The impact is expected near Einstein Crater on the Moon’s sunlit western limb (AP)A drifting SpaceX rocket is on a collision course with the Moon after launching a pair of lunar landers more than a year ago. It will be the second dead rocket known to crash into the Moon accidentally. Mr Fernando anticipates an impact crater nearly 90 feet across and 16 feet deep, too small to see from Earth but visible to spacecraft. Danuri will stray within a mile or two of the SpaceX rocket just two minutes before impact, according to Mr Fernando and his team. Nasa hurled rocket sections and lunar modules into the Moon during the Apollo era for seismic measurements.
