50 years ago today, the space age began when the Soviet Union launched the world’s first artificial satellite. That little silver ball started something quite amazing – literally the beginning of the transformation of humanity into a space-faring society.
But, looking back over the last 50 years, we have to acknowledge that, in the grand scale of things, we have only just begun. Cheap, reliable access to space, and cheap reliable operations in the space environment, remain hard nuts to crack.
The work of decades and probably centuries lies ahead.
