The basic mission sequence to achieve the President's goal is clear: begin with Space Station Freedom in the 1990's, return to the Moon to stay early in the Next century, and then journey to Mars. Five reference approaches are modeled building on past programs and recent studies to reflect wide-ranging strategies that incorporate varied program objectives, schedules, technologies, and resource availabilities. The reference approaches are (1) balance and speed; (2) the earliest possible landing on Mars; (3) reduce logistics from Earth; (4) schedule adapted to Space Station Freedom; and (5) reduced scales. The study and programmatic assessment have shown that the Human Exploration Initiative is indeed a feasible approach to achieving the President's goals. Several reasonable alternatives exist, but a long-range commitment and significant resources will be required. However, the value of the program and the benefits to the Nation are immeasurable.

During 1988, the National Research Council's Space Science Board reorganized itself to more effectively address NASA's advisory needs. The Board's scope was broadened: it was renamed the Space Studies Board and, among other new initiatives, the Committee on Human Exploration was created. The new committee was intended to focus on the scientific aspects of human exploration programs, rather than engineering issues. Their research led to three reports: Scientific Prerequisites for the Human Exploration of Space published in 1993, Scientific Opportunities in the Human Exploration of Space published in 1994, and Science Management in the Human Exploration of Space published in 1997. These three reports are collected and reprinted in this volume in their entirety as originally published.

Personnel representing several NASA field centers have formulated a "Reference Mission" addressing human exploration of Mars. Summarizes their work and describes a plan for the first human missions to Mars, using approaches that are technically feasible, have reasonable risks, and have relatively low costs. The architecture for the Mars Reference Mission builds on previous work of the Synthesis Group (1991) and Zubrin's (1991) concepts for the use of propellants derived from the Martian Atmosphere. In defining the Reference Mission, choices have been made. The rationale for each choice is documented; however, unanticipated technology advances or political decisions might change the choices in the future.
