On a day Boeing’s Starliner was the focus on the Space Coast, SpaceX went about the business of building up and shipping out more infrastructure to support its massive Starship rocket.

Some rather large steel pieces that make up the Starship and Super Heavy launch tower that were fabricated at SpaceX’s manufacturing facilities on base at KSC made their way to the turn basin adjacent the press site awaiting a barge headed up the Banana River.

The materials are headed to Texas where SpaceX conducts its test flights of its next-generation rocket. The company announced Saturday that it was pushing its target launch for the fourth orbital flight attempt to June 6, one day later than planned.

It still needs approval from the Federal Aviation Administration, but if it flies, SpaceX will attempt to further progress on the most powerful orbital rocket to ever launch from Earth.

Capable of producing more than 16 million pounds of thrust on liftoff, the 396-foot-tall rocket lifts off from a tower that Elon Musk refers to as Mechazilla. It’s designed to eventually be able to capture back the Super Heavy first stage during return landings through the use of what Musk calls “chopsticks,” which were one of the two massive steel structures being shipped from KSC.

SpaceX has already shipped several pieces for a new Starship tower from KSC to Texas.

In time, it plans to build out updated launch towers at both KSC’s Launch Pad 39-A and Cape Canaveral Space Force Station, depending on the results of two environmental impact studies.

An early version of the KSC Starship tower ceased construction in 2022, and may be redone after SpaceX works out all of the launch pad kinks with test flights from Texas.

The fourth orbital flight attempt looks to build on the success of flight three, although both its upper Starship stage and Super Heavy boosters were not able to make controlled descents during the flight.
