LISA THE '867 ),1'(5

The LISA Pathfinder probe is being repurposed to study space dust. The satellite was designed to test the technology necessary for a spacebased gravitational wave detector, and so is incredibly sensitive to minute forces, such the tiny push of a micrometeoroid impacting its surface. Its detector will be able to track and monitor the dust, helping to refine micrometeoroid models, which will be used to reduce the risk of dust damaging current and future spacecraft.
