ESA is Building an Early Warning System for Dangerous Asteroids By Nancy_A
Lagrange points are locations in space where the gravitational pull from the Earth equals the pull from the Sun, and satellites can reside with less ‘orbital maintenance’ than those orbiting Earth or flying out to deep space.ESA says that NEOMIR will monitor a close ring around the Sun, a region that is impossible to observe from telescopes on Earth because of the Sun’s blinding glare.
Asteroids in that region that are 20 meters and larger and heading toward Earth should be detected by NEOMIR at least three weeks in advance. In the worst-case scenario, in which the asteroid is spotted passing near the spacecraft, we would get a minimum of three days’ warning – the fastest the asteroid could move from L1 to Earth.
is set to launch in 2026 and it should fulfil the US Congress mandate to discover 90% of near-Earth objects larger than 140-meters in diameter.An asteroid similar to the Chelyabinsk meteor – which caused an airburst event as it broke up in Earth’s atmosphere above the city of Chelyabinsk in Russia – is the type of space rock NEOMIR could detect. That meteor’s radiant, or source direction, was close to the Sun and it came in undetected by other observatories.
