This cool offer from NASA has returned once again!
You can once again sign up to have your name sent to Mars on the next robotic rover. According to their FAQs, our names will fly on a future NASA mission to Mars in the mid-2020's.
Some Hiffers sent our names on the 2017 InSight rover and/or the Mars 2020 rover. According to my Galactic Law Degree, that means we already have squatters rights on Mars. I call dibs on that hill over there!
While this is cool and all, I hope to be making posts for free trips to Mars before all is said and done.
