NASA's Maven explorer arrives at Mars after a year

In this artist concept provided by NASA, the MAVEN spacecraft approaches Mars on a mission to study its upper atmosphere. When it arrives on Sunday Sept. 21, 2014, MAVEN's 442 million mile journey from Earth will culminate with a dramatic engine burn, pulling the spacecraft into an elliptical orbit. It's designed to circle the planet, not land. (AP Photo/NASA) CAPE CANAVERAL, Fla.
