NASA's New Horizons flew by Pluto in 2015. It finished its transmission earlier this week.
We have our pot of gold.
It took more than five hours for New Horizon's last photo to make the 3 billion-mile journey to Earth. Now it's heading for the Kuiper Belt, a region of icy comets and asteroids at the edge of our solar system. It should arrive by 2019.
Who knows when the next data from a spacecraft visiting Pluto will be sent?
All told, more than 50 gigabits of data were sent over New Horizons' 15-month journey. And it might be a long time until a similar mission is launched.
