the Cd of 2 would explain... all of it, pretty much. I have not seen that figure before, but it isn't my area,either...
I tried to find the atmospheric data on when exactly it stops being an issue... but it seems to vary due to space weather, and i couldn't find a decent answer... at some point above LEO and below geosync, i would imagine... somewhere in the 800-1000 Km attitude, if i took a wild guess. Any more precice numbers?
i wasn't intending to discredit anyone, far from it... i was just a little punchy myself, just got home from a 3 hour chem class... surely you understand.. {wink}
avition i can qualify myself on far better then spacefaring, having accually done it... aircraft opperate on t=d and l=g... not sure how best to express it on slashdot, but when t=thurst is removed, g=gravity becomes the primary locomotor... if you held altitude until a stall set in, lift is removed, and only drag and gravity is left.. a properly rigged craft would resume generating lift as soon as the speed built up. I assume that's what you meant to say;)
kinetic energy is correct, but not the most accurate term to use for forward flight.. a plane can be moving at a high rate of speed, yet is not generating lift, or very little... spins, and perticularly sprials demonstrate this, as would a 9.8 m/s/s descent. best term i know of to use is simply airflow over the lifting surfaces.
err... I did. ISS is affected by atmospheric drag, but minimally.. according to nasa, the atmosphere "offically" extends to 600 KM/372 Mi, while the ISS's orbit is between 351 and 360 KM... Hrmm...
This is a graph showing the orbits of the ISS over a year, with it's reboosts.. Granted, it does need frequent orbital boosting, but the question remains, will a shuttle cause adverse drag? I think, considering all the times a shuttle has been there many times before, if it were detramental, they might have noticed before now.
I admit i was mistaken, but the ions per m3 could probably be counted on one hand... drag is still not the biggest issue, i think.
to for once be on topic... in soviet russia, Buran is the last figging thing to be blown into orbit before the USSR collapsed, and they run out o' el dinero.
because... the shuttle's OMS system total delta V is... lacking... for such opperations. quick googling shows the delta V for the shuttle OMS is ~700M/s... in other words, after the main engines stop burning, it has the ability to add (or take away) only 700M/s speed to its energy. Of this 700 m/s, it has to circularize it's orbit (the main engines do not complete orbit entry, so the ET can reenter properly), change its orbit to intercept the ISS, and then burn retrograde to slow down to reenter the aphmisphere.
it just can't do it, really... not effectivly, anyway.
Also, the GP is... Misinformed. I would look up the data on main propulsion motors for LEO sattelites, if i were him/her/them/... If you can find them.
Things do not need active propulsion to maintain orbit. Unrelated physically, but of the same ilk, Airplanes do NOT fall out of the sky if the engine stops. (interestingly, neither do helicopters,:D)
Mercury... didn't one of them sink on splashdown? I call that a bad day, if i'm riding it... 1 out of 7 error, there.
Gemini had a GATV go nuts and spin one like a tilt-a-whirl... also not good... that's one out of.../me looks up... 10 gemini's
Apollo; More interesting... Far higher capibilty/risk vehicle then anything before or since. Apollos 1,7-17,SkylabCSM 1-3, and the ASTP were all manned, for a total of 16 missions, with two failures out of those. (Add several more launches for unmanned saturn boosters, which is (if i am correct) the only booster to never have a disabling failure.)
I found the numbers.. someone else can do the math, it's late;-)
I think if they knew that the O ring was going to fail and puncture the main fuel tank, they would have done something...
foam, on the other hand is evil; ever tried to get static-y foam off of a package UPS/FEDEX/USPS/ETC sent you? IN-FRICKING-POSSIBLE. Hence, foam = E-VIL.
I thought this new video service was not like the image search... instead of indexing video files (not that that would be a bad thing), this is a google service like blogger (attached to blogger somehow?) where they will host the things people upload...
wondering somewhat seriously, what, if any, useful data can be pulled off the average prono from text to speech... Will this usher in the concept of the stars describing the upcoming scene? Maybe a narrator... Two birds/one stone, that way.. Easily indexed XXX and accessible to the visually impaired...
For everyone who thinks Camino is speedy versus Firefox and Safari, you should search the mozillazine forums for arch optimized nightlys of it... The closest comparation I can make is when the roadrunner goes "Beep-Beep" and leaves the coyote in the dust.:P
Both are spanish. Literally, El Camino means "The Road", but like a lot of spanish words, it changes in context, and for the browser, Camino refers to "Pathfinder", which fits in nicely with the Navagator, the Explorer, and (sort of) the Conqueror and The Big F***in Lizard.(?)

Good sir, I do believe a rimshot is in order here... For it seems you've been played like a violin.
any links on NON rooted dos?
nahhh... real trick is, if i'm the father, being only 19... :-D
um... i... have to... be right back... yea,that's it...
argh, mixing attitude and altitude again... [sign that sleep is becoming a requirment] ;-)

I thought Linus edited bzImage with Vi... (or was it EMACS?)
if they fixed so that it's impossible to hack a box, and no one told me... Heads. Will. Roll.
I wish tiger would run on my intel i830 mobo too... think it needs more then 64M ram, maybe?
above assumption erroreous?

see orbitersim.com and see if you can manage it
We have this: It's called a flipbook. Now, if only HP would make a 24 page per second printer...
