Partial answer to
Are there plans to modify the ISS prior to de-orbit to reduce fragment size or number.?
No. Deorbit plans focus on configuring the ISS for maximum trajectory and debris footprint predictability, not debris fragment size minimization. The type of debris enters into the footprint prediction as a range of mass-to-area ratios. Since the ...
Yes! Unintentionally! On 29 July 2021 at 11:34 am Houston time, after having docked earlier at 8:30 am CT (13:30 UTC), the Nauka Multipurpose Laboratory Module (Upgrade) unexpectedly fired its movement thrusters, and did so for a good 45 minutes.
Well, the answer was well written for another question already, by OP:
this answer to Did the ISS just turn ...
Your question assumes that legs aren't used on EVAs, however legs are actually important for leverage. The first EVAs did not go well, astronauts were unable to complete tasks partly because they couldn't exert enough force. The assumption was that legs would be useless, but part of the solution was to anchor the legs on different parts of the spacecraft ...
No way to make the booster go into orbit unless you remove starship and still make it fly correctly, you would also lose alot of fuel during launch. A better option is just have a very large starship with no flaps or heat shield and use that as a fuel depot. Wouldn't have to change the design of the booster then.
Ooh, this is old.
I do feel the answers need a little addition though:
Why would NASA not choose to go with their conceptual design when building the ISS,
See below, but TL;DR: Russia coming on board and Mir-Shuttle docking experience killed off the design.
and how would it have worked?
See below. NASA patented a concept of its operation.
The two ...
