogozin said, according to the Interfax news agency.

“Sanctions are always a boomerang which come back and painfully hit those who launched them,” added Rogozin on a visit to Crimea, which Russia annexed from Ukraine in March. [emphasis mine]

Was Rogozin actually hinting that Russia might strand U.S. astronauts on ISS?

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.

Arianespace today scrubbed the third launch of its new Vega rocket at T-minus 10 minutes due to a technical problem.

Arianespace today scrubbed the third launch of its new Vega rocket at T-minus 10 minutes due to a technical problem.

The reliability of Arianespace’s rockets has always been the company’s big selling point, so a launch scrub is very unusual for them. Then again, this is only the third launch of Vega, so we shouldn’t be surprised if they are still working out the kinks.

ULA has accelerated delivery of its required Russian rocket engines in anticipation of worsening relations with Russia and with members of Congress.

The competition heats up: ULA has accelerated delivery of its required Russian rocket engines in anticipation of worsening relations with Russia and with members of Congress.

ULA presently is the only company the Air Force uses to launch its military satellites, and members of Congress are questioning this monopoly in the context of the situation in the Ukraine as well as SpaceX’s lawsuit challenging it.

Russia has noticed literally no change in cooperation with NASA since the U.S. government announced two weeks ago that all such cooperation, excluding ISS, was being cut off.

Surprise, surprise! Russia has noticed literally no change in cooperation with NASA since the U.S. government announced two weeks ago that all such cooperation, excluding ISS, was being cut off.

Russia’s Roscosmos space agency has yet received no official notifications from NASA on curtailing cooperation, and working contacts continue, Roscosmos chief Oleg Ostapenko said in an interview with Vedomosti newspaper Wednesday. “Roscosmos has received no official notifications on suspending cooperation, we continue working contacts with NASA and other space agencies,” Ostapenko told Vedomosti adding: “Recently I held talks with the NASA leadership and European colleagues.”

I had said that so-called NASA cut-off was all show and aimed not at Russia but at Congressional budget negotiations over NASA’s commercial crew program. This story only proves it.

Arianespace struggles to schedule its customers for launch.

Arianespace struggles to schedule its customers for launch.

The editorial describes the juggling act the company is often forced to perform organizing the duel payloads required by the Ariane 5, with the launch of some customers’ satellites delayed because of the late arrival of other customers. From this information it is clear that the competition coming from SpaceX is not limited only to price. Arianespace’s requirement on Ariane 5 that there be two satellites means that sometimes they have to do harm to one of their customers by delaying their launch, even if that customer delivered on time. I can imagine some of those customers quite willing to go elsewhere should this happen too often.

Data now suggests that SpaceX successfully achieved a controlled landing of its Falcon 9 first stage on Friday.

The competition heats up: Data now suggests that SpaceX successfully achieved a controlled landing of its Falcon 9 first stage on Friday.

The stage itself has not yet been recovered due to heavy seas, but all evidence points to a soft splashdown in the ocean. While I expect them to continue to do this over the ocean, until they get good footage of the landing as well as recover the stage, the next real step is to land the thing over land. The link above also has video of the vertical take-off/landing of Falcon 9R on Friday, which proves they are beginning to prove this capability as well.

In related news, Dragon was successfully berthed to ISS today.

Some additional details about SpaceX’s effort Friday to bring the first stage of its Falcon 9 rocket back to Earth gently.

They have not yet released a full report, but it appears that the company has made progress. They were able to control the stage’s spinning as it descended, and it apparently was still functioning after it hit the water.

SpaceX has completed the first vertical flight of the Falcon 9R landing test rocket.

8:22 am

The competition heats up: SpaceX has successfully completed the first vertical flight of the Falcon 9R landing test rocket.

Reports have been confirmed that SpaceX’s Falcon 9-R development vehicle made its first free flight today at McGregor — taking off, hovering, moving sideways and landing.

Falcon 9R is the successor to Grasshopper, carrying more engines to more accurately simulate a Falcon 9 first stage.

Meanwhile, today’s launch of Dragon and the second attempt to bring the first stage back to Earth in a controlled manner remains iffy because of weather.

Russia is accelerating construction of its new spaceport in Vostochny.

The competition heats up: Russia is accelerating construction of its new spaceport in Vostochny.

The schedule doesn’t appear to have been pushed up, with the first launch still set for 2015, but they are going to initiate a second shift, and will have monthly meeting with the government to monitor progress. Under the top-down Russian way of doing things, this is how they make sure their high priority projects get finished on time and successfully.

Sierra Nevada is planning additional glide tests in the fall. using its Dream Chaser engineering test vehicle.

9:48 am

The competition heats up: Sierra Nevada is planning additional glide tests in the fall. using its Dream Chaser engineering test vehicle.

This is the same test vehicle that crashed last October during its first glide test when one landing gear failed to deploy properly. The glide test itself was a success however, as the vehicle did a controlled unmanned glide perfectly to the runway, and the failed landing gear was one that the spacecraft will not use once completed.

Note also that these announced flight tests will occur after NASA eliminates one of the companies competing for the final crew ferrying contract to ISS. This suggests that Sierra Nevada plans to continue development of Dream Chaser, regardless of whether they get the contract or not.
