The Rosetta spacecraft followed a 10-year mission to catch a comet and land a probe on it. Launched in 2004, the spacecraft arrived at its target, Comet 67P/Churyumov-Gerasimenko, on Aug. 6, 2014.

The two-part Rosetta spacecraft is designed to orbit and land on the Comet 67P/Churyumov-Gerasimenko in November 2014. See how the Rosetta spacecraft works in this Space.com infographic.

The Rosetta mission will reach its climax on Wednesday when scientists attempt to land a spacecraft on a moving comet. Here’s why we should all be excited.

For a billion miles, the tireless spacecraft called Rosetta has shadowed an icy comet through the solar system, enduring dust storms, fountains of gas and the comet’s mood swings.

Then, at 1:18 p.m., huge antennas in NASA's Deep Space Network picked up Rosetta's broadcast, prompting wild applause and raucous cheers at the Rosetta control center in Darmstadt, Germany.
