The competition heats up: Because of the Russian situation in the Ukraine, Canada has rejected a launch contract with Russia and signed India to do the launch instead.
No word on the rocket Canda will use, but I suspect it will be India’s smaller rocket, tested and more dependable. Their geosynchronous rocket, GSLV, is still in the testing stage.
An evening pause: Recorded live.
Hat tip to Frank.

The Japanese space agency has now promised to make sure that future launches of its new low cost Epsilon rocket will not leave its upper stages in orbit as space junk.
Epsilon’s first flight, which was a success, left two large objects — the rocket’s upper stage and a smaller post-boost stage — in an orbit with a perigee of some 800 kilometers, meaning neither will fall into the atmosphere for a century or longer. In the meantime, they will add to the population of orbiting garbage that poses a threat to active satellites traversing this orbit.
Japan has signed international agreements requiring them to not create space junk, so on future launches they are promising to make sure the upper stages are released in low enough orbits that they will quickly decay and burn up in the atmosphere.
The competition heats up: Orbital Sciences has announced that it will make a decision in November on replacing the Russian rocket engine that it uses in its Antares commercial rocket.
In a presentation at the 65th International Astronautical Congress here, Orbital Executive Vice President Frank Culbertson said the engine decision is linked to the company’s proposal for NASA’s Commercial Resupply Services (CRS)2 competition. NASA issued the request for proposals for CRS2 on Sept. 26, with responses due Nov. 14. “We’ll make sure we’ll have a decision on that before we submit the proposal,” Culbertson said when asked about the status of the engine decision.
Orbital has been weighing for several months a replacement for the AJ-26 engines that Antares currently uses. Those engines, provided by Aerojet Rocketdyne, are refurbished versions of Soviet-era NK-33 engines originally designed for the N-1 lunar rocket developed in the 1960s.
The company is considering several proposals, including one from ATK, which is in the process of merging with Orbital at this very moment.
The article also notes that Orbital recognizes that the use of Russian engines will likely work against them in the competition to win the next ISS cargo contract, and that if they don’t have a plan to replace those engines it is quite possible that NASA will go with a different company, such as Sierra Nevada, when it awards that contract.
As I said already, oh how I love competition.
The investigation into the failure of a Russian Soyuz rocket to place two European Galileo GPS satellites into the correct orbit has found that it was caused by the faulty installation of fuel lines on the Fregat upper stage.
The failure was as simple as clamping together a cold helium line with the hydrazine fuel line, causing the hydrazine to freeze long enough to upset the Fregat stage’s orientation and cause the two satellites’ release into an orbit that is both too low and in the wrong inclination, officials said. One official said the Euro-Russian board of inquiry into the failure discovered that one in four Fregat upper stages at prime contractor Moscow-based NPO Lavochkin had the same faulty installation. ,,,,
Government and officials said the commission is debating how to proceed now that it knows that, as expected, the Fregat failure was not one of design, but of assembly and quality control. [emphasis mine]
In other words, 1 in 4 Fregat upper stations were routinely assembled improperly and no one noticed. The investigation also found that this assembly problem had existed on several past launches but because of the orbital requirements it had fortunately not caused any problems.
I want to emphasize that these kind of sloppy assembly issues have been occurring at a number of different Russian factories and different Russian companies. It seems to be systemic to the entire Russian aerospace industry, and it also appears to be getting worse.
The competition heats up: Sierra Nevada and Stratolaunch have signed an agreement to use a 3/4 scale version of Dream Chaser as the manned vehicle launched by Stratolaunch’s giant first stage airplane.
The Dream Chaser is a reusable, lifting-body spacecraft capable of crewed or autonomous flight. Dream Chaser is the only lifting-body spacecraft capable of a runway landing, anywhere in the world. Stratolaunch Systems is a Paul G. Allen project dedicated to developing an air-launch system that will revolutionize space transportation by providing orbital access to space at lower costs, with greater safety and more flexibility.
As designed, the Dream Chaser-Stratolauncher human spaceflight system can carry a crew of three astronauts to LEO destinations. This versatile system can also be tailored for un-crewed space missions, including science missions, light cargo transportation or suborbital point-to-point transportation. The scaled crewed spacecraft design is based on SNC’s full-scale Dream Chaser vehicle which, for the past four years, has undergone development and flight tests as part of NASA’s Commercial Crew Program.
More information is expected to be released about this partnership at the International Astronautical Congress taking place in Toronto this week.
Summing up, however, this partnership is a blatant challenge to NASA’s Orion/SLS system as well as its its commercial crew capsules built by Boeing and SpaceX. Sierra Nevada and Stratolaunch are essentially telling the world that they are going to build their own manned reusable vehicle, and that it is going to be better than anyone else’s.
Oh how I love competition. It sure makes things happen quickly.
An evening pause: Hat tip Danae.
The competition heats up: Sierra Nevada (SNC) has announced a new effort to gain international customers for its Dream Chaser manned spacecraft.
From the press release:
SNC’s Global Project offers clients across the globe access to low Earth orbit (LEO) without the time, resources and financial burden of developing the necessary capabilities or infrastructure to support a mature human spaceflight program. The Global Project utilizes the Dream Chaser spacecraft as a baseline vehicle which, in turn, can be customized by the client for an array of missions to support government, commercial, academic and international goals. The individual mission customization of the Global Project can be applied to both crewed and uncrewed variants for a single dedicated mission or suite of missions.
This is excellent news, as it tells us that the company is not giving up on the spacecraft, and intends to push hard to finish it. Not only are they working make it a viable product to many customers and thus obtain the construction financing to build it outside of NASA’s manned program, they also appear ready to bid on NASA’s second round of cargo launches, using Dream Chaser as an unmanned cargo freighter to ISS.
In fact, I would not be surprised if NASA chooses Dream Chaser over Dragon for that second round of cargo deliveries. Dragon is slated for the manned flights, so the agency will need another vehicle to replace it. Why not give the contract to Sierra Nevada, thus providing NASA with two manned vehicles and three cargo vehicles, all capable of accessing the station.
All in all, this increasingly looks like a win-win situation for everyone.
In a letter written by a bi-partisan group of California legislators, Congress is pressuring the Air Force to replace the Russian engines on its Atlas rocket, and do to it competitively.
“While it is important that we invest in new technology, the problem of Russian reliance calls for an immediate solution,” states the Sept. 22 letter, which was signed by 32 of California’s 53 members of the U.S. House of Representatives. … In the letter, the House members said they are “troubled by the Department’s willingness to continue sourcing this engine from the Russian government, apparently in the hope that the situation with Russia does not deteriorate further, and that Russia chooses to continue supporting U.S. military launches — while it ignores American sources of engine technology. “We strongly encourage you to recognize that the United States — and specifically, California — today produces technology that exceeds any capability offered by Russian systems,” the letter said. “It is time for the Department to look to these existing U.S. engine manufacturers and launch vehicle providers.”
This letter suggests to me that SpaceX has won its battle with the Air Force and is going to get some launch contracts. It also suggests that ULA and Blue Origin will likely be able to get the funding from Congress to finance the design and construction of the replacement engine they have jointly proposed.
An evening pause: I don’t know if it’s possible to two instruments to be farther apart in range. Yet they work together here very nicely. Nigel Wood plays the soprillo while Jim Cheek plays the tubax.

The competition heats up: A Proton rocket has successfully placed two classified Russian satellites into orbit, the first time a Proton has launched since a May 16 launch failure.
