Scientists said on March 6, 2026 that a NASA spacecraft hit a small asteroid in space. The goal was to change its path and learn how to protect Earth. The test happened in 2022 when the spacecraft hit an asteroid called Dimorphos. This asteroid moves around a bigger one named Didymos. The small hit helped change its movement a little. Scientists said even a small change can help in the future. After the crash, scientists began to study the results. They used tools and data from many places. Pieces of rock flew away after the hit, making the effect stronger. The test was safe because the asteroid was not dangerous to Earth. In the future, scientists will send another spacecraft to look at the asteroid again and learn more.
