Human-powered rover competition returns for day two

Hundreds of students from around the world gathered Saturday to attempt to drive human-powered rovers across a half-mile-long obstacle course designed to simulate the geographical terrain of the Moon, Mars and other distant bodies.

The two-day competition hosted by NASA consists of 48 teams from 16 states, the District of Columbia and Puerto Rico, as well as the countries of Bolivia, Brazil, Colombia, Dominican Republic, India, Mexico, Peru, and Singapore.
