The Starship Orbital Launch Pad project at Starbase, Texas, continues to evolve from a test facility into one of the world’s most ambitious commercial spaceport developments. Located at Boca Chica in Cameron County, the complex serves as the primary launch, manufacturing, testing and recovery hub for SpaceX’s fully reusable Starship-Super Heavy launch system.
Recent regulatory approvals have enabled SpaceX to increase annual launch operations from five to as many as 25 orbital missions. This is while expanding launch infrastructure, including a second launch pad, additional integration towers, landing facilities and propellant systems. The expansion also features liquefaction infrastructure and the Starpipe natural gas pipeline designed to directly supply fuel to rockets at the Starbase facility.
The orbital launch complex is also central to SpaceX’s plans for Starlink deployment, NASA lunar missions, commercial space transportation and eventual Mars exploration.
Starship Orbital Launch Pad Project at Starbase, Texas
Reported December 6, 2021 – With the approach of the first orbital flight of Starship, Orbital Launch Pad project at Starbase, Texas, is being constructed to launch readiness. Over a year of development there comes various complex’s elements to the verge of ushering the most powerful rocket in history.
Tank Farm
The tank farm contains a water tank and seven others for different commodities. Three of the tanks contain liquid oxygen (LOX), two contain liquid methane (CH4), while the remaining contain liquid nitrogen (LN2).
Additionally, there are two horizontal CH4 tanks on the main tank farm side but their exact size is not known. The water tank is just a huge cylinder made up of stainless steel rings. The other seven are double-walled cladded with insulation between them. Reason for this is the holding liquids at cryogenic temperatures.
The inner tanks are constructed almost the same way SpaceX constructs the 9-meter diameter ship and booster tanks with rolls of 304L stainless steel. The tanks are required to withstand constant pressurization and depressurization every time, hence the extra reinforcement.
The outer shells, having 12 meters wide, are constructed with stainless steel rings. They were also painted white to protect from thermal heating and corrosion. To help insulation on inner tanks and maintain the cryogenic liquids below the boiling point, the space between the shell and tank is filled with the perlite insulation. Perlite insulation is an inorganic material with a great thermal properties which doesn’t support combustion.
Launch Mount
The launch mount is the place full Starship stack will stand before the launch. It must be able to hold against at least 74.4 MN of thrust.
The mount includes critical components like the hold-down clamps, booster quick disconnect and the water deluge system for sound suppression. The launch table also contains 20 different hold-down clamps. These attach to the bottom of the booster for orbital pad’s static fires and launches. For launches, the hold-down clamps will release the moment all the engines on the booster will be at nominal thrust.
Integration Tower (Mechazilla)
The integration tower will have a distinctive piece of hardware.
Mechazilla, name given by Elon Musk, will be a 145-meter tall integration tower. It will stack the booster and Starship together and hold them during landings. Mechazilla wiill perform this with assistance of two arms which can lift and catch the booster from hardpoints which are between the grid fins. The Starship will also be lifted and caught from hardpoints right on the forward flaps.

Timeline for Starship Orbital Launch Pad Project
June 22, 2020
SpaceX commenced constructing the orbital launch pad with teams attempt to install the concrete rebar for 6 pillars of the orbital launch mount. After constructing reinforcement steel rebar, a steel cylinder was fixed over the rebar and every pillar was filled with concrete and covered to cure.
After the pillars were done, there was no great progress on the Orbital Launch Pad (OLP). Focus was shifted back to flying the SN8 and SN9 vehicles. While the testing efforts on SN9, 10, and 11 were ongoing, SpaceX commenced working on the OLP again. The company started laying the tank farm’s foundations and the associated Ground Support Equipment (GSE) bunkers. They also started the installation of piping for the tank farm.
April 5, 2021
A critical milestone was reached when GSE tank 1 got rolled out and 3 days later lifted onto its mount in the tank farm. Later, during SN15’s test campaign, the building work at the OLP escalated. At this point, SpaceX needed to test the whole stack and not just the ship.
During the surge, GSE 2 was deployed on April 19 and lifted onto its position in the tank farm. On the same day, together with the GSE tanks installation, the foundation for the Integration tower was constructed and the tower’s first steel pillar was added to the foundation.
The dirt berm between the tank farm and landing pad was also being developed before SN15 made the historic flight. When SN15 recovered and retreated to the build site, SpaceX started construction of the OLP. The Quick Disconnect arm and catching arms construction started on the landing pad. Another huge development milestone was achieved when the integration tower roof section was installed on July 28.
August 2021
Three days after the launch table installation, SpaceX rolled Booster 4 (B4). Two days later, S20 was launched for fit checking with the booster interstage and launch table.
After the fit checks were done, B4 was then removed and rolled back to the build site to complete. SpaceX went on working on the Orbital Launch Pad project. This was through adding piping and conduit for the integration tower and the orbital pad.
While fixing all of the needed piping, the quick booster disconnect was installed on the launch table still on 26th August. Quick Disconnect arm was also installed on the Integration tower on 29th. On 22nd September, SpaceX cryo-tested Ground Support Equipment 5 on the tank farm.
October 2021
On October 6, FC lifted the Carriage onto the tooling that was built in so as to assemble the whole system on the ground before installing in the tower.
On 9th October, the first arm was lifted into place by FC. Bucky then lifted the second arm two days later. LOX was first seen loaded into the tank farm on October 17. The final Cryo shell was also sleeved over GSE 2 on October 19, hence completing all the GSE tanks and shells. The Catching system was lastly installed on the integration tower on 20th October.
December 2021
Work remained to complete the Orbital Launch Pad project to a level best for launch operations. The main constituents, however, were in place to help the maiden Starship orbital flight by the following year. The was waiting on pending vehicle readiness and regulatory approvals.
On 3rd December, SpaceX has revealed building a pad for Starship at Launch Complex 39A. This is part of NASA’s Kennedy Space Center in Cape Canaveral.
Late December 2021: Orbital Launch Pad Project at Starbase to be Put to Test
The first orbital test launch of the mammoth rocket ship ever from Earth is set in for January 2022. The Starship test launch will become a pathway back to the moon for the first time after a half a century. It might also be the first spacecraft to eventually land human being on Mars.
It will also be the first spacecraft whose components are fully reusable. This significantly reduces the traditionally astronomic space travel costs. The spacecraft also has unprecedented in-flight refueling capacity, allowing for much frequent and efficient operations.
Starship will be driven into orbit by a first-stage booster rocket named Super Heavy. SpaceX fixed 29 of its Raptor engines before releasing the entire craft to the launchpad at the Starbase launchpad in December 2021.
Furthermore, with around 16m pounds of thrust and a magnitude to carry up to 165 tons from surface of the Earth’s, Starship power is almost twice as that of the Saturn V rockets that propelled 12 astronauts to the moon between 1969 and 1972.
No exact date has been set in January for the Starship’s orbital test launch. This will follow a series of much successful suborbital travels from Texas over the last two years.
If successful, Musk stated that up to a dozen further flights would follow in 2022, with Starship’s first lunar voyage, which is a 2023 space tourism venture funded by Yusaku Maezawa, a Japanese billionaire.
