Watch SpaceX test new Starship water-deluge system for 1st time (video)

Now that's a lot of water.

On Friday (July 28), SpaceX conducted the first full-up test of the new deluge system at its Starbase site in South Texas, spraying immense fountains of water up toward and around the facility's orbital launch mount.

The company and its founder and CEO, Elon Musk, posted several videos of the test via social media Friday, showing the system in action from multiple angles.

"New water deluge system to protect against the immense heat & force of Starship launch," Musk said in one video-sharing post.

Starship is SpaceX's next-generation transportation system, which the company is developing to take people and cargo to the moon, Mars and beyond. 

The 394-foot-tall (120 meters) Starship is the biggest and most powerful rocket ever built, and its "immense heat & force" were on full display on April 20. On that day, SpaceX launched a fully stacked Starship for the first time ever, on a test flight that aimed to send its upper stage much of the way around Earth. That didn't happen, however; the vehicle suffered a few problems during launch, and SpaceX sent a self-destruct command, detonating Starship four minutes into flight.

The April 20 launch also did significant damage to Starbase's orbital launch mount, blasting out a sizable crater beneath the structure and raining rocks and other debris down on the surrounding area.

The new deluge system, installed beneath the orbital launch mount, is an attempt to minimize such damage going forward. It consists of a reinforced steel plate that spouts huge amounts of water upward; Musk has compared it to an upside-down shower head.

SpaceX is currently gearing up for the second-ever test launch of Starship, but it's unclear when that liftoff will occur. Even if the vehicle is ready to go soon, regulatory hurdles may still remain; a coalition of environmental and Indigenous groups is currently suing the U.S. Federal Aviation Administration, saying the agency — which grants launch licenses — didn't properly assess the damage that a Starship launch could cause to the South Texas ecosystem and community.

    The water will take the heat. How much steam and vapor will it produce? With those long release times, will we be able to see a launch? Or only when it pops out from the cloud?

    Can't believe the merits of the alleged lawsuit will hold up the next evolution of manned spaceflight. Cut them a check and send them away. Reminds me of the telescope in Hawaii. Ignorance is bliss of the unknown...

    suspect vaporization will shine thru with enough heat to displace the thermodynamics of water turning to all steam. either way will be a spectacular display of water and fire fighting each other

    Yes, this will make a huge cloud of steam! It will cool everything down and hide the first ten seconds or so.

    Appears one check mark completed for the next launch of the Starship. I have to ask is all that water caught and treatment before it is released back into the near shore brackish wetlands and ocean or is it just allowed to runoff carrying the load of BOD5 and oil and grease into the ocean. Hope the FAA and NASA approve another launch shortly. It is very impressive that large amount of cooling water that will hopefully carry away the heat and protect the concrete of the launch pad, any calc on the latent heat of evaporation and .

    We'll have to watch the liftoff in IR. Very high dynamic range IR. A cool rocket and a hot engine. Do we have such? For a detailed high res image of those temps?

    From the Final Environmental Assessment June 2022, page 111

    "SpaceX would manage surface water discharges from runoff during construction and operations according to the requirements of the TPDES."

    From what I have read, it is not clear that this water will be captured along with the usual rain water runoff.

    And, are we sure it needs to be? The rocket exhaust should be mostly CO2 and water. Not sure what else the steam-cleaning of the launch area might produce. Temperature of the runoff might be an issue. Maybe Musk will need to build a big dike around the launch pad?

    Musk agreed in June 2022, when the final Environmental Review was issued, to abide by the Texas Pollutant Disharge Elimination System. But, according to WSJ, he never got the permit.
