SPACEX SUPER HEAVY BOOSTER 3 ROLLED TO STARBASE LAUNCH PAD
SpaceX’s Super Heavy Booster No. 3 stacked at the company’s high bay facility made an appearance last week. The vehicle was transported down Boca Chica’s Highway 4 on July 1, 2021, to a modified section of Pad A, where it is expected to begin cryo testing.
Known as Booster No. 3, or BN3, this engine-less pathfinder vehicle is set to undergo a series of pressure tests in the upcoming weeks at the company’s South Texas launch facility, named Starbase by the company, to evaluate the integrity of the tank itself.
While BN3 is busy pathfinding, common dome sections of BN4, a flight-capable booster, are currently being put together in the High Bay.
The company had originally hoped to make an orbital flight with both Starship and a Super Heavy booster in July. However, according to a tweet from Elon, it seems SpaceX will be happy if both Starship and Super Heavy are stacked by the end of the month, which seems to be a much more realistic expectation.
The company plans on mating Starship 20 (SN20) and BN4 at some point later in the month. These two vehicles are expected to make up the first orbital flight test of the Starship …..
