A member of the Perseverance rover’s science team explains why the aerial image offers science advantages over ground-level images.
Ask any space explorer, and they’ll have a favorite photo or two from their mission. For Kevin Hand, a scientist at NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is “To discover and expand knowledge for the benefit of humanity.””>NASA’s Jet Propulsion Laboratory in Southern California and co-lead of the Perseverance rover’s first science campaign, his latest favorite is a 3D image of low-lying wrinkles in the surface of Jezero Crater. The science team calls this area “Raised Ridges.” NASA’s Ingenuity MarsMars is the second smallest planet in our solar system and the fourth planet from the sun. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.”>Mars Helicopter captured the two shots for this stereo image on July 24 during its 10th flight.
“Ingenuity is allowing the Perseverance science team to be in two places at once,” said Hand. “Right now, we are at the ‘Crater Floor Fractured Rough,’ where the rover is preparing for the mission’s first sample acquisition on Mars. Yet at the same time, Ingenuity is providing a detailed preview of a potentially intriguing geologic features hundreds of meters away from us.”
The Raised Ridges intrigue Hand and his colleagues because they consist of three distinct surface fractures that converge at a central point. On Earth, similar fractures in desert environments might be a clue to past liquid water activity and thus past habitability. The Perseverance science team wants to know if what is good for the third rock from the Sun is good for Mars – and if so, whether the Raised Ridges tell them something significant about Mars’ watery past.

“In 3D it almost feels like you can reach out and touch the Raised Ridges,” said Hand. “But along with its immersive beauty, the image provides great detail. If you look closely, you can see some curious lines across the surfaces of several rocks. Are these just made by eons of wind and dust blowing over the rocks, or might those features tell the story of water? We just don’t know yet.”
Those details are important. In their search for signs of ancient life on Mars, the team is considering drilling a rock or sediment sample in the Raised Ridges, which would take several Martian days, or sols, of driving to reach. With Ingenuity’s images, the rover team now has a much better idea of what to expect if they were to go there and the science value of doing so. In the weeks to come, the science team will pour over this and other 3D images from Ingenuity and debate the merits of such a visit.
“Since landing at Jezero Crater, it’s clear to all of us that there is an abundance of geologic riches for us to explore. It’s a good problem to have,” said Ken Williford, deputy project scientist for Perseverance at JPLThe Jet Propulsion Laboratory (JPL) is a federally funded research and development center managed for NASA by the California Institute of Technology (Caltech). The laboratory’s primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA’s Deep Space Network. JPL implements programs in planetary exploration, Earth science, space-based astronomy and technology development, while applying its capabilities to technical and scientific problems of national significance.”>JPL. “These aerial previews from Ingenuity provide the kind of actionable data that allow us to whittle down our options and get on with the business of exploring our corner of Mars.”
More About the Mission
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
