TL;DR: In this article, a new set of data obtained from direct measurements of momentum transfer to a spacecraft from individual particle impacts is presented, which can be used to detect impacts and measure properties such as the transferred momentum, direction of travel, and location of impact on the spacecraft.

TL;DR: In this article, the energy dependence of three Forbush decreases is studied and reported in the LISA Pathfinder (LPF) mission orbiting around the Lagrange point L1 at 1.5 × 106 km from Earth.

TL;DR: In this article, the authors present a new set of data obtained using a novel technique: direct measurements of momentum transfer to a spacecraft from individual particle impacts, made possible by the extreme precision of the instruments flown on the LISA Pathfinder spacecraft, a technology demonstrator for a future space-based gravitational wave observatory.

TL;DR: The main goal of the LISA Pathfinder (LPF) mission is to fully characterize the acceleration noise models and to test key technologies for future space-based gravitational-wave observatories similar to the eLISA concept, so the simplest model that efficiently explains the observations is defined.

TL;DR: The differential acceleration noise measurement presented here with the free-fall mode agrees with noise measured with the continuous actuation scheme, representing an important and independent confirmation of the LPF result.
