Artificial Gravity and Abort Scenarios via Tethers for Human Missions to Mars
Minimum-mass tether designs are developed for a spinning human transport that not only provides artificial gravity, but also the potential for free-return aborts. The investigation reveals that severing the tether can provide a propellant-free boost to return astronauts to Earth in the event of an aborted landing on Mars. Earth–Mars–Earth, Earth–Mars–Venus–Earth, and Earth–Venus–Mars–Earth traj...
متن کاملArmchair Missions to Mars
Computer simulation of long missions in space can provide experience and predictions without the expense and risk of actual flights. Simulations are most helpful if they can model the behavior of key psychological factors of the crew over time, rather than simply predicting overall mission success. Because of the lack of experience with interplanetary trips and the problems of generalizing and ...
متن کاملHuman and Robotic Exploration Missions to Phobos prior to Crewed Mars Surface Missions
Phobos is a scientifically significant destination that would facilitate the development and operation of the human Mars transportation infrastructure, unmanned cargo delivery systems and other Mars surface systems. In addition to developing systems relevant to Mars surface missions, Phobos offers engineering, operational, and public engagement opportunities that could enhance subsequent Mars s...
متن کاملConcept for Manned Missions to Mars
In a previous paper, a new scenario for human missions to Mars has been presented. It can be named the 2-4-2 concept. The idea is to minimize IMLEO and the payload on Mars with a crew of only two astronauts. There are two astronauts in each rocket at departure from Earth. They meet on Mars to form a team of four and the pairs are reconstituted for the return (2-4-2). In the previous study it wa...
متن کاملCombining meteorites and missions to explore Mars.
Laboratory studies of meteorites and robotic exploration of Mars reveal scant atmosphere, no evidence of plate tectonics, past evidence for abundant water, and a protracted igneous evolution. Despite indirect hints, direct evidence of a martian origin came with the discovery of trapped atmospheric gases in one meteorite. Since then, the study of martian meteorites and findings from missions hav...
