The Starship Program had its greatest yr to this point in 2023, with two full stack flights, huge modifications to the launch pad and surrounding techniques, extending testing at Masseys, and large modifications to the manufacturing website.
Shipyard
At the beginning of 2023, the Manufacturing Website nonetheless included the Windbreak, Midbay, and Tent 1 and a couple of. Moreover, the manufacturing website nonetheless hadn’t been totally related to the first energy grid. All through 2023, many modifications occurred that can assist SpaceX optimize Starship manufacturing and upkeep going ahead.
This yr SpaceX started constructing the second Mega Bay (Ship Bay) to extend its functionality for stacking automobiles. By now, it’s practically sure that this new bay will exchange Excessive Bay when it comes to ship building. The format will appear to be what Mega Bay 1 (Booster Bay) now appears to be like like.
Each Mega Bays will function one turntable within the entrance nook, which might be used to stack automobiles by rotating the stack alongside a robotic welder contained in the bay. Then, on the again facet of the bays, there are three work platforms that can permit SpaceX to put in engines extra simply and do separate work on boosters and ships. Ship 29 is the primary ship to make use of the brand new Ship Bay for engine set up and inside work.

SpaceX additionally upgraded the bridge cranes inside Mega Bay 1 so they may carry a booster with out engines with just one crane as a substitute of two, which they used to should do. Nonetheless, as soon as totally fitted with engines and shielding, lifting a booster requires each cranes.
With Starfactory, SpaceX made nice progress with the Windbreak, Midbay, and Tent 1 and a couple of demolition. By the point crews are fully completed working within the space, the manufacturing unit might be round 800,000 sq. ft since Tent 3 nonetheless must be demolished.
At present, solely a number of the format of Starfactory is understood, such because the again northeast nook having a press pit, which is for a hydraulic press to stamp and crate elements. The upper part closest to Freeway 4 might be used for nosecone building. In truth, there may be already a nosecone welding jig contained in the manufacturing unit.
As soon as Starfactory kicks into full gear together with each the Booster Bay and Ship Bay, SpaceX’s manufacturing of ships and boosters will considerably improve. This may permit for extra testing and flights so SpaceX can fulfill its greatest contract for Starship, which is the Human Touchdown System for NASA’s Artemis Moon program.

Sanchez Website
Over this previous yr, the Sanchez website has undergone many modifications. At the beginning of the yr, Sanchez nonetheless had the propellant manufacturing plant and was lacking many issues now situated there. In the course of the course of the yr, SpaceX used Sanchez to prefabricate the sections of the brand new Excessive Bay after which transfer them to the brand new bay for the LR-11000 crane to be positioned into place.
For the reason that Starfactory growth required the removing of the Floor Assist Gear (GSE) constructing, SpaceX relocated it to the western nook of Sanchez and upgraded it with insulation within the course of. With insulation and air-con, higher work and welding environments have been created within the constructing. Alongside the GSE constructing, building began on two new white rings and two new black rings.

These white rings have been the work stands for each the Booster Bay (Mega Bay 1) and the brand new Ship Bay (New Excessive Bay). The black rings have been a brand new transport stand for boosters that are automated in comparison with the outdated transport stands.
One other important addition to Sanchez this yr was the ship engine set up stand close to the Rocket Backyard which enormously simplified the set up of engines on ships. Nonetheless, this stand could also be scrapped because the Ship Bay will take over its features.
SpaceX is now making ready Sanchez to obtain all the accomplished tower sections at Roberts Street. These might be for the second Launch Pad at Starbase, and as of proper now, it’s unclear when building will begin.
Lastly, the Propellant Manufacturing Plant at Sanchez has been dismantled. It’s unknown if SpaceX is giving up and producing its propellant or if it intends to do it at one other location.
Masseys
This yr, SpaceX carried out the primary ship cryo-proof take a look at with Ship 25 and later began doing boosters, beginning with Booster 10. SpaceX has constructed two cellular thrust ram stands, one for ship and one for booster. These can transport a ship or booster from the Shipyard to Masseys, carry out the mandatory cryo and structural load checks, after which transport them again.
Lately, tons of groundwork has occurred at Masseys, and SpaceX has even added subcoolers. As of now, it’s unknown precisely what might be constructed there. At present, Booster 12 is at Masseys for cryo testing, with this booster probably slated for Flight 5.

