LISA Pathfinder has also achieved the most sensitive measurements of the perturbation to the freefall motion of the test masses caused by cosmic rays – electrically charged particles, like protons or electrons – that flow across our Galaxy. This result, published in April 2017 in Physical Review Letters, will be important not only for a future gravitational-wave observatory but also for other space-based experiments testing gravity and fundamental physics
