Persistence robot images confirm the existence of a lake on Mars

Robot Perseverance, who arrived Mars planet In February this year, it helped earth scientists deepen theories about the Red Planet. A study published on October 7 in the journal “Science” used images created by robots to confirm the existence of the lake.

Persistence discovered the so-called Jezero crater. The site attracted the interest of scientists from the US Space Agency (NASA) and are involved in other missions because of the ability to have life in the past. The images showed not only that the lake was present in the crater, but also that it was fed by a river.

According to the study, the existence dates back to only billions of years ago, when the Mars atmosphere flowed from it Weather across the surface of the planet.

The water content has undergone major changes over time, but it is not yet known if this was caused by floods or climate change. The lake is dry.

In addition to important confirmation for scientists, the persistence images also provided information that could help missions confirm that there was once life on Mars, albeit subtly.

Using the robot’s supercamera, it was possible to identify locations with greater potential for searching for rock and sediment fragments that may have biological components and other evidence for the existence of life.

The search for this evidence is part of Perseverance’s primary mission, which was sent to Mars in 2020. It is expected that it will collect rocky material that will be sent back to Earth, and then analyzed by scientists.

The article was first prepared with the data obtained by Persistence. Now the robot will be dedicated to searching for the remains of a delta – a rocky mass formed of sediment – that passes through a river crater.

According to mission scientists, it is believed that the base of this delta is a site with a great potential for winning rocks that may contain organic matter.
