    The Millennial Project: Colonizing the Galaxy in Eight Easy Steps by Marshall T. Savage is a book (published in and reprinted in with an introduction by Arthur C. Clarke) in the field of exploratory engineering that gives a series of concrete stages the author believes will lead to interstellar colonization. Many specific scientific and engineering details are presented, as are. to Mars, we will need closed ecological life support systems which provide sustainable use of limited resources. While such systems are in various stages of development, we lack knowledge regarding the functional stability of closed ecological life support systems (CES) for long-duration space missions. Our global Earth Biosphere CES.

    For example, in the s and s, CELSS and P/C trade-off studies were conducted with gross calculations of the relative benefits of growing higher plants in a closed life support system. These studies were mostly proof-of-concept models for a CELSS, single processor trade-off studies, and life support analyses of the early stages of the ISS. materially closed microcosms’’ (Folsome and Hanson, ). Russian Research – Bios-3 facility Earliest research with bioregenerative life support and closed ecological system research targeted for space appli-cations concentrated on very simple algae-based systems, both in the United States and Russia (Shepelev, ).

Algal culture studies related to a closed ecological life support system (CELSS). [Richard Radmer; Ames Research Center.; Martin Marietta Laboratories.;]. CELSS algal culture studies is the maintenance of continuous cultures. The design of our continuous culture system was derived from the earlier work of several other scientists(I-3) and we believe it represents a summation of their best ideas cast in terms of state-of-the-art technology.

Algal culture studies related to a closed ecological life support system. - Abstract - Europe PMC Abstract: Long-term cultures of Scenedesmus obliquus were maintained in an annular air-lift column operated as a turbidostat.

We observed a linear Cited by: Studies on the steady-state long-term (4 month) culture of Scenedesmus obliquus algae, maintained in an annular air-lift column operated as a turbidostat, were carried out to evaluate the life-supporting possibilities of this system.

Chlorophyll production and cell number as functions of the dry weight were linear at constant illumination. In many respects, algae would be ideal plant components for a biologically-based closed life support system, since they are eminently suited to the closely coupled functions of food production and atmosphere regeneration.

This idea was clearly recognized by an earlier generation of scientists (see, e.g., 8ioregenerative Systems, NASA SP, ). essentially closed nonpolluting, non-deadlock life support technologies will be a noticeable step on the path toward the sustainable development of the noosphere.

To date, all manned space explorations have been relatively short, both in terms of overall time from start to completion of the missions, and also in terms of distance traveled from the Earth.

Mission lengths have been limited by the carrying capacity of the spacecraft, the number of crew, and their life support requirements; all food and life-sustaining materials and supplies had to be.

Harmful algal blooms are one of the consequences of the human impact on aquatic ecosystems, particularly the process of eutrophication. They can cause a variety of deleterious effects, including the poisoning of fish and shellfish, habitat disruptions for many organisms, water discolouration, beach fouling, and even toxic effects for humans.

To develop a ground-based experimental facility for space micro-algal photo-bioreactor which produce algae and oxygen for astronaut and reduce carbon dioxide in closed-ecology life support system.

Likewise a bioregenerative life support system (Bios-3) has been developed in Krasnoyarsk, Siberia which uses higher plants or green algae to remove carbon dioxide, produce oxygen and even food (Salisbury et al., ).

The largest system devised as closed bioregenerative life support system is biosphere 2 located near Oracle, Arizona. A photobioreactor system for efficient oxygen production for a closed ecological life support system (CELSS) is disclosed.

Special features of this system include, e.g., the optical transmission system, uniform light distribution, continuous cycling of cells, gravity independent gas-exchange, and an ultrafiltration unit. The fiber optic based optical transmission system illuminates the reactor.

The closed ecological life support system is much more than a "greenhouse in space." It is a multispecific ecosystem operating in a small closed environment. Even the best systems will have several orders of magnitude less buffering capacity than a normal agricultural environment and will therefore need careful management to provide the.CLOSED ECOLOGICAL SYSTEMS MULTISTAGE ECOLOGICAL SYSTEM Secondary Consumer WASTE STORAGE Primary HCE1 Consumer GreenA 0 Plants Figure I A composite multistage life-support system.

for a man-day system. Its possibility had been suggested in by Bowman (8). Bya conference on photosynthetic gas exchangers was sponsored by the Office.It considers people within an ecological context and focuses on sustaining all components of Earth’s life-support system by preventing human actions that would degrade them.

In an ecologically sustainable economy, natural goods and services should be utilized only in ways that do not compromise their future availability and do not endanger.
