The interior of the Apollo PLSS Diagram of the A7L PLSS and OPS, with interfaces to the astronaut and the Lunar Module cabin. The portable life support system used in the Apollo lunar landing missions used lithium hydroxide to remove the carbon dioxide from the breathing air, and circulated water in an open loop through a liquid-cooled garment, expelling the water into space, where it turned ...
A mini survival kit contains essential outdoor survival tools and supplies. It is intended to be carried on one's person at all times, be appropriate to all environments, and be a comprehensive kit without being too large. Mini survival kits are intended to provide the basic needs of a survival situation, self-rescue, assistance or a return to ...
A lunar cycler or Earth–Moon cycler is a cycler orbit, or spacecraft therein, which periodically passes close by the Earth and the Moon, using gravity assists and occasional propellant-powered corrections to maintain its trajectories between the two. If the fuel required to reach a particular cycler orbit from both the Earth and the Moon is ...

There are two points in space where an elevator's docking port could maintain a stable, lunar-synchronous position: the Earth-Moon Lagrange points L 1 and L 2.The 0.055 eccentricity of the lunar orbit means that these points are not fixed relative to the lunar surface : the L 1 is 56,315 km +/- 3,183 km away from the Earth-facing side of the Moon (at the lunar equator) and L 2 is 62,851 km ...
Military survival training has greater focus on specialized military survival equipment, survival kits, signaling, rescue techniques, and recovery methods. Military personnel are almost always better prepared for survival situations because of obvious inherent risk in their activities (and their training and equipment).
Survival skills are techniques used to sustain life in any type of natural environment or built environment. These techniques are meant to provide basic necessities for human life, including water, food, and shelter. Survival skills also support proper knowledge and interactions with animals and plants to promote the sustaining of life over time.
An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.
