More details on Virgin Galactic’s first glide test of SpaceShipTwo with its rocket motor attached.
SpaceShipTwo has successfully completed its first glide test flight with its rocket motor attached.
Now that they know the spacecraft glides properly with the extra weight of the rocket, this sets the stage for the first powered flight.
Russia today successfully launched a new three man crew toward ISS.
The science team for Cassini has released a spectacular mosiac of Saturn and its rings, backlit by the Sun.
NASA has named the impact site where the two GRAIL spacecraft hit the Moon today after American astronaut Sally Ride.
Though this is a nice gesture, the entire public relations campaign surrounding the GRAIL impact today has been one of the more overhyped exercises at NASA. The impact is going to provide very little new science, and is necessary because no lunar orbit is stable and the spacecraft will eventually crash into the Moon anyway. Better to do it under controlled circumstances. To make such a big deal about it however is hardly interesting, especially since this has been done repeatedly by practically every lunar orbiter.
Orbital Sciences has begun testing the loading and unloading of fuel for the first stage of its Antares rocket at Wallops Island, Maryland.
This is good, but the questions about the Antares’ system for ejecting its shroud after launch still remain, threatening the rest of the schedule.
NASA used Orbital Sciences’ Taurus XL rocket for the failed launch of its Glory climate satellite in 2011, even though the agency knew the company had not fixed the problem that caused the loss of the Orbiting Carbon Observatory in 2009.
The investigators believed there was as much as a 50% chance the faulty component — a fairing separation system for ejecting the protective shroud that covered the satellite during launch — would fail again. Sadly, it did, destroying Glory. More significant for the future, however is this:
Other Orbital vehicles, including the air-launched Pegasus and a new Antares rocket, use a version of the same fairing separation system that is most likely responsible for the combined $700 million loss of two key climate-study satellites. Orbital’s original name for Antares was Taurus II.
So far, NASA has not accepted the Antares shroud-separation configuration for operational flights. Dulles, Va.-based Orbital says it has made a number of changes to its frangible joint fairing separation system in the wake of the Glory launch failure, including modifications to the frangible rail used on Antares. The company is developing that rocket under NASA’s Commercial Orbital Transportation Services (COTS) program to carry cargo to the International Space Station (ISS).
If NASA isn’t satisfied with Orbital’s design changes to this system, it could significantly delay the launch of Cygnus and Antares to ISS.
Update: I had mistakenly referred to the Taurus 2 in the first sentence when the rocket used to launch Glory and OCO was the Taurus XL. This is now corrected.
China’s Chang’e 2 lunar probe, now out of lunar orbit, did a fly-by of the 3 mile wide asteroid Toutatis as it zipped past the Earth last week, resulting in some spectacular images.
Launched on October 1, 2010, Chang’e 2 orbited the Moon for 8 months before being redirected last year to the L2 Lagrange point, roughly a million miles on the side of Earth opposite the Sun. But when it left L2 last April, Western observers suspected the spacecraft was heading deeper interplanetary space. It didn’t take long to realize that Chang’e 2 was bound for Toutatis.
This is an example of a very smart re-use of a space probe.
By the way, the first fly-by of another planet took place fifty years ago this week.
Here we go again. Yesterday an aerospace organization, Aerospace Industries Association, released a sixteen page report [pdf] claiming that NASA will lose 20,500 jobs and NOAA 2,500 if the federal government goes over the “fiscal cliff” and sequestration happens.
Immediately, a slew of news articles xeroxed this report to pound home this point, noting the job loses for the specific cities of each newspaper and how disaster awaits the country if sequestration is allowed to take place and we go over that blessed “fiscal cliff”:
The trouble is, this is all hogwash and bad journalism.

The satellite that North Korea launched early Wednesday appears to be tumbling out of control, according to unnamed U.S. officials.
The Defense Department does have the capability to detect a tumbling satellite, especially if its solar panels are visible, though I must emphasize that the information here is so vague it hardly means anything. Regardless, the real issue here is not that North Korea put a working satellite into orbit, but that it now has the rocket capability to put anything into orbit. For us this is not a good thing: A rogue nation that is trying to build nuclear weapons that is also officially still at war with our ally South Korea now has this capability.
SpaceX has pinpointed the cause of the Falcon 9 engine shutdown during its October 7 Dragon launch.
At the moment, however, they are not telling anyone what that cause is. They are telling us that the next Dragon launch is going to happen in late February or early March, which is slightly earlier than previous reports.
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.
The first X-37B to fly in space was successfully placed in orbit today for the second time.
North Korea, having postponed the launch for technical reasons, has apparently begun removing the rocket from the launchpad.
Oy. A design problem in Curiosity’s drill makes it a threat to short out the electronics of the entire rover at some point in the future.
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.
More bad news for Russia: Kazakhstan is considering cancelling the lease that allows Russia to use the launch facilities in Baikonur.
North Korea has halted preparations for its planned rocket launch.
Bad news for Russia: During a launch yesterday the upper stage of a Proton rocket failed to put the satellite into its proper orbit.
With this, the third failure in the past 16 months for the Briz-M upper stage, I expect that the Proton’s customers will continue to flee, as has Echostar.
A fuel leak has now been pinpointed as the cause of the Delta 4 rocket launch problem in October.
It now appears that the next launch of the X-37B is set for Tuesday, December 11.
This would mean that the engine problems that occurred on a Delta 4 rocket launch in October have been resolved.
A tour of the impact craters that Curiosity created when it landed on Mars.
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.
A new National Research Council report released yesterday says that NASA lacks focus nor can it complete the missions it has with the resources available.

The planet that never sleeps: Looking at the Earth from space at night.
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.
NASA announced yesterday plans to launch by 2020 a twin rover of Curiosity to Mars.
Though it makes sense to use the same designs again, saving money, I must admit a personal lack of excitement about this announcement. First, I have doubts it will fly because of the federal government’s budget woes. Second, it is kind of a replacement for the much more challenging and exciting missions to Titan and Europa that the Obama administration killed when they slashed the planetary budget last year.
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.
South Korea scrubbed the launch of its own homemade rocket last night.
This was their second attempt to get the rocket, called Naro-1, off the ground. More details about the rocket and today’s scrub here.
