ABSTRACT
A simple pencil-and-paper
bounding study says this is possible:
one 9-month round trip, 6 men, 16 one-week landings, nothing thrown away, minimal technology developments (but
fairly certain of success), no new
launch rockets, under $8 billion in
direct launch costs, possibly as
soon as 5 years.
This mission study is a
clean-sheet design. The differences
with other studies are: (1) legacy
hardware and contractors are ignored, (2) new developments are minimal, and (3)
maximum self-rescue is designed into every phase.
Only direct launch costs were
computed: under $8 billion. A guess for the overall program might be
3-4 times that amount, if done by a lean, efficient contractor. All mission assets are reusable, and
left in place around Earth and Mars for the next mission to refuel and
reuse.
