Designing a propulsion system for cubesats

The competition heats up: Just like the Chinese tests of a smallsat propulsion system noted in my previous post, this U.S. company is designing a propulsion system for cubesats.

McDevitt’s propulsion system is deceptively simple. It combines rocket-fuel-grade hydrogen peroxide with a patented proprietary catalyst to create a chemical reaction that results in thrust channeled through tiny square nozzles incorporated into the small satellite. The system allows the satellites to be steered or stopped. The only byproduct of McDevitt’s tiny rocket motors is water vapor.

Except for this quote the article doesn’t provide much information about the design, probably because the builders didn’t reveal the details for proprietary reasons. They hope to launch a test satellite by 2018.

Russia and ESA in money dispute

A money dispute between Russia and France could threaten the ESA/Russian ExoMars partnership, as well as the Arianespace deal that launches Soyuz rockets from French Guiana.

In what appears to be an attempt to force France’s European neighbors to apply pressure to Paris, Roscosmos hinted that multiple cooperative space efforts between Russian and the European Union, and with the European Space Agency (ESA), could suffer if the payments are not freed. The payments, which are not disputed by Arianespace, have been one of the collateral effects of the battle by former shareholders of Russia’s Yukos oil company. In 2014, these shareholders won an initial award of $50 billion from an international arbitration panel in The Hague, Netherlands, against the Russian government for dismantling the company.

Since then, the shareholders have been trying to collect Russian government assets wherever they find a sympathetic legal environment outside Russia, including France and Belgium. In France, different shareholder representatives sought seizure of the Eutelsat and Arianespace payments. The same dispute has blocked payments to other Russian companies. Paris-based satellite operator Eutelsat owes Russia’s biggest satellite operator, Russian Satellite Communications Co. (RSCC) of Moscow, around $300 million for services related to Eutelsat use of RSCC satellites.

Russia needs cash, which is why they need their partnership with Arianespace, which has brought them a lot of cash over time. Their problem is that the money owed the Yukos oil company shareholders has allowed those shareholders to put liens on any Russian earnings in Europe, which has only increased Russia’s financial bind. If Russia can’t get its hands on its Arianespace earnings, then it really makes no sense for them to continue the partnership. Better to threaten to pull out with the hope that the threat will maybe force payment.

Moreover, Russia might also be realizing that it cannot at present afford to participate in ExoMars and is looking for a way to get out of that commitment. This money dispute gives them that out.

Russia considers using Ukrainian rocket

For the first time since it annexed Crimea, Russia has opened negotiations with a Ukrainian company to possibly use its Zenit rocket to launch a Russian satellite.

RKK Energia of Korolev, Russia, entered negotiations with KB Yuzhnoe of Dnepropetrovsk, Ukraine, on a potential deal to launch a satellite for Angola on a Ukrainian-built Zenit rocket. Under the proposed plan, the Angosat-1 satellite would ride the last fully assembled Zenit rocket still remaining in Baikonur. The mission is seen by industry insiders as the first step in the resumption of Zenit missions, which if successful, will eventually shift from Baikonur to the Sea Launch ocean-going platform based in Long Beach, California.

The situation here is beyond complicated. Russia remains in many ways in a state of war with Ukraine. Yet, the Sea Launch platform, recently purchased by a Russian airline company, needs the Ukrainian Zenit rocket. It appears that this need is forcing the Russians to once again buy from the Ukraine. At the same time, Sea Launch remains parked in the U.S., and will likely not be available until Sea Launch and Russia settle the lawsuit Boeing has filed against the company. Meanwhile, the Zenit rocket in question however needs refurbishing and was originally built to launch a different satellite, which will have to agree to fly on a different launch vehicle.

Did fueling procedures cause Falcon 9 launchpad explosion?

This Wall Street Journal article today speculates that “problematic fueling procedures” might have caused the September 1 Falcon 9 launchpad explosion.

Company officials have said it is too early to arrive at definitive answers, though one person familiar with the investigation said initial concerns about potentially substandard welds have been relegated to a low priority. If testing bears out early findings focusing on problematic fueling practices instead of hardware flaws, SpaceX likely will avoid a major redesign effort or extensive quality-control checks that could drag on for months.

Caution must be exercised here. The article depends on unnamed sources, and does not provide any details describing how fueling procedures could have caused the explosion.

Celtic Woman – Isle of Inisfree

An evening pause: Written by Dirk Farrelly in 1950 while on a bus heading to Dublin, the song invokes the longing of an immigrant far from home.

And when the moonlight peeps across the rooftops,
Of this great city, wondrous though it be,
I scarcely feel its wonder or its laughter…
I’m once again back home in Inisfree.

Hat tip Edward Thelen.

Virgin Galactic lawsuit against Firefly moves forward

Virgin Galactic last week moved forward aggressively in its lawsuit against Firefly Space Systems, its officers, and its business partners for using stealing trade secrets.

According to the Complaint, Galactic hired Markusic in 2011 as its VP of Propulsion. Markusic’s role gave him intimate knowledge of the Company’s research into liquid rocket propulsion, space vehicle architecture, “aerospike” technology, and other confidential projects. While still employed at Galactic, Markusic allegedly solicited business partners and founded Firefly based on concepts and data he obtained in the course of his work. Galactic maintains that Markusic and Firefly relied on and continues to use the Company’s technical and marketing information, as well as Markusic’s engineering notes from his tenure at Galactic, to develop products such as a recently announced small launch vehicle.

The worst thing about this court battle to me is that if Virgin Galactic has developed worthwhile technology in connection with the aerospike engine, they have done nothing to develop it, and are now acting to squelch someone else’s effort.

Two Trump advisers push for National Space Council

In a somewhat vague op-ed today, two Trump space policy advisers, former Congressman Robert Walker and University of California-Irvine professor Peter Navarro, recommend the re-establishment of the National Space Council to coordinate the U.S.’s civilian space effort.

Despite its importance in our economic and security calculations, space policy is uncoordinated within the federal government. A Trump administration would end the lack of proper coordination by reinstituting a national space policy council headed by the vice president. The mission of this council would be to assure that each space sector is playing its proper role in advancing U.S. interests. Key goals would be to would create lower costs through greater efficiencies. As just one example, a Trump administration will insist that space products developed for one sector, but applicable to another, be fully shared.

Here, it makes little sense for numerous launch vehicles to be developed at taxpayer cost, all with essentially the same technology and payload capacity. Coordinated policy would end such duplication of effort and quickly determine where there are private sector solutions that do not necessarily require government investment. [emphasis mine]

This analysis of the op-ed at SpacePolicyOnline.com gives some history of the National Space Council, as well as range of opinions about its usefulness.

Opinions in the space policy community about the value of such a Council run the gamut. Opponents argue it is just one more White House entity that can say “no” to any idea, but without the clout to say “yes” and make something happen. Supporters insist that a top-level mechanism is needed not only to effectively coordinate government civil and national security space programs, but to bring in the commercial sector and develop a holistic approach to space.

Walker and Navarro clearly share the latter opinion. They say the Council would “end the lack of proper coordination” and “assure that each space sector is playing its proper role in advancing U.S. interests.”

I however want to focus on the highlighted text above from the op-ed. This language appears to suggest that these advisers do not think it efficient for NASA to buy rockets and spacecraft from competing private companies, as it is doing with its cargo and crew ferries to ISS. If so, their advice will mean that a Trump administration will eliminate the competition that has been so successful in the past decade in lowering NASA’S costs and getting so much more done.

Yet, in the very next paragraphs Walker and Navarro say this:
