A SpaceX rocket piece floating in space since last ‌year was expected to have smashed into the moon at high speed early Wednesday morning, though the impact was unlikely to be confirmed for at least several hours, Reuters reports. The school-bus-size object is the second stage of a SpaceX Falcon 9 rocket that had launched a lunar lander from Firefly Aerospace toward the moon in January 2025. Weighing 4 metric tons (4,000 kg), the rocket body had been due to ​hit the moon around 2:35 a.m. The impact was unintentional, SpaceX said. The rocket piece was expected to hit ​Einstein Crater on the moon’s western limb, which is often difficult to see from Earth.
