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.

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 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.

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

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.

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.
