Musk mentioned on the same day that Tesla has a good relationship with China, which is the location of the company's largest automobile factory < p > extended reading: < / P > < p > < / P > < p > musk said that Tesla's CEO title is meaningless: it has been changed to "technoking" < / P > < p > source: surging news < / P > < p > < / P > < p > recently, musk said at the CEO Council forum of the Wall Street Journal that the CEO is a false title. He has changed his title at Tesla to "technoking", which has been officially approved. It is reported that the word "technoking" is composed of "techno" and "King". Techno is a genre of electronic music. Musk himself is also an electronic music lover < p > extended reading: < / P > < p > roll up! Musk lied that SpaceX was going bankrupt just to encourage employees to work overtime < / P > < p > source: times finance < / P > < p > picture source: visual China < / P > < p > Wen / Xu Dan < / P > < p > when musk was busy preparing to immigrate to Mars and sell real estate, his aerospace company space X came out with a bankruptcy crisis < p > recently, Elon Musk, CEO of American space exploration technology company (SpaceX), said that there was a crisis in the production of the "Raptor" engine of the star ship. If SpaceX could not achieve the biweekly flight frequency next year, the company might face the risk of bankruptcy < p > but this time, musk didn't send a big twitter to explain this. Instead, he sent an internal letter to the employees of space X on Thanksgiving, calling on them to come back to work: < / P > < p > "Unfortunately, the production crisis of Raptor is much more serious than it looked a few weeks ago. With our in-depth investigation into the problems after the resignation of former senior managers, the problems are much more serious than reported. There is no way to whitewash all this." < / P > < p > "I planned to have a rest this weekend. This is my first rest in a long time, but now I can't. I will be on the Raptor production line all night and all weekend this week." < / P > < p > "Frankly, we need everyone to recover from this disaster unless you have important family affairs. < / P > < p > for SpaceX, if we can't make enough raptors, we can't launch star ships, which means we can't launch Starlink satellite V2 (the previous Falcon engine can't support the volume and mass required to launch V2) < / P > < p > in addition, we are increasing the production speed of star chain terminals to millions of units per year, which will consume a lot of money. These terminals will be useless unless star chain V2 will run in orbit to meet bandwidth requirements. " < / P > < p > according to foreign media reports, due to the slow progress of Raptor engine production, three senior executives of space X have left office. < / P > < p > SpaceX has been reported to go bankrupt for many times, but it has survived safely every time. Does this bankruptcy crisis come from harmony? Is it true, or is musk exaggerating? < / P > < p > why Raptor engine is so important? < / P > < p > in the internal letter, Ma Sk clearly pointed out that the lack of production of Raptor engine led to the bankruptcy crisis of SpaceX. < / P > < p > engine is the heart of all rockets, and each rocket company needs to master independent engine technology, and Raptor engine can be said to be the integrator of space X innovation. It selects liquid oxygen methane with high specific impulse, low cost, low carbon deposition and suitable for reuse as engine propellant , is the fourth largest active liquid rocket engine in the world. < / P > < p > for SpaceX, the advanced Raptor engine is no different from a "money making machine" and carries all the hopes of SpaceX's profit. < / P > < p > Raptor engine is mainly used for starship "star ship" , its main task is to go to the moon or Mars, which needs to transport a large amount of equipment, food and a team of up to 100 people. In addition, the more realistic and urgent task undertaken by the star ship is to launch SpaceX's type 2 (V2) "star chain" Internet satellite. < / P > < p > launch the star chain Internet satellite, that is, SpaceX's "star link" , the plan plans to deploy nearly 12000 satellites in three orbits around 2024 to provide global high-speed Internet access services through the low earth orbit satellite group, so as to solve the problems of long-distance interconnection delay and remote areas, navigation and aviation network coverage. < / P > < p > the star chain plan has always been regarded as the main source of profit for SpaceX in the future. Musk predicts that every month of the star chain in the future In, it will generate up to $30 billion in revenue, which is about 10 times the annual revenue of the rocket business. SpaceX's valuation of up to $100 billion is largely based on the communication and service capabilities formed by the star chain. < / P > < p > however, at this stage, the Star chain is still burning money. SpaceX has launched more than 1600 type 1 (V1) "star chains" using its "Falcon" 9 rocket Satellite and about 100 more advanced type 1.5 (v1.5) satellites. However, the currently launched satellites have weak functionality and no communication capability between satellites. All communications still need to transmit signals to the ground to complete interconnection. < / P > < p > at the end-user level, "star chain" The price of the beta version of the service is US $99 per month, and the equipment required by customers to connect to the satellite is US $499, but the cost of each terminal hardware is close to US $1300. This means that SpaceX will lose about US $800 per user. < / P > < P > therefore, SpaceX places its hope on the type 2 satellite that needs to be launched by the star ship. The carrier capacity of the star ship is larger than that of Falcon 9, and it can make one The first-class and second-class satellites will be recovered, and the launch cost will be further reduced, so that they can be profitable. < / P > < p > the star chain has more than 70000 active users. According to the plan released by musk at the world mobile communication conference in June this year, it is hoped that the number of users will exceed 500000 in the next 12 months. In addition, the internal letter mentioned above indicates that the launch frequency of star ships will reach 100000 next year Once every two weeks. < / P > < p > the Starship weighs 5000 tons. If you want this kind of spacecraft to take off successfully, you must be equipped with 39 Raptor engines. In other words, to realize Musk's wish, SpaceX needs to deliver 78 Raptor engines every month. < / P > < P > if the engine is not produced in mass, it will go bankrupt? Insiders: exaggerate < / P > < p > the reality seems not to be enough to support Mars G's ambition. < / P > < p > not to mention starship flight ?
