Flight Algorithms for Disaggregated Space Architectures (FADER) is an ERC-funded research aimed at contributing to the engineering and scientific knowledge of disaggregated spacecraft architectures. Particularly, it is focused on the relative dynamics of the modules of these systems. The long-term relative dynamics of fractionated architectures are different from those of traditional formation flying satellites.

Space Autonomous Mission for Swarming and Geo-locating Nanosatellites (SAMSON) is a new satellite mission, led by the Asher Space Research Institute at Technion and supported by the Adelis Foundation. Adelis-SAMSON will include three nano-satellites, built based on the the CubeSat standard, and designed in collaboration with Israeli industries (IAI, RAFAEL, Elta).

In this project, various optical systems adjust on their own to approach the best image possible. In one realization, a  telescope made of four non-contiguous segment mirrors, mimics a space telescope. Without a wave front sensor, the system optimizes itself by simulated annealing in hardware. In other active optics realizations, simpler telescopes are being adjusted by the same optimization scheme. Various approaches to stochastic optimizations are compared to more directional searches

In this project the Hanbury-Brown and Twiss experiment is tested with the purpose of performing it in space. Compared to amplitude interferometry requiring 30 nanometer precision, the mechanical requirements here are not exacting, on the 3mm scale. A number of separate light collectors register single photons arriving from the same celestial object. The correlation of these photon streams, at a central station, allows measurement of the size of distant stars and galaxies.
