Abstract: | On the basis of numerical experiments, we have shown the principal possibility of long (more than 1 month) and extremely long
(more than 1 year) orbit lifetime of technogenic microparticles with radii from 1 to 100 μm injected into the near-Earth space
in highly elliptical orbits with low perigee, including the case of an orbit with parameters corresponding to the orbital
parameters of the Molniya satellite. Calculations are performed taking into account the perturbing effect on the orbital microparticle motion in the
near-Earth space of gravitational perturbation caused by the Earth’s polar oblateness, the solar pressure force (calculated
using methods of the Mie theory), and the drag force of neutral component of the background gas under conditions of low, medium,
and high levels of solar and geomagnetic activities. |
