SpaceX moon crash reveals space junk hazard, Australia faces elevated risk

A SpaceX rocket stage crashed into the moon this week, highlighting the growing threat space junk poses to Earth, with Australia at elevated risk. The four-tonne stage, travelling 2.43 km/s, left an estimated 18-metre-wide crater. Astronomers lack immediate imagery; astrophysicist Brad Tucker noted about a tonne of debris hits Earth daily, calling the crash symptomatic of a growing problem. The crash may yield scientific benefits, exposing lunar material for study. Australia, along with parts of Africa and South America, faces higher debris risk due to its latitude, though overall risk remains low.
