to rescue what exactly?

Chinese or Russian satellite “rescuer”.

I won't be surprised if a military satellite of any state capable of launching military satellites will self-destruct if taken away forcibly from the designated orbit. A simple acceleration test would suffice.

I also won't be surprised if when self-destructing, such satellite will try to deliberately damage everything in its close vicinity.

Cool a mini space shuttle that is still flying around for testing stuff. Any chance it has seats and can be used for rescues?

Wait for Dream Chaser, first unmanned orbital flight planned for 2020. That one looks more promising, at least it's bigger and originally planned to be used manned.

I don’t think they make boobytrapped satellites that explode, but they may remotely activate a self-destruct process which renders abduction pointless.

If they exploded it wouldn’t it create more problems than it solves in terms of more flying debris they have to track as well as friendlies in the same orbital path? (Like when Iridium 33 crashed into a defunct soviet satellite.)

Obvious missions for a long-mission mobile shuttle like this include

* intercepting and deorbiting space junk

* fixing friendly or sabotaging unfriendly operational satellites

* future weapons platform for offense or defense (say intercepting ground-launched sat-killing missiles)

* on-demand surveillance (with ordinary spy satellites you have to wait until your orbit is in the right spot, adversaries will know when your satellites are above them and adjust their activities to avoid surveillance)

* more routine human activities in LEO (spacecraft assembly, staging for higher orbits or interplanetary activities, shuttling between stations in LEO)

* Netflix and chill with our alien overlords

* Prep for mining activities further out

Literally all of these could occur more cheaply without deorbiting the spacecraft.

Space isn't like a highway where you can move from A to B at minimal expense. Switching orbits, both orbit heights but mainly orbit inclinations, comes at a very high delta-V expense and therefore propellant expense, which this craft simply doesn't have the volume to hold.

This cannot shuttle between LEO stations and switch orbits to imitate multiple observation sats unless those sats and stations are very close in terms of orbits.

people who haven't played kerbal space program (with mechjeb for data) usually don't fully understand how expensive, in terms of delta V, a large inclination change maneuver is.
