“…The higher the /, the more difficult the mission. Mascy, Dugan, and Pitts (1968) terms of use, available at https://www.cambridge.org/core/terms. https://doi.org/10.1017/S0252921100089363 have shown that the systematic mapping of this energy parameter provides a convenient technique for determining the best launch and arrival dates and the effect of varying trip times and stay times.…”

Of the many asteroids that are cataloged, selection of a target planetoid was narrowed to the Mars-crossing asteroids. The main belt and Trojan asteroids are much farther away and require longer voyage times and propulsive energy to accomplish sample returns. Within the Mars-crossing group, those asteroids were surveyed that have orbits inclined less than 15°, perihelia within 0.2 AU of Earth’s orbit (and therefore require less propulsive energy), and diameters greater than 1 km (to assist terminal observation and rendezvous). Eros was chosen as representative of this class.
