Mysterious forces and poltergeists are at work on Mars (which in due course will be found not to be so mysterious after all). But stories about moving rocks, and possible aliens are not new. The latest however is just doing the rounds based on the pictures SOL 3528 and 3540.
(Phys.org) —The lead scientist for NASA’s Mars rover exploration team (Steve Squyres) has announced that recent images beamed back by the Opportunity rover show a rock sitting in a place nearby where there wasn’t one just twelve days prior. The image, he says, has caused quite a commotion with the rover team as possible explanations for the sudden appearance of the rock are bandied about. The announcement was part of a meeting at California Institute of Technology to celebrate a decade of service by the tiny rover. ……
….. How it got there has NASA’s best scratching their heads. Thus far, they have two main likely explanations: either the rock was tossed to that spot after a meteorite impact nearby, or far more likely, it came to rest there as a result of clumsy maneuvering by Opportunity itself. The rover is having trouble getting around these days as one of its actuators has failed. This means one wheel winds up scrapping the ground during turns, producing what Squyres described as “chatter” which he said could have caused some debris to be flung to where the rock is now.
But these stories have been appearing since – at least – about 2009 (based for example on pictures SOL 1833 onwards). Moving rocks on Mars have a long history of fanciful – and some not so fanciful – notions. A whole bunch can be found here and here. But it would seem that most of the conspiracy theories and “Life on Mars” stories are connected to the selling of particular books.
As far as stories are concerned, the first ever fictional account of Mars was probably Across the Zodiac (1880) by Percy Greg. But for me, The War of the Worlds (published in 1898) by H. G. Wells and Edgar Rice Burroughs and his Martian Trilogy – published between 1912 and 1943 and which I first read in 1959 – are not easily surpassed.
