This Roadmap is the product of deliberation and
discussion by the Origins Subcommittee of
NASAs Space Science Advisory Committee,
working with representatives from NASAs field
centers and with substantial input from the
astronomical community. The Roadmap sets out
a plan for a twenty-year period at the beginning
of the millennium, with particular emphasis on
activities advocated for new mission starts in the
near-term (20052010) or mid-term (20102015)
time frame.
