My Book Interview

It’s available on Youtube now.

[Update a couple minutes later]

Here’s one of the brilliant comments over there:

he just sounds like a typical neo con who would prefer to send cheap chinese labor into space rather than waste money on returning white men to their families.
same type who wants more young americans to die for israel.

This is a sign of a broken brain.

BTW, fun fact. That picture of the book? It’s virtual, created by PJTV. It doesn’t yet exist in physical form, but it should next week, and it should look exactly like that.

Hazardous Asteroids

may be more common than we thought:

The scientific orthodoxy said that a Chelyabinsk-size event ought to happen every 140 years or so, but Brown saw several such events in the historical record.

Famously, a large object exploded over the Tunguska region of Siberia in 1908. But there have been less-heralded impacts, including one on Aug. 3, 1963, when an asteroid created a powerful airburst off the coast of South Africa.

“Any one of these taken separately I think you can dismiss as a one-off. But now when we look at it as a whole, over a hundred years, we see these large impactors more frequently than we would expect,” said Brown, whose paper appeared in Nature.

But our response, and actions to become a space-faring civilization, remains pathetic.

The Dream Chaser Test

A report from Joel Achenbach, who’s doing a space project for the WaPo.

As I note on Twitter, Sirangelo’s comments aren’t spinning a failure. The vehicle met its test objectives, other than the ability to get it back, sans a lot of bondo. But as with SpaceX’s loss of their first stage in the ocean, they got the data they needed to move forward. And at least they’re flying and testing, something that NASA has been too risk averse to do of late.

Dream Chaser

Ouch:

…the Commercial Crew prospect – after enjoying a perfect flight in the air – suffered a mechanical failure during landing, resulting in her flipping over on the runway.

Hopefully it’s repairable.

[Update mid-afternoon]

Here’s the official statement from Sierra Nevada, trying to put the best face on things. And Alan Boyle is reporting that preliminary reports indicate that it will be fixable. “The pilot would have walked away.”

It’s interesting that they did the test on a Saturday. I wouldn’t have thought that Dryden employees would be thrilled about working weekends. Though maybe it’s a better day for getting airspace clearance. We used to do a lot of weekend flying with the T-39 for parabolic flight out of Mojave, because the Air Force was more flexible in terms of giving us a big box of air to work with.
