A Pioneer, Not Forgotten

Here’s the obit at the WaPo for Len Cormier.

As a staffer with the Academy in 1957, Mr. Cormier was in attendance at the International Geophysical Year proceedings when the Soviets surprised the world with the launch of Sputnik.

The event made a tremendous impression on him, his family said. He decided then to pursue better access to space through affordable, reusable space vehicles.

He was an early visionary. Others will have to pick up his torch now.

Fortunately, a lot of other people now recognize the need:

The National Coalition for CATS, working with leading figures across the space community, will collaborate over the next twelve weeks to develop a “National Declaration for Cheap and reliable Access to Space (CATS).” The CEOs of non-profit and for-profit companies will be invited to sign the Declaration, and will deliver this declaration to the next President of the U.S. after the November election.

Unfortunately, I won’t be able to attend NewSpace, which starts tomorrow in Washington, and where this will be announced, due to financial constraints. It will be the first conference I’ve missed in a while.

Thirty-Nine Years Ago

On July 16th, 1969, the largest rocket ever built thundered off the launch pad at Cape Canaveral, delivering three men and the equipment and supplies they would need to land two of them on the moon and return the three of them safely to earth, fulfilling the national goal declared eight years earlier. The anniversary of the landing is this coming Sunday.

NASA Employee Bleg

Can anyone at the agency go on the record (with PAO permission) and tell me why they think that sending ISS to the moon is a bad idea? I’m working on a piece (I think it’s a bad idea, myself, and have some better ones). Email me at the upper-left email.

More Fear Mongering

Mike Griffin again disquisites on the Yellow Peril.

Well, actually he doesn’t. Here’s all he says (unless there’s some elaboration to which the BBC is privy, but we are not):

Speaking to the BBC News website during a visit to London, Dr Griffin said: “Certainly it is possible that if China wants to put people on the Moon, and if it wishes to do so before the United States, it certainly can. As a matter of technical capability, it absolutely can.”

What does that mean? If he means that if China made it as much of a priority as we did during Apollo, and if we continue on our own disastrous plans, that they could reverse engineer what we did and put some Taikonauts on the moon before NASA lands astronauts, sure.

But how likely is that? And even if it happened, what’s the big deal? We were first on the moon, they were second. Big whoop. There’s no way on their current technological trajectory to do it in any sustainable way, and even if they did, there’s nothing they could realistically do there that would constitute a threat to us, either in terms of national security, or our own ability to do things there on our own pace.

My take?

It is extremely unlikely–the Chinese are not fools. They know how much it will cost to do a manned lunar mission, and it’s not a high priority, particularly when their economy is potentially a house of cards (something not made better by the current energy prices, which will result in either a curtailing of their fuel subsidies, or a decline in economic growth, or both). If and when they are serious about going to the moon, it will be quite obvious, and we’ll have plenty of time to do something about it if we think that it’s actually a problem.

But Mike apparently thinks that he’ll have a better chance of getting increased funding for Apollo on Steroids if he can frighten uninformed people about the Chinese taking over the moon.

I’m Shocked

Orion, already overweight, just got heavier:

“Preliminary estimates show that if this 30-40% [turbulence] heating augmentation heating is applied to the aerothermodynamic database the heat shield mass may increase up to 20%,” says an internal NASA report obtained by Flightglobal.

I wonder if, instead of using an ablator, a tile system would be lighter? It would be more maintenance intensive (particularly with water landings), but it wouldn’t be as bad as the Shuttle, because many of the tiles would be symmetrical and more mass producible. We were never really allowed to do this trade in Phase B at Northrop Grumman–NASA just told us they were going to supply the TPS.

I’m actually quite surprised at this–I would have thought that they’d have modeling an ablative shield down to a science by now. Apollo was way overdesigned, because they didn’t have any experience or good analytical tools to indicate how much shielding they needed. If you look at the heat shield on an Apollo capsule, you can see that it is just slightly charred, with most of it unburned; it could have done a couple more missions without refurbishment or replacement. But based on that experience, we should have been able to predict the optimal weight of an ablator designed to come back from the moon pretty well, and years ago. How did this come up just before PDR?

Anyway, now they have unexpected weight growth in the program at the same time that they have weight and performance problems with the Ares 1. And apparently there are budget problems at LM, as well, if this report is true:

The ORION contractor is overrunning. The minions are out of money. Where can 20-30% more funds be dredged up to cover this miscarriage? You guessed it…the little man.

The minions have let the contractor off the hook for meeting its small business obligations this year. The same obligations that were bid as part of the winning proposal, ostensibly offering a better package than the opposing team, are now null and void. As a result, some of those little companies will start disappearing, lacking jobs and income.

They seem to be achieving the trifecta–failing on performance, schedule and budget. It’s a program manager’s nightmare.

Some further thoughts over at Gravity Loss:

What will the payload landed on the moon be? What propellants are used? What is the Altair’s or Orion’s mass? And work back from there to TLI mass and ultimately to launch from Earth, all with generous margins. And it has seemed that a certain cycle has formed. First a solution on Ares I is based on some logic linking it to Shuttle hardware, infrastructure or Ares V with common elements, which should save a lot of money and time and keep the workforce etc etc. Somewhat later, rumors about a severe performance shortfall on either launcher start circulating. Then after a while NASA announces a new configuration where the commonality is disrupted. And again forward we go.

Unfortunately, the concepts seemed to be driven more by politics than engineering. That was often the case in Apollo, too. The Manned Spaceflight Center could have remained at Langley, but there were political reasons to move it to Texas. Marshall didn’t have to be in Huntsville–they could have moved the rocket team at Redstone to somewhere else (e.g., the Cape, whose location really was driven by geography and not politics). But there were two differences in Apollo. It had essentially unlimited budget, and its success was politically important. Neither applies to the VSE, yet NASA, by Mike Griffin’s own admission when he announced the architecture, not only chose to do Apollo over again, but to do it “on steroids.”
