A 3-tonne rocket part will be smashing into the moon of Friday, leaving a huge crater on its far side. The leftover rocket chunk will be crashing into the moon at 9,300 km/h away from any telescopes’ line of sight. Unfortunately, it will take weeks, or months to actually confirm the impact through satellite images. This is because the moon is always showing the same side to Earth.
Some experts believe the debris has been tumbling through space since China launched it nearly a decade ago. However, Chinese officials are dubious it’s theirs. Scientists predict the object will carve out a hole 10 to 20 metres across. It will also send moon dust flying hundreds of kilometres across.
Most low-orbiting space junk is easy for space agencies to track. Objects. launched deeper into space are more unlikely to hit anything and are usually soon forgotten. There are a handful of observers that will actually continue to track these objects because they enjoy playing celestial detective.
