In reality, it was likely the death spiral of a SpaceX rocket, experts said."The widely reported bright objects in the sky were the debris from a Falcon 9 rocket 2nd stage that did not successfully have a deorbit burn," the Seattle branch of the shortly after the event. "Based on the observed video, this looks more likely than a bolide meteor or similar object, as they would be moving far faster on impact with our atmosphere." (A bolide is a bright meteor that is often called a fireball, according to NASA.)Cornelius Or. pic.twitter.com/QrLfbnUGCBAccording to, the debris likely came from a Falcon 9 rocket that launched on March 4 to put several into orbit. (Starlink is a constellation of more than 1,000 internet satellites being constructed by SpaceX; the constellation will eventually include more than 30,000 satellites.)As Live Science, Falcon 9 rockets reach the atmosphere thanks to two main boosters, or stages. The first stage, which houses nine engines, lifts the rocket off the launch pad; eventually, the first stage decouples and can be steered remotely back to a SpaceX ship for reuse (sometimes that part).The second stage, which contains a single engine, guides the rocket into orbit, then is usually left to decay in the atmosphere, becoming one more piece of.According to McDowell, the second stage of the rocket that launched on March 4 "failed to make a deorbit burn" after launching the Starlink satellites, meaning it didn't come down where it was expected to. After three weeks of drifting in the atmosphere, it finally came down on Thursday, breaking apart in a spectacular explosion.RELATED CONTENTThe NWS stressed that there is no risk that any of those fiery pieces of debris made it through the atmosphere to cause damage. And according to McDowell, big pieces of space junk burn up in our atmosphere more frequently than you might think."This is the 14th piece of space junk with a mass over one tonne [1.1 tons] that has reentered since Jan 1st this year,". "In other words, about one a week. Plus lots more smaller bits of course."Originally published on Live Science.Stay up to date on the latest science news by signing up for our Essentials newsletter.Thank you for signing up to Live Science.
