How China plans to challenge SpaceX with reusable rockets
State contractor says its first reusable rocket could come in two years
From Elon Musk’s SpaceX to Jeff Bezos’ Blue Origin, US companies are pumping billions of dollars into developing reusable rockets that can safely return to Earth -- and then take off again later.
For decades, sending rockets into space was extremely expensive. Launch vehicles cost hundreds of millions of dollars to build -- but they can only fly once, burning up during their return to Earth. The ability to reuse rocket components is essential to driving down costs.
