The Mars Science Laboratory, or Curiosity, will land on the surface of Mars in August 2012. Curiosity

is being assembled and readied for a November launch at NASA's Kennedy Space Center in Florida.

Curiosity is about twice as long and more than five times as heavy as any previous Mars rover.

The rover will study whether the landing region had environmental conditions favorable for supporting

microbial life and for preserving clues about whether life existed.

July 22 is Mars Day at the National Air and Space Museum. The annual event marks the July 20, 1976

landing of Viking 1, the first spacecraft to operate on Mars. The day will feature displays, family

activities and presentations by scientists from the museum's Center for Earth and Planetary Studies, the

Museum of Natural History and NASA. Visitors will learn about the latest Mars research, missions and

see a life-size model of Curiosity.
