TL;DR: ASTROD-I is a mission concept under study to realize the general concept of ASTROD (Astrodynamical Space Test of Relativity using Optical Devices). This mission concept has one spacecraft carrying a payload of a telescope, five lasers, and a clock together with ground stations (ODSN: Optical Deep Space Network) to test the optical scheme of interferometric and pulse ranging.

TL;DR: In this article, the authors developed a formalism that allows one to calculate the propagation of quantum noise, technical noise, and signals through a linearized quantum optical bus, i.e., a complex composite multibeam optical quantum system, and derived expressions for the output squeezing, the correlation coefficient, and quantum correlation coefficient between output observables and the transfer coefficients.

TL;DR: In this article, a double paddle oscillator was used for the detection of weak forces between masses at sub-mm distance using a rotating aluminium disk with platinum segments, with a force sensitivity of about 10 fN for 1000 s averaging time at room temperature.

TL;DR: The I-SOC (Space Optical Clock on ISS) mission as mentioned in this paper is an ESA mission whose main goal is testing the Einstein equivalence principle and performing relativistic geodesy from space.
