Before his use on the Mars surface became the Perseverance-Rover extensively tested and all conceivable scenarios played through. The technicians of the NASA probably not expected.
Before pretty much a year became a not too small stone discovered, located at the left, front Rad of the Rovers has fixed. The boulder has been there for an Earth year, spinning on its wheels across the red planet’s surface.
More stones discovered
A few weeks ago a another stone spotted in front, right Rad located. This is also still there and accompanies the Perseverance Rover.
Now NASA has announced in a tweet that there is another stone in one Rover wheel fixed has, namely in right rear wheelas can be seen in images from the “Rear Right Hazard Avoidance Camera”.
Mars material on all wheels
And also on that left rear wheel is Martian rock that travels with the rover. There is a bigger stone there though not recognizable. Rather, they are smaller pebbles and something Sand.
No danger to the rover
Since the Perseverance rover curves relatively leisurely over the surface of Mars and not too much daring, jerky driving manoeuvres lies down, it is not to be expected that he will eat the small boulders, stones and sand in the near future shake off will be able to.
But that is apparently true unnecessary, as the US space agency writes in a post. Namely goes from the secret companions and stowaways no danger for the rover. Or as NASA writes in the name of the rover: “Fine by me – let’s keep rolling!“
