There were hugs all around at the European Space Agency on Wednesday, as news broke of the Rosetta mission's success.
Despite incredible odds, the ESA successfully landed a small robot on a comet, rushing at almost 40,000 miles per hour between Jupiter and Mars.
The agency celebrated one of the biggest space feats in years after a 10-year journey, with expected elation.
The ESA's huge success was met with champagne and cheers from the many great minds behind the decade-long project.
The Rosetta spacecraft dropped the refrigerator-sized Philae lander onto comet 67P/Churyumov-Gerasimenko, marking the first time that a robot has ever been attached to a comet.
The reaction in the Rosetta mission control room at the ESA in Darmstadt, Germany, was electric.
After ESA spacecraft operations manager Andrea Accomazzo confirmed "It has done its job; we are on the comet," cheers erupted from the packed room.

With the chance of success at just 70%, it is no surprise that the room of scientists seemed to issue a collective sigh of relief, followed by pure joy, as the announcement was made.
The emotional speech by ESA director general Jean-Jacques Dordain summed up the feeling in the room. "You know that this type of success ... it comes from hard work and from expertise. We are the first to have done that, and that will stay forever," he said.

Following the successful landing, the ESA also posted the first in a series of music videos inspired by the Rosetta mission, which features an original score by Greek composer Vangelis. Vangelis' music is often equated with science, and was recently used in the documentary series Cosmos. The following clip is entitled "Rosetta's Waltz":
