MAVEN launch
According to NASA, MAVEN, weighing 5,410 pounds, will take 10 months to
reach Mars' atmosphere and is expected to begin orbiting the planet on Sept.
22, 2014. During the mission, MAVEN will examine all of Mars' latitudes and
will perform five deep dip maneuvers, descending to an altitude of 78 miles
above Mars' surface. This will mark the lower boundary of the planet's upper
atmosphere. (Photo by Pat Corkery, ULA)
