New images captured by cameras aboard NASA's Mars rover Perseverance show several sizes of rocks scientists believe could be a sign that there was once water on the planet.
The rocks are "sharply eroded," which scientists say suggests they could have been underwater at some point.
Perseverance trekked to the South Séítah area of Jezero Crater to explore the region NASA believes could have been submerged billions of years ago.
"This area was under at least 100 meters [328 feet] of water 3.8 billion years ago," said NASA astrobiologist Kevin Hand at the Jet Propulsion Laboratory in Pasadena, California, in June. "We don't know what stories the rocks and layered outcrops will tell us, but we're excited to get started."

Experts believe the photos show evidence of the mouth of an ancient river. In addition, they hope to find proof of microbial life on Mars.
The rover, which landed on the Red Planet in February, will soon travel back to its landing spot before heading on a second mission to Jezero Crater, where scientists believe an ancient river met a lake.
