Does this NASA image show a ‘gateway’ and ‘wall’ on Mars?

An image taken by NASA’s Mars Curiosity Rover on May 7, 2022 shows “a gate and a nearby wall that appears artificial.”


While the image in question was an original image captured by a camera aboard NASA’s Curiosity spacecraft on May 7, 2022, the agency’s Jet Propulsion Laboratory told Snopes that what some social media users had interpreted as a “gateway and wall,” was actually a rocky fissure on the red planet.

A popular May 2022 post on Reddit claimed that NASA’s Mars is Curiosity roaming Take a picture of a so-called “gateway” and a “nearby seemingly artificial wall” on the Red Planet that was as suspicious as it sounded.

It was because while something was being filmed in the grainy black and white version of take photo The image captured by the rover’s camera can be interpreted as resembling the shape of a door, as the agency’s Jet Propulsion Laboratory (JPL) told Snopes that it was actually “a very, very magnified shot of a small crack in a rock.”

“The team’s scientists emphasized how small it is [the crevice] IS: About 30 cm wide by 45 cm wide (11 by 17 in), a JPL spokesperson said via email. “They said there are linear fractures throughout this bump, and this is where many linear fractures occur. “

The picture was taken with the mast camera (mastic) on board the Curiosity rover, a system that uses a fixed focal length, multispectral imaging instrumentation to take “true color” images of the red planet and beyond. The image of “The Door” was taken on May 7, 2022, which is also Sol 3466 – the 3466th solar day on Mars, or Mars day.

The NASA media relations team also referred us to a publicly available digital file mosaic Also from the photos taken by the rover. The piece was created by Neville Thompson, who is not affiliated with NASA, which showed the contents of the image in question within the wider Martian interior.

The small “door” (slit) can be seen nearly dead center, a little higher, and a little bit to the left.

“Look? You can zoom in with +/- on the right side of the screen. It’s very small and looks like…a crevice in the rock,” the speaker wrote.

While we can’t say for sure if Martians actually used small doors, NASA was certain that the “door” in this case was just a small rocky crevice. So, while Reddit showed an original image taken by NASA’s Mars Curiosity rover, the image didn’t show an artificial gate or wall. As such, we have categorized this claim as “false”.
