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 a few minutes before the announcement]

[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.

Artificial Spleens And Genetic Surgery

This seems like a big breakthrough, not just for people without spleens, but for iatrogenic disease in hospitals:

To test the device, Ingber and his team infected rats with either E. coli or Staphylococcus aureus and filtered blood from some of the animals through the biospleen. Five hours after infection, 89% of the rats whose blood had been filtered were still alive, compared with only 14% of those that were infected but not treated. The researchers found that the device had removed more than 90% of the bacteria from the rats’ blood. The rats whose blood had been filtered also had less inflammation in their lungs and other organs, suggesting they would be less prone to sepsis.

The researchers then tested whether the biospleen could handle the volume of blood in an average adult human — about 5 litres. They ran human blood containing a mixture of bacteria and fungi through the biospleen at a rate of 1 litre per hour, and found that the device removed most of the pathogens within five hours.

That degree of efficacy is probably enough to control an infection, Ingber says. Once the biospleen has removed most pathogens from the blood, antibiotics and the immune system can fight off remaining traces of infection — such as pathogens lodged in the organs, he says.To test the device, Ingber and his team infected rats with either E. coli or Staphylococcus aureus and filtered blood from some of the animals through the biospleen.

Note that it could also be effective against ebola.

On another front, eliminating bad proteins using RNA interference.

Faster, please.

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.
