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 spacetime explorer and quantum equivalence principle space test satellite mission, proposed as a medium-size mission within the Cosmic Vision program of the European Space Agency (ESA), aims for testing general relativity with high precision in two experiments by performing a measurement of the gravitational redshift of the Sun and the Moon by comparing terrestrial clocks, and by performing the universality of free fall of matter waves in the gravitational field of Earth comparing the trajectory of two Bose-Einstein condensates of 85Rb and 87Rb as mentioned in this paper.

TL;DR: The STE-QUEST satellite mission as mentioned in this paper is a medium-size mission within the Cosmic Vision program of the European Space Agency (ESA), which aims to test general relativity with high precision in two experiments by performing a measurement of the gravitational redshift of the Sun and the Moon by comparing terrestrial clocks, and by comparing the trajectories of two Bose-Einstein condensates of Rb85 and Rb87.

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: 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.
