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.

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.

Climate experts are now calling for an end to the regularly scheduled mega-climate summits.

Good news: Climate experts are now calling for an end to the regularly scheduled mega-climate summits.

That these summits haven’t accomplished anything but allow climate bureaucrats to burn tons of airplane fossil fuel to gather in some of the world’s nicest warm weather cities during the winter — thereby making them all look like hypocrites — is not the reason these experts want to cancel the summits. They want to cancel the summits because the summits aren’t getting them the results they want: strict regulation on the lives of everyone else.

Nowhere does the article address the simple fact that in the past three years, since the release of the climategate emails, the creditability of the entire climate change field has gone to zero. The public doesn’t buy their sales pitch anymore, and thus neither do politicians, which is why no one is willing to make a deal at these summits. No one believes anything these climate experts are saying, especially since they have refused to clean up the corruption within their field.

Sequestration and NASA

9:49 am

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 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.
