The Earth is silently but continuously threatened by near-earth objects—asteroids—some of which we will not spot until it is too late.The National Space Society works tirelessly to urge Congress to address these potential Earth-wrecking objects, but much remains to be done. Congratulations to NASA and the DART mission team for your achievement in this area. You can make a donation to help protect our planet at go.nss.org/defendearth.
