CRISM Team Closing Operations With New Global Map of Mars
Get ready to see Mars like never before.
The team behind the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument on NASA’s Mars Reconnaissance Orbiter (MRO) spacecraft released the first pieces of a new near-global map of the Martian surface on June 15 — a massive 5.6-gigapixel image in 72 colors, conveying the mineral composition of the Martian surface.
Made up of roughly 51,000 540-kilometer-long strips that together cover nearly 86% of the Martian surface, the map is the first of its kind, providing new context and a trove of data that the team expects will spawn new findings about the red planet for years to come.
“It’s effectively a whole new data set that will fuel a second wave of discoveries about Mars’ surface composition,” said Scott Murchie, a planetary scientist at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and CRISM’s principal investigator. “In fact, one of the objectives of the next MRO extended mission is for its HiRISE camera to go back and image in color the hundreds of new high-science priority spots we’re finding in the map — spots that haven’t been imaged at high resolution because their importance wasn’t known.”
