The following article reports "Experts estimate there are now 15,694lbs (7,119kg) of human debris on the surface" on Mars.
Is that what explains the following?
The protrusions are thought to be 'sand spikes', but scientists have not ruled out that they might have come from an alien spaceship
In April, Nasa’s Curiosity Rover photographed what appear to be rows of spikes, plates and wedges protruding from rocks on the floor of the 96-mile (154 km) Gale Crater.
At the time, astrobiologist Dr Nathalie Cabrol, of the Nasa Ames Research Centre and Search for Extraterrestrial Intelligence (Seti) Institute, said it was “the most bizarre rock” she had ever seen in 20 years of studying Mars.
Now, a new paper published in the Journal of Astrobiology concludes that the formations might be “sand spikes”, similar to those known to form on Earth in water-logged sands during strong earthquakes of magnitude seven and greater.
Similar rock formations have been found at the north Alpine basin of south Germany, associated with the 15 million year old Nordlinger Reis asteroid impact basin, and at Mount Signal in the Imperial valley of southern California, close to the San Andreas fault.
But researchers caution that “a fragment from an extraterrestrial or terrestrial spacecraft cannot be discounted with absolute certainty” – pointing out that what appear to be wheels, an axle and a debris field have been photographed in another part of the Gale Crater. ...
But he added: “Any debris field on Mars would certainly suffer erosion over time, especially from wind.”
In the images taken by Curiosity, at least six rocks are shown with strange protrusions, including one with 11 evenly spaced spikes.
Wedge-shaped objects resembling shark teeth can also be seen below the spikes, as well as plates or boards that appear to have embedded spikes.
Many suggested that they could be the remnants of a crashed Mars orbiter or discarded equipment.
Pieces of landing modules, such as heat shields or parachutes, are often jettisoned on the way down to the surface. They can break into smaller pieces and be blown around by Martian winds.
At least 10 spacecraft have crashed or lost contact on Mars, including Britain’s Beagle 2.
Even bits of the Curiosity Rover have fallen off as it has trundled over the Red Planet. Experts estimate there are now 15,694lbs (7,119kg) of human debris on the surface.
But, in the new paper, experts say it is unlikely the strange objects were linked to human craft because they do not look like anything sent from Earth. ...

Alien spaceship ‘could have crash-landed on Mars’

Objects ‘unlikely to be from human craft’
Previously, it was speculated that the strange objects were fossil fish bones, dinosaur bones, or caused by weathering through Martian winds.Many suggested that they could be the remnants of a crashed Mars orbiter or discarded equipment.

Alien spaceship ‘could have crash-landed on Mars’
An alien spaceship crash landing cannot be ruled out as the cause of the strange pointy protrusions found on Mars, scientists have said.
