Still Going

This Mars-based machine is a PR symbol for what man can do in science.  It is extraordinary that the rover is still working and even more so that it is performing science on a daily basis.  Everything about the robot is amazing.  It can work in the frigid temperatures of Mars without stopping.  It takes its own photographs, including selfies.  It transmits its data millions of miles to Earth through an antenna that looks absurdly small.  The machine is a work of genius that proves itself daily and is powerful PR for more such rovers to look at Mars and its once and perhaps present water.
