Retained from the first edition, Donald Rapp looks at human missions to Mars from an engineering perspective. He divides the mission into a number of stages: Earth's surface to low-Earth orbit (LEO); departing from LEO toward Mars; Mars orbit insertion and entry, descent and landing; ascent...

Energy sustainability and redundancy for surface habitats, life support systems and scientific instrumentation represent one of the highest-priority issues for future crewed missions to Mars. However, power sources utilized for the current class of robotic missions to Mars may be potentially dangerous nea...
The monumental challenge of sending humans to Mars for a lengthy stay and then returning them safely to Earth is mind-boggling. Unlike previous space missions, when these astronauts leave Earth, they will not be able to return for almost three years. The trip to Mars will take between four ...
a UCL A research geophysicist and co-author of the paper."This study shows that while space radiation imposes (强加) strict limitations on how heavy the spacecraft can be and the timing of launch, and it presents technological difficulties for human missions to Mars, such a mission is possib...
have provided a rich set of data that has dramatically altered our understanding of Mars, in a way that both enhances the feasibility of conducting human missions to Mars (i.e., the apparent abundance of near-global, subsurface water, at some depth), while also presenting new potential hazard...
"It's looking more encouraging that water ice could be available at depths shallow enough that could be used as resources for human missions to Mars," Angel Abbud-Madrid, the director of the Center for Space Resources at the Colorado School of Mines told National Geographic. Abbud...
