The prototype ship Starship codenamed SN4 successfully tested with a single engine Raptor. Last tests SpaceX conducted in mid-April — then still a prototype SN3 fell apart during testing under pressure. The company was able to resolve the problem, SN4 Starship passed this test, as it became known today that a rocket tested with the engine running. Of the test results in his Twitter said Elon Musk, who all this time watching the progress of the operation (apparently, to separate only in the hospital, because the Mask had just had a baby).
The test flight of the Starship
The burn engine SN4 was originally scheduled for may 5, but it was canceled a few seconds after the start. Those who watched the stream online, announced the blaze of fire which happened in fraction of seconds after starting the engine. Apparently, SpaceX something again modified, and 6 may engine Raptor prototype rocket had a successful launch and a few seconds off in accordance with the programmed algorithm.
Starship SN4 passed static fire

What’s next? As the missile passed the test with the engine now SpaceX wants to have a trial run for 150 meters. In any case, the company has requested from the Supervisory authorities of the States of radio frequency to conduct a test flight to a height of up to 2 kilometers, but with a single engine Raptor rocket will not rise to the mark. For such flights, SpaceX is already building a Starship SN5 — another prototype of the rocket with three engines Raptor, which can fly for several kilometers.
During the next SpaceX tests need to SN4 Starship not only reached a height of at least 150 meters, but carried out a successful landing on a specially prepared for this site. Even if the engine will work the same as on the tests, not the fact that the landing will be good.the company Elon musk in recent years, this all became much better.
Why Elon Musk is building another rocket
SpaceX is engaged in the development of the spacecraft Starship for fast delivery of people in a distant city, as well as to Mars and other planets. The first assembled prototype of the vehicle was introduced in early 2019, and since then the company managed carefully to test it. Nevertheless, SpaceX is constantly there are any problems with this vehicle. In July 2019 Starship couldn’t get off the ground, and after a few weeks again caught fire during testing. Then Elon Musk said that soon will fix it, and after a couple of months there will be a flight of the ship, but in 2019 it never took place.
So look test firing of the engine Starship
When you run Starship
The subsequent launch was scheduled for the 1st quarter 2020, but, as we have seen, did not take place — the role was played by the pandemic and coronavirus induced quarantine. The company now plans to launch the first official launch of the Starship in 2021. To complete all tests and collect the final version of the aircraft to the planned date, the developers build a new prototype vehicle ship. It is believed that the parallel design of the ship in two different places markedly hasten the day when he will be able to soar into the sky.
He now SpaceX and Elon Musk spending billions of dollars on this project (and when developed two rockets, the money you need is two times more), but the Mask does not regret the money spent. In his opinion, one of the ways our salvation is a space exploration and migration to other planets. What threatens the planet now? Most likely, Elon Musk has in mind the problem of global warming and pollution of the planet with plastic waste.
According to the plans of Space X, the cost of fuel for the starship should be about 900 000 US dollars for one spin. And operating and depreciation expenses add to this amount approximately 1 million and 200 thousand “American presidents”. Thus, the final amount should be about $ 2 million per flight into orbit.
