Sky-Watcher in the Pacific Northwest saw an unexpected display of fireworks overhead on Thursday night (March 25).
To Video footage, Slow-motion meteor showers appear to be strafing overhead, with dozens of glowing orbs dragging across the sky with a fiery tail. Experts say it’s actually likely to be the death spiral of the SpaceX rocket.
“The widely reported bright object in the sky was a fragment from the second stage of the Falcon 9 rocket, which was unsuccessful in off-orbit combustion,” said the Seattle branch. Tweeted by the National Weather Service (NWS) Immediately after the event. “Based on the observed video, this seems more likely than a fireball meteor or similar object because it moves much faster in a collision with our atmosphere.” (NASA says. A fireball is a bright meteor often called a fireball.)
according to Harvard Astronomer Jonathan McDowellThe debris probably came from the Falcon 9 rocket launched on March 4th. Starlink satellite In orbit. (Starlink is a constellation of over 1,000 Internet satellites built by SpaceX. The constellation will eventually include over 30,000 satellites.)
As live science Previously reportedThe Falcon 9 rocket reaches the atmosphere thanks to two main boosters, the stages. The first stage, which houses nine engines, lifts the rocket from the launch pad. Eventually, the first stage will be separated and can be remotely returned to the SpaceX vessel for reuse (and in some cases that part). Doesn’t work).
The second stage, which involves a single engine, guides the rocket into orbit, then usually collapses in the atmosphere and becomes another part. Space debris..
According to McDowell, the second stage of the rocket, launched on March 4, did not descend as expected because it “failed to burn out of orbit” after launching the Starlink satellite. After drifting in the atmosphere for three weeks, it finally fell on Thursday and collapsed in a spectacular explosion.
The NWS emphasized that there is no risk of these flammable debris passing through the atmosphere and causing damage. And according to McDowell, large pieces of space debris burn out in our atmosphere more often than you think.
“This is the 14th space debris with a mass of over 1 ton. [1.1 tons] I re-entered Japan from January 1st of this year. “ McDowell tweeted.. “In other words, about once a week. Of course, there are many smaller bits.”
