The rover "perseverance" has taken a second sample from mars-rock – and has already carried out first examinations on the two samples. The rock consists of basalt and may have been formed during lava outpourings, according to the U.S. Space agency nasa.
In addition, salt minerals were discovered in the rock, which could indicate that water may have been present in this area of the planet for a long period of time – and thus that life may have been possible.
Last weekend, nasa announced that the rover had taken its first sample of mars rock and stowed it away safely. The second drilling took place a few days later. A first drilling attempt had failed in august because the rock was not solid enough and could not be filled into the sample tube. The now successfully removed and stowed sample, which is only slightly thicker than a pencil, is to be sent to earth and examined – exactly how and when is still being planned.
"Perseverance" landed on mars in a risky manover at the end of february. Development and construction of the rover, which cost around 2.5 billion dollars (about 2.2 billion euros), took eight years to complete.
