Ingenuity's View of Sand Going Into Conjunction

NASA's Ingenuity helicopter captured this view on Nov. 3, 2023, of its parking spot during Mars solar conjunction – a period when the Sun is between Earth and Mars, limiting communications. Ingenuity will use its color camera during this period to take time-lapse images of sand grains to learn more about how they move on the Red Planet. In the upper left of the image, one of the helicopter's legs is visible just out of frame. Just to the right of that is one of several "footprints" made before the helicopter lifted off on a previous flight to reposition itself. During conjunction, hot, ionized gas being expelled from the Sun's corona can potentially corrupt radio signals sent from Earth to NASA's fleet of Mars spacecraft, leading to unexpected behaviors. So, during this time, engineers don't send any commands, but the spacecraft do send their health data back to Earth. After conjunction, scientists will look through Ingenuity's imagery and see if any sand grains were blown by the wind. They plan to correlate this imagery with weather data collected by NASA's Perseverance rover, which is parked 3,471 feet (1,058 meters) away during conjunction. Wind and sand are major drivers of change on the Martian landscape, and scientists hope they will better understand these processes by studying the wind strength needed to lift sand particles. https://photojournal.jpl.nasa.gov/catalog/PIA26050
