This is a reusable Falcon 9 not the Grasshopper. The Grasshopper program ended last year and used a smaller rocket (AFAIK).

Wikipedia lists the F9R also as "Grasshopper v1.1" -- cf. http://en.wikipedia.org/wiki/Grasshopper_(rocket)#Grasshoppe...

Ah, did not see that. It's confusing since the Falcon 9 Wikipedia page also has the Falcon 9 Reusable: https://en.wikipedia.org/wiki/Falcon_9#Falcon_9-R
