From the article:

"In the last two years (2018 and 2019) — and funded purely by a few donations from friends and our own team — we have sent 4 backups to space.

    One is orbiting the Sun for at least 30 million years, in the glove compartment of Elon Musk’s red Tesla.
    One is orbiting the Earth on a satellite.
    One is now on the Moon for up to 5 billion years.
    And one was sent to space and returned to Earth and will go in a museum."
