Russia is suspending its space tourist program, for fairly obvious reasons. An NYT story notes that the obsolete but reliable computers driving the shuttle are to be examined as part of the inquiry. But most interestingly, a story in Aviation Week claims that a tracking camera trained on the shuttle detected damage to the wing prior to the breakup.

    As with the Challenger disaster, there are many smart people trying to determine the cause of the accident. In addition to the wreckage, there are memos, notes, films, and other media to review. Investigations take time, and regardless of the desire to find an immediate smoking gun,I anticipate NASA will release an official report no sooner than may. Right now we have several media "experts" offering their opinions.

      Houston IS the blackbox.

      When you have something flying at Mach 2 after a vertical ascent of only 60-some seconds, no blackbox we can make would survive any longer than radio transmissions captured by warehouse-sized surveilance systems on the ground can. Then, there's all the other surveilance on the ground and in the air by astronomers (pros and amateur) and USAF.

      NASA, the same day of the disaster, explained all that in the Q&A session.

      The current shuttle design would gain little from a blackbox-like device.

    "We continue to recover crew remains and we are handling that process with the utmost care, the utmost respect and dignity," said Ronald Dittemore, shuttle program manager.

  3. In Orbit Inspections? by Flamesplash · · Score: 5, Insightful

    I wonder if NASA will start making in orbit inspections of shuttles part of the flight plan. While things like this are obviously rare they are real and deadly.

    I wonder how long it would take an astronaut to correctly inspect a shuttle in orbit.

  4. Fairly Obvious Reasons? by ArsSineArtificio · · Score: 5, Insightful
    Russia is suspending its space tourist program, for fairly obvious reasons.

    It's not really obvious why they're doing it. The article implies, but doesn't state, that it's because they now need to put cargo where the third, "passenger" seat would go on a Soyuz capsule.

    Some people have suggested they're doing it because "space is now unsafe", which makes absolutely no sense.

    In this case, a stable, well-known and quite familiar technology is "the best kit we can." If it ain't broke, don't fix it. Upgrading for the sake of getting "newer" components is more likely to cause safety hazards than leaving older, perfectly good systems in place.

    It seems unlikely that computers were to blame for this, but the kit in the shuttle is pretty old - if we're going to ask people to risk their lives like this we must give them the best kit we can.


    that would be suicide... The older computers running in the shuttles are rock solid, space proven, and reliable. which are very different from anything that intel or AMD makes. the older and slower computers are doing the job fine without baing overloaded or needing to read sensors any faster. Remember, this is flight control computers... I'd rather have a known 99.999999999% uptime processor that was designed in the 80's running my spacecraft or aircraft than any of this unstable junk we use today.

    outdated in the articles terms means it's nothing but a comment by an uneducated person trying to get their 15 seconds of fame.

    The Software would have a larger potential for blame... I.E. the programmer did not make klaxons go off when sensors give bad readings, or there was any instance of throwing out data.

    Until I see a report that states that the current computers on board are running at > 50% capacity and are getting near the overtaxed point then I'll believe it. until then it's fake news.

  7. Yes, but is one of them Richard Feynman? by kfg · · Score: 5, Insightful

    It's interesting to read Richard's story of the investigation of the first shuttle disaster, and his realization that the process was political, not scientific.

    He had a great deal of trouble, as an official investigator, just being *allowed* to investigate, and of course to release his findings he had to engage in what amounted to guerilla tactics.

    The end fate of the Morton-Thiokol engineers who "blew the whistle" must stand as some sort of object lesson in this case as well.

    One would hope that steps are being taken to prenvent another go 'round of this shabby and shameful incident in American space history.

  8. I concur. by s20451 · · Score: 5, Insightful

    Soyuz is characterized in the popular media as an aging, broken-down spacecraft, but the fact is that it is one of the most reliable and efficient manned spacecraft that has ever been produced. The Soyuz has a launch escape system which has been used once, in 1983, to blast the crew away from their exploding rocket (in the words of one site, "The crew landed close to the launch site, badly bruised after surviving nearly 20g acceleration, but they were still alive.") This is unlike the shuttle, in which escape is impossible for the first two minutes of flight, while the solid boosters (which can't be turned off) are firing. Soyuz has not had a fatal accident since 1971, and has had no major safety issue since 1988. Personally, given the choice between flying on the Shuttle and flying on Soyuz, I would pick the latter.

    Spaceflight tends to reward simple and time-tested designs over new and complex. I have read at least one account suggesting that NASA resurrect the Gemini spacecraft for crew transfer to and from the ISS, since it was one of the most reliable spacecraft the US has ever flown.

  9. Re:Because they didn't plan for it by Zathrus · · Score: 5, Insightful

    They did plan for it.

    From Nasa's Human Space Flight pages:

    The nominal maximum crew size is seven. The middeck can be reconfigured by adding three rescue seats in place of the modular stowage and sleeping provisions. The seating capacity will then accommodate the rescue flight crew of three and a maximum rescued crew of seven.

    Make sure one other shuttle is always ready to go within a week like Atlantis was

    Atlantis wasn't ready to go. It could be pressed into service, but only by eliminating all pre-launch testing. You know, the testing that routinely finds problems in the months prior to launch that have to be fixed and occasionally cause launch delays?

    You want a shuttle ready to go everytime? Ok. You just doubled the cost for every launch. Because keeping a shuttle ready is a huge expense. The environment, even inside a building, is not friendly to the components and continual inspection is necessary for some areas... like the tiles.

    It seems like a simple thing to rig up some camera or whatever to look around the corners.

    It's not a simple thing. They've been trying to design one for ISS and it's problematic. And that's a vehicle that's not designed for reentry.

    As long as you have water, and you can recirculate that pretty low tech, if they don't do that already.

    Oddly enough, Columbia would have been in good shape here... They were actually testing systems to recycle water from waste. See here.

    I expect something like this to be in place before the shuttles are taken in use again

    I don't. Doing so at this stage would kill manned space flight. It's akin to eliminating seafaring exploring from Europe in the 1400s - 1600s because too many people died in the process, and so we won't do any more exploration until the infrastructure is in place to keep them safe. Except that until the exploration has been done it's impossible to put the infrastructure in place.

    I'm not saying that a rescue couldn't have occurred - in fact I posited ways it could have been done (based off statements from NASA no less), but also stated the issues that would have been encountered. Nor am I saying that a rescue shouldn't be attempted in a future case.

    But, realistically, we don't have the infrastructure yet. If we want to be able to prevent this kind of disaster in the future, then we have to do more missions, build more flight systems (hopefully more cost effective to run than the shuttle fleet), and put more permanent installations into space. But all of this is decades down the road... and trying to fix it the other way around is a nearly certain way to kill manned spaceflight all together.
