I have a piece up on that subject over at Reason. It’s a reprise of some of the arguments I make in the book, which I now expect to be available next week (my printer screwed up). I’d hoped to have them available for SpaceUp LA this weekend, but that’s not going to happen.

The Inner Solar System
Rick Boozer (who has a book out on the waste of SLS/Orion), says that it’s time to send Americans.
Meanwhile, Bob Crippen is spinning fairy tales about SLS:
The combination of SLS and Orion will effectively establish a highway to the entire solar system.
It will be obsolete before it flies.
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.
The Barriers To Deep Space Exploration
The Marshall Institute is going to have a forum on the subject. However, considering that all the panelists (not to mention the moderator) have a dog in the SLS/Orion fight, I’m not encouraged that the discussion will be very interesting, when SLS/Orion are actually the biggest barriers.
#HumansInSpace
If you want to provide input to the committee on human spaceflight, you can tweet it to them tomorrow.
Not sure that you can have a useful policy discussion in 140 characters…
Falcon 9 Heavy
An ominous first flight, by a major SpaceX investor.
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.
SpaceX’s Methane Engine
I’d note, though, that 661,000 lbf is not 300K kilograms — it’s about three meganewtons.
Electronics In The Air
Some thoughts on email and battery conservation in airplanes.
Also from Achenbach: a nice review of Gravity (with spoilers, for those who, like me, haven’t yet seen it).
The Space Debris Problem
Can we fix it by taxing it?
