According to the findings of the study, which were published in the journal Scientific Reports on 5 November, researchers arrived at this conclusion after examining data from the Curiosity rover, which has been studying the surface of the Red Planet since 2012. The rover specifically studied Gale Crater and its sedimentary layers. Examination of geological features is a way to travel back in time and look at how water, wind and other things affected the planet.
Curiosity noticed giant wave-shaped features in Gale Crater often called “megaripples”. According to the study, these “megaripples” are a sign that enormous floods once washed through Gale Crater on Mars’ equator.
