Inside SpaceX $1.3 Billion Dollar Space Bakery - thermal protection systems - heat shield tiles

Futurity Channel on Youtube shows the SpaceX technologies. Keep watching to find out more about how SpaceX Bakery manufactures the most important parts of their thermal protection systems - heat shield tiles! Subscribe to Futurity for more SpaceX news.

It is interesting: what is SpaceX heat shield made of. The spacecraft's eventual heatshield will be composed of many so-called "hex tiles", hexagonally shaped bits of ceramic shielding designed to dissipate the enormous amounts of hot heat generated during reentry into the Earth's atmosphere.

A Starship would have many heat tiles. There were 20,548 HRSI tiles which covered the landing gear doors, external tank umbilical connection doors, and the rest of the orbiter's under surfaces.

SpaceX certainly does have a useful heat shield. As it prepares for its second human spaceflight mission next month, SpaceX company has redesigned a small portion of its spacecraft's heat shield in addition to making a few other refinements to the Dragon capsule.

The black tiles on the Starship are interesting. The fascinating tiles exposed to reentry temperatures of up to 2,300 degrees Fahrenheit, such as those on portions of the belly, are given a protective coating of certain black glass. Black tiles work by reflecting an amazing about 90 percent of the heat they're exposed to back into the atmosphere, while the tiles' interior 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 while the space capsule plummets through the atmosphere and creates superheated plasma on its return to Earth. "Wear and tear" happens to spaceships - this is an important thing to think about.

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

SpaceX seems to trade on the stock market. The shares trade on the London Stock Exchange. The first of these investment trusts, Scottish Mortgage Investment Trust, has a 0.8% exposure in SpaceX as part of its ticker symbol SMT.

It seems that Google owns some of SpaceX. In January 2015, SpaceX raised US$1 billion in funding from Google and Fidelity, in exchange for 8.33% of the company, establishing the company valuation at approximately US$12 billion.

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

(From Feb. 17, 2021) SpaceX raises $850 million at Elon Musk's favorite price of $420 per share. Elon Musk, Tesla's CEO, owns SpaceX. Elon Musk's SpaceX is now valued at about $74 billion, CNBC reported. The aerospace company raised $1.9 billion in August to help fund its Starlink and Starship projects.

It seems that Musk is still the largest shareholder and the CEO of SpaceX, and the large company is now worth far more than the $100 million that Musk originally invested to form the company.

It seems that the highest paying job at SpaceX is "Senior Software Engineer." The highest-paying job at SpaceX is a Senior Software Engineer with a salary of $247,959 per year.
