An image has been shared hundreds of times in multiple Facebook posts that purports to show a comparison between the boot tread of a spacesuit worn by US astronaut Neil Armstrong for his 1969 mission to the Moon and a boot print he apparently left on the Moon's surface. The posts suggest the boot's tread does not "match up" with the boot print, indicating the Moon landing may have been a "hoax". The claim is false: the image shows Armstrong's preserved spacesuit at the Smithsonian Air and Space Museum, but an expert said Armstrong and fellow astronaut Buzz Aldrin wore overshoes while on the Moon's surface.
The image was posted on Facebook here. The post has been shared more than 140 times.

The photo purports to show a comparison between "Neil Armstrong's astronaut suit" (L) and "his footprints on the Moon" (R). The post goes on to claim that Armstrong's boots do not match his purported boot prints on the Moon and concludes: "Now you decide whether the moon landing was real or a hoax."
Neil Armstrong was the first man to walk on the Moon as part of the Apollo 11 mission in 1969. A summary of the mission was published here on NASA's website.
The claim is false.
The image of Neil Armstrong's astronaut suit was taken by American astronomer Phil Plait. It was featured in this article for online magazine Slate, which reports on the Smithsonian's National Air and Space Museum efforts to conserve the suit.
Below is the screenshot comparison used in the misleading Facebook posts (top) and the original images of Armstrong's spacesuit and Aldrin's boot print (bottom):
Dr Cathleen Lewis, a spacesuit expert from the US-based Smithsonian National Air and Space Museum, told AFP the boot prints and the boots featured in the misleading posts do not match because Armstrong and Aldrin wore different boots on the Moon.
"All twelve Apollo astronauts who walked on the surface of the Moon wore lunar overshoes," she said. "These oversized galoshes had blue silicone soles that left the iconic footprint in the lunar surface dust.
"They were designed to provide the Apollo astronauts with added traction in the dust. The lunar overshoes also had extra layers of white beta cloth and thin layers of insulation textiles to add further protection against unfiltered solar radiation."
This photo on the NASA website documents the Apollo 11 mission. It shows Aldrin exiting the Lunar Module with the blue silicone lined lunar overshoes mentioned by Lewis. The boot tread matches the footprint pictured in the misleading Facebook posts.
An image comparison of the photo of Buzz Aldrin exiting the Lunar Module and Aldrin's boot print can be seen below.
Lewis also explained that the image of Armstrong's suit does not include the lunar shoes because he and Aldrin left their overshoes on the Moon "due to weight considerations".
"The overshoes, Personal Life Support Systems and other equipment were considered as ballast," she said. "Every gram that they left on the surface of the Moon meant that they could bring back an additional gram of lunar samples".
