It's an opportunity for those who missed the chance to send their name on Perseverance Rover earlier.
A NASA mission to MARS is planned before end of the decade. Your name will fly on the future mission.
Registered names will be written on a Microchip. Become a Frequent Flyer to track all the missions you have participated in.
After successful registration, you get a boarding pass. You need to submit: your name, location, postal code and E-mail.
More than 20 million have already registered. There is still some time left before registration window closes.
More information is available at dedicated MARS website of National Aeronautics and Space Administration.
