But, if you were to put your "little retro rockets" on BOTH SIDES of the space ship, you could blow on the asteroid with the rockets on one side to deflect it and keep the ship on station with the rockets on the other side. That might work.
Or, if you could use the other idea I've seen somewhere to hit it with a laser from a distance, and make the laser powerful enough, you might be able to knock chunks off it and get the same action and reaction to cause a deflection. If this could work the big advantage is you don't have to go chasing after the damn thing just shoot straight.

Last year my wife was diagnosed with Motor Neurone Disease, and in March I found myself having to have that awful conversation with the hospital registrar, to tell her that my wife had suffered enough and that she was to be allowed to pass away with whatever dignity she still had.
Along with her family I then had to sit with her, talk to her, hold her hand and try to comfort her while they took away the ventilator and pumped her full of morphine.
This horrible disease takes away a person's ability to control the muscles of their body yet leaves the brain and consciousness completely intact, so she knew exactly what was about to happen and I have worried for months about what the hell she must have been thinking while we were watching over her as she died.
Knowing from your personal experience that the morphine takes away the fear of death comforts me more than you can know.
I am now in a similar situation to you, out of work but trying to get back on track and find a new partner to share happy times with.
