Grasshopper is a suborbital technological research vehicle built by SpaceX to develop a reusable, vertical landing first stage for the Falcon-9 rocket.
Grasshopper consists of the first stage of Falcon-9 v1.0, fitted with only one Merlin-1D engine and fixed landing legs. SpaceX conducts low altitude flights of Grasshopper at the company’s McGregor, Texas, test site.
Falcon-9R-Dev is test vehicle for the Falcon-9 v1.1 and consists of the longer first stage of Falcon-9 v1.1(ex), fitted with three Merlin-1D engine and operational deployable lightweight landing legs. SpaceX conducts low altitude flights of the Falcon-9R-Dev at the company’s McGregor, Texas, test site and plans to conduct higher altitude suborbital tests with a second vehicle at Spaceport America, a new commercial spaceport in New Mexico. The second vehicle was apparently converted to the Abort Test Booster to be used in the Crew Dragon Flight Abort Test at Vandenberg.
