I know I have asked this before, but how would they do this ? Fire a
progress from 400km altitude ?
Could one Progress do it, or woul it require multiple trips?
Can they let orbit decay , perhaps using solar array as sails to
increase drag, and then send a progress to do controlled burn to target splashdown?
I take it Zarya's engines are no longer usable? Or could they
theoretically still be used?
Conceptually, could a Dragon do the job, then detach quickly, and fire
its engines to regain some speed so it splashes down near the shore of Malibu Beach where female lifeguards could come and greet the crew?
or would the complex already be too close to atmosphere at end of
de-orbit burn to allow a Dragon to significantly extend its flight to
reach west coast of USA ?

Is this just another "funding until" step with life extended further at
some later point, or a true terminal decision that defined a "hard" end
of the line for iSS in 2031 ?
