Share with friends and circles of friends with wechat scanning QR code < / P > < p > on April 11, NASA recently signed an agreement with spinlaunch, a space technology start-up, to launch a payload with the centrifuge system developed by the company later this year The suborbital mass accelerator developed by < p > < / P > < p > spinlaunch is essentially a giant centrifuge. Located in the desolate desert of New Mexico, this strange looking facility looks like a giant Yo Yo with a small chimney. Inside the facility is a steel vacuum centrifuge driven by electricity. The rotating arm made of carbon fiber is used to accelerate the rotation of the payload, and the lifting speed can reach 8000 kilometers per hour. Then start the rocket engine at high altitude and finally send the payload into the predetermined orbit < p > human beings have used centrifugal force to throw objects for a long time. The industry also has the idea of using giant centrifuges to throw payloads into the universe and greatly reduce the cost of space launch. But spinlaunch was the first company to put this idea into practice and build a prototype < p > spinlaunch was founded in 2014 to develop an alternative to traditional rockets to deliver payloads beyond the earth's atmosphere. The company completed the first public test of suborbital mass accelerator in October last year, accelerating the vehicle with a length of about 3 meters to nearly 5000 kilometers per hour < p > now NASA has signed an agreement with spinlaunch to test the giant centrifuge later this year as part of testing future satellite launch methods < p > Jonathan Yani, founder and CEO of the company & nbsp; Yaney said: "it's just an idea that it's easier to launch a payload in the game." < p > Yani said that the fuel and structure loss used in this way is less than 30% of that of conventional rocket launch < p > it should be clear that spinlaunch equipment will never be used for manned space launch. The company targets smaller satellites that are cheaper and easier to launch < p > the suborbital mass accelerator in New Mexico is just the beginning. Spinlaunch also plans to build an orbital launch facility along the coast. The orbital mass accelerator is three times the size of the New Mexico suborbital mass accelerator and has the same structure. After the payload reaches the upper atmosphere, it will ignite a small rocket engine to provide the additional thrust required for orbit entry < p > spinlaunch has raised $110 million and the company hopes to conduct its first orbital flight test as early as 2025.
