First ever space-to-Earth solar power mission succeeds
Scientists say success of test will ‘help chart the future of space solar power’
“Solar power beamed from space at commercial rates, lighting the globe, is still a future prospect,” said Caltech president and professor of physics Thomas Rosenbaum. Space-based solar arrays that beam massive amounts of clean and renewable energy to Earth via microwaves were first conceived more than 50 years ago, with scientists noting that such setups are not limited by cloud cover or the Sun’s cycle. “The space test has demonstrated the robustness of the basic concept, which has allowed us to achieve a successful deployment in spite of two anomalies,” said Sergio Pellegrino, a professor of aerospace and civil engineering at Caltech.
