The European Space Agency's (ESA) Automated Transfer Vehicle-4 (ATV-4), an unmanned cargo freighter, lifted off on an Ariane 5 rocket from Europe's spaceport in Kourou, French Guiana at 5:52 p.m. EDT (2152 GMT). The second to last of ESA's five planned station resupply spacecraft launched since 2008, ATV-4 was named "Albert Einstein" after the iconic physicist known for the theory of relativity

Einstein's theorieshave been put to the test in space and his work has guided robotic spacecraft to other planets. ATV-4 is the first spaceship to bear Einstein's name, at the suggestion of the Swiss delegation to the European Space Agency. Einstein was born in Germany but studied and spent his early career in Switzerland. [Einstein Quiz: Test Your Knowledge of the Famous Genius]
