Happy birthday Linux!
On this date in 1991 Linus Torvalds announced that he had developed a free computer operating system and wanted help from others to improve it. That operating system is what we today call Linux.

SpaceX delays commercial launch 24 hours
SpaceX has delayed its next commercial launch one day to Wednesday in order to make sure the issues that caused its Falcon 9R test rocket to self-destruct are irrelevant to the full Falcon 9 rocket.
Seems like a prudent decision that is also not overly timid. If this had been the NASA of the past few decades, they would have generally delayed the launch for far longer.
Europe’s continuing problems with Galileo GPS
A look at this week’s failed Soyuz launch and the continuing problems Europe has had building its Galileo GPS satellite constellation.
The program has had a series of problems and failures, which this most recent launch only helps highlight.
Soyuz puts two satellites in wrong orbit
A Russian-made Soyuz rocket launched from French Guiana for Arianespace has placed two European Galileo GPS satellites into the wrong orbit.
Russianspaceweb suggests that the problem was caused by the rocket’s Russian Fregat upper stage. (Scroll down about halfway to read their report on this launch.)
Multiple independent sources analyzing the situation suggested that the Fregat upper stage had fired its engine for the right duration, however the stage’s orientation in space during the second or both maneuvers had probably been wrong. According to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics and a veteran space historian, the Fregat’s angular orientation error during engine firing could reach as much as 145 degrees.
This failure is a triple whammy. It hits both Arianespace and Russia since the Soyuz was part of a partnership between the two. It also hits Europe’s Galileo GPS satellite, which after many years of development was beginning to move towards full operation.
Sea Launch has suspended all operations until 2015
Russian competition cools down: The mostly Russian-owned rocket company Sea Launch has suspended all operations until mid-2015.
I suspect that the Russian government, now in control of almost all Russian aerospace efforts, is not interested in building this company up as the rocket it uses is partly made in Ukraine and is a competitor to Russia’s new Angara rocket. Everything the Russian government has done for the past year has indicated a desire to shut down all cooperative efforts with other countries and focus everything towards all-Russian efforts.
Thus, Sea Launch dies.
Falcon 9R destroyed during failed test flight
In a test flight today of SpaceX’s Falcon 9R vertical take off and landing rocket the rocket was destroyed when ground controllers detected an “anomaly.”
Falcon 9R is a three engine version of the Falcon 9 first stage, designed to test designs for making that first stage capable of landing vertically. It has flown successfully a number of previous times, but this time it appears something was not quite right during the flight and ground controllers had to destroy it for safety reasons.
Is this a set back? Of course. Is it a failure? Not really, as it was a test flight of very cutting edge technology and even failures will teach you something to improve the engineering.
Air Force requests info for new engine
Corporate welfare: The Air Force on Thursday issued a request for information from industry for the replacement of the Russian-made engines used by ULA’s Atlas 5 rocket.
Companies are being asked to respond by Sept. 19 to 35 questions. Among them: “What solution would you recommend to replace the capability currently provided by the RD-180 engine?” Air Force officials have told Congress they only have a broad idea of how to replace the RD-180. Estimates of the investment in money and time necessary to field an American-built alternative vary widely. Congress, meanwhile, is preparing bills that would fund a full-scale engine development program starting next year; the White House is advocating a more deliberate approach that begins with an examination of applicable technologies.
In the request for information, the Air Force says it is open to a variety of options including an RD-180 facsimile, a new design, and alternative configurations featuring multiple engines, and even a brand new rocket. The Air Force is also trying to decide on the best acquisition approach. Options include a traditional acquisition or a shared investment as part of a public-private partnership. [emphasis mine]
The Atlas 5 is built by Lockheed Martin. This is really their problem, not the Air Force or ULA. In addition, the Air Force has other options, both from Boeing’s Delta rocket family as well as SpaceX’s Falcon 9 rocket. For the government to fund this new engine is nothing more than corporate welfare, at a time when the federal government is swimming in debt and is essentially bankrupt.
Arianespace and ESA sign contract for three launches
Arianespace and the European Space Agency (ESA) signed a contract on Thursday for the Ariane 5 rocket to launch 12 more of Europe’s Galileo GPS satellites on three launches.
This contract is a perfect example of European pork. Europe’s Galileo system might provide competition to the U.S. GPS and Russian Glonass systems, but I am not sure what additional capabilities it provides that will convince GPS users to switch to it. Instead, building it provides European jobs, while using the Ariane 5 rocket to launch it gives that increasingly uncompetitive rocket some work to do. In fact, this situation really reminds me of the U.S. launch market in the 1990s, when Boeing and Lockheed Martin decided that, rather than compete with Russia and ESA for the launch market, they instead decided to rely entirely on U.S. government contracts, since those contracts didn’t really demand that they reduce their costs significantly to compete.
Europe now appears to be heading down that same road.
India delays next GSLV test launch
India has postponed its next GSLV test launch, originally scheduled for late in August.
The article gives no reasons for the delay. This is a new rocket with new engines, and this will only be its second test flight, so a delay is not unreasonable.
Sierra Nevada abandons its own hybrid engine for Dream Chaser
The competition heats up: Sierra Nevada has decided not to use its own hybrid engine on its Dream Chaser manned shuttle.
With the apparent decision by Virgin Galactic to also abandon this engine, it would appear that hybrid rocket technology is not yet ready for prime time, if ever.
