Antarctica has offered scientists a means of reaching and researching beyond Earth without leaving it.
Various harsh and challenging Antarctic environments have served as testing sites for equipment destined for the moon, Mars and beyond. Its ice has collected meteorites that arrive from extraterrestrial sources. And it is one of the best places on Earth from which to observe the universe.
Since the start of the 20th century, scientists have drawn parallels between Antarctic environments and those that can be found beyond our planet. In 1901, the Australian physicist Louis Bernacchi compared being in Antarctica to what he thought it would be like on the moon: "a dead silent world above you, and a dead silent world at your feet." By the mid-20th century, Antarctic environments were frequently used as approximations of extraterrestrial worlds. NASA officials traveled to the Antarctic "because this was as close to lunar conditions as we could get here on Earth," as one of them, Ernst Stuhlinger, put it in 1968.
In preparation for the Viking mission to Mars in 1975–76, several microbiologists conducted research in the McMurdo Dry Valleys, convinced that this region of Antarctica closely resembled Mars. This type of research continues today. Scientists continue to test technologies created for space exploration in the Antarctic, including spacesuits, robotics and food production facilities, hoping that success in the Antarctic environment will translate into success in the more extreme environments of space.
Likewise, Antarctic workers have been studied to learn about the psychological aspects of long-term isolation and small-group dynamics in stressful situations, another key aspect of space exploration. The Outer Space Treaty of 1967 was even modeled after the 1959 Antarctic Treaty, establishing an agreement among nations on how to share special spaces for scientific research. While some critics have said Antarctica's conditions are too different to serve as a terrestrial stand-in for outer space, the idea of Antarctica as a practice or training ground for space exploration remains fertile ground for the imagination, both for scientists and the general public.

Antarctic meteorites offer scientists access to materials from the moon, Mars and beyond without leaving Earth. The men of the 1911–1914 Australasian Antarctic Expedition, led by geologist Douglas Mawson, collected the first meteorite discovered in Antarctica.
