Musk Versus Bezos

Here’s the story on today’s announcement that ULA is teaming with Blue Origin to develop an RD-180 replacement. Thoughts anon.

[Update a while later, after the presser]

Clearly Jeff Bezos has declared war on Elon Musk. And ULA is showing how desperate it’s become. That’s what disruption looks like. More later, but I have to review our reply to Mann’s latest court filing. Speaking of which, I suspect that he regrets starting this hash tag.

Here’s Joel Achenbach’s take.

Over on Twitter, Trampoline Rocket is speculating that this is vaporware, like Amazon’s drones. He makes a pretty good case.

Here’s Alan Boyle’s take.

Aaaaaand, Aaron Mehta’s take.

Commercial Crew

There’s going to be an announcement at 4PM on NASA TV. Jay Barbree says it’s going to be Boeing and SpaceX. Which if true means two capsules, no wings.

[Update a while later]

Here‘s another similar report from the WaPo.

[Update a few minutes later]

Joel Achenbach has more, including the (bizarre, to me) part of the story about ULA getting a new engine for the Atlas from Blue Origin.

[Late-morning update]

OK, now James Dean is reporting that there will be two full awards, not “leader-follower.” I wonder if they have the money for that with a CR?

[Update just before noon]

Alex Brown has a story at National Journal. Annoyingly, everyone is calling them space “taxis” when, at least for NASA, it’s more of a rental-car model (if you insisted on a new car every time you rented). Also, everyone’s regurgitating NASA’s 2017 date. I’d at least note that SpaceX could possibly fly as early as next year, unless there is something else on the critical path than abort tests. Final point:

Boeing’s program is reported to be further along in its development goals.

I think that Pasztor story is BS. How can Boeing be in the lead when they haven’t even flown anything? I love this:

But people familiar with the process said Boeing, with its greater experience as a NASA contractor, appears to have become the favorite partly because it has met earlier development goals in the same program on time and on budget.

Everyone hits their budget. It’s a fixed-price contract. And who cares if they’re hitting program goals, if those are trivial goals (like design reviews)? How anyone can think that a paper vehicle is ahead of one that’s going to have its abort tests in the next few months?

[Update after the announcement]

Well, no surprises, except amounts. Here’s Eric Berger’s take.

[Update a while later]

Here is Jeff Foust’s story.

Don’t Go To Mars

David Attenborough takes a novel and courageous stand. Let’s “sort out life on earth, first.” [Paywall]

I don’t think I’ve ever heard anyone make that argument before, except a lot of people, for decades.

“America? Let’s sort out life in Europe first.”

“Europe and Asia? Let’s sort out life in Africa, first.”

It’s obviously a mindless prescription for never settling new territory.

Giant Solid Rockets

Yes, let’s keep using them:

In this case, the DM series motors passed all of ATK’s and NASA’s inspections and test firings. It wasn’t until ATK was proceeding toward QM series motor segments that NASA requested more thorough inspections of the QM series motors to determine whether the switch to non-asbestos containing insulation liners was having a previously unseen effect.

“The beauty of the solid rocket motor inspection system is that defects will be found and solutions reached to ensure the motors delivered will perform with the highest reliability,” said Reed. “This is a requirement to ensure SLS is a safe and reliable system for human exploration of deep space.”

Yeah. Right.

The SLS Frenzy

So apparently, the SLF fanbois (and fangirls) going crazy over a giant welder on Twitter.

Anyway, I was rereading this essay I wrote half a decade ago. It was depressing. Here’s how little of some of it I’d have to change to keep it relevant to today.

KSC Versus MSFC

I had an interesting Twitter discussion this morning, that gave me an insight that had been floating around in the back of my mind, but that I’d never articulated, either to myself or others. It sort of crystallized when someone said that Bob Cabana, head of KSC, was an SLS supporter.

One of the tenets of the Apollo Cargo Cult is that we can’t go beyond earth orbit without a really big rocket. The conventional wisdom has been that the biggest constituency for SLS is Marshall, because that’s were it is being developed. But if you think about it, there are a lot of things Marshall could be applied to — it doesn’t have to be developing big rockets (something it hasn’t successfully done in almost four decades). For instance, it could be developing technology and demonstrators for orbital fuel storage and transfer. That would be at least as much in its wheelhouse as SLS.

KSC, on the other hand, has little justification for existence if NASA doesn’t have its own (big) rocket to launch. Without a big rocket, it doesn’t need the VAB, and the VAB and the crawler are really the only unique capability it has, in terms of physical infrastructure. If everything is going up on commercial rockers, even from Pads 39, KSC doesn’t have much to do, other than integrating NASA’s payloads onto them. That’s not a trivial task, but it’s not one that justifies the center’s budget or workforce. So, while Marshall could in theory be redirected to something useful, KSC can’t really. That’s why Nelson supports it so strongly.

It struck me in fact that the VAB is the high cathedral for the cargo cult. What would happen to the religion if it was taken out by a hurricane?
