Despite what late-90s Michael Bay movies might tell us, it's pretty unlikely that a huge asteroid will hit Earth in the near future. But ... You never know. This video, created by VICE's Motherboard website, looks at how seriously NASA is taking the potential threat of a major asteroid strike: they've been carrying out simulated asteroid missions at an underwater station for years.
The project is called NASA Extreme Environment Mission Operations (NEEMO), and it's not just concerned with planetary defense - as President Barack Obama says at the beginning of the video, there are plans in place to land astronauts on an asteroid at some point in the future.
Astrophysicist Neil deGrasse Tyson also shows up in the video to talk about a large asteroid that's headed our way (but there's only a 1 in 250,000 chance that it will hit us, and that's not until 2029, so don't worry too much). Check out the vid below:
