Dark Sky, Bright Sun
Title Dark Sky, Bright Sun
Explanation In low Earth orbit there is not enough atmosphere [ http://liftoff.msfc.nasa.gov/academy/space/atmosphere.html ] to diffuse and scatter sunlight, so shadows are black and the sky is dark [ http://webexhibits.org/causesofcolor/14.html ] - even when the Sun shines. The harsh lighting produced this dramatic effect [ http://antwrp.gsfc.nasa.gov/apod/ap030315.html ] as mission specialist Gregory Harbaugh photographed colleague Joseph Tanner during their second spacewalk to service the Hubble [ http://antwrp.gsfc.nasa.gov/apod/ap970221.html ] Space Telescope in February 1997. The aft section of the Space Shuttle Discovery [ http://antwrp.gsfc.nasa.gov/apod/ap020126.html ] is visible in the background with the Sun hanging over a delicate crescent of the Earth's limb [ http://antwrp.gsfc.nasa.gov/apod/ap030424.html ]. A checklist is attached to Tanner's left arm, and Harbaugh's reflection is [ http://mirrorproject.com/galleries/gantz/ ] just visible in Tanner's visor.