Launch Website
The Launch Website has modified considerably over the course of 2023, particularly with two orbital take a look at flights having been launched from Orbital Pad A at Starbase. Simply earlier than the primary flight, SpaceX accomplished the set up of the ultimate items of protecting on the Orbital Launch Mount (OLM). This was one of many remaining items of OLM building wanted earlier than the primary flight.
After the primary flight, there was important injury to the bottom of the pad, which required a whole redesign of the pad’s basis and the set up of a brand new water-cooled metal plate flame deflector.
This beefed up the inspiration to be round 4.5 meters of concrete and metal and pilings happening not less than 20 meters, in comparison with the measly 1 meter or so of simply fondag concrete used for Flight 1. The opposite huge addition was the brand new water flame deflector, which is a metal plate with many small holes used to spray water towards the exhaust plume of the booster with the intention to shield the bottom and scale back shock to floor tools.

This technique proved its price throughout Flight 2 when the injury to the pad was minimal. The turnaround between Flight 1 and Booster 9 being mounted to the OLM was three months in comparison with Flight 2 and Booster 10, which was only one month.
SpaceX has additionally upgraded the Orbital Tank Farm with spots for 9 extra horizontal tanks. The corporate additionally lastly added two new pumps and 4 subcoolers on the liquid oxygen facet and one pump and one subcooler on the methane facet. There have been spots for this growth ever since they initially constructed the tank farm. As soon as all are totally connected and built-in, SpaceX will be capable of tank and de-tank ships and boosters a lot quicker.
Close to the top of the yr, Suborbital Pad A was demolished. SpaceX hasn’t used this pad for some time, and it’s unclear what SpaceX will use the area for sooner or later.

Flights and testing
SpaceX had a really eventful yr with testing at Starbase, with two full-stack flight checks and plenty of testing milestones. First, SpaceX carried out the primary full-stack Moist Gown Rehearsal with Booster 7 and Ship 24. This stack would later fly the primary flight. The expectations for the flight weren’t excessive, and the stack was misplaced 4 minutes into the flight.
The flight had many points, however the primary challenge was a hearth that had damaged out in Booster 7’s engine bay and burned by way of a number of wire harnesses, which reduce off the flight pc’s management of the engines. Each automobiles additionally had points with their Flight Termination Programs (FTS).

After this flight, SpaceX upgraded the hearth suppression system for Boosters to keep away from further engine bay fires and upgraded the FTS on future Boosters and Ships. With the addition of Sizzling Staging and different upgrades, Flight 2 carried out much better. Booster 9 made all of it the way in which to predominant engine cutoff with out shedding a single engine, after which Ship 25, utilizing hostaging, separated from the booster completely.
Nonetheless, shortly after stage separation, Booster 9 was terminated as a consequence of potential points with gasoline sloshing. Ship 25 practically made all of it the way in which to the second stage engine cutoff; nonetheless, an unknown challenge brought on the FTS to be activated, and thus the automobile was destroyed.

Together with the 2 flight checks, SpaceX achieved a full 33-engine static fireplace on Booster 9 and has continued to attain flawless six-engine static fires on ships. Ship 26 and Ship 28 just lately carried out single-engine static fires with flight-like situations to simulate a de-orbit burn.
To finish the yr, SpaceX has Ship 28 and Booster 10 out on the pad, with Ship 28 already performing a spin prime and two static fires. Booster 10 additionally tried after which accomplished a static fireplace. General, it has been a really profitable yr for the Starship program, with many extra milestones forward.
KSC and the longer term
SpaceX has not labored on the Starship pad at LC-39A for a number of months. The plans for a Florida Starship pad haven’t been canceled, however SpaceX is extra targeted on flying from Starbase as they determine the entire system. It’s price noting that SpaceX has huge plans to develop its Starship capabilities with further amenities much like SpaceX’s facility at Roberts Street, however it’s unknown when building will begin.
