The competition heats up: Orbital Sciences has confirmed a September 15 launch date for the first Cygnus capsule mission to ISS.
The Russians have begun a six-hour spacewalk today on ISS to prepare the station for the arrival of a new Russian module.
The article also outlines the continuing investigation into the American spacesuit problem from the last American spacewalk, where an astronaut’s suit began to fill with water from an unknown source. It appears they have pinpointed the most likely cause of the leak, but appear to be having problems recreating the failure.
Update: The Russian spacewalk is over, all tasks completed.
For the first time since 1975 the Navy and NASA have teamed up to practice the ocean recovery of a manned capsule.
This practice was with an Orion capsule mockup.
The engineering tests to try to save Kepler have found that the mission is essentially over.
A headline at this New York Times article, “NASA’s Kepler Mended, but May Never Fully Recover” is wrong, as the telescope has not been “mended.” They have found they might be able to do some limited science, at the most. NASA is going to review this possibility, weighing the cost versus the benefit, and decide in the fall.
The decision to not compete: Why did the builders of One World Trade Center in New York settle on fourth place?
The article includes some nice history about the race in New York in the first half of the 20th century to build the tallest skyscraper.
Russia has concluded its investigation into last month’s Proton launch failure and now says its next launch will be on September 15.
While the investigation pinpointed the problem — the installation of sensors upside down — none of the news reports about this investigation have mentioned what any corrective actions the Russians are taking. Meanwhile, at least one unnamed Russian engineer is questioning the schedule and the thoroughness of the investigation.
Engineers have identified twelve asteroids that could be captured with today’s technology.
Their number one most easily moved space rock is named 2006 RH120. A single rocket burn in 2021 would be enough to place this roughly 4-meter-wide asteroid into orbit around a Lagrange point by 2026. NASA could then launch people to study this object (which would barely be bigger than the astronauts themselves) and learn about its history.

The competition heats up: Sierra Nevada has completed ground tow tests of its Dream Chaser engineering test vehicle.
Video at the link. They will now begin flight drop tests this fall.
Today I have an op-ed in the Wall Street Journal, entitled “No liftoff for these space flights of fancy.” It is essentially a more detailed reworking of my rant on the John Batchelor Show on July 30.
My point is that the federal space program mandated by Congress, the Space Launch System (SLS), is never going to go anywhere, and is nothing but pork that should be cut as fast as possible. (See my essay from November 2011 on how NASA and the federal government can better use this money to get more accomplished in space, for less.)
The comments to the article have generally been positive and in agreement. Those who disagree mostly question the $14 billion cost per launch that I claim SLS will cost. That number comes from John Strickland’s very detailed analysis of what it will cost to build, complete, and operate SLS. However, it doesn’t require much thoughtful analysis to realize that this number is not unreasonable.

The competition heats up: ATK has joined Stratolaunch, winning a contract to provide solid rocket motors for company’s proposed second stage air-launched rocket.
Stratolaunch’s first stage will take off from a runway, and will be the largest airplane ever built. The second stage, which Orbital Sciences is building and which ATK is now be a partner, will be released from this airplane and then ignite.
A detailed look at the questions and rumors that continue to swirl around the engineering status of SpaceShipTwo.
If you want to get an idea why Virgin Galactic has not done any powered flights of SpaceShipTwo so far this summer you must read this article.
Japan’s fourth unmanned cargo freighter to ISS was successfully berthed to the station today.
Virgin Galactic did another glide test of SpaceShipTwo today.
I wonder, however, why there have been no powered flight tests so far this summer. After their first powered flight in May, it was expected they would begin a series of such flights, leading up to the first passenger flights at the end of the year. Instead, nothing.
This lack of flights feeds the long standing rumors that there are problems with SpaceShipTwo’s engine.
An update on Dawn in its journey from the asteroids Vesta to Ceres. Bottom line:
Dawn is 18 million kilometers (11 million miles) from Vesta and 50 million kilometers (31 million miles) from Ceres. It is also 3.47 AU (519 million kilometers or 322 million miles) from Earth, or 1,310 times as far as the moon and 3.42 times as far as the sun today. Radio signals, traveling at the universal limit of the speed of light, take 58 minutes to make the round trip.
Russia has announced that they will resume Proton rocket launches in September.
Though they have pinpointed the specific cause of the most recent launch failure, they have not yet announced any remedial actions. Note also the expected number of launches for the rest of the year, 4 to 5, is down from earlier expectations.
Meanwhile, in Kazakhstan, an official in that country’s space program has been arrested for taking bribes.
An update on the effort to bring Kepler back to life.
Japan today successfully launched its fourth unmanned cargo freighter to ISS.
The rendezvous and berthing is scheduled for August 9. Besides supplies, the HTV-4 carries more equipment for NASA’s robotic refueling demonstration project on ISS.
The competition cools down: Armadillo Aerospace closes down.
It is important to recognize that developing a new private industry is not easy, and that many more companies will fail than succeed. That reality, however, does not prove that freedom and private enterprise are bad ideas, merely that they carry great risks.
The competition heats up: SpaceX has confirmed that it plans to begin vertical take-off and landing tests of a full scale Falcon 9 first stage.
The tests would be in New Mexico’s spaceport, and are essentially a scaled up version of the Grasshopper tests the company has been doing in Texas. It appears they are going to do these ground-up tests in conjunction with attempts on each future Falcon 9 launch to land the first stage.
The state of SLS construction.
The article is mostly focused on the engineering challenges of building a new rocket out of old pieces of the space shuttle. Kind of reminds me of Frankenstein. Nonetheless, I do get the impression for the first time that this heavy lift rocket will be built, and will fly at least once.
After that, however, I expect it to die from lack of funds. In fact, its history will probably parallel that of the Soviet Union’s Energia rocket, which flew twice, once to launch their shuttle copycat Buran and once to lift a failed payload whose purpose has never been clearly revealed. Soon thereafter came bankruptcy and the end of the Soviet Union, which couldn’t afford such a monstrosity. SLS will likely see a similar fate.
The competition heats up: SpaceX has signed a contract with MDA to launch all three of Canada’s next generation Radarsat satellites.
MDA’s willingness to go with SpaceX prior to the September 5 launch of its Cassiope satellite on the Falcon 9 illustrates again the confidence they have in SpaceX. At the same time, this contract is for launches expected to occur around 2018, which is a long way away. Much can happen till then, including the possibility that SpaceX will go bust.
In other words, right now it is the successful launch of Falcon 9 that is of significance, not these new contracts. Only if those launches succeed will these contracts then become really significant.
On Friday an astronaut on ISS controlled and steered a rover on Earth.
While zipping around Earth several hundred miles above the planet’s surface, European Space Agency astronaut Luca Parmitano drove a 220-pound (100 kilograms) rover across a moon-mimicking landscape here at NASA’s Ames Research Center, even ordering the robot to deploy a simulated film-based radio telescope antenna.
Scientists have finalized their flyby plans of Pluto when New Horizons arrives there in 2015.
A Russian Progress freighter has arrived at ISS with supplies and a spacesuit repair kit for fixing one American spacesuit.
The competition heats up: Arianespace’s Ariane 5 rocket successfully launched two commercial satellites into orbit late yesterday.
The box that built the modern world.
A really fascinating, detailed, and well-written article about something none of us thinks about but has made our lives infinitely better.
The new solar space observatory IRIS has taken its first pictures.
The effort to bring Kepler back to life does not look good.
