- FlyEye (Œil de mouche) ou NEOSTEL (acronyme de Near Earth Object Survey TELescope) est un réseau de télescopes terrestres développé sous l'égide de l'Agence spatiale européenne qui a pour mission d'effectuer un relevé astronomique systématique des astéroïdes géocroiseurs. Pour remplir leur objectif ces télescopes disposent d'une optique dont l'architecture permet d'observer un large champ de vue (44 degrés carrés). Deux prototypes destinés à valider le traitement des données sont opérationnels à La Silla (Chili) et en Espagne. La construction du premier télescope opérationnel Flyeye-1 a débuté en Sicile. FleEye est un des principaux projets du programme de défense planétaire de l'Agence spatiale européenne. Celle-ci envisage de disposer à terme de quatre à cinq télescopes répartis dans les deux hémisphères à des longitudes différentes. (fr)
- The Near Earth Object Survey TELescope (NEOSTEL - also known as "Flyeye") is an astronomical survey and early-warning system for detecting near-Earth objects sized 40 metres (130 feet) and above a few weeks before they impact Earth. NEOSTEL is a project founded by the European Space Agency (ESA), starting with an initial prototype currently under construction at OHB in Milan, Italy. The telescope is of a new "fly-eye" design inspired by the wide field of vision from a fly's eye. The design combines a single objective reflector with multiple sets of optics and CCDs, giving a very wide field of view (around 45 deg2, or 220 times the area of the full moon). When complete it will have one of the widest fields of view of any telescope and be able to survey the majority of the visible sky in a single night. If the initial prototype is successful, three more telescopes are planned, in complementary positions around the globe close to the equator. In terms of light gathering power, the size of the primary mirror is not directly comparable to more conventional telescopes because of the novel design, but is equivalent to a conventional 1-metre telescope and should have a limiting magnitude of around 21. The project is part of the NEO Segment of ESA's Space Situational Awareness Programme. The telescope itself should be complete by end of 2019, and installation on Mount Mufara, Sicily should be complete in 2020, having been agreed with the Italian Space Agency in October 2018. Development of the telescope was reported as on track in Feb 2019. (en)
- Il Near Earth Object Survey TELescope (in italiano "Telescopio di Sorveglianza degli Oggetti Vicino alla Terra") abbreviato in NEOSTEL e conosciuto anche come "Flyeye", è un sistema di rilevamento e monitoraggio astronomico di oggetti near-Earth di dimensioni pari o superiori ai 40 m, in grado di dare un preallarme alcune settimane prima del eventuale impatto con la terra, ottenuto per mezzo di innovativi telescopi ottici NEOSTEL è un progetto finanziato dall'Agenzia Spaziale Europea, presentato con un prototipo presso la OHB di Turate vicino a Como. Il telescopio appartiene alla nuova tipologia di ottiche "fly-eye" ispirate all'ampio campo visivo dell'occhio composto degli insetti. In termini di capacità di concentrazione della luce, la dimensione dello specchio primario non è direttamente comparabile con quella di telescopi ottici più convenzionali a causa del design innovativo, ma è equivalente a quella di un telescopio convenzionale con specchio primario di 1 m e dovrebbe avere un magnitudine limite di circa 21.
