Hypothetical Asteroid Devastates Europe in Doomsday NASA Simulation AYLIN WOODWARD & MORGAN MCFALL-JOHNSEN, BUSINESS INSIDER 3 MAY 2021 Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth. A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.
With each passing day of the exercise, the participants learned more about the asteroid's size, trajectory, and chance of impact. Then they had to cooperate and use their technological knowledge to see if anything could be done to stop the space rock.
