Fifteen thousand satellites are up there and millions are planned. What that does to astronomy.
TalkScience & nature
At Geological Society of London.
A Royal Astronomical Society meeting held next door at the Geological Society, on what satellite constellations are doing to observation at every wavelength, and on the proposals ahead - orbital data centres, space-based mirrors - that would change the night sky permanently. Astronomers and regulators in one room, with the second half on what can be done. Open to anyone who buys a non-Fellow ticket. From 10:30.
