Title
Planet Mercury
Full Description
Mariner 10's first image of Mercury acquired on March 24, 1974. During
its flight, Mariner 10's trajectory brought it behind the lighted
hemisphere of Mercury, where this image was taken, in order to acquire
important measurements with other instruments.
This picture was acquired from a distance of 3,340,000 miles (5,380,000
km) from the surface of Mercury. The diameter of Mercury (3,031 miles;
4,878 km) is about 1/3 that of Earth. Images of Mercury were acquired
in two steps, an inbound leg (images acquired before passing into
Mercury's shadow) and an outbound leg (after exiting from Mercury's
shadow). More than 2300 useful images of Mercury were taken, both
moderate resolution (3-20 km/pixel) color and high resolution (better
than 1 km/pixel) black and white coverage.
