Scientific and Technical Aerospace Reports


Book Description

Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.




Mars Sample Return Mission


Book Description

Mission and vehicle concepts were developed for obtaining surface and sub-surface samples of Mars, by a roving vehicle, and returning the samples to Earth.




Preventing the Forward Contamination of Mars


Book Description

Recent spacecraft and robotic probes to Mars have yielded data that are changing our understanding significantly about the possibility of existing or past life on that planet. Coupled with advances in biology and life-detection techniques, these developments place increasing importance on the need to protect Mars from contamination by Earth-borne organisms. To help with this effort, NASA requested that the NRC examine existing planetary protection measures for Mars and recommend changes and further research to improve such measures. This report discusses policies, requirements, and techniques to protect Mars from organisms originating on Earth that could interfere with scientific investigations. It provides recommendations on cleanliness and biological burden levels of Mars-bound spacecraft, methods to reach those levels, and research to reduce uncertainties in preventing forward contamination of Mars.







Encyclopedia of the Solar System


Book Description

Long before Galileo published his discoveries about Jupiter, lunar craters, and the Milky Way in the Starry Messenger in 1610, people were fascinated with the planets and stars around them. That interest continues today, and scientists are making new discoveries at an astounding rate. Ancient lake beds on Mars, robotic spacecraft missions, and new definitions of planets now dominate the news. How can you take it all in? Start with the new Encyclopedia of the Solar System, Second Edition.This self-contained reference follows the trail blazed by the bestselling first edition. It provides a framework for understanding the origin and evolution of the solar system, historical discoveries, and details about planetary bodies and how they interact—and has jumped light years ahead in terms of new information and visual impact. Offering more than 50% new material, the Encyclopedia includes the latest explorations and observations, hundreds of new color digital images and illustrations, and more than 1,000 pages. It stands alone as the definitive work in this field, and will serve as a modern messenger of scientific discovery and provide a look into the future of our solar system.· Forty-seven chapters from 75+ eminent authors review fundamental topics as well as new models, theories, and discussions· Each entry is detailed and scientifically rigorous, yet accessible to undergraduate students and amateur astronomers· More than 700 full-color digital images and diagrams from current space missions and observatories amplify the chapters· Thematic chapters provide up-to-date coverage, including a discussion on the new International Astronomical Union (IAU) vote on the definition of a planet· Information is easily accessible with numerous cross-references and a full glossary and index

Book Description




Use of Extraterrestrial Resources for Human Space Missions to Moon or Mars


Book Description

This book presents a detailed, independent review of essentially all the technical aspects of “in situ resource utilization” (ISRU), offering the first in-depth discussion of the issues of crew size, ascent from Mars, and ISRU processes. It also provides data on lunar ISRU not previously available to the public. This new edition provides a short synopsis of the Mars mission, and discusses various topics, including solid oxide electrolysis, which promises to be an important part of the ISRU picture. In addition, it explores ancillary needs for Mars ISRU and how to obtain water on Mars. It is the go-to resource for professionals involved in planning space missions or working on ISRU processes, as well as students planning careers in space technology.
