Book excerpt: How feasible is a manned Mars flight? How soon will it be possible? How long will it take? What kind of spacecraft will make the journey? What kind of data will be collected? What are the advantages of a manned flight over an unmanned? Mission to Mars discusses these questions and more in this serious, documented treatment of the not-too-distant manned expedition to Mars. The shuttle has proved successful and an enthusiastic boost to American interest in space. But while many laypeople wonder “what’s next,” scientists are planning what they feel is the next logical step. Drawing on the vast amount of data sent back by Viking orbiters and probes, and existing developments in propulsion and space technology, space experts all over have been speculating, analyzing, and exchanging ideas relative to the long-awaited mission to Mars. Other factors, critical to an intelligent discussion of such an undertaking are included here: spaceship design and assembly, propulsion systems, navigation principles, life support systems, selecting a landing site, scientific activities on Mars, cost factors, political and social issues.

Book excerpt: Twenty-six essays written by workers in the space industry and interested lay people make a case for exploring Mars, arguing for the scientific objectives that could be achieved in the Martian "frontier" and even providing a cost and benefit analysis. The discussions suggest specific strategies in "getting there," flight profiles, and rocket designs utilizing nuclear electric propulsion. However, the questions remains--what happens when we arrive? In response, the authors speculate on life support, biomedical issues, transportation, and living spaces based on Biosphere 2 results. Lacks an index.

Available in PDF, EPUB and Kindle. Book excerpt: This study, commissioned by the National Aeronautics and Space Administration (NASA), examines the role of robotic exploration missions in assessing the risks to the first human missions to Mars. Only those hazards arising from exposure to environmental, chemical, and biological agents on the planet are assessed. To ensure that it was including all previously identified hazards in its study, the Committee on Precursor Measurements Necessary to Support Human Operations on the Surface of Mars referred to the most recent report from NASA's Mars Exploration Program/ Payload Analysis Group (MEPAG) (Greeley, 2001). The committee concluded that the requirements identified in the present NRC report are indeed the only ones essential for NASA to pursue in order to mitigate potential hazards to the first human missions to Mars.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a highly readable yet realistic view of the possibilities for human missions to Mars. It provides for the first time a ‘level-headed’ assessment of plans for human exploration of Mars to counteract the tendency of space agencies to take an over-optimistic approach to such interplanetary missions. The author presents a detailed analysis of why, in his opinion, the current NASA approach will fail to send humans to Mars before 2080.
Download or read book Martian Outpost written by Erik Seedhouse and published by Springer Science & Business Media. This book was released on 2010-04-11 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mars Outpost provides a detailed insight into the various technologies, mission architectures, medical requirements, and training needed to send humans to Mars. It focuses on mission objectives and benefits, and the risks and complexities that are compounded when linked to an overall planet exploration program involving several expeditions and setting up a permanent presence on the surface. The first section provides the background to sending a human mission to Mars. Analogies are made with early polar exploration and the expeditions of Shackleton, Amundsen, and Mawson. The interplanetary plans of the European Space Agency, NASA, and Russia are examined, including the possibility of one or more nations joining forces to send humans to Mars. Current mission architectures, such as NASA’s Constellation, ESA’s Aurora, and Ross Tierney’s DIRECT, are described and evaluated. The next section looks at how humans will get to the Red Planet, beginning with the preparation of the crew. The author examines the various analogues to understand the problems Mars-bound astronauts will face. Additional chapters describe the transportation hardware necessary to launch 4-6 astronauts on an interplanetary trajectory to Mars, including the cutting edge engineering and design of life support systems required to protect crews for more than a year from the lethal radiation encountered in deep space. NASA’s current plan is to use standard chemical propulsion technology, but eventually Mars crews will take advantage of advanced propulsion concepts, such as the Variable Specific Impulse Magnetoplasma Rocket, ion drives and nuclear propulsion. The interplanetary options for reaching Mars, as well as the major propulsive maneuvers required and the trajectories and energy requirements for manned and unmanned payloads, are reviewed . Another chapter addresses the daunting medical problems and available countermeasures for humans embarking on a mission to Mars: the insidious effects of radiation on the human body and the deleterious consequences of bone and muscle deconditioning. Crew selection will be considered, bearing in mind the strong possibility that they may not be able to return to Earth. Still another chapter describes the guidance, navigation, and control system architecture, as well as the lander design requirements and crew tasks and responsibilities required to touch down on the Red Planet. Section 3 looks at the surface mission architectures. Seedhouse describes such problems as radiation, extreme temperatures, and construction challenges that will be encountered by colonists. He examines proposed concepts for transporting cargo and astronauts long distances across the Martian surface using magnetic levitation systems, permanent rail systems, and flying vehicles. In the penultimate chapter of the book, the author explains an adaptable and mobile exploration architecture that will enable long-term human exploration of Mars, perhaps making it the next space-based tourist location.

