A Falcon 9 rocket launched by SpaceX in recent weeks created a fascinating light show in Oregon, USA. Rocket debris entering the atmosphere from an unexpected location revealed moments similar to a meteor show in the sky.

Speaking to NBC, Washington University astronomer James Davenport said, “Thanks to SpaceX, we had the opportunity to watch a very good show tonight. These remains belong to the upper part of Falcon 9, which we call the secondary stage. In fact, it was launched about three weeks ago and successfully placed a satellite into orbit as expected. . ” used the expressions.

Stating that the rocket has been waiting to fall in orbit for three weeks, Davenport said, “It was the rocket’s only failure in the mission to complete its firing to enter the atmosphere. Therefore, it did not fall from the anticipated place. It has been waiting to fall for three weeks, and today it came directly to our luck.” He spoke in the form.

In fact, it is common for such rocket or old satellite remains to enter the atmosphere from orbit at unexpected positions. It is very difficult to predict entry positions due to the velocities of objects and the headwinds in the upper atmosphere. For example, the remnants of the rocket in the video were moving at a speed of 27 thousand kilometers per hour. However, the objects in question do not pose any danger since they are mixed with ashes at heights of about 60 kilometers from the surface.

Astronomer Jonathan McDowell, who made some statements on the subject, said that the Falcon 9 second stage we saw in the video was the 14th object with a mass of 1 ton or more that entered the atmosphere only this year (since January 1).

SpaceX only reuses the first stage of the rocket on its Falcon 9 rocket. The second stage, on the other hand, enters the atmosphere shortly after it orbits with the load it carries and mixes with the ashes. The Falcon 9 rocket is therefore considered to be partially reusable rockets. SpaceX, on the other hand, has the goal of achieving full reusability in the future with its new generation rocket Starship.

Elon Musk had previously said that the first reused phase of the Falcon 9 accounts for 60% of the total cost of the rocket.
