Gaia philosophy (named after Gaia, the Greek goddess of the Earth) is a broadly inclusive term for related concepts that living organisms on a planet will affect the nature of their environment – to make it more suitable for life.
While there were a number of precursors to Gaia theory, the first scientific form of this idea was proposed as the Gaia Hypothesis by James Lovelock, a UK chemist, in 1970.
The Gaia hypothesis deals with the concept of homeostasis, and claim the resident life forms of a host planet coupled with their environment have acted and act as a single, self-regulating system.

  Gaia probe - Wikipedia, the free encyclopedia
Gaia is an astrometry space mission, and a successor to the ESA Hipparcos mission.
Its objectives comprise (a) astrometric (or positional) measurements, determining the positions, distances, and annual proper motions of stars with an accuracy of about 20 µas (microarcsecond) at 15 mag, and 200 µas at 20 mag; (b) photometric measurements, providing multi-colour multi-epoch observations of each detected object; and (c) radial velocity measurements.
Gaia will create an extremely precise three-dimensional map of stars throughout our Milky Way galaxy and beyond, and map their motions which encode the origin and subsequent evolution of the Milky Way.

 Gaia
Gaia (formerly GAIA for Global Astrometric Interferometer for Astrophysics, due to technology change, the transscription is no longer true) will survey more than one billion stars, including many of the closest stars to the Sun.
Gaia is a single spacecraft, consisting of three telescopes that will constantly sweep the sky, recording every visible celestial object that crosses its lines of sight.
The Gaia payload comprises two `Astro' (astrometric) telescopes with a common focal plane, and a `Spectro' telescope comprising a radial velocity spectrograph and a medium-band photometer.

 gaia
The Gaia hypothesis attempts to prove that the air, waters, rock, and life on Earth are all interconnected.
This postulates that the physical and chemical condition of the surface of the Earth, of the atmosphere, and of the oceans has been and is actively made fit and comfortable by the presence of life itself.
By 1973, they had refined the Gaia hypothesis in publications of Tellus and Icarus to be "the notion of the biosphere as an adaptive control system that can maintain the Earth in homeostasis." (Lovelock 1990).

Cronus, the son of Uranus and Gaia and the youngest of the twelve Titans.
It is written that Uranus, who in one version, hid his children away in the bowels of the earth (Tartarus) as he was aghast at the sight of them, in reality he was fearful of their great strength and power.
Gaia found her offspring uncomfortable and also painful and when she found the discomfort too much to bear she hatched a plan, which was to end the passions of Uranus, so no more offspring could be produced and that would be the ending of her hurt.

Gaia, as we shall see, has continuity with the past back to the origins of life, and in the future as long as life persists.
Gaia, as a total planetary being, has properties that are not necesarily discernable by just knowing individual species or populations of organisms living together...
Is the idea of Gaia only a romantic and dramatized description of the terrestrial biosphere and its effects, or is there a planetary being, whose life cycle must be counted in the billions of years, which spawns these evolving life forms to suit the purpose of its being.

 Goldsmith: Gaia and evolution.
Gaia has, in effect, created herself, not in a random manner but in a goal-directed manner since the system is highly stable and is capable of maintaining its stability in the face of internal and external challenges.
It is, in fact, a cybernetic system, and for this to be possible, Gaia must display considerable order, indeed, she must be seen as a vast co-operative enterprise,very much as nature was seen by the 'natural theologists' of the 19th century.
Instead, Gaia must be seen, as Lovelock sees her, as a vast co-operative enterprise geared to the maintenance of its overall structure in the face of change.

 ESA Portal - Expanding Frontiers - Mapping the Galaxy, and watching our backyard
Gaia, a spacecraft which will carry two of the most sensitive cameras ever made, is due to be launched in 2010.
It will take five years to detect such a vast quantity of objects, some of which are incredibly faint, and another three years to plot them all in a giant three-dimensional computerised model that shows not only their current position, but their direction of motion, colour and even their composition.
Their detection is a by-product of the main goal of Gaia which is to precisely measure the location, motion and composition of several millions of stars in our Galaxy.

 THE GAIA HYPOTHESIS: IMPLICATIONS FOR A CHRISTIAN POLITICAL THEOLOGY OF THE ENVIRONMENT
Gaia is significant because it fuses scientific insight and religious imagination in a potentially energizing and transformative way, challenging persons across a broad spectrum of disciplines to deal in an integrative fashion with the ecological crisis.
To probe these questions, Lovelock examined what sustained life on Earth, and, arguing from his strength as an atmospheric chemist, found his answer in the composition of the Earth's atmosphere, with its delicate balance of oxygen, hydrogen, nitrogen, methane, and traces of other elements.
For Thomas Berry, a Passionist priest and "geologian," the wellsprings of the Gaia theory are part of a continuum through which a new sense of the sacredness of the cosmos is emanating from modern science.

 Class 4 probe - Memory Alpha, the Star Trek Wiki
Class-4 probes were also used that year by the USS Enterprise-D to monitor the formation of a new star in the Detrian system.
In 2372, a class-4 probe was proposed to be used to penetrate an artificial wormhole to prove it were stable enough for space travel.
Later that year, a class-4 probe was used to transmit a location signal, as well as several farewell recording from the crew of the Defiant, after being trapped behind an energy barrier surrounding the planet Gaia.

 Probe Set To Dial 1-800-ENTANGLEMENT
The probe the researchers are building is a transistor with an active channel measuring just a few billionths of meter across.
The researchers hope that when the electron "tunnels" (winks out of existence in one place and appears in another), they can establish a quantum critical state in the electrodes where the particle is trapped.
The new probe should permit the physicists to introduce competition between two quantum effects - magnetic quantum entanglement and coupling with spin waves.

 Gaia Summary
GAIA theory was first proposed by the English scientist James Lovelock in 1979 to explain how and why, as life appeared on the planet and grew abundant, its evolution and the earth's evolution merged into a single dynamic system he called Gaia.
Gaia is thus not only an attempt to specify a unifying framework for the operation of the entire earth system, but also an explicit critique of the existing organization of knowledge inquiry.
Gaia has had little effect on research agendas, however, and the number of working scientists willing to be associated with the hypothesis is small—perhaps less than a dozen.

 Part One
Co-evolutionary Gaia asserts that the biota influence their abiotic environment, and that the environment in turn influences the evolution of the biota by Darwinian process.
The Gaia Sutra combines Lovelock, Bateson, and Chalmers and proclaims a planetary Gaia Mind a complex system system that meets Bateson's criteria for mind, born of the One Mind that is the ground of all being.
Since the nature of the Gaia Mind is different from the nature of the human mind, it is reasonable to suppose that the nature of Gaia consciousness is different from that of human consciousness.

Gaia theory provides a compelling logic for biodiversity.
However, NASA was more interested in sending a probe to Mars than to answer the question of whether life existed in Mars and hence these findings were pushed under the carpet at that time.

The probe continued to transmit data after landing — extending the probe's expected lifetime — which was a pleasant surprise for the scientists.
The fact that the probe continued transmitting data after landing could mean that it landed on land, rather than in liquid, Lebreton said, but it is really too early to tell.
As the probe descended, it drifted over a plateau (centre of image) and was heading towards its landing site in a dark area (right).
