Ominous

As Clark notes, this isn’t directly related to space transportation regulation, but you can see it coming:

The proposed regulation, titled the Large Aircraft Security Program, would require owners of those aircraft to obtain permission from TSA to operate their own personal aircraft every time they carry passengers. Additionally, all flight crews would be required to undergo fingerprinting and a background check, all passengers would have to be vetted against the government’s terrorist watch lists, and numerous security requirements would be imposed on airports serving these “large” aircraft. EAA adamantly opposes this regulation and urges all members to respond to TSA…

“…We thank the TSA for agreeing with the many industry group and EAA members’ requests for an extension, providing an additional two months to study and react to the proposal,” said Doug Macnair, EAA vice president of government relations. “This proposal would be an unprecedented restriction on the freedom of movement for private U.S. citizens. It would also, for the first time, require governmental review and authority before a person could operate his/her own personal transportation conveyance.

First they came after the private aircraft pilots, and I said nothing, because I wasn’t a private aircraft pilot.

Talking To Mike

Irene Klotz has an interview with the (hopefully) outgoing NASA administrator:

I would be willing to continue on as administrator under the right circumstances. The circumstances include a recognition of the fact that two successive Congresses — one Republician and one Democrat — have strongly endorsed, hugely endorsed, the path NASA is on: Finish the station, retire the shuttle, return to the moon, establish a base on the moon, look outward to the near-Earth asteroids and on to Mars. That’s the path we’re on. I think it’s the right path.

I think for 35 years since the Nixon administration we’ve been on the wrong path. It took the loss of Columbia and Admiral Gehman’s (Columbia Accident Investigation Board) report highlighting the strategic issues to get us on the right path. We’re there. I personally will not be party to taking us off that path. Someone else may wish to, but I do not.

What Dr. Griffin doesn’t understand is that, in his disastrous architecture choices, and decision to waste money developing a new unneeded launch system, it is he himself who has taken us off that path.

I also have to say that I think that this particular criticism by Keith Cowing is (as is often the case) over the top and ridiculous. It’s perfectly clear what he meant–that with all of the other problems facing the country right now, Shuttle retirement per se isn’t going to be a top priority. But it is an issue that will no doubt be dealt with by the transition team.

Propellant Depot Dreams

Rob Coppinger says that they are in fact, a fantasy (though he doesn’t explain why they require “unobtainium“).

Clark Lindsey ably responds. I think that there are several problems with Rob’s thesis, but don’t have the time to get into it right now. I will agree with him that there is no current market for them. I hope, though, that (by the same standard) he would agree that there was no market for launch vehicles in 1956. So I fail to see the point.

[Late morning update]

Jon Goff dissects Rob’s piece more thoroughly.

As for Jon’s question about when he started thinking about depots, it may have been at Space Access in (I think) 2005, when I gave an impromptu talk on the subject, as a result of my work with Dallas and Boeing on CE&R (work that was completely ignored/rejected when Mike Griffin came in and canned Craig Steidle).

More Thoughts On Destinations

From Henry Spencer:

In its early years, the only form of manned space exploration it favoured was an (international) Mars expedition. All other ideas that involved humans in space were counterproductive and undesirable, to hear the Planetary Society tell it.

This obsession with Mars was a bad idea then, and it’s a bad idea now. However, some of the reasons advanced against it strike me as poor – sufficiently poor that they weaken attempts to argue for a more systematic and balanced space effort.

An exclusive focus on Mars does have one thing going for it. If you believe that any resumption of manned space exploration will inevitably end the way Apollo did, with follow-on programmes cancelled and flight-ready hardware consigned to museums as soon as the programme’s first objective is met, then choosing the most interesting single destination makes sense.

However . . . haven’t we learned anything from doing that once? To me, it makes far more sense to try to build a programme that won’t crash and burn as soon as it scores its first goal. That means systematically building capabilities and infrastructure, and doing first things first even if they aren’t the most exciting parts.

Unfortunately, we don’t seem to have the societal patience necessary to do the unexciting parts, at least if the government is paying for it. Which is why we have to get private industry going ASAP.

