Nuclear-powered Earth-orbital-launch probes can place greater payloads in orbit about Mars than chemical vehicles if reactor power exceeds 50 mw. Suitable reactor powers for this missionARE ABOUT 150, 400, AND 1000 MW FOR 33,000-, 81,000-, AND 200,000-LB VEHICLES, RESPECTIVELY. Whereas a 33,000-lb vehicle requires greater than a 200-day coast, a 145-day coast is feasible for an 81,000-lb vehicle. A hydrogen temperature of 4000 F in the nozzle appears to be a good compromise. Use of a solid-propellant rocket to achieve an orbit about Mars from coast yields no payload advantage. Using optimum firing dates, a 33,000-lb vehicle could orbit an acceptable payload about Mars, and an 81,000-lb vehicle could land freight on Mars. (Author).

This classic on space travel was first published in 1953, when interplanetary space flight was considered science fiction by most of those who considered it at all. Here the German-born scientist Wernher von Braun detailed what he believed were the problems and possibilities inherent in a projected expedition to Mars. Today von Braun is recognized as the person most responsible for laying the groundwork for public acceptance of America's space program. When President Bush directed NASA in 1989 to prepare plans for

Arsic unpacks Ralph Waldo Emerson's repeated assertion that our reality and our minds are in constant flux. Her readings of a broad range of Emerson's writings are guided by a central question: what does it really mean to maintain that everything fluctuates, is relational, and so changes its identity?
