DOI: 10.1016/j.ast.2020.106240
Abstract: Abstract The probabilistic uncertainties in Mars atmospheric entry degrade the entry guidance performance. The propagation law of high-dimensional uncertainty during Mars atmospheric entry is still an open problem that should be investigated. The current work… read more here.

DOI: 10.1016/j.matchar.2017.02.016
Abstract: Abstract In order to mitigate debris in orbit and to avoid dramatic collisions on Earth after atmospheric re-entry at its end-of-life, the spacecraft missions have to take into account the influence of atmospheric re-entry conditions… read more here.
