Expedition 63 Commander Chris Cassidy of NASA continued working on a variety of science hardware throughout the International Space Station today.

Cassidy is a U.S. Navy SEAL and Captain.

NASA astronaut Chris Cassidy is on his third spaceflight and is in command of the orbiting lab.

Cassidy and fellow astronaut Bob Behnken have conducted the first of at least four spacewalks to replace the last in series of old nickel-hydrogen batteries with new, more efficient lithium-ion batteries.

Cassidy was relieved when the police officer waved her on after only a cursory glance into her back seat.