[Early afternoon update]

I mentioned yesterday that Paul Spudis wasn’t impressed with Lou Friedman’s thoughts. He’s similarly unimpressed with The Planetary Society’s new roadmap.

[Another update a few minutes later]

Jeff Plescia has been leaving this message in comments at various places (I’ve seen it at NASA Watch and Space Politics]

As a participant in the workshop sponsored by the Planetary Society at Stanford University in February, 2008, I feel obliged to make some comments with respect to what is said in portions of the Planetary Society document “Beyond the Moon A New Roadmap for Human Space Exploration.”

Page 5 contains the statement:
“Among the conclusions of this group is that ‘the purpose of sustained human exploration is to go to Mars and beyond,’ and that a series of intermediate destinations, each with its own intrinsic value, should be established as steps toward that goal. The consensus statements and viewpoints expressed by this group of experts form the basis for the principles and recommendations contained in this document.”

This statement is a blatant and intentionally dishonest misrepresentation of the recommendations and sentiments of the group.

We had extensive discussions about what the conclusion of the workshop might be. While the conclusion reported in the Roadmap was clearly the predisposition of several members of the group, particularly the organizers, it was definitively and clearly not the consensus of the group as a whole. In fact, when these words (or words to the same effect) were suggested, the group clearly indicated to the organizers that they should not be used because they were inaccurate. However, the organizers chose to ignore the group’s wishes at the end of the workshop, at the International Astronautical Congress and in the Roadmap in portraying the results of the workshop. This has occurred despite the fact that members of the group pointed out after the workshop press release that such statements were inappropriate and incorrect.

For what it’s worth. Thanks, Lou.

Maybe it’s like the climate change “consensus,” from which many scientists are now running.

Failure To Tether

One of the astronauts lost a toolbag during EVA servicing:

Piper noticed that one of the two grease guns in her bag had exploded, spreading the dark, dry grease all over her camera and gloves. The grease, called Braycote, is a durable, non-flamable lubricant tough enough to handle the extreme temperatures and vacuum of space. It is needed to lubricate the cranky joint which has been grinding for more than a year.

In the midst of trying to clean up the mess, the bag of tools floated away from her. Views from a camera mounted on her helmet show it drifting slowly off towards the back of the station, some 200 miles above the earth.

“Oh, great,” she exclaimed in frustration.

I assume that by “exploded” they just mean “escaped under pressure,” and not literally a supersonic combustion.

A truly spacefaring nation would have a routine means of going and retrieving something like this. Instead, it becomes one more piece of space junk to track until it eventually enters the atmosphere, probably months or years from now.

One In Thirty?

Is that really the loss-of-crew probability for an ISS trip with Ares/Orion?

I could buy that number for a lunar mission, but if that’s just for a crew changeout, they seem to be managing to spend billions on a new launch vehicle that is less safe than Shuttle.

How could it be? As one of the commenters speculates over there, they may have pulled a lot of redundancy out to save weight when they ran out of margin on both the launcher and the capsule. Also, as I think I’ve mentioned before, it may be that they’ve figured out that the Launch Abort System actually adds more risk than it removes, given the dozens of hazards it introduces, over half of which can happen on an otherwise nominal mission.

Anyway, if true, it’s just one more reason to abort this monstrosity now, before it wastes any more time or money.

Some Brief Space Policy Advice To The Obama Team

Which in fact I’ll probably be offering in the next days and weeks, since I actually know several of them quite well.

If you want to know how to get the VSE back on track, you could do a lot worse than to simply go back and reread the Aldridge Commission Report. Mike Griffin doesn’t seem to have done so, or if he did, he largely ignored its recommendations, with the one exception being developing a heavy lifter (which was the one main thing that the commission got wrong).

Apostasy

Jack Schmitt has resigned from The Planetary Society over their destinational dispute. As I noted the other day, to argue about destinations at all is to miss the point.

I agree with most of his points, other than the need for heavy lift. And I absolutely agree that making it an international venture would be the kiss of death, at least in terms of meeting schedules or making it affordable, other than setting up propellant depots that can take deliveries from a wide range of sources, including international and commercial. But the Mars hardware and expeditions should be national in nature. We need competition, not “cooperation.”
