Viking sampler arm
A device used to acquire specimens of soil from the Martian surface for
use in the chemical and biological investigations carried out by the Viking
landers. The sampler could also dig trenches (which, as the lunar Surveyor
spacecraft had shown, was a valuable way of learning about the surface)
and provide other data about the physical properties of the surface materials
using a temperature sensor, brush, and magnets. It consisted of a head attached
to the end of a 3-m retractable boom.
