All very interesting but not my problem.
We need to get there first.
We need to reduce that cost don't you think?
So we need to reduce the cost of the vehicle we need to get there.
Mass production of rockets is the real solution we are looking for that
makes all these things achievable.
We have trains, planes and automobiles. Lot's of them! We need many many
more rockets to make space a reality.
So we are back again to the infrastructure problem.
We have big ships that move supplies we have big trains that move
supplies we have big trucks that move supplies. We have cars that move
us around and even motorcycles and bicycles.
If we go into space at a rate that will produce results how is that
going to effect the earth? If we launch enough rockets to fuel the space
revolution?
Are we going to leave the planet or are we just toying with the idea of
leaving the planet?
I find these are the real questions we need to answer first.
If we stay here we die I'm pretty sure and that tipping point is
approaching more rapidly every day.
One day perhaps sooner rather than later it may be too late.
Either that or we collapse in on ourselves and start over and it will
then be quite a long time before the human race can try again. If we
survive.
Maybe I'm wrong but I get a sick feeling we need to go. NOW
So hurry up! lol
Thought is the path but emotion is the vehicle that gets you there.

Henry,
That's definitely a possibility, but I think there are probably better
approaches. For our planned servicing/deorbit services, we've been working
on grappling fixtures that can enable a wide range of grappling methods to
safely interface with the target. That doesn't do anything about
preexisting spacecraft, but can make interfacing with future spacecraft
dramatically cheaper and easier. For grappling with pre-existing spacecraft
I'd still prefer mechanical grasping of known features (marman clamps,
solar array booms, etc) to the kind of underactuated truss grasping we did
for the ARM boulder grabber, but I guess that could be an option in some
corner cases.

If the only problem you're trying to solve is deorbit, then yes there's a
broader class of solutions. But if you want to enable intact servicing as
well, you need something capable of grappling a target...
And if you want examples of how you might grapple to an uncooperative and
possibly tumbling target, just look at some of the design concepts for the
ARM mini-asteroid/boulder grabber that people came up with over the year or
two in which ARM was a going project. Not a trivial problem but not an
insuperable one either, especially if you accept that the grabber might be
a one-shot expendable device.
