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: In this article, the International Space Station is equipped with a glass viewing window and a photographer's lens mounted on a motorized camera pod, and a dedicated small add-on module with single-photon detection, time-tagging and classical communication capabilities.

TL;DR: Silicon Pore Optics (SPO) as discussed by the authors is a new X-ray optics technology under development in Europe, forming the ESA baseline technology for the International Xray Observatory candidate mission studied jointly by ESA, NASA, and JAXA.

TL;DR: In this article, the authors presented a design of a high-sensitivity differential dual species 85Rb/87Rb atom interferometer for space, including physics package, laser system, electronics and software.
