NASA goes retro with lunar butt plug ideal for probing Uranus
Tim Cavanaugh | August 23, 2006, 4:36pm
The National Aeronautics and Space Administration is going with a classic model for its Orion crew exploration vehicle, designed to carry up to six people to the International Space Station, the moon, and eventually Mars. Take a look at the souped-up Apollo-era capsule, still attached to the Ares rocket that will carry it into space.
And here's a view of the capsule on its own:

"Our team, and all of NASAand, I believe, our countrygrows more excited with every step forward this program takes," Orion Project Manager Skip Hatfield says in a press release. "The future for space exploration is coming quickly."
Orion will be capable of transporting cargo and up to six crew members to and from the International Space Station. It can carry four crewmembers for lunar missions. Later, it can support crew transfers for Mars missions.
Orion borrows its shape from space capsules of the past, but takes advantage of the latest technology in computers, electronics, life support, propulsion and heat protection systems. The capsule's conical shape is the safest and most reliable for re-entering the Earth's atmosphere, especially at the velocities required for a direct return from the moon.
I'll say it takes its shape from space capsules of the past. Dig the CEV with some kind of lunar lander:

And here it is with the International Space Station. If you look really closely you can see your tax dollars being burned up to provide energy for the ISS:

The coolest thing about Orion is the logo:

So it's something. I can't say I'm swept off my feet, but I'm relieved to hear this baby will use "the latest technology in computers," presumably allowing ENIAC's number-crunching power to be used for other tasks. And given the dire struggle to find a replacement for the space shuttle, it's good that at least something is shaping up.
But since the CEV, if all goes according to plan, will essentially end up servicing the ISSa task for which the shuttle was invented in the first placeit does leave a question for future historians to sort out: What will be the legacy of the shuttle? Did it contribute anything to progress in space travel, or was it just a 30-year trip to nowhere? (That's a real question, not a rhetorical question.)

The whole NASA space program gives me conflicts. Much has been said about the technology that's ancient by the time it flies, and of course, the huge budgets, spent in good part just for the propaganda value of being able to say we did it.
Nevertheless, we
did do it, and I have found it an inspiration throughout my life. I don't know if the public at large appreciates the challenges and the efforts to achieve them that any of NASA's projects involve. Certainly, if the equivalent had been done privately, even libertarians would have something to cheer about, wouldn't they?
The Space Shuttle. Hmmmm. At once, a sinkhole for money, and a huge technical accomplishment. The goal was a cheaper, reusable cargo and passenger transport to orbit. It has worked, over a hundred times, although it has never achieved the cost reductions or the launch frequencies hoped for it. Now with one vehicle less than originally anticipated and a scheduled retirement in 2010, it probably never will. As far as lives lost, it's sad. I still can't watch the videos. But I'll bet that any astronaut, if asked, would not have thought a second if asked to make another flight immediately after either of the two disasters. Do commercial and military test pilots have a better record?
But the question is, what is its legacy? In spite of delays, overruns and accidents, it has met its primary objective, and along the way, it has inspired at least techno-geeks like me. I would find it hard to believe that Orion or any other new vehicle did not inherit and build on the lessons learned from the Shuttle. Isn't that legacy enough? There are hundreds of little spin-offs from its development and deployment that benefit us today. Maybe they would have been developed almost as soon without the Shuttle, but the Shuttle gets the credit. More legacy. The Hubble Space telescope would not be returning the pictures it does without the repair missions made possible by the Shuttle. And the Shuttle's mission isn't over yet. It may be too early to close the book on the story of its legacy. Will there ever be a sub-orbital space plane? Orbiting space hotels with the taxis to haul their customers? How much will future space probes, commercial or otherwise, benefit from things like the robotic arms and inspection booms?
If I had the chance to vote on NASA's budget, I'd vote it down every time, in hope that eventually, commercial rockets would achieve essentially the same thing at less cost. Space Ship One hints that that will happen. But ...
I used to live on Long Island. Whenever the Shuttle launched to a high-inclination orbit (e.g., to the ISS) in the evening, seven minutes after launch I could walk out my front door and watch a bright dot of light approach from low in the southeast sky, and as it passed LI, I could see main engine cut-off (MECO) and external tank separation, followed by OMS correction flashes and the tumblings of the tank. I would marvel about the fact that there were from three to seven people on board, and they did that every few months on the average, over and over. Amazing. That spirit in my mind is part of the Shuttle's legacy, too, and it's hard to put a value on it.

