Heliostat arrays eyed for asteroid detection during nighttime hours
A researcher at Sandia National Laboratories has proposed an innovative new use for heliostats, the large mirrors typically used to concentrate sunlight for solar power generation. John Sandusky believes these mirrors could play a key role in detecting asteroids after dark. "Heliostat fields don't have a night job. They just sit there unused," said Sandusky. "The nation has an opportunity
