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.
If Russia is canning space tourism, does that mean we're stuck with Lance Bass?

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.
I am me...I think
"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.
They died advancing science so we could all live better lives. Let's keep this in mind...
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.

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.
All employees must wash hands before seeking equitable relief.
The O-rings in use on the booster rockets for the Challenger (and previous shuttles) were rated for warm weather, which was acceptable since the launches were in Florida. It was a cold day when Challenger launched. The engineers warned admin that day that the boosters might fail. There had already been numerous delays, so admin launched anyway.

R: That voice. Where have I heard that voice before? B: In about 365 other episodes. But I don't know who it is either.
There is no black box. This was a question at the first technical briefing on Saturday. While they do have various data recorders on board, they aren't hardened to survive a crash. For the most part, they aren't necessary, as all the relevant data is transmitted back to Mission Control in real time. Such information would only allow them to better reconstruct the last few seconds after communications were lost (some of which it turns out they did receive data from, only it was too low-power for them to process at the time). While that may be interesting, the useful information will be from earlier on in the flight when the problem first showed up.
Someone found this really cool article about the group that writes the shuttle software. I've always admired CMM level 5, having spent my entire career at level 1. ;) I wonder if they need more coders.
Secession is the right of all sentient beings.
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.

That Aviation Week article was the best recounting I've seen yet. I get so tired of that period of time between a catastrophic event and the time real information can be disseminated. Looks like I'm not alone
"Draco dormiens nunquam titillandus."
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.
Do not look at laser with remaining good eye.
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.

Just as a point of comparison: The 1675th Soyuz launch took place recently. There have been only two fatal Soyuz accidents, both over 30 years ago. I don't think the Russians have to apologize in any way for their safety record.
Because it takes anywhere from a week to a couple months to get a shuttle ready for flight.
As it happens, Atlantis was on the pad already, but it still would've taken nearly a week to launch with minimal crew (pilot and engineer). Columbia had enough food and water to last half a week... although with rationing they may have been able to extend that sufficiently.
Even so, what do you do then? There's no way to "dock" two shuttles and Columbia didn't have jetpack suits onboard, and I don't believe everyone was rated for EVA. You can make a "jump" from one ship to another, but that's trickier than it sounds... fortunately if you do it right and have the supplies on board then only one person has to do it - you can tether the ships together, as long as their orbits are precisely matched and close enough together. The precisely matched bit is the hard part really - it's going to take several hours to transport crew from one shuttle to the other.
It'd probably be an effort on the level of Apollo 13.
Afterwards you have a shuttle in a slowly degrading orbit that's going to do an uncontrolled burn up in the atmosphere -- although perhaps you can set a navigation program to activate after the crew is saved to ensure splashdown in a safe area (like the Pacific ocean). Dunno. Of course, this would have been better than what did occur.
Things are more like they are now than they ever were before.
Did you actually read the article? Or are you just making assumptions based on the synopsis, which on this site are known to be highly inaccurate?
Quote the article: Plans to send tourists into space have been frozen by Russia after the Columbia shuttle disaster left its Soyuz capsules as the only working link between Earth and the International Space Station.
The point is not that space is any more dangerous as a result of the Columbia disaster. Since NASA has put flights on hold, Russia needs to use more room on the Soyuz capsules to pick up the slack. That leaves less rooms for space tourists. As quoted in the article, a Russian space agency spokesman said, "Space tourism is not a priority. State interests must come first, then commercial interests."
I know that many people on Slashdot don't actually read the articles, but it sure helps to clear up a lot of confusion.
www.timcoleman.com is a total waste of your time. Never go there.
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.

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.
