Igor B News: Inside SpaceX $ 1.3 billion Space Bakery – thermal protection systems

Futurity Channel on Youtube shows SpaceX technologies. Keep watching to learn more about how SpaceX Bakery makes the most important parts of its thermal protection systems: the heat shield tiles! Subscribe to Futurity for more SpaceX news.

It’s interesting: what the SpaceX heat shield is made of. The spacecraft’s eventual heat shield will consist of many so-called “hexagonal tiles”, hexagonal-shaped ceramic shielding fragments designed to dissipate the enormous amounts of heat generated during re-entry into the Earth’s atmosphere.

A spaceship would have many heating tiles. There were 20,548 HRSI tiles covering the landing gear ports, the umbilical connection ports of the external tank, and the rest of the lower surfaces of the orbiter.

SpaceX definitely has a useful heat shield. As it prepares for its second human spaceflight mission next month, the SpaceX company has redesigned a small portion of its spacecraft’s heat shield as well as making a few other refinements to the Dragon capsule.

The black tiles on the ship are interesting. The fascinating tiles exposed to re-entry temperatures of up to 2,300 degrees Fahrenheit, such as those on portions of the belly, are equipped with a protective coating of some black glass. Black tiles work by reflecting about 90% of the heat they are exposed to into the atmosphere, while the inside of the tiles absorbs the rest.

The useful SpaceX heat shield works in interesting ways. The shield protects Crew Dragon by deflecting and absorbing heat that can reach 3,500 degrees Fahrenheit as the space capsule crashes through the atmosphere and creates superheated plasma upon its return to Earth. “Usury” happens to spaceships: this is an important thing to think about.

SpaceX has 2 interesting rocket test facilities for vertical take-off, vertical landing rockets: the SpaceX Rocket Development and Test Facility in McGregor, Texas and a leased test facility in Spaceport America in southern New Mexico.

SpaceX appears to be trading on the stock exchange. The shares are listed on the London Stock Exchange. The first of these investment funds, Scottish Mortgage Investment Trust, has 0.8% exposure to SpaceX as part of its SMT ticker symbol.

It appears that Google owns part of SpaceX. In January 2015, SpaceX raised $ 1 billion in funding from Google and Fidelity in exchange for 8.33 percent of the company, setting the company’s valuation at around $ 12 billion.

SpaceX rockets use various fuels. SpaceX’s next-generation Raptor engine, which will power the company’s new massive deep-space transportation system, uses supercooled liquid methane and LOX as propellants. The company’s previous engines, Merlin and Kestrel, also used LOX, albeit with refined kerosene rather than methane.

(As of February 17, 2021) SpaceX raises $ 850 million at Elon Musk’s preferred price of $ 420 per share. Elon Musk, CEO of Tesla, owns SpaceX. Elon Musk’s SpaceX is now valued at around $ 74 billion, CNBC reported. The aerospace company raised $ 1.9 billion in August to help finance its Starlink and Starship projects.

It appears that Musk is still SpaceX’s largest shareholder and CEO, and the big company is now worth far more than the $ 100 million Musk originally invested to form the company.

It seems that the highest paid job at SpaceX is “Senior Software Engineer”. The highest-paid job at SpaceX is a senior software engineer with a salary of $ 247,959 per year.
