    It was a tragedy, an accident, a misfortune.

    A vehicle accident that kills 7 people is not a disaster, no matter how expensive the vehicle is or how famous the people are.

  3. Shuttle tiles on Canadian Company Developing New Space Shuttle · · Score: 2, Informative

    Shuttle tiles were used cuz in the 1970's the metal alloys to withstand the >4000 F reentry temps (allowing for hot reentry in failure/emergencies) were either too expensive or not yet invented. In the 1990's NASA JPL developed a metal alloy that can take the heat without losing strength. Titanium may melt at 3500F, but it loses strength long before that.
    Unfortunately, the NASA program was scrapped after a few test flights of working 1/2 scale models.
    The knife-edge surfaces are needed for hypersonic flight. The shuttle does not "fly" at mach umpteen, it "falls", belly first, and ablates orbital speed in exchange for a huge plasma cone that can probably be heard on radio out to pluto.
    modern tech can probably build a high-temp reentry surface that can actually fly under (limited) control to any chosen landing spot - making the New York - Canberra run an hour-and-a-half or so.

    I've worked at NASA JSC since 1979. There was a history archive building (or actually, several). I worked in one of them on a very slow second shift, watching data reduction programs design the leading edge of the shuttle wing, among other things. I browsed the library for reading material while I waited for tapes to spin and printers to print. (And card readers to read, too!)
    All the plans were there. When they shut down the office, they dumped boxes and boxes of duplicate records, books, etc, that had been collected as the various parts of Apollo, Apollo-Soyuz, Skylab, etc shutdown. I got a chronology of Skylab. Another coworker got books on Apollo and Gemini, along with drafts of the first space shuttle - the one called Dynasoar, and its descendents, from back in the 1950's.

  11. What was I thinking? on No Formal Risk Analysis of Hubble Rescue by NASA · · Score: 1

    I was thinking the story was about the title: "Backing a bad HUBBLE decision". shuttle-to-shuttle docking has no impact on Hubble repair mission, because Hubble isn't a space shuttle.
    Since no one has ever done a "rescue mission" of one manned space craft using another manned space craft (with the possible exception of a few of the trips up to Mir), designing everything needed to make it work, and to make sure it would work under most plausible failure modes would take far longer than Hubble can wait.
    If one shuttle has one thousand things that can go wrong, then two shuttles have 1000 * 1000 = One Million things that can go wrong. Combinations thereof can be fatal, even if each taken separately is not. This is nontrivial to analyze.
    Personally, I don't think it has anything to do with Hubble - I think it was cut so that US can get out of the space shuttle era as quickly as possible. They'd probably abandon the station also if they didn't have international commitments.
    As for the long repair mission, I was addressing a point made in the article - that a supply depot alongside the shuttle could somehow help rescue the shuttle.
    The risk assessment may have been simply a review of all of the criticality one issues that have been waivered in order to do the job. The list is pretty long.
    That's a personal guess with no insight into what actually went into the decision, and does not reflect the position of my employer.
    Yes, I work at NASA, for a contractor.
    The article is trying to spin an unpopular decision as being not just unpopular, but somehow flawed. That may be - but planners up and down the ladder had to remanifest more space flights and payloads then the entire US manned space program even attempted for its first 20 years, and they had to do it in a very, very short time in order to meet top level expectations and public pressure. This on top of actually investigating the Columbia accident and redesigning the ground process, the flight hardware, software and procedures, and Chuthulu knows what else in under about a year. And, other than actual launches, everything else keeps going until the decisions are made - Crew Avionics Upgrade, Pad refitting, main engine work, etc.
    The decision basis, my wild guess here, wasn't "is it safe", but "can even the effort to analyze it be justified, considering how muddy the water is now?"
    Doing too many things in a dangerous project is a risk in itself, even if the goals' risks are mitigated.

