Recent events have put a fair amount of debris in potential collision
with ISS and I assume a bunch of LEO satellites. It isn't the first
time and likely not the last.
At the technical perspective, what concepts/technolopgies could
pontentially be developped to make a vaccum cleaner for space?
Say you can easiuly lauch a ship in same orbit as the debris field and
it can sneak up behind it. Is the concept of using a laser to vaproize pieces of metal real or just science fiction? If you "laser" a piece of depris, does it just become small pellets of aliminium which then become bullets that penetrate ISS or other satellites? Or would it render the aluminium harmless ?
It is possible to recreate re-entry conditions that destroy the pieces?
Or is physically capturing the pieces, put them in a big bucket and de-orbiting the bucket the only way?
Could one launch retrograde in that orbit and spread air in the orbital
path at that altitude such that when the debris hit that air (which
woudld be going at orbital sped in opposite direction) would slow down
the debris and/or burn it up? (causing both debris and air to drop
down).
I am curious to see what science would come up with should there be a challenge of cleaning space debris equal to landing a man on the moon
and returning him safely before the end of the decade.

The debris field tends to spread out, and it's not in a single orbit,
because the initial destruction imparted different velocities to the
bits, in all directions.

Yes. But all of the pieces that stay in orbit (some can re-enter
immediately, others may escape) should return to the point of impact.
At least initially. As you said, the field will spread out.