Tim,
As someone who works in the industry, I think the COTS program is a much, much better investment than Orion. The COTS program has a couple of key differences:
1-The COTS funding is with firm, fixed-price contracts, with payments only upon acheivement of technical milestones. Orion is "cost-plus" with payments on a regular schedule regardless of actual success.
2-The COTS companies, SpaceX and Rocketplane/Kistler are being required to privately raise a substantial chunk of the money--ie they have "skin in the game".
3-The COTS companies will be building crew/cargo transportation systems that they will own and operate, with the ability to use them for non-government uses. Orion will be used for NASA purposes only, and will be pretty much government operated.
4-The total COTS budget is less than 5% of the budget for Ares I (aka the Shaft) and the CEV, in spite of covering most of the same functionality.
I could go on. There are a couple of good space blogs worth looking at if you're interested. Hobbyspace.com is a good start. I mostly blog about space issues at Selenian Boondocks. There's a blog called COTS Watch that covers a lot of COTS related stuff.....
Anyhow I just think that Ares I is making yet another government funded booster that isn't needed (there are already two other US boosters in its weight class, with two more on the way), and is being pursued in a way that is mostly designed to keep as many Shuttle employees in as many congressional districts continually employed as possible....
Not really much for a libertarian to love. Even COTS could be considered unlibertarian on some levels, but with the fact that NASA isn't going to go away, at least COTS is likely to give a much higher return on investment than Orion is.

Tim: while I have read quite a few books about STS and ISS, my primary source is experience as a science writer in the 1970s and 1980s, when I covered and talked with STS designers, NASA managers, and the relevant Congressional players as well as critics inside and outside the bubble. I'll happily measure that against your tendentious version, which sounds as if it
does come from books.
You handwave about the von Braun agenda (there were
lots of things on the drawing board, and always have been), while back-pedaling away from your initial (and incorrect) formulation. Neatly done.. sorta like introducing a conspiracy theory for rhetorical effect ("I, Tim C, have no evidence for this, mind you. Just saying.")
No, I don't think the shuttle "moved humanity ahead in space" very much. It's the implicit "why not?" on which I think we disagree. I think getting from the state of the art c. 1970 to the levels of cost, operability and total traffic to LEO projected for the Shuttle was (and remains) much harder -- not just technologically, but economically -- than almost any space enthusiast, NASA fan or NewSpace booster, is willing to admit. We're in an expensive and inelastic corner of the trade space, with a long way to go before ROI kicks in. Most of that difficulty is the same whether the challenge is tackled with tax dollars or angel investment, by NASA or by entrepreneurial startups.
On reading your Aug. 20 post, I think we may agree more than we disagree. I too would like to see more space science. And I'm no fan of VSE, a White House mandate which I doubt will be remembered much longer than Poppy's SEI, let alone survive to fruition. But
given that brain-dead mandate, it's pointless to get excited either way about details of the ESAS architecture -- the target of your easy snark (ENIAC, etc.) in this post. I also see in the post some of the "we've just been doing it wrong" handwavery I referred to before; if you don't, let's leave it at that.

I think you're starting from a neat sound-bite formulation ("the Shuttle's only justification is to supply ISS, and ISS's only justification is to give the Shuttle a reason for being") and projecting it backward as history. That's not an unfair snapshot description of the budget/policy corner NASA occupied for some years pre-
Columbia, but it's grotesquely glib as a description of the rationales as the two programs started.
Yes, a manned space station of some kind had always been on the agenda -- not just NASA's or von Braun's, but that of most space cadets since the 1920s. STS, by lowering costs, was supposed to be the enabler not just for that but for anything we might decide to do in space: more and bigger commsats, Hubbles and more ambitious science platforms to be boosted from LEO by Centaur, DoD goodies, etc. Nothing about the STS design was specific to any of the viewgraph space stations kicking around (sans budget) in the 1970s -- hardly what I'd expect if they were joined at the hip to the degree you seem to think.
OK, so the Shuttle flies in 1981, far short of what had been hoped for in 1972. Reagan declares it "operational" a year later after four (!?!) flights, and proceeds
as if it were the cheap, robust space truck we'd wanted. On to commercialization (industry backed away), on to SDI battle stations (couldn't afford to orbit 'em even on the cheapest ELVs, let alone STS), on to a space station (repeatedly down-scoped almost from the beginning as reality sank in), on to a teacher-astronaut... oops.
ISS doesn't prove that a space station is a bad idea; it proves that
any multi-hundred-ton project in LEO, predicated on the Shuttle we'd wanted but built with the one we had, was bound to be way late and way over budget. That NASA, four presidents (and until Columbia, most of Congress and the public) drank some more Kool-Aid and plowed on rather than "cut and run" is regrettable, but as a psychological failing it's hardly unique to space activity. :-(
