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.
