Gravitational wave testbed repurposed as comet dust detector
In the final months of Europe’s LISA Pathfinder mission, scientists have found an unexpected use for the trailblazing testbed for a future gravitational wave observatory by tracking the tiny dings made by microscopic particles that strike the spacecraft in deep space, exploiting the impacts to learn about the population of dust grains cast off by…
