Photobioreactors in Life Support Systems
2015Life support systems for long-term space missions or extraterrestrial installations have to fulfill major functions such as purification of water and regeneration of atmosphere as well as the generation of food and energy. For almost 60 years ideas for biological life support systems have been collected and various concepts have been developed and ...

Life support systems for Mars transit
Advances in Space Research, 1992The long-held human dream of travel to the stars and planets will probably be realized within the next quarter century. Preliminary analyses by U.S. scientists and engineers suggests that a first trip to Mars could begin as early as 2016. A proposal by U.S.S.R. space planners has suggested that an effort involving the cooperation and collaboration of

Bioregenerative life-support systems
The American Journal of Clinical Nutrition, 1994Long-duration future habitation of space involving great distances from Earth and/or large crew sizes (eg, lunar outpost, Mars base) will require a controlled ecological life-support system (CELSS) to simultaneously revitalize atmosphere (liberate oxygen and fix carbon dioxide), purify water (via transpiration), and generate human food (for a ...

A mechanical cardiopulmonary life-support system
Resuscitation, 1974Abstract A mechanical cardiopulmonary resuscitator is described. Its use in cardiac arrest is discussed and the machine is shown to be safe, simple to operate, and more efficient than manual techniques, both in the hospital and in the ambulance services.

COMPOSTING IN ADVANCED LIFE SUPPORT SYSTEMS
Acta Horticulturae, 1998Space missions of extended duration are currently hampered by the prohibitive costs of external resupply. To reduce the need for resupply, the National Aeronautics and Space Administration (NASA) is currently testing methods to recycle solid wastes, water, and air.

Basic human needs—a breathable atmosphere, water, food, and waste removal— are all natural life support functions and in normal life they are basically provided by our planet’s ecological system. These basic needs are the same for humans in space as on Earth, but nature must be copied by mechanical and physicochemical equipment.

Considerations of design for life support systems
Advances in Space Research, 2003During the design phase for construction of artificial ecosystems, the following considerations are important. (1) Influences on living things in the ecosystem, such as lifestyles and physiological functions caused by stresses due to environmental changes.

Abstract There is an astonishing variety and abundance of microscopic life that underpins the ecology of natural waters. The aquatic microbiome—made up of viruses, bacteria, archaea, and microbial eukaryotes—is central to the healthy functioning of lake ecosystems and their responses to environmental change.

It is certainly true that robots like the Mars Pathfinder, Spirit, and Opportunity have shown that a lot of scientific information about a planet’s surface can be gathered by sending robots instead of people. As well, it can be done significantly cheaper. But imagine that you wanted to go to Paris.
