This is Earth’s ‘twin’ planet that had water in the past and has the largest volcano in the solar system
NASA’s Perseverance rover captures striking new details of the planet, including rock samples that could return to Earth in future missions.

The solar system never ceases to amaze, especially when new discoveries are revealed – as just happened with NASA’s latest announcement about the so-called “twin” of Earth.
Capturing images of new planets or strange objects is already a challenge. Doing so with Mars, in detail, is even harder. The Perseverance rover – NASA’s mission to search for signs of life on Mars – has been sending back photographs, but dust layers and vast distances often interfere.
Despite these obstacles, NASA managed to capture a rich new image, offering fresh insights into Earth’s “twin.” In Falbreen, the most explored area of Mars by Perseverance, the rover detected flat, light-colored rocks with dark, clay-like formations, which researchers associate with great geological age.
This is Mars!

Mars, the ‘twin planet’ of Earth
One of Perseverance’s images shows Rock 43 – a five-centimeter drill sample that could one day be sent back to Earth as evidence in future missions. At the same time, the rover captured what appears to be a landscape more than 40 miles away, which NASA says humans may one day see with their own eyes.
Mars remains a planet of wonder, full of mysteries still to uncover. It is home to the largest volcano in the solar system and, although today it looks red, dry, and barren, scientists believe that long ago it may have held water – a sharp contrast to how it appears now.
