OT What is the big deal about Hubble danger? The news keeps talking about how dangerous the Hubble telescope repair is, and NASA set up a second shuttle on the launch pad right after the first one took off.
This is the third repair mission to Hubble in in the past 19 years. Weren't the other two the same as this one, just the Space Shuttle and nothing else?

I think they are just dealing with the possibility that something could go wrong with Atlantis and they would not have any way to go get them. Bear in mind, the shuttle has demonstrated a 40% failure rate. 2 out of the 5 that went into space, crashed and that is slightly less than 1% of the total number of flights. Half of those crashes could have been prevented if we had a way to get to the vehicle in orbit. That is why they have one on the pad, standing by.

Assuming they would have sent it up. If you will remember on Challenger, the muckety mucks decided there wasn't enough of a concern to even merit a telescopic once over from earth. Challenger would have gone ka-boom even if a standby had been available. This is pretty much bureaucratic CYA and preparing the populace for problems ahead of time. Then, if nothing happens, they can pat themselves on the back about what a great planning job and it looks that much more impressive to The Great UnWashed. If something bad happens, then the populace was essentially trained to expect, the hope being that only lower level heads will roll.

Okay, so it was Columbia. So much for writing these things off the top of my head.

On Fri, 15 May 2009 15:23:58 -0400, against all advice, something compelled snipped-for-privacy@aol.com, to say:

They're worried that a bit of space junk will hit them, and they'll need a new ride home.

I like how the newsmedia is hyping this fact. I mean, the HST has been in orbit for 19 years and hasnt been hit by any debris yet.
Here's a quote from an article today:
"That wasn't the only unnerving thing about this mission.
Space is particularly littered in this 350-mile-high orbit, and Atlantis and its crew face a greater risk of being slammed by a piece of junk. As a precaution, NASA has a rescue shuttle on standby, ready to launch in just three days if necessary."
So why would they be slammed with space junk during this 5 day mission, if the HST hasnt been hit in 19 years?

And even if it was only 13 years at one altitude and 6 at the higher, right you are.

Sez who? It's probably been hit by a lot of space junk,but not damaged enough to affect it.They install protective blankets and shields to stop the smaller particles.
BUT,the recent Red Chinese ASAT test left a lot of bigger,more dangerous debris.

Who says it hasn't been hit? what do YOU know about it? Note one of the shuttles was hit by a paint chip that damaged it's windshield.Damaged,but not critically.
Why is it the Earth has only been struck by a Dinosaur Killer 65 million years ago,and not more recently?

ALL of the crashes could have been prevented if NASA had not become so corrupt, cost-oriented, and over-confident that they allowed Challenger to fly DESPITE the engineers' pointing out that weather was too cold. O-Ring. Case Closed. BTW does anybody remember seeing the late, sainted, Richard Feynman blowing away that whole investigative panels of fat-assed idiots by doing his little ice-water, O-ring demo on TV? That was WAY kewl!
Columbia, same deal: lazy, over-confident; flying that ancient junker w/o worrying about foam panels detaching; has happened before; past shuttles flew OK, so what, me worry?
Price paid for both disasters: Lost some of the finest human beings to walk the earth, or sail the skies. Plus the enormous wasted training costs). Indescribable grief to their families. First Israeli astronaut, loved by all, died in that hell. Take a look at the ISRAELI documentary; VERY different from the kiss-up US documentary(ies) on that loss.

Columbia got everybody thinking about what happens if the Shuttle is damaged and can't return home.
All the other missions are to the ISS, so the astronauts can remain there if the Shuttle is damaged. But, there's not enough fuel to get to the Hubble and the ISS, so taking refure there is not an option for this mission.
In short, the risk has always been there, but post-Columbia, there have to be contingencies in place to handle it.

Your use of the term "Red Chinese" is quaint, and a bit anachronistic. Are you still living in the dim anti-Communist past? Just what other Chinese are you concerned about us confusing the Chinese with? The Taiwanese?

the hubble danger is largely about...........
even a tiny piece of space debris like a paint chip hitting a astronaut in a space suit. moving at 17,000 miles per hour, even a paint chip could kill not only a crew member in a space suit, but take out the entire shuttle.
it could be left depressurized, out of control orbiting till it falls back to earth like skylab did.
a major hazard, since the shuttle would break up scattering debris as it tumbles and re enters.
the worst would be a stranded depressurized shuttle still attached to hubble. this high drag would bring them both down quickly, and given their large size and large components, like hubbles mirror,
no doubt some would be hit on the ground, or the mass panic casulaties..
all these risks are beyond a shuttle getting stuck in orbit somehow.........
espically a debris hit to a thermal protection part just before re entry

Low earth orbit could be made unusable if too many collisions create too much more space debris.......
They tend to spread and collide with more stuff creating many more debris

I believe that debris is in a different orbital plane and not directly threatening the shuttle ops.

Dunno. I think the earlier repairs where made at lower orbit? Then the HST was moved out to 350 miles about earth. It's be said there is a larger, more dangerous debris field out there. Has the Space Shuttles ever been that far out?
