In the Year of '39 Came a Ship in From the Blue …

After repeated safaris through Federal Aviation Administration red-tape and preposterously pedantic environmental impact assessments, SpaceX has hinted that its Starship-24 and Booster-7 may be nearing operational readiness.

Photos shared by the company on 02 July revealed that crews have nearly finished installing 39 upgraded Raptor engines on the new Starship and its Super Heavy booster.

Differences are observable between Starship 24 and its Starship 20 predecessor, the most notable of which is the addition of a metal framework covering the entire breadth of Starship 24‘s aft section. Probably the framework will support thermal insulation intended to shield  sensitive engine, plumbing, and avionics components.

Both Starship-24 and Booster-7 have undergone extensive cryo-proofing and thrust-simulation-testing, which they survived without major issue.

Cryo-proofing is the process of filling and pressurizing the ships’ fuel-tanks with liquid nitrogen which—though super-cooled after the fashion of the methane/oxygen propellant on which the Raptor engines operate—will neither burn nor explode.

Thrust-simulation-testing uses a series of hydraulic rams to subject the ships to the immense compressive forces they will endure during launch.

Starship-24 could theoretically produce nearly 1400 tons (~3.1M lbf) of thrust at sea level—just shy of twice the thrust of an entire Falcon 9 booster—thereby becoming the most powerful orbital spacecraft in history.

Last month, SpaceX CEO Elon Musk announced that the company’s massive Mars-bound rocket should be “ready to take off” in July. Mister Musk added: “For the first time, there is a rocket capable of setting up permanent bases on the moon and Mars.”

The fully reusable Starship is expected to revolutionize space flight by reducing the cost of successive launches. SpaceX’s multi-use ethos is similarly evident in the company’s Falcon-9 rocket, which reuses its first-stage boosters.

Through repetition and refinement, SpaceX has reduced the production cost of the Raptor V2 to approximately half that of its V1.5 predecessor. Furthermore, the V2 variant—the naming of which speaks to an unconscionable ignorance of 20th Century history—produces 25% more thrust than the V1.5 model.
