A four-tonne piece of a discarded SpaceX Falcon 9 second stage is believed to have unintentionally struck the Moon on Wednesday, crashing at about 5,400 mph at roughly 6.35am BST. The booster section, described as the size of a building, was left in space after a January 2025 launch that sent a Firefly Aerospace lunar lander toward the Moon and had dumped its remaining fuel. NASA predicted the impact would carve a crater about 60 feet wide and 12 feet deep and eject a miles-long plume of lunar dust visible only with telescopes and cameras. Astronomers had only recently determined the stage’s uncontrolled trajectory would end at the Moon, with SpaceX’s Julianna Scheiman saying solar activity and gravity put it on a lunar path. Bill Gray, author of widely used astronomy software, said the collision may offer minor scientific interest and highlights concerns about disposal of leftover space hardware. NASA spokesperson Jimi Russell said the event posed no danger to Earth and that NASA scientists plan to image the site before and after impact to study artificial impacts and crater formation.