This book was released on 2018-08-20 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mars exploration is a candidate pathway to expand human presence and useful activities in the solar system. There are several propulsion system options being considered to place the Mars payload on its inter-planetary transfer trajectory. One propulsion option is the use of Solar Electric Propulsion (SEP) to spiral out with the Mars payload from an initial Low Earth Orbit (LEO) to an elliptical High Earth Orbit (HEO). This report, presented in annotated facing page format, describes the work completed on the design of a crew taxi propulsion stage used in conjunction with the SEP. Transportation system/mission analysis topics covered in this report include sub-system analysis, trajectory profile description, mass performance and crew taxi stage sizing, stage configuration, stage cost, and Trans-Mars Injection (TMI) launch window. The high efficiency of SEP is used to provide the major part of the TMI propulsion maneuver. Orbital energy is continuously added over a period of approximately twelve months. The SEP and Mars payload follow a spiral trajectory from an initial LEO to a final elliptical HEO. A small chemical stage is then used to provide the final part of the TMI. The now unloaded SEP returns to LEO to repeat another spiral trajectory with payload to HEO. The spiral phase of the SEP's trajectory takes several months to reach HEO, thus significantly increasing the exposure time of the crew to zero-gravity. In order to minimize the long zero-gravity effects, a high thrust chemical stage delivers the crew to the SEP's HEO. The crew rendezvous with the Mars payload in HEO. After a checkout period the Mars payload with the crew is injected onto a Trans-Mars Trajectory by a small chemical stage.Young, ArchieMarshall Space Flight CenterMARS EXPLORATION; SYSTEMS ANALYSIS; DESIGN ANALYSIS; TECHNOLOGY ASSESSMENT; CHECKOUT; SOLAR ELECTRIC PROPULSION; WEIGHTLESSNESS; ANNOTATIONS; COSTS; ELLIPTICAL ORBITS; EXPOSURE; HIGH THRUST; INJECTION; LAUNCH WINDOWS; LOW EARTH OR

Book excerpt: On the 20th anniversary of the first human landing on the Moon, President George H.W. Bush stood atop the steps of the National Air and Space Museum in Washington, D.C. and proposed a long-range human exploration plan that included the successful construction of an orbital space station, a permanent return to the Moon, and a mission to Mars. This enterprise became known as the Space Exploration Initiative (SEI). The president charged the newly reestablished National Space Council with providing concrete alternatives for meeting these objectives. To provide overall focus for the new initiative, Bush later set a thirty-year goal for a crewed landing on Mars. Within a few short years after this Kennedyesque announcement, however, the initiative had faded into history the victim of a flawed policy process and a political war fought on several different fronts. The story of this failed initiative was a tale of organizational, cultural, and personal confrontation by key protagonists and critical battles. Some commentators have argued that SEI was doomed to fail, due primarily to the immense budgetary pressures facing the nation during the early 1990s. The central thesis of Mars Wars: The Rise and Fall of the Space Exploration Initiative suggests, however, that failure was not predetermined. Instead, it was the result of a deeply flawed decision-making process that failed to develop (or even consider) policy options that may have been politically acceptable given the existing political environment.
Download or read book Mars The Next Step written by Smith A E and published by CRC Press. This book was released on 1989-01-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conquest of Earth's moon was merely a precursor to a more dramatic step forward, which will take men and women to an outpost that might eventually become a second home for the human race. Mars: The Next Step illustrates how the only feasible colonization of another planet in our solar system will be on Mars. The author addresses the various questions surrounding this theory with frank scientific caution that in no way obscures his vigorous enthusiasm and, above all, optimism for mankind's future in space. This vivid and entertaining book explores "terraforming" (planetary engineering), which could turn Mars into a more congenial environment for humans, both in terms of changing the harsh climate of the planet and the production of plants able to thrive there by means of genetic engineering. The book includes numerous diagrams of possible manned spacecraft, along with color pictures of Mars taken on previous unmanned missions.
