As a consolation prize for the rest of us, NASA is offering to fly your name-etched onto a microchip-on the Mars 2020 rover.
When NASA's InSight mission lifted off in May 2018, it was carrying more than two million names on microchips, giving each "flyer" about 300 million frequent flyer miles, or almost 500 million frequent flyer kilometers. Using an electron beam, the names will be etched on a silicon chip with text smaller than one-thousandth the width of a human hair.
The names will be dispatched with the Mars 2020 rover, which is now under construction.
The Mars 2020 Project at JPL manages rover development for NASA's Science Mission Directorate.
You could join the trip too, by sending your name to ride along with the rover.
The 1,000-kg rover would search for signs of past microbial life, characterize the planet's climate and geology, collect samples for future return to Earth, and pave the way for human exploration of the Red Planet.
Space fans can register onliine to be added onto a chip sent up into space on the Mars 2020 rover. The agency also added that the main goal of this rover is to "search for signs of past microbial life, characterize the planet's climate and geology, collect samples for a future return to Earth, and pave the way for human exploration of the Red Planet".
People will receive their own souvenir boarding pass and "frequent flyer" points.
Kilometers are awarded for each "flight", with corresponding digital mission patches available for download.
NASA may not be ready to take passengers to Mars, but you'll be able to put your name down in the meantime - quite literally. The Mars 2020 spacecraft, which will carry the rover during its seven-month-long trip from Earth to its destination, is almost ready for time in the spotlight, but there's still some work to be done before a launch date can be solidified.
