The next mission to the Red Planet, the Mars Atmosphere and Volatile Evolution (MAVEN) will be the first spacecraft ever to make direct measurements of the Martian atmosphere. MAVEN will carry eight science instruments, including a magnetometer that will investigate what remains of Mars’ magnetic “shield,” and will, in essence, help to look back in time at what may have happened to a planet once thought to have an abundance of liquid water but is now a frozen desert. The magnetometer will play a key role in studying the planet’s atmosphere and interactions with solar wind, helping answer the question of why Mars lost much of its atmosphere.
“The magnetometer helps us see where the atmosphere is protected by mini-magnetospheres and where it’s open to solar wind,” said Jack Connerney, a co-investigator for the mission. “We can study the solar wind impact and how efficient it is at stripping the atmosphere.”
