What is rocket science?
Many rockets have multiple ‘shell’s that fall off during escape velocity and is due to the empty fuel containers that are discarded to save on mass, after their fuel has been utilized.
Landing back on earth is trickier than landing on surfaces with no atmosphere or less gravity, and rockets use air resistance, wings and parachutes to slow down the reentry fall.
