Spacex has proven that their rockets can be reused after each flight. This bodes well for the fledgling company.
Last week the Falcon 9 sent satellites into orbit and then reentered Earth’s atmosphere and soft landed in the Atlantic Ocean.
More test are to happen but the Falcon Heavy will be the vehicle that will be the full reusable platform.
“We will attempt our next water landing on flight 13 of Falcon 9, but with a low probability of success. Flights 14 and 15 will attempt to land on a solid surface with an improved probability of success.”[SOURCE](http://www.spacex.com/news/2014/07/22/spacex-soft-lands-falcon-9-rocket-first-stage)
