TL;DR: The first results of the LISA Pathfinder in-flight experiment demonstrate that two free-falling reference test masses, such as those needed for a space-based gravitational wave observatory like LISA, can be put in free fall with a relative acceleration noise with a square root of the power spectral density.

TL;DR: The LISA Pathfinder satellite was launched on 3 December 2015 toward the Sun Earth first Lagrangian point (L1) where the LISA Technology Package (LTP), which is the main science payload, will be tested.

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: The LISA Pathfinder mission will demonstrate the technology of drag-free test masses for use as inertial references in future space-based gravitational wave detectors as discussed by the authors, and the Pathfinder spacecraft will perform drag free flight about a test mass while measuring the acceleration of this primary test mass relative to a second reference test mass.

TL;DR: In this article, the authors present an overview of recent activities, focusing on the improvements in the modelling of the instrument and in the data analysis campaigns performed both with real and simulated data.
