The Rosetta Spacecraft has finally caught up with the Comet 67P/Churyumov-Gerasimenko, the comet it has been chasing for over a decade.
Jean-Jacques Dordain, Director General of the European Space Agency (ESA), was ecstatic to announce to the public they finally made it.
Rosetta travelled 6.4 billion kilometers over the past 10 years, five months and four days. In the course of its chase, the spacecraft looped around the Sun five times.

Dordain is happy to announce that Rosetta is now officially the first spacecraft in history to rendezvous with a comet.
With Rosetta, scientists can finally explore the origin of humans because comets are considered to be the primitive building blocks of the Solar System.
Researchers said that as Rosetta approaches closer to the comet, it will reveal the comet's "personality."
The comet's coma, an extended envelope of gas and dust, became rapidly brighter and died down for six weeks.
The images of the comet taken from a distance of 12,000 km reveal that the nucleus has two distinct segments joined by a neck, making the comet look like a duck.
Matt Taylor, one of the ESA scientist involved in this exploration, said their first clear view of the comet gave them plenty to think about.
He said that the comet's appearance has yet to be defined, but they are already wondering if its appearance came from two separate comets that merged.
They also wonder if the comet is just one comet that has dramatically eroded and become symmetrical over time.
Taylor said that over the next few months they will begin the final preparation to land the probe, Philae, on the comet.
He stressed that Rosetta will continue to accompany the comet after landing until it approaches the Sun in August 2015.
To date, Rosetta is 100 km from the surface of the comet. Researchers said Rosetta will still edge closer to the comet.
