SpaceX readying Starhopper for hops in Texas as Pad 39A plans materialize in Florida
SpaceX readying Starhopper for hops in Texas as Pad 39A plans materialize in Florida
For instance, up until recently, the company was planning to utilize Raptor SN4 for the untethered hops. However, the company has now decided to utilize this engine only for fit checks, and will instead perform the hops with SN5 – the latest Raptor to come out of SpaceX’s factory in Hawthorne, California.
It is understood that the Texas-based vehicle has been designated Mk.1 while the Florida-based vehicle has been designated Mk.2.
SpaceX already has two launch pads in Florida, but both are being actively used to support the Falcon 9 and Falcon Heavy rockets. Therefore, the company had been looking at a variety of options for launching Starship.
However, Pad 39A has recently become the frontrunner to support Starship. While it is perhaps the obvious choice when considering its large size, the launch complex is also needed to support critically important Falcon launches.
