Why the NASA approach will likely fail to send humans to Mars prior to c. 2080, mission is taken into account, including transit to Mars, surface stay, and return, the differences between Mars missions and lunar missions are very significant. There are also significant differences in Δν requirements for various transits, although these can be partly mitigated by aero-assist technologies at Mars.作者: Benign 時間: 2025-3-24 22:54

utilization of indigenous resources,n. By utilizing indigenous resources, the amount of material that must be brought from Earth is reduced, thus reducing IMLEO. ISRU has the greatest value when the ratio: . is large.
