Shockingly, an asteroid hit Earth last week. The news in itself is not that shocking as many pebble-sized asteroids get pulled by Earth’s gravity and burn up in the atmosphere. What was truly surprising is that NASA was able to detect the asteroid just two hours before it crashed onto Earth. Worryingly, this would not have given NASA any time to react or stop the asteroid. However, on the brighter side, the entire incident weaves a remarkable tale of detection skills and luck of an astronomer and the technological prowess of an important tool in NASA’s planetary defense system called Scout. And if scientists are to be believed, it shows unprecedented progress in Earth’s preparedness against a potentially catastrophic asteroid strike. Yes, unprecedented.
Krisztian Sarneczky was looking at the stars on March 11 at the Konkoly Observatory near Budapest. Gazing through the night sky, he was scanning for any unidentified objects. And all of a sudden he came across a dimly lit object moving at an intriguingly fast pace. Within half an hour, he was certain that the asteroid was headed towards the Earth. But instead of being afraid, he was ecstatic. It was primarily because the size of the asteroid, about six feet, made it harmless. But also, because he had just discovered a new near Earth object (NEO). “I have dreamed of such a discovery many times, but it seemed impossible,” he told the New York Times.
Within the next hour of detecting the asteroid which was later named 2022 EB5, he shared his findings and data with NASA. This is where the Scout system comes into play.
Scout is a software that uses the data and observations of astronomers when they report near-Earth objects and figures out approximately where and when their
