It's not they didn't think about it or haven't tried it. Even in 80's there used to be a nice autonomous vehicle which you could strap on and go for a ride around the shuttle. It doesn't need very very high-tech either. It's fairly easy to design something uses compressed air to whiz around and uses gyroes for attitute. It doesn't have to be big, it doesn't have to be expensive.
The problem is, NASA is very conservative. They like experiments but Astronauts really hate change. Nothing has changed since 1970s and they like it that way.
And Soyuz (the company) is now designing something much larger and useful. At least they are doing something for future. What is NASA's plans for a replacement craft? Well, there's nothing that's usable in 20 years time. Instead NASA is going to fly these shuttles until they all burst into flames in one way or the other.:-(
Effectively flying to ISS is not more dangerous than flying to Hubble. Either way if something happens, 7 people will die. Flying into orbit or descent to earth is no riskier if you are flying from ISS. Even more, ISS' infrastructure will not allow having 7 additional people on board for a medium to long period. Apollo 13 used LM as a lifeboat but they endured pretty harsh conditions for three days. Also usually there aren't enough space suits in a shuttle flight for 7. What if the docking is not possible? In early Salyut flights docking failures were common occurences. One Spacelab mission was cancelled because of a docking problem.
Killing Hubble is a political decision, nothing more. It pleases Bush&Co because it shows NASA's dedication to Bush's crazy Mars plan, frees up resources and makes it clear to all tech-savvy people that Shuttle is a white elephant and it is nothing what was promised in late 70s and early 80s. I'm not saying Shuttle was a while elephant from the start but just because it existed no replacement was properly funded.
About one basket and eggs scenario, unless you send a good amount of mixed-gender people to ISS nothing good will happen if something happens to Earth. I really don't care about some useless seeds of a cocky Astronaut if there are no eggs to fertilise. They can whack themselves to no end in free fall.
GiTS SAC is absolutely beautiful in animation and in story. I started to watch the 2nd season and so far it is going good.
If you read the manga, you'll see that GiTS SAC is much more closer to it than the movie was. I still love the movie but SAC is much better than the movie in story-terms.
So why can they threaten a small group of developers because they use "windows" name in their product? If the trademark is for "Microsoft Windows", then as far as I can see, then can't attack a product not called "wxWindows", not "Microsoft wxWindows". If it were nemd "MX Windows" or "WX Windows", maybe but still the trademark is surely for "MS Windows" or "Microsoft Windows".
It is just not logical and that's why I hate lawyers and laws! Arrrrghhh! My head hurts!
Beacuse this story only gets 75 replies, "Keyless Entries Fail In Las Vegas On Friday" gets around 500 in a shorter time.
I was outraged when I read the story, apparently not everyone thinks the way I do, something has to be done. This is such a stupid thing, after Lindows renaming its product to Lin----, maybe/. users are getting used to these things but this still doesn't make them tolerable. wxWindows has nothing related to MS Windows, apart from possibility of running with it and still Microsoft's lawyers could threathen a group of developers with lawsuits. Lindows was at least a competitor in their OS market. This is just not tolerable.
As one poster stated, MS has a history of using generic names, next big target can be OpenOffice. Then what? Will you stay silent until they knock on your door? Remember what Nazi's did:
First they came for the Communists,
and I didn't speak up, because I wasn't a Communist.
Then they came for the Jews,
and I didn't speak up, because I wasn't a Jew.
Then they came for the trade unionists
and I didn't speak up, because I wasn't a trade unionist.
Then they came for the Catholics,
and I didn't speak up, because I was a Protestant.
Then they came for me,
and by that time there was no one left to speak up for me.

Atmosphere doesn't cut off, it just gets thinner and thinner. There is enough air resistance at 450km, such that anything in LEO needs regular boosting. Larger surface area, more frequent boosting. Shuttle is important to ISS because it can boost it to a higher orbit. Otherwise you have to do this with Progress vehicles and they have limited amount of fuel on board so only so many times you can perform it. Anything that's in LEO is bound to crash back to earth, eventually. GEO is stable, they will loose their perfect orbit around the equator sometime int he future but they will not fall back to earth for thousands of years.
before someone corrects me, the third sentence of the second paragraph is misleading. It should read the effect of the drag will depend on the total mass of the debris. Drag will create a force and the acceleration on the object will depend on the mass of the object.
I don't know. I live in England but I never drove a British car. I drove a Renault (french), a Fiat (italian), a Mazda (japanese), a Nissan (japanese) and now I'm driving a Volvo (Swedish). None leaked oil. In 12 years I never got a single point on my license.
