North Korea launched its rocket early Wednesday, despite indications earlier in the week that they were delaying the launch due to technical problems.

It appears those “technical problems” were a feint to distract everyone just prior to launch. Based on radar data it also appears the rocket did put an object into orbit.

Glide tests of Sierra Nevada’s Dream Chaser shuttle are now scheduled to begin in the first quarter of 2013.

Glide tests of Sierra Nevada’s Dream Chaser shuttle are now scheduled to begin in the first quarter of 2013.

The vehicle they will be flying is only a prototype built expressly for these unmanned tests. A separate flight model is under construction and will be used for later manned suborbital tests, followed by a third vehicle built for orbital flights.

If you and a friend happen to have $1.4 billion, the new private company Golden Spike wants to take you to the Moon.

The competition heats up: If you and a friend happen to have $1.4 billion, the new private company Golden Spike wants to take you to the Moon.

Golden Spike’s news release said the venture would make use of existing rockets as well as commercial spacecraft that are currently under development to send expeditions to the lunar surface, with the estimated cost of a two-person lunar surface mission starting at $1.4 billion.

There will be a lot of press stories about this. And it is good, as it illustrates again the increasing shift from government-run space missions to a robust private industry. The idea of a private company doing this is no longer considered absurd but perfectly reasonable.

Whether Golden Spike itself will do it, however, is another thing entirely. Please forgive me if I reserve the right to be a little skeptical at this point.

The Pentagon has decided to buy its launch services from more than just Boeing and Lockheed Martin.

The competition heats up: The Pentagon has decided to buy its launch services from more than just Boeing and Lockheed Martin.

Under the new plan, the Air Force can buy as many as 14 launches over the next five years from possible bidders such as Space Exploration Technologies Corp, or SpaceX, and Orbital Sciences Corp . The service may also buy as many as 36 launches from United Launch Alliance, the Lockheed-Boeing venture, with an option to purchase the other 14 launches if the competitors haven’t been certified to launch military and spy satellites that can cost up to $1 billion each.

Originally the military planned to purchase all of its launches from Boeing and Lockheed. Political pressure from SpaceX has now forced them to widen the competition, or at least, make noises that they are doing so. If you read the above paragraph closely the plan still favors the original two companies and is strongly stacked to hand all the launches over to them anyway.

Update: My pessimism above was premature. SpaceX has been awarded a contract for two launches under this new policy.

North Korea has placed the first stage of its own rocket on the launchpad in preparation for a test flight later this month.

North Korea has placed the first stage of its own rocket on the launchpad in preparation for a test flight later this month.

Japan, South Korea, the United States, and the United Kingdom (as indicated in the article above) have protested this launch, as well as Russia and China. Interestingly, no one has objected to the South Korea’s effort to build its own orbital rocket, which tells us a great deal about the differences between the two Koreas.

Space tourism — in a balloon.

Space tourism — in a balloon.

A newly successful test of a balloon could allow paying human customers to enjoy stunning Earth views and the weightless astronaut experience by 2014. The test balloon carried a humanoid robot up to an altitude of almost 20 miles (32 kilometers) on Nov. 12 — just a few miles shy of where skydiver Felix Baumgartner leaped from during his “space dive” in October. Startup Zero 2 Infinity wants to eventually offer hours of flight time for space tourists to do whatever they want in a near-space environment.

Ticket prices are $143K. And they have a list of customers who have already plunked down deposits.

SpaceX and Stratolaunch have parted ways.

SpaceX and Stratolaunch have parted ways.

In the original plan, Stratolaunch would build the first stage, the biggest airplane every built, which would lift the second stage, SpaceX’s Falcon 9, into the air. It appears, however, that the modifications required to make the Falcon 9 work in this configuration were not in SpaceX’s interest, so the company backed out and Stratolaunch has instead made a deal with Orbital Sciences to provide the second stage rocket.

Impressive radar images of near-Earth asteroid 2007 PA8 were taken during its recent fly-by of Earth.

Impressive radar images of near-Earth asteroid 2007 PA8 were taken during its recent fly-by of Earth.

The images … reveal possible craters, boulders, an irregular, asymmetric shape, and very slow rotation. The asteroid measures approximately one mile wide (about 1.6 kilometers).

The asteroid poses no threat to Earth. The resolution of the images, however, is astonishing, especially considering it was done by radar.

A Russian Proton rocket, scheduled for launch in late December, is being replaced because of damage sustained during transport from its factory.

A Russian Proton rocket, scheduled for launch in late December, is being replaced because of damage sustained during transport from its factory.

This is not the first time this has happened. In 2010 a Soyuz capsule had to be replaced for the same reason. Modern television journalism (if one can call it that) would immediately ask “Is this a trend?” I instead wonder what the details are in both cases, which unfortunately are not available.

Boeing indicated today that it is considering increasing its investment in its CST-100 manned capsule in order to accelerate its development.

Good news: Boeing indicated today that it is considering increasing its investment in its CST-100 manned capsule in order to accelerate its development.

I suspect that, after Boeing in September let leak the idea that they might shelve CST-100 if the space agency didn’t give them more money, NASA management instead told them in no uncertain terms that if they didn’t show a more serious commitment to building CST-100, they might lose the contract altogether.

Cracks have been found in the first Orion capsule intended to fly in space.

8:01 pm

Government space marches on! Cracks have been found in the first Orion capsule intended to fly in space.

The cracks were discovered during a proof pressure test the week of Nov. 5. Proof testing, in which a pressure vessel is subject to stresses greater than those it is expected to encounter during routine use, is one of the many preflight tests NASA is performing on Orion to certify the craft is safe for astronauts, agency spokeswoman Rachel Kraft said. “The cracks are in three adjacent, radial ribs of this integrally machined, aluminum bulkhead,” Kraft wrote in an email. “This hardware will be repaired and will not need to be remanufactured.”

In meetings today the European Space Agency has decided to upgrade Ariane 5 rather than immediately build a new Ariane 6 rocket.

In meetings today the European Space Agency (ESA) has decided to upgrade Ariane 5 rather than immediately build a new Ariane 6 rocket.

Normally I would label this story as an example of “the competition heating up.” In this case, however, I don’t see how an upgrade of Ariane 5 can possibly be competitive. The rocket has been so expensive to operate that — even though it has dominated the launch market for years and is very reliable — ESA has had to subsidize its cost. It has never made a profit. I don’t see how they can reconfigure it enough to bring its cost down to compete with Falcon 9. In other words, they are trying to put lipstick on a pig.

Nor is this surprising. Arianespace is a government-run business, operated like a committee with the member nations of ESA all having a say. Under this arrangement, it is difficult if not impossible to get a quick and efficient decision. Moreover, political concerns will often outweigh issues of efficiency and profits.

In the open competitive market of privately-run companies that the launch market is becoming, I am very skeptical this kind of business can survive.
