This book covers the possible manned mission to Mars first discussed in the 1950s and still a topic of much debate, addressing historic and future plans to visit the Red Planet. Considering the environmental dangers and the engineering and design needed for a successful trip, it covers every aspect of a possible mission and outpost. The chapters explain the motivations behind the plan to go to Mars, as well as the physical factors that astronauts on manned missions will face on Mars and in transit. The author provides a comprehensive exposure to the infrastructure needs on Mars itself, covering an array of facilities including power sources, as well as addressing earth-based communication networks that will be necessary. Mechanisms for return to Earth are also addressed. As the reality of a manned Mars voyage becomes more concrete, the details are still largely up in the air. This book presents an overview of proposed approaches past, present, and future, both from NASA and, increasingly, from other space agencies and private companies. It clearly displays the challenges and the ingenious solutions involved in reaching Mars with human explorers.

这本书首先讨论了20世纪50年代首次提出的载人火星任务，并且仍然是一个备受争议的话题，探讨了前往红色星球的历史和未来计划。考虑到环境危险以及为了成功旅行所需的工程和技术设计，它涵盖了可能的载人任务和基地的所有方面。章节解释了前往火星计划背后的动力，同时也介绍了人类航天员在火星上及途中将面临的物理因素。作者提供了对火星本身基础设施需求的全面介绍，包括电源等设施，并且还涉及到了必要的地球上的通讯网络。还讨论了返回地球的方法。随着载人火星旅行的现实性变得越来越具体，细节仍然很大程度上悬而未决。这本书概述了过去的、现在的以及未来的各种设想方法，无论是来自NASA还是越来越多地来自其他航天机构和私人公司。它清晰地展示了人类探索火星所需的挑战和巧妙解决方案。