:-) Don't think so. It's the americans who run the ISS. Russians only get paid as taxi drivers and delivery man.:-) Russians' involvement is all a nice PR show. They can hardly build two soyuz crafts and a couple of Progress every year. That's not enough for a serious space program (but still, compared to the rest of the world, they still have the best and safest space program in the world).
When I was in the university we had this IBM3090 mainframe beast... And at home I had this 386 running OS/2... And on both I could run and develop the REXX Mud we were writing. That's cool stuff man. These days it's much easier with lots of scripting languages available but REXX really ruled in 90s. Now I use Java, which is much better but I still remember those days fondly.
The best justification for OS/2 was it was a brilliant multitasking operating system and poor BBS sysops like I were happy with it because it really worked. Not like that Win3.1 crap or that stupid NT thing which you needed LOTS RAM. I ran OS/2 with 8MB and it was a dream. If only my win2K workstation would run as fast as that old 386 (later 486) with OS/2.
I ran Maximus BBS for years and it was fun fun fun! Sysops are sad losers which can distinguish all sorts of V protocols by the sound of the modems. The real sad ones can whistle a 1200 baud link (I managed an 300 baud one consistantly but never managed to do 1200 baud).
There are many aspects. Earth is not a perfect sphere. This means there are many gravitational variations. This means along the path any piece of debris will be pulled towards earth with a different acceleration. This means the orbit will not be a perfect mathematical equation. This means a piece may move wrt the original location.
The second is air resistance in that height. As anyone knows, air resistance depends on the surface area. The drag will depend on the total mass of the debris. This means relatively space station and the debris eventually will have relative speed difference and a piece of debris with enough m/s can have enough energy to pierce the hull, which is a simple aluminum tin, not a 10 cm solid sheet of steel. On the other hand the ISS hull is not a tin can, it is layered with lots of equipment and cables. This also means they will have trouble locating the hole. They had the same problem with Spectre module in Mir, whatever they did, they couldn't locate the hole from inside and outside. That's also why they had a pressure loss scare a couple of months ago. They just couldn't find if there was a hole or not.
Any news is good PR. NASA will make to the headlines again, it will be mentioned and probably the positive spin about Bush's Mars program and ISS' place in it will be mentioned again and again. I think they're allright, they will say it is common, the piece is unimportant etc.
Something people don't understand is once you've been up there, most probably you won't go back again unless you are lucky/have a good relationship with management. Most people go to space for at most three times, only one has been there for seven times. Russians have a smaller cosmonaut team. This means they can actually have people experienced with the actual thing. Two years of training and two weeks on the shuttle is nothing compared to the russian cosmonauts' flying time experience.
As a result, when you are in the station, you won't be able to find anything. This was a major issue with Mir and Skylab, probably it was with Salyuts as well. No one stows the experiment equipment once they use it, just straps it into a convenient location. If you do a space walk, the chances are it will be your first time outside of the space station and you will get lost, won't find what you are looking for and won't remember the training session you had a year ago in a boring, hot Texan day.
I think it would be a godsend to American space program. They would just cancel it and that would be it. No more budget black holes. Back to fixing Hubble and everything that really matters gets funding. It might be a conpiracy. These are not the bolts you are looking for.
Interesting note, current ISS commander Michael Foayle was onboard Mir when they had the accident with the Progress vehicle. This guy seems to be really unlucky. It was Mir that was falling apart around him, this time it is ISS.
I am not military. Bombing without any regard to civilians, targets and soldiers is a crime. USA is the master of this since 1942. Vietnam, Munich, Dresden, lately Afghanistan clearly shows how effective this is for killing people but not necessarily winning a war.
I didn't say it was an arbitrary unit... Nautical miles per hour was measured by counting knots on a piece of rope as it dragged behind... What's strange with that? Haven't you ever read Jules Verne? Even in one of his books this fact gets a reference. The young "captain" accidentally loses is parakete(sp?) and his ability to measure his speed is lost. Then some evil guy puts a magnet under his navigational compass and he ends up in Africa instead of America. More adventure follows. It's a shame I can't remember the book's name.:-) Last I read this book, it was at least 20 years ago.:-)
Define "these kinds of weapons". I suspect an F-18, or even a cheap F-16 won't be available to anyone but many italian, british and russian makes are. In many cases it's no use to have a strike aircraft. Mortars, RPGs and machine guns are more useful. Bombing gerilla forces is not effective, sending some soldiers to wipe them is. Former is for propoganda/morale reasons, the latter is a solution to the problem. Of course carpet bombing (as the USofA does) is not the same thing. Their blanket and/or precise use of air power is different than any other country's implementation.
Don't know. because it is a fluid and you are measuring a speed that is relative to the fluid you are in? Measuring something trailing behind is easier than measuring speed relative to an object on the ground.
