On a collision course to rock your world
Do you know what happened on 30th June 1908? If not, the United Nation’s hopes to change that with the celebration of World Asteroid Day on 30th June- 2021 marking the 5th year of celebration. In 1908, on 30th June, Earth experienced the largest asteroid impact in recorded history: the Siberia Tunguska event. The explosion occurred over Siberia and flattened an estimated 80 million trees, that’s over 830 square miles of forest. Tunguska is the largest cosmic impact witnessed by modern humans and is characteristic of the sort of impact we are likely to have to protect against in the future. Tunguska led astronomers to research more into possible asteroid collisions ensuring they are best equipped to protect the world from future impacts. This year, World Asteroid Day will celebrate the 2021 launch of three new asteroid missions, NASA’s Lucy, NEA Scout and DART – the world’s first mission to test an asteroid deflection technique.
On the day itself, discussions with be led by key speakers, ranging from World Asteroid Day co-founder and renowned guitarist, Brian May, comedian Bill Nye, NASA scientists and engineers and astronauts who can give insider information about what it is like to see asteroids up close.
