It’s time to update the
list of ingredients in Martian air.
In late 2012 NASA’s
Curiosity rover drew air into its onboard laboratory and analyzed Mars’s
atmospheric composition with a pair of spectrometers. The results of the
investigation, published July 19 in Science, revise decades-old data on the
makeup of Red Planet air and paint a broad picture of how the atmosphere has
changed since the planet’s formation.
