Happy Mars-iversary, Perseverance

And what a year it’s been, filled with first flights, first digs, first “breaths,” and first meltdowns (don’t worry, it’s all good now). Living up to its name so far, Perseverance keeps zooming along to fulfill its scientific duty. The mission is still one giant experiment, as NASA engineers continue to test and calibrate the sedan-sized rover and its store of instruments.
