Astronaut Joseph R. Tanner, STS-82 mission specialist, is backdropped against Earth's limb and a sunburst effect in this 35mm frame exposed by astronaut Gregory J. Harbaugh, his extravehicular activity (EVA) crew mate. Harbaugh's torso is reflected in Tanner's helmet visor. The two were making their second space walk and the fourth one of five for the STS-82 crew, in order to service the Hubble Space Telescope (HST). A checklist of tasks is attached to Tanner's left arm for quick reference.
