Atomic Clock Ensemble in Space (ACES) is an ESA mission that will operate a new generation of atomic clocks in micro-gravity environment of the International Space Station (ISS). Two high performance atomic clocks in ACES: the Space Hydrogen Maser (SHM) and PHARAO, a clock based on laser cooled cesium atoms, are compared on-board the ISS and locked together(More)
The Atomic Clock Ensemble in Space (ACES) is an European Space Agency project to be deployed externally to the Columbus Laboratory on the International Space Station. ACES, consisting of an cold-atom Cesium clock PHARAO and an active space hydrogen maser SHM, will provide frequency stability and accuracy at the 10<sup>&#x2212;16</sup> level which can be(More)
Atomic Clock Ensemble in Space (ACES) is a pioneering mission that will use high performance atomic clocks to test fundamental laws of physics. Operated in the microgravity environment of the International Space Station, the ACES clocks, PHARAO and SHM, will generate a frequency reference reaching instability and inaccuracy at the 1&#x00B7;10<sup>-16</sup>(More)
Having a solid verification and validation Plan and a clear strategy to implement it plays a crucial role in successfully delivering any project e.g. governative, commercial or scientific. A specific tailoring is required but at the same ti me it is fundamental to share needs, experiences and methods spreading the best practices in the Italian Eco-System(More)

ASTRI is a flagship project of the Italian Ministry of Education, University and Research, addressed to the implementation of an end-to-end prototype for the Cherenkov Telescope Array (CTA), an observatory which will be the main representative of the next generation of Imaging Atmospheric Cherenkov Telescopes. It will explore the uppermost end of the Very(More)
