A photo taken by NASA's Curiosity rover on Mars shows an opening in a rock face that looks like a door. But this is not a secret nose for Martians! Ashwin Vasavada, who is part of the Mars Science Laboratory project, said to Gizmodo: "It's just the space between two fractures in a rock."
The photo of the door was taken on May 7 by Curiosity's Mastcam as it ascended Mount Sharp. The crack in the rock is about a foot high, and is located in a desolate landscape, where the rock of the wall where the crack opens meets the desert: a typically Martian landscape.
What you see in the photo would actually seem to be an opening at the base of an artificial rock face. On the web, of course, speculations started immediately but also funny mames.
Mars Science Laboratory
Mars Science Laboratory is a NASA exploration mission of the planet Mars.
The mission is mainly made up of the activities of the rover named Curiosity, which was launched on November 26, 2011 and landed on Mars on August 6, 2012. Immediately after landing, successfully carried out using the EDL method, more precise than the missions previously sent to the planet, the rover began sending images from the surface.
The duration of the mission was expected to be at least one Martian year but is still ongoing with the aim of investigating the past and present ability of Mars to sustain life. Curiosity carries scientific instruments, supplied by the international community, more advanced than those of any previous mission to the red planet.
On July 22, 2011, NASA announced the area to which the probe would be sent: the Gale crater. The launch then took place in November of the same year by means of an Atlas V vector, and Curiosity finally landed successfully on Mars on August 6, 2012 at 5:14:39 UTC, 7:14:39 Italian time, 8 months after.
During its activity on Mars, the robot will analyze dozens of soil and rock samples. The rover has two pairs of black and white cameras located at the four corners of the rover, similar to those found on the MER rovers. They are used to avoid obstacles during automatic driving and to safely position the robotic arm on the surface and rocks.
The cameras have an angle of view of 120 ° and map the terrain up to 3 m from the rover thanks to stereoscopic vision. Navigation cameras are a pair of black and white cameras mounted on the robotic arm to support ground movement.
They have a 45 ° angle of view and use visible light to reconstruct the stereoscopic 3D image in front of the camera.
