The lead scientist for NASA's Perseverance Mars rover is excited about material that has been stored in the rover's sample tubes, both dropped on the surface of Mars and contained within the rover itself while wheeling about within Jezero Crater.
Given the samples of Mars that Perseverance has collected so far, could one of those specimens be what the rover was sent to look for in the first place: evidence of past microbial life on the Red Planet?
The preliminary finding heightens the need for returning these Mars samples to Earth, so that these prized collectibles from the Red Planet can be sent to laboratories for more rigorous analysis.Related: If life exists on Mars, don't count on sample-return missions to find it, scientists say

After a steep monthslong trek, the Perseverance rover has reached the top of Jezero Crater on Mars. The site is a region unlike anything Perseverance has encountered during its 3 ½-year journey on the red planet.
Now, the robotic explorer is preparing to observe some of the oldest rocks on Mars, which could reveal the planet’s mysterious history, and potentially, whether its ancient environments were capable of supporting life. The rover is on a quest to determine if life ever existed on Mars by collecting samples that could contain ancient microfossils.
During its 3 ½-month climb, Perseverance ascended 1,640 vertical feet (500 vertical meters), acing tricky slopes angled at 20 degrees.
The ascent took place over some of the toughest terrain the rover has encountered since it landed on the crater floor in February 2021. But engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, who send commands that help the rover drive, came up with creative solutions, and the rover remains unscathed from the journey.
“They developed innovative approaches to overcome these challenges — even tried driving backward…
