- Abstract
- The effect, on the growth of the space debris population, of the mitigation measures
proposed at the international level, is investigated.
We consider scenarios involving only the de-orbiting of satellites
at the end-of-life and mixed scenarios involving both the de-orbiting and
the re-orbiting in different super-LEO graveyard zones
(above 1700, 2000 or 2500 km).
Then the mitigation measures are analyzed in terms of the Delta V
required to accomplish the de-orbiting or re-orbiting maneuvers,
in a realistic traffic scenario.
The use of delayed reentry disposal orbits, e.g. with 25-years
residual lifetime, allows, on average, a saving of ~30 %
on the amount of propellant.
The use of the graveyard regions further reduces the propellant
needs, while introducing possible problems due to the accumulation of a
large number of objects in restricted regions of space.
In particular, a collision risk analysis shows that the use of the lowest
proposed graveyard zone, above 1700 km, gives way
to a dramatic increase in the number of catastrophic collisions in
the graveyard region, in the next decades.
On the other hand, it has been shown that the de-orbiting of old spacecraft
on elliptical disposal orbits with residual lifetime around 25 -- 50 years
significantly increase the collision risk for the International Space Station.
A mixed strategy, involving de-orbiting to 25-year residual lifetime disposal orbits and
re-orbiting to a storage zone above 2000 km,
appears to be the best compromise between the debris
mitigation problem and the practical operational issues
(i.e. in terms of Delta V required to accomplish the
maneuvers). (literal)
