Oklahoma is going to court over it.
I think this case will have a better chance than the one that wasn’t ripe in the DC Circuit.
Meanwhile, why does the EPA hate blacks and other minorities so much?

The Falcon Failure
Still “no one theory consistent with the data.”
[Update a while later]
Here are more details from Stephen Clark.
Why SpaceX Will Be Flying Again Quickly
Some thoughts from Iain Thomson:
SpaceX doesn’t have those issues; it’s a single company that conceived, designed, built, and flies the Falcon rockets. Finding fault is going to be a lot easier under such circumstances because there’s a single data set and everyone knows everyone else.
The company is packed with highly motivated individuals and has a very flat management structure. Mistakes made are owned up to, and when the issue that caused the loss of the Falcon is identified, you can bet it will be dealt with quickly.
The current SpaceX resupply missions are on hold while this process is worked through. But you’re not going to see the kind of dithering that left the Space Shuttles grounded for 32 long months. If I were a betting man I’d guess the next Falcon will fly in 32 weeks, and maybe sooner.
Very likely sooner, I think. In fact, I think they’ll either figure it out quickly, or not at all. If they can’t figure it out at all, they have a huge dilemma, as I told Leonard David yesterday (he’s working on a piece with quotes from me and others).

Telomere Extension
…turns back aging clock in cultured cells:
“This new approach paves the way toward preventing or treating diseases of aging,” said Blau. “There are also highly debilitating genetic diseases associated with telomere shortening that could benefit from such a potential treatment.”
Blau and her colleagues became interested in telomeres when previous work in her lab showed that the muscle stem cells of boys with Duchenne muscular dystrophy had telomeres that were much shorter than those of boys without the disease. This finding not only has implications for understanding how the cells function — or don’t function — in making new muscle, but it also helps explain the limited ability to grow affected cells in the laboratory for study.
The researchers are now testing their new technique in other types of cells.
“This study is a first step toward the development of telomere extension to improve cell therapies and to possibly treat disorders of accelerated aging in humans,” said John Cooke, MD, PhD. Cooke, a co-author of the study, formerly was a professor of cardiovascular medicine at Stanford. He is now chair of cardiovascular sciences at the Houston Methodist Research Institute.
“We’re working to understand more about the differences among cell types, and how we can overcome those differences to allow this approach to be more universally useful,” said Blau, who also is a member of the Stanford Institute for Stem Cell Biology and Regenerative Medicine.
“One day it may be possible to target muscle stem cells in a patient with Duchenne muscular dystrophy, for example, to extend their telomeres. There are also implications for treating conditions of aging, such as diabetes and heart disease. This has really opened the doors to consider all types of potential uses of this therapy.”
I wonder if there’s some political reason they won’t use the R word? Anyway, faster, please.
NASA’s Upper-Stage Problem
The absurdity of this program knows no bounds. I feel terrible for the NASA and industry managers who have to go through the kabuki of pretending any of this makes any sense.
My Initial Project Status
For those not backers, but interested in what’s happening, I did a project update this morning:
I’m starting to spool up on the project (I expect to actually be funded this week — there’s a two-week delay after the close). Leonard David has a report today that the “Affordable Mars Strategy” report has been published and is available for free download [note: I haven’t actually been able to find the download — all I could find at Leonard’s link was Scott Hubbard’s op-ed — but I think I have the report]. I’ve also been in communication with the authors (specifically, John Baker and Nathan Strange at JPL), and received a lot of material from them last week (some of which may be redundant with the report). I’m planning a trip to Denver next week to (among other things) talk to folks at ULA about integrated vehicle fluids and propellant depots.
The JPL work will provide a foundation for my own analysis, and I’ll probably be discussing it with them. While I think they have a good solution for what they perceive to be their problem, I have fundamentally different top-level requirements.
I would characterize their approach as “Apollo to Mars”: A destination, a date, civil-servant boots on the ground, with a giant government-owned-and-operated rocket, except (unlike Apollo) it is budget constrained. I don’t think that will be any more economically and politically sustainable than Apollo was. I also think, bluntly, as a taxpayer and space enthusiast, that it would not be worth the money.
My approach is to get NASA completely out of the earth-to-orbit business, and to take the savings to develop the technology needed to build a scalable in-space reusable, resilient, affordable transportation architecture, that will enable not simply NASA, but anyone else who wants to, to go to the Red Planet.
And not just to Mars.
SpaceX Failure Effects
They have a long list of customers left in the lurch.
Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds.

Another story, from Eric Berger, with political implications.
[Afternoon update]
The Falcon 9 was at an altitude of approximately 45 km and traveling in excess of 5,000 km per hour when a problem developed in the second stage. SpaceRef can confirm from sources within SpaceX that the Falcon 9 first stage performed nominally i.e. as expected. Indeed, if you watch launch video, you can see that first stage continues to function steady and stable even while the front end of the rocket was destroying itself. That in and of itself is impressive.
According to SpaceX sources telemetry received from the Dragon spacecraft showed that it too was functioning normally after the mishap occurred and this telemetry continued to be sent back from Dragon for a significant period of time.
Despite an earlier statement from NASA to the contrary, SpaceX sources now confirm that the U.S. Air Force Range Safety Officer did initiate a destruct command but that this command was sent 70 seconds after the mishap occurred, as a formal matter of process. There was nothing left to destroy at that point.
That’s probably what confused Senator Nelson, when he said this morning that the Air Force had destroyed the vehicle.
The Falcon Failure
I overslept. Just got up and saw my Twitter feed.
@elonmusk just had his worst birthday ever, I suspect. But it's a good day for Dick Shelby.

My immediate thought: This makes is a lot harder to sell my thesis that we need to start flying crew ASAP. I haven’t changed my mind, but I’ve never claimed that it would be safe to do so, just that it was important to do so. My second thought: Would the launch abort system have worked for this event? I really am surprised at this.

There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause.
— Elon Musk (@elonmusk) June 28, 2015
Unfortunately, it happened before stage separation, so they didn’t get to even attempt a landing.

That's all we can say with confidence right now. Will have more to say following a thorough fault tree analysis.

Second question (per Henry Vanderbilt’s comment): Could capsule have separated absent an LAS? Was the Dragon destroyed by range safety itself?

[Evening update]
Thoughts and history from Stephen Smith:
Humanity reached the Moon in 1969, yet failures and fatalities still happen. They always will.
Today I met a 12-year old from a Colorado middle school who had an experiment aboard SpaceX CRS-7. I told her I was sorry she lost her experiment, but she was undeterred. Grinning from ear to ear, she said, “We’ll build another one and do it again!”
As he notes, so will SpaceX.

A good balanced take from the WaPo.
