In 1972, astronaut Charles Duke left a family portrait on the moon. Now, almost 50 years later, another NASA employee keeps its own family close.

The Perseverance rover made its monumental landing on Mars on Feb. 18 and it has already sent thousands of raw images back to Earth. Hidden in photos of the rover itself is a "bumper sticker" with icons of NASA's previous Mars rover missions, Space pointed out.

The rovers are lined up in chronological order: Sojourner, 1997; Spirit and Opportunity, 2004; Curiosity, 2012; Perseverance, 2021; and the Ingenuity helicopter, which rode along with Perseverance. NASA tweeted out a video detailing the "family portrait" plaque:
