Bug-eyed asteroid hunter: ESA's Flyeye telescope

tech.hindustantimes.com:

Each day we hear about gigantic asteroids or other near-earth objects rushing towards the Earth. Detecting celestial objects which can be hazardous to Earth can be tough due to the vastness of space. To solve this problem and prepare for the early spotting of asteroids, European Space Agency will be developing the automated Flyeye telescope.

This will be the first time in history that an instrument will scan the sky thoroughly and will automatically detect dangerous near-earth objects.

ESA reports the telescope will automatically detect the celestial object and then it will be examined by scientists to be sure they are real detections. Once the data is collected, it will then be sent to the Minor Planet Center for further observation for a better understanding of the near-Earth object's orbit and the likelihood of an impact.

Note that the Flyeye telescope can only detect celestial objects to about 40 m in diameter, making it 3 weeks before the actual impact.

Just like the compound eye of a fly, the new European telescope will divide each image into 16 smaller sub-images, significantly expanding the field of view for improved observation capabilities. As per ESA, these fly-eyed survey telescopes have the performance of a 1 m-diameter telescope with a field of view that spans 6.7° x 6.7°, or around 45 square degrees.

“The extremely wide field of the new telescopes will allow us to cover a large area of the sky in just one night. This will reduce the chance that we miss any interesting object," says Detlef Koschny, senior asteroid expert at ESA.

The first Flyeye Telescope will be placed at the top of the 1865-metre Monte Mufara mountain in Sicily, Italy. The Italian Space Agency (ASI) will be developing the complete
