The recent youtube video showing an eagle swooping down to grab a toddler was faked.
The uncertainty of imagery: The recent youtube viral video showing an eagle swooping down to grab a toddler was faked.
Based on this example alone, it is becoming increasingly possible to fake a news story. You better have multiple sources on any strange event or else take it with a grain of salt.

NASA has named the impact site where the two GRAIL spacecraft hit the Moon today after American astronaut Sally Ride.
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.

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 2 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.
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.

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.

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.

It is worth a look, as the building is quite strange-looking and actually stands out in the New York skyline, something you would think would be difficult for a new skyscraper to do.

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 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.

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.

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.
