paragraph_text: Reusability
  
  SpaceX planned from the beginning to make both stages reusable. The first stages of early Falcon flights were equipped with parachutes and were covered with a layer of ablative cork to allow them to survive atmospheric re-entry. These were defeated by the accompanying aerodynamic stress and heating. The stages were salt-water corrosion-resistant.
  
  In late 2011, SpaceX eliminated parachutes in favor of powered descent. The design was complete by February 2012.
  
  Powered landings were first flight-tested with the suborbital Grasshopper rocket. Between 2012 and 2013, this low-altitude, low-speed demonstration test vehicle made eight vertical landings, including a 79-second round-trip flight to an altitude of 744 m (2,441 ft). In March 2013, SpaceX announced that as of the first v1.1 flight, every booster would be equipped for powered descent.
