Illustrated by the latest drone images from SpaceX's upcoming Boca Chica, Texas facilities, dozens of SpaceXers and local entrepreneurs have gathered at the company's Starship prototype workplace in recent weeks, advancing it from an empty tent and a collection of parts to a handful of big parishes for what seems to be the first full-scale Starship jumper.
Like Falcon 9's Sprinklers and F9R (reusable) jump test articles, this ungainly Starship hopper – standing an impressive 9m 29.5 ft) wide and 40 meters long – is all but guaranteed to be the first integrated BFR hardware to take a flight and hopefully support a productive series of low altitude samples from a roughly prepared South Texas pad.

Since SpaceX CEO Elon Musk took on Twitter to provide a number of updates and images of the company's dramatically reflected approach to BFR (now Starship and Super Heavy), employees and local entrepreneurs have worked almost 24 hours to keep building the first full-scale, integrated Starship test article. Starhopper has been a spectacle and scandal from the beginning thanks to an impeccable visual aesthetic reminiscent of science fiction from the 1950s or an elaborate and slowly burning April Fools prank.
As of now, several dozen tweets and tweets from Musk last week have offered extensive support for the unorthodox new design – replacing column posters and an ablative heat shield for a new stainless steel alloy and floating alloy cooling – while it is clear that the object is taking shape in southern Texas [Stars] is a Starship tractor that eventually reaches the sky on a pillar of the Raptor engine outlet. These initial jump tests may apparently begin as early as March or April 2019. Given Musk's statements, it seems that this very unusual Starship hop test program simply cannot be judged exactly by its cover, at least not easily.
Even for SpaceX, building a space scale prototype of a massive orbital spacecraft outdoors – adjacent to the humid Texan marshland and the Mexican sea spray, no less – is completely and completely unexpected, especially in an industry where rocket hardware routinely manufactured indoors unless in clean room in medical class. The most likely explanation here is that we see something more akin to Aeroshell or the cocoon in a Starship jumper, with a large amount of thoughts and debates that finally land on this oddity as the fastest, most affordable and most computer-rich way forward for full-scale BFR testing.

In this speculative case, the delicate liquid methane and liquid oxygen drive tanks – like the Starhopper's triple-Raptor draft and spaghetti piping – would be manufactured in SpaceX's Hawthorne, CA factory or McGregor, TX test plants before being sent to Boca Chica for integration with the large structures already there. These Raptors, Fuel Thoughts and a general program of customization and customization are next on the list of significant Starhopper-related events that are expected to occur within the next few months.
The latter task has already begun to appear in the form of sheet metal refinement by essentially assembling loose panel holes between and within sheet-covered sections of Starhopper's glossy silvernose. The SpaceX workers also performed the first feature in the fully integrated container base, which was previously built and then placed on top of a finished concrete rack that may or may not have come from a water tank design. While the movement was small, the base and nose portions are now approximately side by side along the apron of SpaceX's temporary tent, where a third Starhopper hull segment is built up.
2019 will be wild and March / April simply can't come soon.
