Speaking of razor-sharp formation flying satellites, reminder Interferometer Space Antenna (LISA) got the go ahead this year. Incredibly ambitious & cool attempt to build a much much much bigger space based version of the already 4km long Laser Interferometer Gravitational-Wave Observatory (LIGO). Requires absurdly stupensously precise formation of three satellites. https://www.esa.int/Science_Exploration/Space_Science/Capturing_the_ripples_of_spacetime_LISA_gets_go-ahead https://www.esa.int/Science_Exploration/Space_Science/Captur...
