Science
Gravity on Mars is only about 38% as strong as it is on Earth, and the long-term effects of such reduced gravity are unknown. Astronauts who are weightless for long periods of time lose significant amounts of bone and muscle mass. It is unclear if the gravity on Mars is strong enough to avoid or minimize these health problems. The Mars Gravity Biosatellite was meant to provide data on how mammalian health is affected by long-term exposure to lower levels of gravity, focusing on bone loss, changes in bone structure, muscle atrophy, and changes in the inner ear. The results from the experiment would be compared against a variety of earth based controls, including vivarium, hindlimb suspension, partial weight suspension, flight habitat effects, and short-radius centrifuge testing.

Famous quotes containing the word science:
“There does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit of the tree which bears it.”
—Louis Pasteur (18221895)
“We have not given science too big a place in our education, but we have made a perilous mistake in giving it too great a preponderance in method in every other branch of study.”
—Woodrow Wilson (18561924)
“The well-educated young woman of 1950 will blend art and sciences in a way we do not dream of; the science will steady the art and the art will give charm to the science. This young woman will marryyes, indeed, but she will take her pick of men, who will by that time have begun to realize what sort of men it behooves them to be.”
—Ellen Henrietta Swallow Richards (18421911)
