NASA formally announces that asteroid 2024 YR4 now poses "no significant threat" to Earth in 2032 and beyond as the chances of an impact drop to 1-in-59,000 (0.0017%). This means a planetary defense mission to intercept and deflect the object in 2028 during a close flyby of Earth is no longer necessary. 2025-02-24
NASA's Center for Near-Earth Object Studies says that the probability of asteroid 2024 YR impacting Earth on 22 December 2032 has increased to 2.3%, or a (1-in-43) chance, following further observations of its trajectory. More observations are planned in the coming months to gather data on the asteroid before it moves too far away from Earth-based telescopes to be accurately observed. 2025-02-6
The European Space Agency spacecraft "Hera" is successfully launched on a Falcon 9 Block 5 rocket by SpaceX from the Cape Canaveral Space Force Station in Florida, United States. The spacecraft will study the asteroid 65803 Didymos and evaluate the impact of the earlier Double Asteroid Redirection Test. 2024-10-7
