Viking Spacecraft Biological Experiments
The two Viking spacecraft each carried four types of biological experiments to the surface of Mars in the late 1970s. These were the first Mars landers to carry out experiments to look for biosignatures of life on Mars. The landers used a robotic arm to put soil samples into sealed test containers on the craft. The two landers were identical, so the same tests were carried out at two places on Mars' surface, Viking 1 near the equator and Viking 2 further north.

Famous quotes containing the words viking, biological and/or experiments:
“Rice and peas fit into that category of dishes where two ordinary foods, combined together, ignite a pleasure far beyond the capacity of either of its parts alone. Like rhubarb and strawberries, apple pie and cheese, roast pork and sage, the two tastes and textures meld together into the sort of subtle transcendental oneness that we once fantasized would be our experience when we finally found the ideal mate.”
—John Thorne, U.S. cookbook writer. Simple Cooking, “Rice and Peas: A Preface with Recipes,” Viking Penguin (1987)
“If the most significant characteristic of man is the complex of biological needs he shares with all members of his species, then the best lives for the writer to observe are those in which the role of natural necessity is clearest, namely, the lives of the very poor.”
—W.H. (Wystan Hugh)
“The man who invented Eskimo Pie made a million dollars, so one is told, but E.E. Cummings, whose verse has been appearing off and on for three years now, and whose experiments should not be more appalling to those interested in poetry than the experiment of surrounding ice-cream with a layer of chocolate was to those interested in soda fountains, has hardly made a dent in the doughy minds of our so-called poetry lovers.”
—John Dos Passos (1896–1970)
