Here's a chance to witness a world first: the European Space Agency (ESA)'s Rosetta spacecraft is scheduled to meet the 67P/Churyumov-Gerasimenko comet today at 4AM ET.
Launched in March 2004, Rosetta completed several fly-bys of Earth and Mars and imaged two asteroids before entering hibernation in June 2011. It was awaken from its slumber on Jan. 20, 2014, to finally fulfill its destiny: a rendezvous with a comet, the first human-made spacecraft to do so.

If everything goes according to plan, Rosetta will escort the comet during its orbit around the sun and deploy a lander to its surface.
