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: Electrostatic measurements made on board the European Space Agency mission LISA Pathfinder are the first made in a relevant environment for a space-based gravitational wave detector and resolve the stochastic nature of the TM charge buildup due to interplanetary cosmic rays and theTM charge-to-force coupling through stray electric fields in the sensor.

TL;DR: The LISA Pathfinder (LPF) mission as discussed by the authors is the first in-flight test of low frequency gravitational wave detection metrology, which was designed to simulate one arm of space-borne gravitational wave detectors by shrinking the million kilometer scale arm lengths down to a few tens of centimeters.

TL;DR: In this article, the performance of the capacitive gap-sensing system of the Gravitational Reference Sensor on board the LISA Pathfinder spacecraft was reported, with a performance of up to 1mHz.

TL;DR: In this paper, the authors report on the temperature measurements throughout mission operations, characterize the thermal environment, estimate transfer functions between different locations, and report temperature stability (and its time evolution) at frequencies as low as 10'|$\mu$|Hz, where typically values around 1'K'Hz^−1'1/2 were measured.