Posted from Spokane, Washington, where Diane and I will be visiting my oldest friend Lloyd and his family for the rest of the week.
Orbital plans upgrade to Antares
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.
Competition with SpaceX forced ULA CEO out
A news story today in Defense News speculates that the competitive pressure from SpaceX is what forced ULA’s CEO to step down.
Changes at the CEO level are usually accompanied by a change in how business is done, said Byron Callan, an analyst with Capital Alpha Partners. “Generally, when you see abrupt leadership changes, there’s an abrupt change of strategic or tactical course needed,” Callan said. “You don’t make those changes unless you see something that needs fast corrective action.”
Caceres said he expects to see layoffs and a streamlining of ULA to find all possible cost savings. “My sense is you’re going to see at ULA a restructuring of some sort, because ultimately they’re going to have to find a way to be a lot more competitive on price,” he said.
This restructuring is entirely the result of the new competition from SpaceX, as repeatedly noted by the article.
Branson insists he will fly this year
In an interview for USA Today Richard Branson once again repeated his expectation that he will fly in space on SpaceShipTwo before the end of the year.
It sounds like they plan three test flights with their new engine, followed by Branson’s public relations stunt. Even if this plan happens, however, I do not see them ready to fly paying passengers, as they will probably need more test flights to make sure the ship and its engine are truly trustworthy.
What private manned spaceship will NASA pick?
Speculation grows on the upcoming down-select decision by NASA of its manned commercial space program.
Next up is the announcement of the transition to the Commercial Crew Transportation Capability (CCtCap) contracts, to be announced later this month, or early in September, depending on political direction. Although the source selection process is obviously an internal debate, with its results embargoed until the time of the NASA announcement, it is hoped that two of the commercial crew providers will move forward with additional funding.
At the ASAP meeting, Ms. Lueders expressed “NASA’s desire to continue the partnerships even after the announcement, including with companies not selected.” That continued association may be in the form of unfunded Space Act Agreements (SAA), not unlike that which Blue Origin is currently working under, as it develops a crew capsule outside of the trio working with CCiCAP funding. “People are recognizing the value of competition and have an appreciation for shared knowledge,” added Ms. Lueders. “NASA has learned from the companies and the companies have learned from NASA. It would be a big plus to continue the relationships.”
As to which companies are likely to win through to the CCtCap phase, that is a tightly kept secret. However, over recent months, sources have noted NASA’s strong affection toward the multi-capable Dream Chaser, while SpaceX has a growing track record with its Falcon 9 and cargo-Dragon combinations via its Commercial Resupply Services (CRS) missions. [emphasis mine]
My sense in the last few months has also leaned heavily in favor of Dragon and Dream Chaser, both of whom appear to be moving forward with construction at a fast pace. Boeing meanwhile has instead made it seem that it wishes to invest as little capital in its project as possible, unless it wins the competition. While the first two companies have unveiled real hardware, Boeing continues to show us mostly mock-ups.
Cygnus completes mission to ISS
Cygnus has successfully completed its cargo mission to ISS, burning up upon re-entry on Sunday.
The story includes images of the re-entry taken by astronauts on ISS.
Cygnus leaves ISS
After a month docked to ISS the latest Cygnus cargo freighter has unberthed in preparation for a Sunday deorbit.
New footage of the Falcon 9 soft spashdown
SpaceX has released new additional footage showing the controlled descent and soft spash down of the first stage of its Falcon 9 rocket during its July launch. I’ve posted it below.
As they note on their webpage, “Towards the end of the video, the camera operator attempted to zoom in and unfortunately lost sight of the stage and was unable to capture the tip over into the water.” Nonetheless, the controlled nature of the stage’s descent says that they succeeded, and need only try to do this over land to prove they can recover their first stage.
Russia to build new satellite communications cluster
The competition heats up: The Putin government’s newly released draft plan for Russia’s space industry includes the development of a new communications satellite constellation.
In addition to encrypted mobile communications, the Ellips satellites will support air-traffic control and traditional fixed communications. Reflecting its dual (civilian and military) application, the Ellips project would be funded jointly by the Russian space agency, Roskosmos, and by the Russian Ministry of Defense at a price tag of 65.6 billion rubles to develop and deploy the constellation.
The article then goes on to detail at length the problems the Russian communications satellite industry has had for the past two decades, including their inability to build satellites that will last in orbit as long as their competitors.
Another look at why ULA’s CEO stepped down
Why did ULA’s CEO step down, and did SpaceX or the Atlas 5’s dependence on Russian engines play a part?
Very worthwhile reading, as it suggests that not only is the competition from SpaceX a major factor, so was ULA’s effort to monopolize the military launch industry as well as monopolize its access to the Russian engines, denying their use by Orbital Sciences.
And to this I say, thank god for competition. It always shakes things up in a good way.
Worldview-3 in orbit
The competition heats up: Worldview-3, launched yesterday, has been successfully activated and can now provide commercial and private customers images of the Earth with resolution comparable to military intelligence satellites.
The sensor package on WorldView-3 will be able to image objects with a ground sample distance of 31 cm (12 in.). “So we can tell you if it’s a truck, SUV or a regular car,” says Kumar Navulur, director of next-generation products at DigitalGlobe. “If there’s a high contrast we can identify features of fine scale,” he adds, giving examples of markings in a parking lot or “a tomato plant in a backyard in Asia.”
Obviously, this has both good and bad possibilities. Nonetheless, its availability increases the value of the space-based industry.
