microgravity

mi·cro·grav·i·ty

M0273850 (mī′krō-grăv′ĭ-tē)n.1. The very slight gravitational field experienced by a mass that is far removed from any other mass, as in intergalactic or interstellar space.2. A condition, such as a free fall or orbital motion, in which acceleration of an object causes it to appear weightless even in the presence of a strong gravitational force.3. A minute shift in the earth's gravitational field that can occur through geologic processes in a region, such as the movement of the earth's crust along fault lines.

microgravity

(ˈmaɪkrəʊˌɡrævɪtɪ) n (Astronautics) the very low apparent gravity experienced in a spacecraft in earth orbit

mi•cro•grav•i•ty

(ˈmaɪ kroʊˌgræv ɪ ti)

n. a condition, esp. in orbit, where the force of gravity is so weak that weightlessness results. [1908–85]

microgravity

(mÿ-kroh-grav -ă-tee) The very low gravity encountered on spacecraft in Earth orbit, leading to a condition of near weightlessness. The behavior of liquids and gases in microgravity differs markedly from that observed on Earth. Hydrostatic pressure is small, sedimentation is suppressed, and dynamic effects, such as thermal convection, disappear. Space missions dedicated to the study of materials and living matter in microgravity include Eureca, the International Microgravity Laboratory, and the US Microgravity Laboratory.

microgravity

[‚mī·krō′grav·əd·ē] (mechanics) A state of very weak gravity, such that the gravitational acceleration experienced by an observer inside the system in question is of the order of one-millionth of that on earth.
