On Sept. 21, NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft will arrive in orbit around Mars and embark on a one-Earth-year long mission to collect data from the planet's upper atmosphere. MAVEN launched from Cape Canaveral, Fla. on Nov. 18, 2013 and, over the last 10 months, covered a journey of 442 million miles to get where it's going. The spacecraft is the very first to be dedicated to the study and measurement of Mars' upper atmosphere.
“The MAVEN science mission focuses on answering questions about where the water that was present on early Mars [went], about where did the carbon dioxide go,” said Bruce Jakosky, MAVEN principal investigator from the University of Colorado, Boulder's Laboratory for Atmospheric and Space Physics in a statement. “These are important questions for understanding the history of Mars, its climate, and its potential to support at least microbial life.”
MAVEN, which is equipped with a telecommunications package that allows it to relay data from the Curiosity and Opportunity Rovers currently exploring the planet's surface, is one of several efforts NASA has undertaken to prepare for potential human exploration of Mars.
