NASA's Plan to Protect Earth from Asteroid Collisions
TLDR Scientists are developing technology to track and predict the path of asteroids, with the goal of preventing them from hitting Earth. NASA is planning to launch a spacecraft called DART to push a medium-sized asteroid out of the way, using a nuclear bomb to heat up its surface and create pressure that will change its course.
Timestamped Summary
00:00
An asteroid exploded over Russia, causing damage and injuries, while an asteroid researcher in Vienna realized it was a different asteroid than the one he was tracking.
03:56
Scientists were tracking one asteroid, Duende, but missed another one, Chelyabinsk, that ended up hitting Earth, and the reason for this discrepancy is explained by Kathy Plesko from the Los Alamos National Laboratory.
08:22
Scientists were able to track and predict the path of the asteroid Duende because it was brighter and easier to spot than most asteroids, unlike the smaller asteroid Kelly Arbitsk which was missed.
12:07
Asteroids come in different sizes, and the larger they are, the more dangerous they become, with asteroids around one kilometer in size posing a significant threat to Earth and having the potential to cause widespread destruction and loss of life.
17:22
NASA is planning to launch a spacecraft called DART to push a medium-sized asteroid out of the way by hitting it, with the mission being the first of its kind and involving significant technological challenges.
21:18
NASA plans to use a nuclear bomb to push a medium-sized asteroid out of the way by heating up its surface and creating pressure that will push the asteroid away.
25:34
Nudging an asteroid off its course could change its speed and prevent it from hitting Earth, but it would require plenty of time and a small change in velocity.
29:46
We have the technology to potentially push an asteroid off course and prevent it from hitting the Earth, so the chances of a big asteroid hitting us in our lifetime are very small.
