NASA's Journey to Mars: Pioneering Next Steps in Space Exploration
Author: National Aeronautics and Space Administration
Publisher: Government Printing Office
ISBN:
Category : Science
Languages : en
Pages : 36
Book Description
This document communicates NASA’s strategy and progress to learn about the Red Planet, to inform us more about our Earth’s past and future, and may help answer whether life exists beyond our home planet. Together with NASA’s partners in academia and commercial enterprises, NASA’s vision is to pioneer Mars and answer some of humanity’s fundamental questions: • Was Mars home to microbial life? Is it today? • Could it be a safe home for humans one day? • What can it teach us about life elsewhere in the cosmos or how life began on Earth? • What can it teach us about Earth’s past, present, and future?

Comparison of Trajectory Profiles and Nuclear-propulsion-module Arrangements for Manned Mars and Mars-Venus Missions
Author: Edward A. Jr Willis
Publisher:
ISBN:
Category : Nuclear propulsion
Languages : en
Pages : 36
Book Description
A brief comparison is made between opposition class (with three impulse return), conjunction class, Venus swing-by to Mars and Mars-Venus double stopover trajectories. Vehicle configurations based on NERVA-I engines of varying life and restart capability are considered. It is found that the opposition and Venus swingby trajectories to Mars yield competitive mission performance; the double stopover entails about 30-percent penalties in initial mass and trip time; and that the minimum-weight vehicle uses a single, restartable engine.
