The “perseverance” of NASA Rover has made a fascinating find on Mars: a stone that is covered with hundreds of millimeters balls. However, the find is a great mystery for the investigation: now it must be investigated how these strange structures originated.
Two weeks ago, “perseverance” reached a region called “Broom Point” on the edge of the Jezero crater, where visible light and dark rock strokes had to be investigated. When investigating a clear rocket, De Rover noted a striking stone that baptized the “St. Paul’s Bay” team.
So far, so unusual: but the stone is littered with spherical structures, some of which are elliptical or angular and even have small holes. Alex Jones from Imperial College in London described her in his blog post for NASA as “shocking balls”.
Reminder of “Mars blueberries”
Such spherical forms are not unknown on Mars: in 2004 the Rover “Opportunity” discovered so-called “Mars Bosberries”, and “Curiosity” also found similar structures in the Gale crater. Finally, “perseverance” observed popcorn-like formations in the Jezero crater. Science is based on earlier finds that these balls were created by the circulation of groundwater.
Volcano, impact with meteorite or water?
There are various possible explanations for the formation of the balls: they may have been created by cooling melted rock after a volcanic eruption or by condensed rock vapor due to a meteorite attack. Each of these theories would offer important information about the geological history of Mars.
“Floating Stone” is loose on the surface
The research is particularly difficult because “St. Pauls Bay” is a so -man -fitting “floating stone” – it is loose on the surface and probably comes from another geological layer. The first analyzes indicate that the stone could be one of the dark layers that the research team has already identified from a job.
Search for the past life
The Mars Rover “Perseverance” landed in the Jezero -Krater, a region that once housed a more in February 2021. The mission is to find traces of the previous life and to collect geological rehearsals that must be brought to earth in the future. The discovery of the spherical stone could now offer new knowledge about the climatic and geological development of the red planet.
The scientists are therefore already working on deciphering the exact origin and rise of the mysterious balls and possible to resolve another piece of the Mars puzzle.
