What do you mean by tickets to Mars?

Mars ticket is a certificate that brings your name to Mars. It originated from a public activity sponsored by NASA. The American Mars spacecraft Insight will store the names of fans in a small chip, bring Mars with them, and fans will also receive boarding passes from Insight.

Mars tickets

As early as 20 16, NASA invited space fans to apply for insight boarding pass in NASA official website.

Fans who apply successfully will store their names in a small chip and take them to Mars by Insight. In this special way, fans can realize their dream of "space travel".

"Insight" was originally scheduled to be launched in March 20 16, but it was delayed for some reason and finally successfully launched on May 5, 20 18. After nearly seven months of interstellar flight, Insight has brought more than 2.4 million fan names to Mars.
