Starship Flight 4 begins Wet Dress Rehearsal campaign
SpaceX is gearing up for Flight 4. The start of full stack testing on Thursday resulted in a partial load of propellants, which will be followed by a full Wet Dress Rerhasal in the coming days. In tandem with preparation for the next flight, SpaceX is making progress on its future ambitions with a second tower being prepared at Starbase, while information has come to light on SpaceX’s 39A Starship pad in Florida.
SpaceX rolled out both vehicles for Flight 4 of Starship and stacked them on the Orbital Launch Mount (OLM) ahead of full-stack testing. So far, both Booster 11 and Ship 29 have completed their individual test campaigns and have completed a partial load tanking test on May 16, with a possibility of a Wet Dress Rehearsal (WDR) as early as Saturday, May 18.
A WDR is when the vehicle is fully loaded with propellant and put through a simulated launch countdown for testing purposes. For Starship, this means loading all tanks to flight levels with Liquid Methane (LCH4) and Liquid Oxygen (LOX).
