This second stage includes a capture phase, an aerobraking campaign, and the science orbit insertion. The near-Mars dynamic model considers the zonal harmonics and atmospheric drag. Three reference optimizations are conducted and compared with the proposed method. The first reference is separated optimization that optimizes the heliocentric transfer and Mars arrival trajectory sequentially. The second is the fixed spacecraft design method without optimizing the spacecraft hardware parameter but using a predefined value while optimizing the same problem.

The other two rely on experimental and numerical results and take into account the impactor-to-tether relative velocity. As a result, the severing rate formula is a triple integral involving the differential flux of debris as a function of the debris size, velocity and impact angle. In order to evaluate the severing rate, a database of the differential flux for different orbit altitudes and inclinations was constructed by using Master 8.03. After implementing and verifying a numerical code, several parametric analyses were conducted to understand the effect of the three ballistic limit equations and the impoverished state of the space debris population on the severing rate. As compared with the simple 1/3 ballistic limit equation, the severing rates found with the two experimental ballistic limit equations are a factor of two lower (or more, depending on the orbit) for the same debris flux and similar among them.
