NASA’s Mars Exploration Program names nearly 11 million terrestrial people on Earth



On February 18, 2021, when the Perseverance rover landed safely on the surface of Mars inside Jezero Crater, it was also a safe landing site for nearly 11 million names on board.

How does NASA collect names?

NASA’sSend your name to Mars“The event invited people from all over the world to submit their names to follow the rover. People did it-a total of 10,932,295 names were submitted. These names are now on the surface of Mars, written on three nail-sized chips on the board Perseverance roamer.

How are the chips made?

Engineers at NASA̵

7;s Jet Propulsion Laboratory used electron beams to print the name on the chip. The “electron beam” machine they used can write very small features: less than 1 micron, much smaller than the width of a human hair. They usually use this machine for high-precision manufacturing in JPL’s Microdevices Laboratory.

In addition to nearly 11 million names, the engineers included the papers of 155 finalists in NASA’s “Named roverEssay competition. Including related “perseverance“as well as”originality“This is the name of the experimental helicopter that was brought to Mars with the rover.

Before launch, at NASA’s Kennedy Space Center in Florida, these chips were mounted on a small board that was fixed to the center of the rear cross beam on Perseverance, and the chips could be seen by a camera on the rover’s mast.

Also on the plate: a laser-etched graphic depicting the Earth and Mars connected by the sun’s rays, both of which provide light to both. In the light of the sun, what is written in Morse code is a hidden message, “Explore as one.” The illustrations pay tribute to the plaques and gold records on the pioneer spacecraft that Voyager 1 and Voyager 2 brought into space.
