SpaceX Completes Key Water Test at Pad 2 as Preparations for Starship Block 3 Launch Intensify

SpaceX has made significant strides in its launch preparations by successfully completing a full test of the water-cooled top deck on the Orbital Launch Mount (OLM) located at Pad 2. Conducted on Monday, this test is an essential step towards ensuring that the infrastructure can withstand the intense power generated by the 33 Raptor 3 engines during liftoff of the next-generation Super Heavy Booster, which is integral to the Starship program.

The water deluge system is an important upgrade compared to the version used on Pad 1, developed to mitigate the extreme heat and noise generated by the engines, particularly following challenges faced during the inaugural Flight 1. The recent activity at Pad 2 was preceded by visible preparations, including the removal of scaffolding, hinting at the impending main test. The deluge system was activated successfully, and water jetted dramatically from the top deck, showcasing its robust design.

Looking ahead, Pad 2 is set to face its first major test when Booster 19 is rolled out for a static fire later this month. This version, which will support Starship Flight 12, has just completed a series of demanding cryogenic proof tests at a separate facility, successfully addressing concerns that previously hindered the earlier Booster 18 model. Following these preparations, Booster 19 has returned to Mega Bay 1, where the installation of its 33 engines is ongoing.

Pad 2’s readiness is critical, with several tasks still in progress, including improvements to the ship quick disconnect arm and the installation of a protective roof on the launch tower. This protective feature is being added to safeguard equipment during future ship-catch operations and is expected to be completed within the next month.

However, Pad 2 has not yet undergone an important step: flowing cryogenic propellants into a vehicle. This prompts discussions within aerospace circles about the necessity of conducting a full-stack wet dress rehearsal (WDR). Such a rehearsal would involve comprehensive propellant loading with both the booster and ship in place on the pad and could reveal vital insights into how the new Block 3 vehicles interact with the ground systems, potentially preventing issues from arising during testing or flight.

At the same time, SpaceX is also working on revamping Pad 1 to serve as an additional operational launch site. With Pad 2 taking the lead for upcoming launches, crews have been focused on ensuring Pad 1 meets current standards, including a new water-cooled launch mount and advanced systems for handling flames and booster recovery. Groundwork at Pad 1 shows consistent advancement, further aided by safety measures like ‘Continuous Flight Auger’ piling for the flame trench, aimed at managing soil and groundwater challenges similar to those faced by NASA in the past.

Meanwhile, activities at the tank farm signal ongoing preparations for future vehicle operations, including venting operations for oxygen and methane, which are indicative of thorough checks on valves and connections. These efforts are set to ramp up as SpaceX gears up for an increased launch cadence.

As developments progress, the focus remains on completing Booster 19’s preparations and getting Pad 2 operational. The next few weeks are critical as SpaceX moves closer to the historic Flight 12, which will mark the debut of the highly anticipated Starship Block 3.
