Elon Musk, CEO of SpaceX, confirmed that the static fire of the first triple engine of the starship and the Raptor was successful, opening the door for the installation of the Nakkon.
CDT, Oct. 20: At 13:33 a.m., Starship’s serial number 7 (SN8) successfully blew up three raptor engines in less than two hours after completing the first successful three-engine preburner test. With zero direct human intervention, SpaceX remotely isolated the rocket’s cryogenic liquid methane and oxygen propellant – the remnants are now too warm to be used in a controlled way again. In less than an hour or so, SpaceX engineers scrambled through the data generated and concluded that all three raptor engines were healthy after their partial ignition tests.
Effectively reset to a stable state, SpaceX re-loads Starship SN8’s propellant tanks with a small amount of supercooled locks and LCH4, almost exactly mirroring the preburner test. About 50 minutes after the start of the recycling and 25 minutes after the start of the propellant load, the Starship SN8 ignites three radiators simultaneously – a milestone for any rocket engine. Static Fire is now complete, becoming the first operational prototype to reach the full 50 meters (~ 165 feet) height of the Starship SN8.
Shortly before confirming the success of the Mask SN8’s static fire, SpaceX canceled a pre-construction stable fire window on October 20 and scheduled several new road closures on Wednesday, October 21. Not to mention the company’s recent stagnant fire, one of which lasted from 9pm to 6am, with SpaceX’s new Wednesday closures scheduled for 7am to noon and local time from 3pm to 5pm local (CDT).
As a little fact point, in the context of Starship SN8’s steady fire success, the closures alone make it clear that SpaceX planned to install Starship SN8’s Nakkon on October 21st. Kasturi confirmed that this was estimated a few hours after the road was closed.
It’s not Absolutely Clearly, however, most observers assume that the window from 12 a.m. to 12 p.m. Wednesday is needed to transport a large, new crane স্প 2 miles between SpaceX’s Boca Chika factory and launch facility. The stacked nose section of the Starship SN8 will probably be installed on the same self-propelled mobile transporters (SPMT) and run on the launch pad from 3pm to 5pm, then the nose will be lifted and stacked on top of the Starship SN8.
SpaceX simply stacked the Starship prototype once and for all when MK1’s nose section temporarily merged into its tank section as the focal point for CEO Elon Musk’s October 2019 Starship event. It’s not clear why SpaceX will not only use mobile cranes hired in the past for starship tank division activities (and MK1 stacking), so it remains to be seen what will actually be used for Wednesday’s road closure.
But SpaceX’s road closure plan will end with a wildcard. Once installed, the plan is to fire the second triple-raptor static while simply drawing propellants from the SN8’s header tanks – small internal tanks designed to hold the landing propellant, one of which is located at the tip of the starship’s nose. . On October 21st and 22nd, SpaceX still has the “SN8 Static Fire” test scheduled for 9pm to 6pm. Filed before the successful stable fire of SN8 on October 20, a possible explanation is probably a common clerical error or miscommunication, Cameron County or SpaceX failing to communicate properly that the next static fire test windows are no longer needed.
If it is intentional to hold off on a steady fire, it means that SpaceX – probably at the urging of Kastur – intends to install the Nakkon of the starship SN8 within a few hours. It is almost inconceivable that the Nakkon of the starship SN8 – multiple gas thrusters, Tesla motor driven forward flaps, a liquid oxygen header tank, vents and plenty of plumbing – could be installed and ready for testing in less than 12 hours. With the exception of a surprising method of mating the SN8’s nose and tank sections, the Naxon will need to be welded to the rest of the SN8 and inspected for inspiration – usually a multi-day process.
Regardless of how quickly SpaceX removes and considering how Dead-Set CEO Elon Musk is on the way to overcoming limitations and breaking obstacles, it seems reasonable that Starship SN8 could be fully integrated and ready for a second static fire test a few days from now. Once finished, the SN8 will be ready to attempt the starship’s first high-altitude flight test, launching an undeclared Skydive-Stein descent and landing 15 kilometers (~ 9.3 miles).
