NASA has a new spacecraft that can save Earth. Unfortunately, it isn’t funded and it won’t make its first test flight until 2022 at the earliest.
If a “nation killer” asteroid comes heading our way, Bruce Willis won’t be able to save us.
If an asteroid the size of an 18-wheeler collided with Earth it would cause massive destruction. And since there are a lot of these, can we at least keep an eye on where they are? Not very well.
Are asteroids humanity’s Armageddon or the promised land? It depends on which gets here first.
