Line 41:
==Test program==
 
SpaceX has publically disclosed a multi-element [[Verification and validation|test program]] that includes both low-altitude (less than {{convert|11500|ft|km|disp=flip}}<ref name=faa201109/>), low-speedvelocity testing of their [[Grasshopper (rocket)|Grasshopper]] technology-demonstrator at their [[Texas]] [[SpaceX Rocket Development and Test Facility|test site]], as well as high-altitude, high-speed ({{convert|300000|ft|km|disp=flip}},<ref name=nbf20130323/>) high-velocity ({{convert|6|Mach|115,000}}<ref name=pm20120207/>) [[ballistic reentry]], [[Deceleration|controlled-deceleration]] and [[Flight control system|controlled]]-[[Atmospheric drag|descent]] tests of post-mission (spent) Falcon 9 booster stages on Falcon 9 [[private spaceflight|commercial]] missions beginning in mid-2013.
