A Mars Rover sent by NASA delivered the names of 11 million people on the surface of the Red Planet.
Before the space agency launched a Rover to Mars, NASA created a "Send Your Name to Mars" campaign where they collected volunteers' names.
These names are now engraved on the three nail-sized microchip and stored on the surface of Mars. NASA engineers engraved the names with an electron beam that allows them to print in tiny letters.
In addition to the names, 155 finalist essays were sent to Mars, which took part in the "Give a Name to the Rover" competition. Among the papers were the winners: Perseverance and Ingenuity. This last name was given to the experimental helicopter that accompanies the Perseverance Rover to Mars.
