:: ... plus perhaps some hanging hammock type return capacity..

: Fred J. McCall
: Some WHAT? You really don't have a clue about this stuff, do you?

It's a bit difficult to even tell what he's confused about, so that
something described as a "hammock" would help. Let alone "hammock
type return".

Of course, for somebody who thinks nobody at the controls of the ISS
for a few hours will cause it to plummet into the atmosphere or maybe
swerve off course into the next galaxy or something (what*ever* he
thought would happen; other than "falling" modules it wasn't clear),
I suppose a "hammock type return" is par for the course.

On the other hand, give him a break. For somebody who apparently doesn't
know what an orbit is or what freefall is, what can you expect?

One can also google and get hits on "space hammocks".
Maybe that confused him.

the problem isnt no one in control for a few hours......

its no one in control for days weeks or months...

imagine a serious soyuz problem that grounds the program for 6 months....

at some point the soyuz at the station will age and must be sent home, since soyuz are only good for 6 months in orbit.

since soyuz are generally replaced near the end of their in orbit life crews must be returned...

and could leave the station unmanned for lack of emergency escape.

the obvious fix is keeping at least one musk unmanned capsule at station as a backup emergency escape. this would be a good idea even if soyuz didnt have problems.

a debris hit on the station is always possible and might disable a soyuz.

the more back ups for a bad day the better....

with just enough soyuz at station to evacuate the crew a station debris hit could damage the station while taking out the soyuz escape capsule

the ability to have crew remain at station without concern for soyuz aging out of their life expectancy should be of concern to everyone....

heck a soyuz that fails at station for any reasons potentally leaves 3 ISS crew stuck with no way home....

and the fact the russian program has had so many different failures is a bad sign.

the problem isnt a one off issue it effects every part of russias space program

: aging out of their life expectancy

Of course, near as I can tell, you're saying that the shelf life of
them soyuzen is no longer than they could *operate* in space.
Unless you want to cite different?

once launched a soyuz is only good for 6 months at station.

it would of been a good idea to upgrade a couple soyuz to be a permanent part of ISS untill used, or at least a couple years life expectancy at station..'

with longer crew rotations and the increasing amount of in orbit debris some backup would be a good addition to ISS
