Actualité spatiale algérienne

Il ne s'agit pas d'un projet de l'agence spatiale algérienne mais l'Algérie participe au projet de japonais de l'installation d'un module sur ISS afin de détecter les particules hautement énergétique provenant de l'espace grâce à l'observation l'atmosphère terrestre

JEM-EUSO on the International Space Station is a new type of observatory, based on a UV telescope, which uses the whole Earth as detector. It will observe, from an altitude of ∼ 400 km, the fluorescence tracks produced at (330-400) nm  by  Extensive Air Showers (EAS)  originated by UHE primaries which traverse the Earth’s atmosphere at ultra-relativistic speed.
The launch is foreseen for the 2018 and the mission will last at least 5 years. JEM-EUSO will be operated for three years in Nadir configuration to maximize statistics at the lowest energies in order to cross calibrate with the current generation of ground-based detectors. The instrument will be then tilted (about 30°) with respect to Nadir in order to exploit a larger amount of atmosphere and to maximize the statistics of events at the highest energies. JEM-EUSO will significantly increase the exposure to  UHECRs compared to the largest ground-based air shower arrays presently in operation.
Two test experiments are currently prepared; one to observe the fluorescence background from the edge of the Atmosphere (EUSO-Balloon) and the other for an inter-calibration with the fluorescence detector (EUSO-TA).
