With the approval of the Federal Aviation Administration, SpaceX prepared a 400-footed super-length star in its ninth-a launch that includes multiple promotions in a wonderful successive aftermath. The failure of the upper stage during Two predecessors In January and March.
Founder of the company Elon Musk Plan to provide a post -launch update for its long -term plans “to make life multi -step”, it is supposed to determine the role that the high heavy stars will play in trips ultimately to Mars. He originally planned to speak before the last launch, but he decided, without explanation, to keep it even after the trip.

The launch of the huge missile, known as the “9:30 pm Airline test”, was targeted at 7:30 pm EST StarbaseOn the coast of the Gulf of Texas.
Plans for the latest SPACEX test trip
The task was distinguished by the first use of the first year that was previously transferred from 23 floors, which returned itself to arrest the giant. Mechanical weapons In the launch tower during the seventh test of the program in January.
In order to launch the last program, the heavy, high -end phase, which operates by 33 Raptor engines fueled by methane, which generates up to 16 million pounds of orientation, will follow the same flight plan as previous missions, and pushing the upper stage of stars from the thick thick atmosphere in the east path towards the strait in Florida.
It is equipped with six Raptor on its own, and it is expected that the 160 -foot vehicle will be separated from the supporter after about two and a half minutes of takeoff, heading to a tropical path without orbit that carries it towards a planned vertical spray in the Indian Ocean.
Meanwhile, the high heavy heavy will use a different way to stir on the trip to the launch site in an attempt to save the defendants. It is also programmed to fly more descent than usual to learn more about the pressure you can bear safely.
“The supporter will try to fly at an angle of higher attack as it descends,” Spacex said on his website. “By increasing the amount of clouds in the atmosphere on the car, the higher attack angle can lead to a decrease in the drop speed, which in turn requires a lower motivation to burn the initial landing.
“Getting data in the real world about how the supporter is able to control his journey in this upper attack corner, will contribute to improving performance on future vehicles, including the next generation of high heavy.”
As a result of high stress tests, the supporter himself will be guided to the beginning in the Gulf instead of trying to capture the launch pillow where the critical infrastructure can be damaged in a landing accident.

The central vehicle will try to repeat the planned tasks in the previous two flights, both of which failed before they can reach their planned paths.
Eight satellites will be released for the Internet in Stamlink to test the publishing system, one RAPTOR engine will be reshaped to test its ability to start operating in space, and multiple heat tiles have been removed to the “stress test” in weak areas and the operating pillow title equipment in place to learn how to stand to the space environment.
Follow the attempt to release two
The scheduled Tuesday’s launch comes following the upper stage of the upper stage of the Starship Championship during the previous two experimental flights, which were born in the amazing shower of burning debris along the flight tracks.
Since then, SpaceX engineers have conducted a large -scale test and have implemented multiple promotions and improvements to reduce similar failure opportunities. Federal Aviation Administration, which Each of the investigations was supervised by failureSPACEX gave permission to follow up with Ift-9 last week after the conclusion of the IFT-8 review.
“The Federal Aviation Administration conducted a comprehensive safety review of Mishap 8 Starship Flight 8 and decided that the company had addressed the causes of the causes of the accident, and therefore, the vehicle vehicle’s vehicle could return to the trip,” the agency said in a statement. “FAA Spacex will be achieved of all corrective actions.”
In each of the previous failures, Movement of commercial airlines On the Florida Strait, the confirmation is no longer awaiting the emphasis on emphasis on the assertion represents a threat. On the ninth flight, the length of the aircraft danger area was expanded from about 1,000 miles to about 1840 miles, and Spacex was required to launch the missile during the peak air travel periods.
Plans of the moon and Mars
The high heavy stars missile is very important to NASA’s landing plans Space pioneers on the moon In the next few years, Musk plans to eventually send humans to Mars.
NASA plans to use a changing changing in Starship as a lunar land in the ARTEMIS program. NASA wants to use its missiles and the crew capsule to transport astronauts to the moon’s orbit, where the SpaceX will wait for their transportation to the surface.

The Trump administration wants to cancel the missile system, NASA space launch missile The future of Artemis programAs is currently imagined, in doubt. For his part, Musk argued that the United States must pass the moon’s tasks, which was called “distraction”, and instead he went directly to Mars.
However, the high heavy stars missile is expected to play a major role in exploring space in the future, regardless of the target. But there will be a successful multiple test trips to show the safety and reliability necessary for the astronauts and passengers who go to the moon or Mars or outside.
Spacex made changes after catastrophic explosions
The last two compounds, it was launched January 16 and March 6Both ended with non -relevant catastrophic explosions as they approached the planned sub -chimneys’ paths.
During the January flight, the driver’s leakage in the unaccreditated “attic” over Raptor engines led to sustainable fires that eventually closed all spacecraft engines except for one. I lost the measurement from eight minutes and 20 seconds after its launch, and after a moment, the car separated.
“The most likely root cause of the ship’s loss was determined as a consistent response several times on the trip, which was seen during the test, which led to an increase in pressure on the devices in the payment system,” Spacex said on its website. “Pushing leaks exceeded the ability to vent the attic area in the ship and led to sustainable fires.”
After large -scale ground tests, Spacex made changes to paid feed lines, orientation levels, install additional openings and a new nitrogen cleansing system in the attic to reduce the possibility of a fire.
These reforms seem to be working as expected during the eighth test in Starsp in March, but the upper stage again suffered a catastrophic failure. Spacex said on its website that this time, the vehicle suffered from “the failure of the devices in one of the upper Raptor engines that led to an unintended mixing of fuel and ignition.”
To fix the problem, RAPTORS in the upper stage is now characterized by the new nitrogen cleansing system, improvements to the most strict payment draining system and joints in the main areas. Spacex also develops the improvement RAPTOR engine that will eliminate many failures.
