NASA to launch telescope that will detect asteroids approaching Earth

Seeing Far Seeing Transparent: The Space Telescope will detect 90% of asteroids larger than 140 meters in its first decade of operation

NASA has approved the development of a new space telescope that will give humanity early warning of asteroids and comets that could collide with the Earth . Of 50 million miles from our home world. 

The planet is still vulnerable

It is estimated that NASA has so far detected only about 40% of near-Earth asteroids larger than 140 meters in diameter, out of an estimated population of 25,000 such objects. Regional, continental and even global.

In 2005, the US Congress instructed NASA to discover, characterize, catalog and track 90% of the major asteroids by 2020. This goal was not achieved for two main reasons: First, some asteroids come from the dazzling sun, which does not allow us to detect dim objects like Asteroids are a problem that currently has no satisfactory technological solution – and the fear is of a large object that will suddenly emerge from the direction of the sun.

Another problem is the difficulty of terrestrial telescopes to scan the sky continuously. Telescopes on the ground suffer from two limitations: they work only at night – and only on clear nights. So in 2013 NASA revived a space telescope in the infrared called Wide-field Infrared Survey Explorer, or WISE, and converted it to close-knit object hunting – a mission that became NEOWISE. Newways was a great success, and the telescope found about 2,000 asteroids New, but NASA understands that they will need a much more powerful and powerful space telescope to meet the target set for them by Congress.
