MARS Aerobraker Vehicle --with Shuttle To MARS Faster/Cheaper Than other Approaches
The next President and his NASA administrator should also consider a change in the next goal of the U.S. manned space program as well as a change in the hardware to achieve that goal. Scientific interest now centers on Mars rather than on the moon. Four of the five elements of a manned mission to Mars are already in place:
1) The space shuttle (the launch vehicle)
2) The International Space Station, or ISS (the assembly and launch platform for the Trans Mars vehicle)
3) Extensive experience with on-orbit assembly
4) Numerous unmanned precursor missions to Mars
The only missing element is the Mars Aerobraker Vehicle (MAV) to transport the expected three astronauts to and from Mars. Conceptual designs already exist for this vehicle. At an estimated departure weight of 400,000 pounds, a dozen shuttle flights could deliver all needed modules of the MAV to the ISS over a period of years at a cost of perhaps $10 billion. This would leave most of $200 billion (the amount currently contemplated for lunar exploration) to design, build, and assemble the MAV. This redirection would focus the attention and resources of NASA and the aerospace community on the MAV, and would sharpen skills valuable to the nation for further exploration of our solar system. With the manned space program thus redirected, the goal of landing humans on Mars within the next decade appears to be feasible.
