Moonwalking

A new study indicates astronauts should be able to walk faster on low gravity worlds like the Moon, Mars, and asteroids, than previously thought, thus making exploration of those worlds more efficient.

The study is part of an effort to build spacesuits that allow more mobility.  Apollo astronauts tended to hop on the Moon because spacesuit designers of that era were more concerned with safety than mobility, and moving the legs to walk was more difficult than hopping in the light lunar gravity.
