A woman named "Jackie," who claims to be a former NASA employee, called Coast to Coast AM in the U.S. She claimed she had seen evidence of two human figures walking towards the Viking lander on Mars in 1979.

A color mosaic taken by NASA's Mars Curiosity rover Mast Camera (mastcam) shows strata exposed along the margins of the valleys in the "Pahrump Hills" region on Mars in this undated handout photo courtesy of NASA. After 18 months of driving, scientists on September 11, 2014, announced that Curiosity had arrived at the base of Mount Sharp ahead of schedule, thanks to a somewhat serendipitous decision to take an alternative path that would be gentler on the rover's damaged wheels. Within two weeks, Curiosity will reach an outcrop of rock called Pahrump Hills, where the first drill samples of Mount Sharp real estate will be made.

The "former NASA employee" asked the radio show presenter to solve a 27-year-old mystery for her. She claimed she had worked for NASA and that her job was to handle the downlink telemetry from the lander. The Viking lander was the first vehicle to send back pictures of the surface of the Red Planet.

She said that while she was working, she saw two people walking across the Martian surface. She continued that she and six colleagues were watching the footage of the Viking rover moving around on multiple screens when she noticed two men in spacesuits walking to the Viking Explorer from the horizon. She added the men's suits looked protective but unlike what astronauts wore.

The "former NASA employee" said she and her colleagues were maintaining the equipment when suddenly the video feed got cut off. She went on to say that when they ran upstairs, they found the door was locked and paper was taped over the door so nothing could be seen. She posed a question to the radio presenter asking whether or not the two men she saw were guys from NASA. The agency has yet to comment on the claim.

Blogs that report on UFO and conspiracy theories have backed the "former NASA employee." They claimed humans had been on Mars to polish off the lander's solar panels. Metro.co.uk wrote that this seemed off because if the humans were there, they could have filled petrol into the lander or take photos themselves. A few other conspiracy theorists claimed that in the sixties, there were secret landings on Mars. They further claimed that the Apollo landings were a cover-up for wider exploration of the solar system.

An audio recording, titled "NASA Worker Sees Men Walking Over To Viking Lander On Mars", was posted on YouTube by YouTube channel Starman Chronicles. The video has managed to get more than 11,000 views and about 16 comments as of this writing. Listen to the audio recording below:
