SpaceShipTwo successfully completed an unpowered glide test yesterday, testing the dynamics and plumbing of the ship’s new engines.
They pumped inert liquid through the plumbing to make sure it functioned in flight. The flight itself tested the balance and position of the new engine.
Assuming the results from these tests are good, expect powered flights quite soon.
A report today in Russia says that the investigation into the Soyuz launch failure last week that while the Russian Fregat upper stage fired correctly in attempting to place the two Galileo GPS satellites into orbit, its software was programmed for the wrong orbit.
In a press conference today to tout the development of the SLS rocket, NASA finally admitted that the rocket’s first flight has been delayed a year until 2018, as had been rumored for months.
The cost? $7 billion more from now until that first launch, a number that does not include the billions already spent. I once again note that the entire commercial program, both manned and cargo, has cost less than that, from start to finish, and includes the entire manifest of actual cargo flights to ISS.
Beginning in 2016, the Russian military will stop using its Rokot launcher, switching to Soyuz and Angara rockets instead.
The reason? Rokot relies on some imported parts, while Soyuz and Angara are build entirely in Russia.
It is interesting how fast the Russians are moving to stop their dependence on foreign parts, compared to the United States. Rather than try to build Russian-built parts for Rokot, they have taken the simplest and fastest approach and simply switched rockets.
In the U.S. Congress is instead demanding that a new rocket engine be build for Atlas 5 to replace the Russian engine, an expensive and time-consuming process. Wouldn’t it make more sense to say buy-buy to Atlas 5 and just switch to the Falcon 9?
The competition heats up: An Israeli start-up is building a satellite tugboat that could be used to move stranded satellites to their proper orbits.
The planned satellite, once built and deployed, should be able to rendezvous with in-orbit satellites and propel them into new orbits, give them course corrections, or steer them towards what’s known as the “graveyard orbit” – a decommissioned satellite graveyard some 300km above their usual height of 36,000 kilometers over the equator. This fuel saving can extend a communications satellite’s life.
The company says its tugboat design could be a possible solution to two stranded Galileo Project satellites, now in possibly unusable orbits following a launch malfunction over the weekend.
The spacecraft would use an ion engine for propulsion.

The Rosetta team has begun releasing more close-up images of Comet 67P/C-G taken by the spacecraft. The image to the right was taken by the navigation camera, but rather than capture the entire nucleus in a single image the camera is now zoomed in and taking a mosaic of four images. This picture is one quarter of that mosaic.
Note the boulders and the sharp peaks in the image. The boulders are important to map for planning Philae’s landing site. The sharp peaks suggest recent outgassing.
The competition heats up: Orbital Sciences expects within a year to get government approval to use its Antares rocket to launch sun-synchronous satellites from its launch facility at Wallops Island, Virginia.
Currently Antares is used to launch cargo resupply missions to the international space station, whose orbital inclination — the angle at which it passes over the equator — of 51.6 degrees dictates that the rocket follow a southeasterly flight path over the Atlantic Ocean. To reach high-inclination orbits, the vehicle would presumably need to fly more directly toward the equator.
Among the details to be settled is the exact configuration of the Antares rocket Orbital would use to place satellites into sun-synchronous orbits, which are commonly used for Earth observation missions. The Antares rockets flown to date have been two-stage vehicles, but the company offers three-stage versions for missions with more stringent orbital-insertion accuracy or high-energy requirements.
The issue here is making sure the rocket stays clear of population areas during launch. An almost due south launch path, needed for polar orbit from Wallops Island, would pass this test.
SpaceX has scrubbed a commercial launch that had been scheduled for Wednesday.
No explanation was provided, but it is likely that the company and its commercial partners decided to give themselves more time to study the issues that caused the Falcon 9R test rocket to destroy itself on Friday.
The second test flight in an Air Force program to research hypersonic flight failed when its booster rocket was intentionally destroyed for safety reasons immediately after launch.
It was the second test of the Advanced Hypersonic Weapon, a program managed by U.S. Army Space and Missile Defense Command/Army Forces Strategic Command to develop a conventional deep-strike munition that travels through the atmosphere on a nonballistic trajectory. In its first flight, the vehicle lifted off from Pacific Missile Range Facility in Hawaii and flew a nonballistic, glide trajectory at hypersonic speeds toward the Reagan Test Site at Kwajalein Atoll — some 4,000 kilometers away — where it arrived about 30 minutes later.
The competition heats up: A rocket launch start-up created by former SpaceX engineers seeks to build their own Falcon 1 rocket for the small satellite market.
Their rocket, called Firefly, will use a number of new and old technological ideas. The highlighted words in this paragraph, however, stood out to me the most:
Just as Firefly is drawing on a lot of government research in its aerospike technology, the company is using a key element of the SpaceX Merlin engine—the pintle injector—in its new engine’s combustion chamber. Markusic, who jumped ship from NASA to SpaceX after the agency sent him to Kwajalein Atoll in the Marshall Islands to observe the first flight of the Falcon 1, says he started working on the technology—also used on the Apollo program’s lunar-descent engine —at SpaceX and when he was developing a liquid-fuel alternative to the hybrid engine used on Virgin Galactic’s SpaceShipTwo. [emphasis mine]
It only took one trip to see SpaceX in operation for this NASA engineer to become a former NASA engineer.
A Russian news story today suggests that they are leaning strongly to continuing their partnership with the United States on ISS beyond 2020.
“The issue of Russia’s participation at the ISS after 2020 remains open, but there is a 90-percent chance that the state’s leadership will agree to participate in the project further,” [Izvestia] wrote, citing a source at Russia’s Federal Space Agency Roscosmos.
This report gives a better overview of the debate going on with Russia’s government and space agency. If they abandon ISS the work they have already done on new modules for the station will have to be written off, and it appears assembling their own station from those modules will be too expensive and take too long.
It also looks like NASA offered them a second year long mission if they stuck around.
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.
