NASA's DART spacecraft is closing in on its appointment with Dimorphos, but the energetic encounter is just the very speartip of global efforts to keep life on Earth safe from asteroid impacts.

NASA's DART mission, which will slam into an asteroid on Sept. 26, is not just a planetary defense exercise; it's also an opportunity to learn how binary asteroids form.

In 1961, the US astrophysicist Frank Drake, who passed away on Sept. 2 at the age of 92, came up with an equation to estimate the number of intelligent civilizations in the Milky Way right now.

When NASA's DART mission slams itself into an asteroid called Dimorphos, three different science spacecraft will be trying to watch the action.

NASA's DART mission mimics what scientists would do if an asteroid were headed toward Earth, but there are a few differences compared to defense against a real asteroid impact.
