SpaceX’s first high-altitude starship prototype only passed “cryo-proof” testing


SpaceX CEO Elon Musk says the first high-altitude starship prototype in South Texas – known as the SN8 – is only “cryo-proof” testing, possibly in the near future of ~ 15 km (9.5 mi) of flight testing. Installation of ship for.

Meanwhile, NASA astronaut Bob Haine recently overflowed SpaceX’s Boca Chica, Texas starship factory with several compatriots, in the midst of a significant test-proof expedition to the starship SN8, an excellent aerial view of the company’s bustling facilities Presents.

Hines succeeded in capturing the moon with one of the T-38 trainer jets, which NASA astronauts regularly use for training and travel, serving as a reminder that SpaceX launched a lunar starship Won $ 135 million to create something that could hardly bring humans back to Earth’s lone companions. With or without NASA involvement, the starship prototype production and testing program SpaceX will determine directly between the deepest will when and when the company arrives – and on land – the Moon and Mars.

Over the last three days, SpaceX has slowly put on the starship SN8 – the first prototype is for high-altitude flight testing – via its Pace, with seemingly “cryo-proof” testing on 5/6 October Was started During the first attempt, SpaceX attempted to pressurize the rocket tank section with cold nitrogen gas and possibly a small amount of liquid nitrogen before reopening the highway. The Starship SN8 also carried out its big heft for the first time on October 4 under its own power and SpaceX has conducted many more test trials in the coming days.

24 hours later, SpaceX tried again, this time to successfully load the starship SN8’s liquid oxygen and methane propellant tanks with one thousand metric tons (2.2 million pounds) of liquid nitrogen – of cryogenic celent. Used to simulate ultra-cold temperatures. A catastrophic fire or explosion. After the cryo load, SpaceX reportedly attempted to pressurize the rocket’s tanks to their limits, but the test was halted to a lesser extent when the starship SN8 hit “after reaching a pressure of 7 bar (~ 100 psi).” Near engine leak “ejected a small leak.

In short, as Musk predicted, SpaceX apparently managed to fix a minor leak in less than 24 hours and began the third round of the StarShip SN8 cryo-proof trial late on 7 October. Once again, the rocket was fully loaded with liquid nitrogen and some 2-3 hours were spent under cryogenic stress as SpaceX presumably simulated thrust of the raptor engine with hydraulic ram through thrust structure (“thrust puck”). Used to insist on Nothing out of the ordinary happened and Musk remains to comment on the test, suggesting that things were largely planned.

Apparently, SpaceX prepared for the fourth night of cryogenic testing on 8/9 October. It is not entirely surprising that the company would primarily like to test the first starship manufactured with as much new steel alloys as possible. If the SN8’s fourth night of testing gives satisfactory results and is less than the leak discovered in the second round of SpaceX testing, the company may be ready to install three engines and attempt the first multi-raptor static fire test . sometimes.

Update: SpaceX CEO Elon Musk says starship SN8 The “cryo-proof” test is the most likely to install the rocket for the first triple-raptor static fire test. If the SN8 undergoes static fire testing, it will likely be crafted with a noscan and forward flap and attempt another three-engined static fire using small ‘header’ propellant tanks, ultimately a starship. Is preparing to support the first high-altitude flight test. Prototype if all goes according to plan.
