NASA’s Ingenuity Mars Helicopter recently surveyed an intriguing ridgeline near the ancient river delta in Jezero Crater.
The images – captured on April 23, during the tiny helicopter’s 27th flight – were taken at the request of the Perseverance Mars rover science team, which wanted a closer look at the sloping outcrop.

“Ingenuity not only provides imagery from an aerial perspective, but allows our team to be two places at once on Mars,” said Ken Farley of Caltech, Perseverance’s project scientist. “Sending the rover to survey and prospect in one location while launching the helicopter to survey another hundreds of meters away is a great time-saver. It can also help us explore areas the rover will never visit, as in this case.”

The ridgeline, which the science team calls “Fortun Ridge” after a parish in Norway, is a geologic feature of interest because data collected from orbit, and at a distance by Perseverance, indicates it is the boundary between the two major rock units on the crater floor.

Previous images suggest tilted layers of rock in this area of Mars are uncommon (unlike on Earth, where plate tectonics and earthquakes cause tilting). The science team will also have an opportunity to compare the Flight 27 images of this feature with data collected by both Ingenuity and Perseverance of an angled ridgeline nicknamed “Artuby” in the “South Séítah” region of the crater. Comparing Ingenuity’s shots of the two angled ridgelines may help team scientists better understand the history of the crater floor and, possibly, the forces that were at play in this part of Jezero Crater billions of years ago.

This recent science-oriented foray by Ingenuity follows scouting the helicopter performed to view the backshell and parachute that helped the Perseverance rover safely land on Mars with Ingenuity attached to its belly. Those images have the potential to help ensure safer landings for future spacecraft such as the Mars Sample Return Lander, which is part of a multimission campaign that would bring Perseverance’s samples of Martian rocks, atmosphere, and sediment back to Earth for detailed analysis.

More About Ingenuity

The Ingenuity Mars Helicopter was built by NASA’s Jet Propulsion Laboratory, which also manages the project for NASA Headquarters. It is supported by NASA’s Science Mission Directorate. NASA’s Ames Research Center in California’s Silicon Valley and NASA’s Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity’s development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Space designed and manufactured the Mars Helicopter Delivery System.

At NASA Headquarters, Dave Lavery is the program executive for the Ingenuity Mars Helicopter.

More About Perseverance

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.
