NASA scientists might have been yodeling for joy in March when they saw the first-ever picture of active landslides occurring on Mars.
Snapped by the Mars-orbiting HiRISE camera, billowing clouds of dust revealed the action at the base of a towering slope near the red planet's north pole.
"It's great to see something so dynamic on Mars," HiRISE team member Ingrid Daubar Spitale noted at the time. "A lot of what we see there hasn't changed for millions of years."
