![]() spread, and what might re-enter and survive, versus what not, those are the things that are the unknown," he said. "It's predictable that the thing is going to decay but exactly how and where will the debris. The debris falling from the sky Thursday night was somewhat expected because it had been up for a couple of weeks, slowly decaying in its orbit. Space Command have developed and maintained a catalogue of the anthropogenic space objects and try their best to predict when two of these objects might come close to each other to collide, and warn people. So whenever they die, they rain down on the space stations, Jah said.īut is it possible to predict these events beforehand? You could just say that these unscheduled events are part of the statistics," he added.Īccording to him, there are currently over 26,000 anthropogenic objects in space, of which about 3,500 are currently serving a purpose while everything else is garbage.Ī lot of the satellites that are put into earth's orbits are orbiting above the earth's space stations. "The business of conducting space operations, by and large, it's actually quite successful and these things do happen and it's statistical. (Reuters)Įvents like these educate the public on the realities of doing business in space and Jah says it's surprising that equipment doesn't fail more often. Jah added that there’s no way to really predict where the debris and decaying materials from rockets might re-enter. Given that most of the earth is covered by water and the largest body of that is the Pacific, things that survive reentry, by and large, basically pollute the ocean," he said. "There's so much uncertainty when things hit the atmosphere. Jah said larger objects are more likely to not fully burn up in the atmosphere, especially if the angle of reentry is not steep enough. utit Web The Falcon Heavy second stage is the same as a Falcon 9. Moriba Jah, an associate professor in aerospace engineering at the University of Texas at Austin, says the rocket was supposed to "slow itself down in calculated way to force it to re-enter and burn up in the atmosphere."īecause that controlled, scheduled, manoeuvre did not happen, it was left to mother nature to clean it up which is unpredictable. with moon SpaceX tracking camera captures epic video of Falcon 9 rocket mb. It created a fake meteor shower in the process. National Weather Service in Seattle has said there is not expected to be any impact on the ground. Debris from SpaceX rocket caused a light show over Seattle and Portland The Falcon 9 rocket was sending Starlink satellites into near-Earth orbit. Jonathan McDowell, an astrophysicist at Harvard University, tweeted that the cause appeared to be the remains of the second stage of a Falcon 9 rocket used by SpaceX to launch a satellite earlier this month. There were no immediate reports of damage, with NWS Seattle saying there were no expected impacts on the ground.Duration 0:57 Featured VideoObservers in B.C., Washington state and Oregon captured what is believed to be the remains of a rocket used by SpaceX. McDowell tweeted that while "we could predict this rocket stage would re-enter today", the speed at which it was travelling meant it was difficult to predict where it would be seen. "The Falcon 9 second stage from the Mar 4 Starlink launch failed to make a deorbit burn and is now re-entering after 22 days in orbit," he tweeted, referring to a rocket launched on March 4 to carry 60 Starlink internet relay satellites into orbit.Ī deorbit burn is a firing of a spacecraft’s thrusters to slow the vehicle and begin its descent, according to NASA's website. Jonathan McDowell from Harvard's Center for Astrophysics also pointed to the Falcon 9 rocket stage as the source of the firework-like display. NWS Seattle said the sight was more likely to be caused by space debris rather than a meteor or similar object because the latter would be moving far faster, a conclusion backed up by several meteorologists quoted by local media. Local media reported multiple sightings just after 9 pm local time, with videos posted online from Washington state and Oregon.
