Defend Earth Today!

As a supporter of The Planetary Society, YOU help sustain Planetary Defense as one of our core enterprises. To decrease the risk of Earth being hit by an asteroid or comet, together we:

  • Help observers find, track, and characterize near-Earth asteroids
  • Support the development of asteroid mitigation technology
  • Collaborate with the space community and decision-makers to develop international response strategies to defend Earth

An asteroid impact is one of the only large-scale natural disasters we can prevent, so we must keep advancing research and technology to make prevention possible. That’s why I’m asking for your help as a planetary defender.

When you make a gift today, your contribution will be matched up to $25,000 thanks to a generous member who also cares about planetary defense!

Asteroid strikes are rare but potentially catastrophic. The earlier we identify any threats, the more likely we are to prevent them. When a dangerous asteroid comes, let’s make sure we’re ready.

Thanks for being a Planetary Defender,

Bruce Betts

Dr. Bruce Betts, Chief Scientist
