Mars Exploration Rovers Launched
News story originally written on July 10, 2003

The Mars Exploration Rovers (MER) mission is now underway. Twin robotic vehicles bound for Mars were successfully launched from Cape Canaveral in Florida. The rovers, which will explore the geology of Mars in search of signs of water, are scheduled to land on Mars in January 2004.

The first MER spacecraft, named Spirit, blasted off on June 10, 2003. It is slated to land within Gusev Crater on Mars. The second MER, called Opportunity, lifted off July 7, 2003. It will explore the Meridiani Planum region of The Red Planet. Both spacecraft rode into space atop Boeing Delta II launch vehicles.
