The United States has publicly funded its human spaceflight program
on a continuous basis for more than a half-century, through three
wars and a half-dozen recessions, from the early Mercury and Gemini
suborbital and Earth orbital missions, to the lunar landings, and
thence to the first reusable winged crewed spaceplane that the
United States operated for three decades. Today the United States
is the major partner in a massive orbital facility - the
International Space Station - that is becoming the focal point for
the first tentative steps in commercial cargo and crewed orbital
space flights. And yet, the long-term future of human spaceflight
beyond this project is unclear. Pronouncements by multiple
presidents of bold new ventures by Americans to the Moon, to Mars,
and to an asteroid in its native orbit, have not been matched by
the same commitment that accompanied President Kennedy\'s now
fabled 1961 speech-namely, the substantial increase in NASA funding
needed to make it happen. Are we still committed to advancing human
spaceflight? What should a long-term goal be, and what does the
United States need to do to achieve it? Pathways to Exploration
explores the case for advancing this endeavor, drawing on the
history of rationales for human spaceflight, examining the
attitudes of stakeholders and the public, and carefully assessing
the technical and fiscal realities. This report recommends
maintaining the long-term focus on Mars as the horizon goal for
human space exploration. With this goal in mind, the report
considers funding levels necessary to maintain a robust tempo of
execution, current research and exploration projects and the
time/resources needed to continue them, and international
cooperation that could contribute to the achievement of spaceflight
to Mars. According to Pathways to Exploration, a successful U.S.
program would require sustained national commitment and a budget
that increases by more than the rate of inflation. In reviving a
U.S. human exploration program capable of answering the enduring
questions about humanity's destiny beyond our tiny blue planet, the
nation will need to grapple with the attitudinal and fiscal
realities of the nation today while staying true to a small but
crucial set of fundamental principles for the conduct of
exploration of the endless frontier. The recommendations of
Pathways to Exploration provide a clear map toward a human
spaceflight program that inspires students and citizens by
furthering human exploration and discovery, while taking into
account the long-term commitment necessary to achieve this goal.
