Space Policy Experts Discuss Goals for Human
Spaceflight Program
It is not only the Bush Administration that has
wrestled with the question of where the nation's human
spaceflight program should be headed. Congress has
held hearings on this question, and several months
prior to President Bush's proposal to return to the
Moon and then send humans to Mars, a group of experts
in space policy held a workshop to air their views.
Although the workshop was not intended to develop
consensus recommendations, there were a number of
comments that received broad agreement: Since the end
of the Apollo program and the Cold War, the role of
the U.S. human spaceflight program has been uncertain;
the program needs a clear long-term goal developed by
a national dialogue, with a progression of smaller
missions leading toward that goal; it needs to use
NASA's space and Earth science programs as successful
models and must move beyond competition between human
and robotic exploration by taking advantage of the
benefits of both; sending humans to Mars is a likely
long-term goal; and fundamental changes will be
required on NASA's part to achieve such a goal.
The November 12-13 workshop was held jointly by the
National Research Council's Space Studies Board and
its Aeronautics and Space Engineering Board, with
other invited guests. A prepublication version of a
report on the workshop, "Issues and Opportunities
Regarding the U.S. Space Program," breaks out seven
themes around which there seemed to be general
agreement among participants:
THEME 1. Successful Space and Earth Science Programs:
According to the report, the U.S. space and Earth
science programs are generally considered productive
and successful, and benefit from the "constructive
tension" between NASA, which implements the program,
and independent stakeholders - members of the science
community - who set and periodically revisit the
program's goals. Numerous independent missions of
varying sizes enable the programs' continued progress,
momentum, and political support. Many workshop
participants felt that the human spaceflight program
could benefit by applying "lessons learned" from
NASA's science programs. In particular, it was noted
that the human spaceflight program lacks independent
stakeholders.
THEME 2. A Clear Goal for Human Spaceflight: There
was consensus among workshop participants that the
human spaceflight program lacks - and needs - a clear
long-term goal. "Without such a long-range goal," the
report states, "the human spaceflight program's reason
for being is hard to articulate," as is the
justification for components such as the space station
and shuttle. The suggestion was made that, with the
end of the Cold War, there is no longer a need to
demonstrate U.S. technical prowess in space, but a
long-term human spaceflight goal could help the U. S.
demonstrate leadership and goodwill in cooperation
with other nations. It was thought that the goal
would be determined through a national and
international dialogue.
THEME 3. Exploration as the Goal for Human
paceflight: Many participants believed that the
primary goal of the human spaceflight program should
be exploration, in order to satisfy a basic human
drive and to contribute to the acquisition of new
knowledge. "Exploration is a legitimate form of
science, if properly conducted," one of the
participants stated. Others commented that human
explorers can take advantage of "unanticipated
learning" opportunities for learning in a way that
robots cannot, and humans can communicate to others
what it is like to experience outer space. Some
participants felt that human exploration of Mars was
an appropriate long-term goal.
THEME 4. Exploration as a Long-term Endeavor to be
Accomplished via a Series of Small Steps: Some
participants argued that it would be premature to
specify a date and the cost of a long-term human
spaceflight goal, and that the nation should pursue
the larger goal through a series of smaller missions
as NASA's budget allowed, in a "buy it by the yard"
approach. This approach could help sustain momentum
and political support, and would allow many
opportunities for the involvement of international
partners.
THEME 5. Synergy Superseding the Humans-versus-Robots
Dichotomy: Numerous participants called for moving
beyond the view that human and robotic missions must
compete for funding, and instead crafting a human
spaceflight program that exploited the synergies of
using both. Many agreed that, if long-term human
space exploration is the goal, the benefits of both
will be needed, and the mix of the two will depend on
the ultimate goal chosen.
THEME 6. The Long-term Goal Driving All
Implementation Decisions: Warning against repeating
the mistake of the shuttle and space station programs
in making "too many promises to too many people,"
workshop participants stated that the chosen long-term
goal should drive all related decisions. For example,
the goal of achieving long-term human exploration, it
was noted, could provide "a very clear justification"
for the configuration of, and research aboard, the
space station, and the design of the next space
transportation system.
THEME 7. Institutional Concerns: A successful human
spaceflight program, it was felt, would require
significant changes in NASA. Workshop participants
cited a number of concerns with the current situation,
including the lack of independent stakeholders for a
human spaceflight goal, the decline of the U.S. space
industrial base, changes to NASA's mission since the
Apollo program, a lack of management competence
exemplified by repetition of the same mistakes, a lack
of technical competence reflected in NASA's use of old
technologies for the human spaceflight program, and a
lack of openness and honesty in NASA's justification
of many of its programs. Some also felt that the
human spaceflight program would have a better chance
of success if the broad science community expressed
support for it and contributed to making it an
effective and productive program.
The report on the workshop, "Issues and Opportunities
Regarding the U.S. Space Program," which runs nearly
100 pages with appendices, can be requested in pdf
format from the Space Studies Board at ssb@nas.edu.
Some of the suggestions raised at the workshop appear
in line with Bush's proposal for human spaceflight
(see FYI #7), but how many will be incorporated into
NASA's future plans remains to be seen. Two days ago,
at a Senate Commerce, Science and Transportation
Committee hearing, senators expressed interest in the
President's plan for the Moon and Mars, but were
skeptical about the potential cost. More details on
the Moon/Mars proposal will be revealed when the FY
2005 budget request is released next week.
