“My battery is low
and it’s getting dark.” Weep
for my silent voice.
Opportunity,
roved beyond expectation.

Today, the Mars Rover Opportunity has been declared dead. It was meant to function for 90 days, and instead, worked for 15 years and sent amazing data about Mars’s hydrography. It was recently caught in a dust storm that covered its solar panels. In some future time, will someone clean the dust off this strange relic, and Opportunity will call to NASA again? Until then, Sleep well, Opportunity. More info here.

Oh, I like this poem. Sounds like any one of us on a low energy day, but I adore the ode to Opportunity.
