摘要：probes have been utilized in some of the
most fascinating discoveries that mankind has ever
experienced, and capture the awe and wonder of children
and scientists alike. The amount of information they
produce overshadows the fact that these silent travelers
have only existed for less than fifty years and undertake
the riskiest traveling ever mapped. The entire field of
planetary science owes an immense debt to these probes
for their tireless dedication, endurance, and steadfast
reliability. Each different family of probes is a unique
state-of-the-art technological creation designed to
perform flawlessly and endure the harshest environments
known. Either spectacular successes or colossal failures
are the end result of the efforts of the scientists, engineers,
and computer technicians connected to these mechanical
extensions of human curiosity.
However, the sense of wonder that these robotic
surveyors create comes after a long process of planning,
design, and construction. Often, the journey from idea to
launch can span twenty years or more and must survive
critics, budgetary cuts, economic fluctuations, and
changes in the political spectrum. It is almost like a
rugged training period for the embryonic probe
foreshadowing the rougher tasks that lie ahead in its
existence. In order to budget for the creation, launch,
mission, and afterlife of a planetary probe, NASA
follows a complicated and dynamic costing process. This
system attempts to plan, monitor, and restrain the costs
involved while still creating a viable machine that is at
the pinnacle of contemporary engineering and technology
