But the prospect of human beings landing there and exploring that red surface seems even more enticing. No wonder I was stirred by President Bush when he gave the reasons for a putative manned mission to Mars. "Why the moon? Why Mars?" he asked in a moment of soaring oratory. "Because...
How many manned missions were in Project Apollo? How many satellites does the asteroid belt have? How many satellites does Mars have? How many space shuttle flights were there in 1987? How many people are on the International Space Station normally?
This in-situ resource utilization (ISRU) program allows dramatic reduction on the mass of materials that must be transported from the Earth, and is an enabling technology for a manned mission to Mars. A key part of the ISRU strategy is to use the Martian atmosphere along with hydrogen ...

1. The money spent on manned space exploration is spent right here on Earth and most of it is spent in the US. We do not yet have a Bank of the Milky Way, the First International Bank of Mars, or a Lunar Mutual Savings and Loan. The money that is spent goes to manufacturing, res...
Logsdon on a not-so-obvious incentive for manned space travel: “Space exploration can also serve as a stimulus for children to enter the fields of science and engineering.” Vernikos on the R.O.I. of space travel: “Economic, scientific and technological returns of space exploration have fa...
