Ep. 638: Simulating Space Missions

Ep. 638: Simulating Space Missions

Although humans have never actually been to Mars, explorers have simulated many aspects of Mars missions here on Earth. There are missions under the ocean, on the tops of volcanoes, in the harsh Canadian north, and even in bed that simulate the limitations of spaceflight, and teach us many of the lessons to prepare us for the real thing.

Ep. 637: Machine Learning in Astronomy
