If the Philae space mission continues to go as well as its daring landing did just minutes ago, the little lander that could will begin capturing images of comet 67P/Churyumov-Gerasimenko's terrain. Though its harpoons didn't fire just yet for some reason, the plan is for the craft to then gather surface samples and analyze the comet's chemical composition.
Scientists hope the materials on the comet's surface will help us understand more about how our Solar System came into existence over 4.5 billion years ago.
One theory about the history of space is that comets like this one delivered water to the planets, including ours.
And therein lies one possible true hidden reason for Philae's 316-million-mile trip: To get a drink.
