Spacex published an explanation of the wreckage of the second stage of Falcon 9, which fell on Poland last week. Because of the leakage of oxygen, the expected Diorit Diorbet was not burned.
The second stage, which fell from a task that was launched on the first of February to deploy another 22 curtain satellite in the low -Earth orbit. Although the first stage decline was successful, DEORPIT from the second stage did not happen. On February 19, the theater was introduced unlikely to be controlled by Poland, which led to the illumination of the sky and the deposit of debris in the country.
There were no significant injuries or damage to the propertyBut this was more than good luck.
The incident represents the third time since July last year that the performance of Spacex Falcon 9 in the upper stage was not planned, although only one of these positions resulted in the loss of the mission. In that first case, On July 7, 202420 Starlink Sartllites has been left to be cut off in a lower orbit after the liquid liquid leakage from the upper stage from performing the circular burning. in September Last year, a problem with the second stage of burning Deorbit resulted in the burning of Deorbit who sent the debris to the wrong part of the ocean.
According to to update On the Spacex page for the February 1 mission, it was possible to bear the leakage of another liquid oxygen on this malfunction as well, although it occurred after the spread of the Starlink satellites. The second stage engine is usually sent to the ocean area. However, during the coast stage, the oxygen leakage “which eventually pushed up the body’s body rates was developed.”
Instead of the motor risk lighting, SpaceX engineers chose to organize the car – usually compete for all the drivers and empty the batteries so that there is nothing on the plane to cause the stage to collapse while it is in orbit – and allow it to re -enter it unexpectedly.
The company said that there are no toxic substances in the debris that fell on Poland last week, but it advised anyone who coincides with parts of the second stage to leave them alone and contact the authorities. She said she is working closely with the Poland government for recovery and cleaning efforts. “
Although three accidents in a little more than seven months may seem much, it is also useful to consider the rate in which Spacex launches Rockkets Falcon 9. There have been 10 launch operations so far in February alone.
However, although the first stage of the missile is designed to reuse, Spacex must manufacture a new second stage for each launch.
“The teams evaluate the radical cause of the leakage actively and have already implemented a mitigation of future trips,” said Spacex. He did not take the details about what this dilution might be.
With the increase in the frequency of launch in WorkHormse Falcon 9 from Spacex, the higher stage problems are a sign of stress began to appear in the company’s operations. ®
