NASA is following two explorers across Antarctica to get people ready for Mars

NASA is tracking two explorers on a 2,268-mile journey across Antarctica to learn more about humanity’s ability to survive on Mars. The men are braving freezing temperatures and katabatic winds up to the recorded maximum of 200 mph (320 km/h) as they make their way across the southernmost continent.

The men have been tasked with obtaining key environmental data, including ice levels, radiation and wind speed. As satellites don’t orbit directly above the pole, the measurements they take will fill in a “satellite data gap”.
