STS104-E-5238 (21 July 2001) --- Astronaut Michael L. Gernhardt, STS-104 mission specialist, was photographed with a digital still camera during extravehicular activity (EVA) with the International Space Station (ISS). During this, the third, STS-104 space walk, Gernhardt and astronaut James F. Reilly attached a nitrogen supply tank to the Airlock Quest's shell and also moved hand-over-hand up the station's solar array truss to take a look at a gimbal assembly mechanism that allows the arrays to swivel with the Sun. This space walk was the first ever that has utilized the new airlock.
