"One of the factors that make space travel so expensive is the fact that most of the equipment used to put cargo or people in orbit is destroyed after each use. SpaceX CEO Elon Musk has famously likened this to throwing away a brand new 747 after a single flight to London.
From the beginning, his company has sought to make spaceflight possible with reusable components. Initially, SpaceX tried to use parachutes to slow down rocket stages as they descended, but they broke apart due to stress and heat, so the company switched to the current powered landing approach in 2011."

BTW. I finished my federal and state income tax work yestiddy and am feeling liberated. pl