    I hope so, I don't want to think that it's too expensive to save lives...the article rewords this same position 7 times in a row as if there's something wrong with this position.
    As Gregory told Congress, "Administrator O'Keefe made a very conscious, deliberate and well-informed decision that the shuttle would not service the Hubble."
    ... "NASA historian Steven Dick ... revealed that, in fact, no formal risk analysis had been completed."
    This doesn't say anyone claimed there was a formal document generated. One can be well-informed without lots of formal paperwork.
    The decision was made (by O'Keefe) based on what he perceived was the risk."
    Sometimes it's just a no-brainer. Why strain over it?
    For example, according to ... anonymous, one company actually proposed using an updated version of the module that was built in the 1990s to allow the shuttle to dock with Russian Mir space station...so the crews could be transferred from one spacecraft to the other in a shirt-sleeve environment...
    Docking between human life support systems is irrelevant. Hubble is not a human-bearing spacecraft, and has no "inside" to dock to, no airlock. The piece of equipment mentioned here is as useless to fixing Hubble as it would be to fixing the engine of your lawnmower.
    O'Keefe testified before the National Academy of Sciences in June 2004, he made no mention of this docking module option, telling academy panel members that the only method available for crew rescue was a spacewalk
    Since there's no "inside" of Hubble, the repairs have to be made from the outside of Hubble, like your car has to be repaired from the *outside* of the engine, this was and will always be true. So a spacewalk is the only way. Kinda like getting wet is the only way to swim.
    Nor has NASA ever apparently considered the idea of using one of the several available supply modules to supplement the provisions of an orbiting shuttle...such a module could be used as a supply depot for a damaged shuttle - a form of safe haven ..."
    A "supply depot" is not a "safe haven" - it's a spare parts cabinet. A "safe haven" would be a second working space craft that could replicate all the functions of the first, otherwise, if something goes wrong, you have two sets of problems: the limits of the disabled vehicle, and the limits of the "safe haven". If they both can't do the same thing at any point, you're dead. Redundancy for safety must be planned in total in advance, or it's useless.
    ...thereby extending its time in orbit ...
    Having a safe haven does not lengthen the time the orbiter can stay in orbit - same as the "supply depot" situation. The redundancy is not there to be relied on for primary mission objectives, but to bail you out if needed.
    Two such supply modules...are under development ...
    Now we know why they weren't considered. They don't exist yet.
    As Rep. Mark Udall, D-Colo., noted during those same science committee hearings, "If we're unwilling to take the risks to go to Hubble, then what does that say about (our willingness to mount) a moon and eventual Mars mission?
    It says that we recognize that the shuttle's old and busted technology left over from the 1970's and if we're gonna do something bold, we gotta do it with new hotness. I could go on, but I think I've made my points....

    I believe the license that ATT and IBM agreed to allows IBM to create and own any derivative they want. That ownership would naturally include licensing and distribution rights. (else it wouldn't be "ownership")
    GPL developers choose to not prohibit, but to conditionally allow distribution of exact copies and derivatives. As a copyright owner, it is their right. This is not viral. This is an exercise of the owner's exclusive right to control their own property.

I was a computer operator then, a wee lad shoving punch cards thru the card reader.
    The CDC beastie had 10 "peripheral processors" (Math processors), about 256K bytes, ran at about 4Hz (That last number may be wrong), and required chilled water and by golly lots of it to stay cool.

That is, it's made of dozens of separate units that can be unscrewed (on the ground of course, not in space), reshaped, adjusted to a new leading edge line or curve as desired. I had to run hundreds of cards into that cyber for each run of the model. The runs took all night, and each run was for a slightly different shape of leading edge. It took several years of computer time to design a smooth curve that didn't have hot spots or where the max Q wouldn't cause the Carbon Carbon structure to buckle. 18000 mph plasma is hot and hits really hard.
    15 years later, the Russians launch their shuttle (unmanned prototype) the leading edge of the wing was exactly matching the US shuttle...
