Examination of a Practical Aerobraking Guidance Algorithm
Steven W. Evans,Greg A. Dukeman +1 more
TL;DR: In this paper, a real-time guidance algorithm for aerobraking vehicles that minimizes the post-aeropass Delta V requirements for orbit insertion while nearly minimizing the maximum heating rate and the maximum structural loads is presented.
A comparison of NASA, DoD, and hydrocode ballistic limit predictions for spherical and non-spherical shapes versus dual- and single-wall targets, and their effects on orbital debris penetration risk
TL;DR: In this article, the authors compared the impact probability of a single-wall and a dual-wall shield for velocities up to 15 km/sec with the results of the DoD predictions for a sphere and a cube.

Bounding the risk of crew loss following orbital debris penetration of the international space station at assembly stages 1J and 1E
TL;DR: The Manned Spacecraft Crew Survivability code is used to evaluate the risk to crew of penetrations of pressurized modules at two assembly stages: after Flight 1J, when the pressurized elements of Kibo, the Japanese Experiment Module, are present, and after flight 1E, whenThe European Columbus Module is present.
