Smaller upper stages often perform deorbit burns to lower altitude to reduce time in orbit and lower chances of collisions with other spacecraft or to immediately reenter the atmosphere. Most expendable rocket first stages do not reach orbital velocity, instead reentering the atmosphere soon after launch and falling within a predefined, uninhabited reentry zone.

The false equivalence was also echoed in online comments by some displeased with the coverage of the reentry, juxtaposing headlines from the Chinese 5B first stage coverage with reports following the reentry of a SpaceX Falcon 9 second stage over Washington state in March after a Merlin engine was unable to restart and effect a reenter over the Pacific Ocean.

In the case of the Long March 5B core stage it is, exceptionally, both. Wang stated that it was “common practice across the world for upper stages of rockets to burn up while reentering the atmosphere,” either intentionally or otherwise obfuscating between first and upper stages. White House press secretary, Jen Psaki, said Wednesday that the “United States is committed to addressing the risks of growing congestion due to space debris and growing activity in space and we want to work with the international community to promote leadership and responsible space behaviors.”Ĭhinese media remained largely silent on the event until after a May 7 foreign ministry press conference in which spokesperson Wang Wenbin said China is following the event closely and stated that the likelihood of damage to aviation or ground facilities was “extremely low.” Major media covered the story intensely in the days before the reentry, reporting on aspects including potential timing and location, international law, previous large uncontrolled reentries such as Skylab and Salyut 7, with the uncertainty of timing and location likely a factor in the widespread interest. While most of the stage was likely to burn up, components made of heat resistant materials, such as tanks and thrusters made stainless steel or titanium, can reach the ground.

Variables such as atmospheric fluctuations meant reentry prediction windows spanned days earlier in the week, and narrowed in a two-hour window around four before expected reentry. Space Force’s 18th Space Control Squadron ( 18 SPCS ), EU Space Surveillance and Tracking ( EU SST ), the Aerospace Corporation and others provided regular reentry prediction updates as the orbit of the rocket stage decayed. The size of the stage, travelling at 7.8 kilometers per second and orbiting once every 90 minutes between 41.5 degrees north and 41.5 degrees south latitude, quickly became a matter of both space industry and public interest.Ĭlaimed observation from Oman which if genuine would imply the reentry was underway with impact over the Indian Ocean While the 22.5-ton Tianhe core module used its own propulsion to raise its orbit, the orbit of the first stage began to decay due to atmospheric drag.

Unusually for a first stage the rocket body had entered and remained in orbit following launch, and would become one of the largest instances of uncontrolled reentry of a spacecraft in decades.

The Long March 5B successfully launched China’s first space station module directly into low Earth orbit April 28 Eastern. Sightings and videos were posted on social media platforms May 8 as the rocket begin its last orbits around the Earth.
