A shallow 12-inch-long trench was dug by Viking 2's surface sampler scoop on Sept. 12, 1976 on Mars.

A shallow 12-inch-long trench was dug by Viking 2's surface sampler scoop yesterday (September 12) on Mars. The trench is difficult to see in this photo because it is in the shadow of a rock (out of view to the right). The sampler scoop stopped operating sometime after soil was excavated from the trench and delivered to Viking 2 s biology instrument.
