NASA Perseverance rover has collected another Martian sample from its current exploration site.

The Perseverance rover drilled a core sample on Monday, filling a titanium tube with Red Planet rock for the third time.

Perseverance's third successful rock sample collection to transmit home to Earth comes after the rover's first two successful ones in September. The first two rock samples were taken from Rochette, a nickname for a particular rock. NASA’s Perseverance Rover Successfully Cores Its First Rock

This Sept. 1 image from NASA’s Perseverance rover shows a sample tube with its cored-rock contents inside. The bronze-colored outer-ring is the coring bit. The lighter-colored inner-ring is the open end of the tube, and inside is a rock core sample slightly thicker than a pencil. In a later image, the rock sample was not clearly evident inside the tube.

Perseverance Rover Collects Third Sample Containing Olivine

The Perseverance rover has taken its third rock sample on Mars. The statement was made via a tweet on the rover's official Twitter account by the rover's team.

"My latest sample is from a rock loaded with the greenish mineral olivine," the tweet reads.

Olivine, according to Space.com, is a magnesium iron silicate that makes up the majority of the Earth's upper mantle. The team behind the Perseverance rover has many hypotheses on how the olivine came up in the rock.

Olivine has been discovered in several unusual locations in space, CNet said. The material was found in craters on the massive asteroid Vesta by NASA's Dawn spacecraft. A "fingerprint" of olivine was discovered in a Martian soil sample by the Curiosity rover, investigating another region of Mars.

NASA did not further elaborate on the olivine theories floating around. Still, practically everyone should expect a lot more study as experts dig into the data. Under Percy's attentive supervision, the Jezero Crater is quietly disclosing its geologic past.

Perseverance Looks For Ancient Water Clues on Mars

The rover is presently investigating the Sétah area, where scientists believe the presence of unique rocks may reveal information about Mars' past and history of water presence.

According to Republic World, Perseverance is abrading rocks that exist in layers. This sort can only be generated in water.

These rock samples will be brought to Earth shortly when NASA sends a spacecraft to recover them from Mars.

The rock samples, according to NASA, will aid scientists in piecing together Mars' historical history and provide insight into the planet's volcanic activity and times of persistent water.

Perseverance's Rock Collection

Since then, Perseverance has roved several hundred meters and in Sétah, a rough, dune-filled section of Jezero. The location has a diverse range of multi-layered rocks, which piqued the scientists' interest sufficiently to take a sample.

"Each layer records information about the environmental conditions present when the rock formed, and changes in layer thicknesses or textural expressions indicates an environmental change," Perseverance student collaborator Erin Gibbons, of McGill University in Canada, wrote in a blog post on Nov. 12.

The first two successful rock sample harvests by the Mars rover occurred in September. Both samples were obtained from a rock known as Rochette.

After the Perseverance rover failed on its first try, it took two tries to properly obtain the first rock sample. The rock sample that was collected on the first attempt was too crumbly to study.

The next Martian rock collection occurred only a few days following the first collection's success. In its first effort, the rover got it right.
