Robotic 'Light Bender' on the moon could help Artemis astronauts keep the lights on

The concept of redirecting sunlight into dark areas has already been used on Earth! The Norwegian town of Rjukan sits in a deep valley and given its Northern latitude sits in shade for half of the year. High on the mountain opposite, 450 metres above the town, three large, solar-powered, computer-controlled mirrors steadily track the movement of the sun across the sky, reflecting its rays down on to the square and bathing it in bright sunlight. Rjukan – or at least, a small but vital part of Rjukan – is no longer stuck where the sun don't shine.
