If SpaceX is going to fly Starships as often as it wants to, it\u2019s going to take more than rockets and launch pads.<\/p>\n

First, there\u2019s the sprawling factory that SpaceX has constructed at its Starbase location along the Gulf Coast in South Texas. The building, known as Starfactory, is designed to produce one Starship per day. A couple of miles to the east, SpaceX has built one Starship launch pad and is preparing to activate a second one.<\/p>\n

With Starship, SpaceX seeks to buck the old way of doing things. Tanker trucks have traditionally delivered rocket propellant to launch pads at America\u2019s busiest spaceports in Florida and California. SpaceX has used the same method of bringing propellant for the first several years of operations at Starbase.<\/p>\n

But a reusable Starship\u2019s scale dwarfs that of other rockets. It stands more than 400 feet tall, with a capacity for more than a million gallons of super-cold liquid methane and liquid oxygen propellants. SpaceX also uses large quantities of liquid nitrogen to chill and purge the propellant loading system for Starship.<\/p>\n

It\u2019s not just Starship\u2019s size. SpaceX has the green light from the Federal Aviation Administration to launch Starships up to 25 times per year from South Texas, and is seeking regulatory approval to fly up to 120 times from new launch pads on Florida\u2019s Space Coast. Eventually, SpaceX eyes daily launches of Starship, or even more, as the company deploys a fleet of ships traveling to low-Earth orbit, the Moon, and Mars.<\/p>\n

There are innumerable bottlenecks to achieving such a fast launch cadence. One of them is simply a matter of logistics. It takes more than 200 tanker trucks traveling from distant refineries to deliver all of the methane, liquid oxygen, and liquid nitrogen for a Starship launch. SpaceX officials recognize this is not an efficient means of conveying these commodities to the launch pad. It takes time, emits pollution, and clogs roadways. The sole two-lane highway leading to Starbase from nearby Brownsville, Texas, is riddled with potholes and cracks in the pavement from overuse by heavy trucks.<\/p>\n

On-site, out of mind<\/h2>\n

SpaceX\u2019s solution to some of these problems is to build its own plants to generate cryogenic fluids. The company recently received approval from local authorities to build an air separation plant across the highway just north of the Starbase launch pads. Construction of the plant began this summer. Once operational, this facility will take in air, condense it, and separate it into oxygen and nitrogen. The resulting liquid oxygen and liquid nitrogen will flow about 1,000 feet through a pipeline into ground storage tanks at the launch site.<\/p>\n

But the air separation plant will only partially solve the propellant bottleneck. SpaceX still needs methane to fuel the 39 (eventually 42) Raptor engines that power the rocket\u2019s Super Heavy booster and Starship upper stage. The answer to this problem is a pair of methane liquefaction facilities to convert natural gas\u2014initially delivered by truck or a future pipeline\u2014into pure liquid methane, and eventually, a methane generation plant co-located with Starbase\u2019s dual launch pads.<\/p>\n

SpaceX has flirted with the idea of propellant generation plants at Starbase before, but this is the closest the company has come to making it a reality. A public notice released by the US Army Corps of Engineers on August 27 describes SpaceX\u2019s plans, and an accompanying map illustrates the changes coming to the Starbase launch site.<\/p>\n

The corps is seeking public comments on SpaceX\u2019s proposals. The corps says SpaceX\u2019s proposed expansion covers approximately 21 acres, including 18 acres of undeveloped \u201cemergent wetlands\u201d and \u201cwind-tidal flats\u201d about a quarter-mile inland from the beach.<\/p>\n

The expansion would also include new storage areas for propellant and ground equipment, staging pads, internal roadways, and a new security wall around the southern perimeter of the launch site.<\/p>\n

,<\/p>\n

\u201cThe project has been designed to reduce the overall launch area expansion footprint and the proposed wetland impacts by incorporating blast walls throughout the infrastructure expansion, allowing infrastructure facilities to be located closer to the existing launch pads,\u201d the corps wrote in the public notice released last week. \u201cSilt fencing would be installed around the permitted limits of disturbance to minimize erosion and sedimentation impacts to receiving waters and to ensure construction equipment remains within the permitted project limits.\u201d<\/p>\n

Plans for Starship\u2019s future launch pads in Florida, still undergoing environmental reviews, show SpaceX intends to produce its own propellant there, too. The Army\u2019s public notice for SpaceX\u2019s plans at Starbase didn\u2019t include any details on how the air separation unit and methane liquefaction facility will work. But a draft environmental impact statement published by the Federal Aviation Administration last month lays out how SpaceX will bring the on-site propellant generation capability online at NASA\u2019s Kennedy Space Center.<\/p>\n

At first, natural gas will be delivered to the Florida launch pad by truck, and a pretreatment system will remove impurities to produce a stream of higher-purity gaseous methane. Then, SpaceX will chill the gas into a liquid state before pumping it into the rocket. \u201cSurplus natural gas would be used for process work, power generation, or would boil off like a natural gas line venting,\u201d officials wrote in the environmental impact statement.<\/p>\n

The air separation unit will dehumidify, liquify, and separate air into its major components\u2014oxygen and nitrogen\u2014and then transfer it into storage tanks. Residual nitrogen, oxygen, and argon gases would be vented back into the atmosphere.<\/p>\n","protected":false},"excerpt":{"rendered":"
