In January, suddenly appeared in front of the Mars Rover “Opportunity” a stone in the shape of a donut on. Nasa needed more than a month to deliver the obvious explanation for the phenomenon.
The Mars Donut had seemingly materialized out of nowhere: An approximately four inches large stone which had roughly the shape of the sweet pastry, lay on 8 January suddenly on the planet’s surface next to the Nasa rover “Opportunity”.
One of the six wheels of the robot had pushed the stone into view of the camera. Twelve days earlier at the same location but nothing yet located, such as images revealed.
The pictures of the strange chunk subsequently conducted worldwide to guesswork. Now, the U.S. space agency has solved the mystery. And the explanation is somewhat sobering: The Rover “opportuniy” even had the “donut” separated by a boulder

The stone was “Pinnacle Iceland” baptized
According to NASA information came officially “Pinnacle Iceland” said Stein – the outside is white and dark red inside -. chunks of a similar nearby
After “Opportunity” was set back a bit, be above the locality a converted stone ejected been seen “by the same unusual phenomenon,” said Ray Arvidson of Washington University in St. Louis (U.S. state of Missouri), participates in the “Opportunity” program. “We are driven over it., We can see the track.”
The explanation for the emergence of “Pinnacle Iceland” is thus rather profane. However, the stone is unusual: The spectrometer of “Opportunity” have “a high level of manganese and sulfur” measured, said the Nasa

water created this special stone
The water-soluble components seemed to indicate “that they were concentrated in the stone by the activity of water.” 2013 had been the Mars rover “Curiosity” found a remarkably high proportion of water in soil samples.
And Robots “Opportunity”? The rolls for the solution of the donut mystery continues to explore the surface of Mars. The ten years since he’s doing – and for four years alone: ??his “twin brother”, the rover “Spirit”, had already given up the ghost in 2010
