Description:
STS-42 Earth observation taken aboard Discovery, Orbiter Vehicle (OV) 103, with an electronic still camera (ESC) is of Kamchatka Peninsula in Russia. Mid-afternoon sun projects long shadows from volcanoes on the Kamchatka Peninsula. This flat-topped volcano with the sharp summit crater is Tobachinsky, over 3,085 kilometers high. Its last major eruption was in 1975 and 1976, but it has been very active since the middle of the Sixteenth Century. The shadows cast by the low sunlight brings out the dramatic relief of the volcano as well as the smaller morphologic features. Electronic still photography is a relatively new technology that enables a camera to electronically capture and digitize an image with resolution approaching film quality. The digital images from STS-42 were stored on a disk and brought home with the flight crewmembers for processing. ESC was developed by the JSC Man-Systems Division and this mission's application of it is part of a continuing evolutionary development le
