​NASA’s Perseverance rover will leave small titanium tubes on the surface of Mars containing a variety of soil and rock samples from the planet Rotia, which will be recovered by the mission, which will last more than a decade.

Over the next 30 days, the rover will leave ten titanium sample tubes in a flatter area of ​​Jezero Crater called Three Forks.

Over the past 16 months, Perseverance has drilled into the Martian surface several times and collected several types of Martian rock and dust into dozens of tiny, perfectly sealed titanium tubes, tubes it will leave on the Martian soil starting Monday. One of the tubes also contains a sample of Martian air.

These tubes are to be picked up in a few years by another mission, which in a series of complicated steps will bring them to Earth, where they will be analyzed in the best laboratories. This mission consists of several stages, and the stones will reach Earth after 2030.

A few billion years ago, there was a lake and possibly a delta in the Jezero crater. Scientists hope the site will provide evidence that simple life forms may have existed on early Mars.

Perseverance collected 18 sample tubes.

The Perseverance rover is searching for signs of life on Mars, and Lake Crater is an extremely attractive site because it is believed to have been a lake and delta of liquid water more than three billion years ago.

Differences between Mars and Earth

  • The diameter of Mars is half the diameter of the Earth
  • The atmosphere is very rarefied, and atmospheric pressure is less than 1% of Earth’s
  • Mars receives more than 70 times more cosmic radiation.
  • Mars does not have a global magnetic field, but it is very weak, which does not protect the planet from cosmic radiation
  • There are no oceans, rivers or lakes on Mars, and water is only found in the form of ice, either on the polar caps or buried under the surface
  • Mars does not have plate tectonics.
  • On the Red Planet, the temperature rarely exceeds +20 degrees, and this is at the equator, and at the poles it can be -120 degrees.
