Spaceflight Now has the video released by the NTSB.

Blood Vessels
Some evidence that they can actually improve with age. Interesting.
NASA Advisory Council, Day Two
I’m going to switch from listening to NTSB meeting to hear the status on exploration systems at 9 AM PDT. Phil McAlister will be discussing Commercial Crew status later this morning. I would note that in this morning’s meeting in the House, Chairman Culberson was very enthusiastic (as expected) about the Europa mission, but he still insanely imagines that SLS is the solution to it.
The NTSB Meeting On SpaceShipTwo
I’m listening in live now, but Leonard David already has a story up.
[Update a few minutes later]
Doug Messier has the executive summary. Full report won’t be available for a couple weeks.
[Update a while later]
Temporary adjournment to wordsmith final findings. Sumwalt wants to make clear that while it was pilot error (Finding 1), it was an institutional failure at Scaled that made it possible for such an error to be catastrophic. There also seems to be some (IMO, undue) criticism of FAA-AST, and talk of “political pressure” to prematurely issue licenses/waivers. People (including NTSB) need to understand that AST currently has no statutory authority to regulate safety of the spaceflight participants, including crew, and they are chronically under-resourced to carry out the responsibilities that they are authorized to do. In fact, George should be careful what he wishes for, because if the learning period expires this fall, he still won’t have the budget he needs to expand his authority.
One thing that’s not clear yet (to me): If part of the problem was inability to read instruments due to vibration under thrust. If there was a digital readout, that (and other critical information) should be replaced with an actual Mach meter.

Here‘s Jeff Foust’s report.
Light Posting
I’ve been on a telecon all day on the NASA Advisory Council meeting at JPL. Some very interesting discussion on launch and technology issues. I’m generally impressed with the tech plans, except for the absence of serious ISRU.
Politicos Put Graft Before Progress
While this is a good general topic, nowhere is it more true than in human spaceflight:
Sometimes the new competition wins anyway. Uber has been good at generating a large base of mobile customers, then using them to pressure politicians: When New York City Mayor Bill de Blasio went after Uber, Uber used its app to let its users pressure de Blasio.
Happy Uber customer Kate Upton weighed in, producing more pushback than de Blasio could withstand — especially when it turned out he’d gotten over $550,000 in donations from taxicab interests.
Other services aren’t so lucky, and the ability to do an end run around regulators, though welcome, isn’t universal. And if, on top of setting up your lemonade stand, you need licenses, permits, lobbyists and subsidies to make it, not many new lemonade stands will get started. That’s good news for existing lemonade stands, and for the politicians they support, but it’s bad news for everyone else.
Including people who actually want to affordably accomplish things in space.
High Blood Pressure
This looks interesting, but I’d like to see some numbers. Like, how much does it cost, and what kind of reductions are they seeing? I often see studies that amuse me, as though a barely-statisrically-significant 10% risk reduction for some expensive drug with unpleasant side effects is actually worth it.
And is it a permanent solution, or does it require periodic retreatment? Also, are there side effects (like insufficient blood flow to the brain on suddenly standing up)?
Good Space Policy Advice
Stephen Smith has some for the presidential candidates:
U.S. Census statistics show that more people alive now were born after Apollo (185 million) than before (123 million). For the majority of the population, the 1960s Space Age is a page in a history book, and has little personal emotional resonance.
So do yourself and the nation a favor. Don’t invoke Kennedy.
As your campaign staff develops its space policy white paper, begin with a fundamental question — why should people be in space?
Yes.
A New Anti-Body
Could attack several different strains of flu, and make the annual shot obsolete.
I hope so.
El Nino
What effect might it have on California and the drought? It’s hard to imagine we’ll get a rainy season drier than this past one.
