Manned Flight to the Nearer Planets

Abstract

We need a long-range goal for space exploration which is well defined and highly visible. On a 10 year timescale, a manned flyby/orbiter of the planet Mars would give important scientific returns, at a relatively low incremental cost, using building blocks developed in other programs. This project would also lead to major advances in technology, keep open the option of future manned landings, and maintain popular support of the space program. A specific scientific objective of highest interest is the detailed examination of Photos and Deimos, the natural satellites of Mars. They may be captured asteroids, or they may even be remnant samples of the primeval planetesimals which performed the planets of the solar system.
