Shuttle’s Human Experiments Pave Way for Moon, Mars Voyages

The space shuttle Discovery successfully finished its latest voyage today, touching down at Cape Canaveral, Florida, at 9:14 a.m. local time.

But science experiments started during the 13-day mission will continue.

Throughout their nearly two weeks in space, the crew kept diaries of their sleeping habits and filled containers with various bodily fluids.

The tasks were part of experiments designed to help better prepare astronauts to stay healthy during long-distance space flights to the moon and Mars.
