# Chinese Space Station Launches: Anticipated Booster Crash Ahead
Written on
Chapter 1: Launching the Future of Space Exploration
On April 28, the core module of the Chinese Space Station, named Tianhe (Heavenly Harmony), was successfully launched into orbit from Hainan, a southern province of China. This launch, powered by a Long March 5B rocket, marks a pivotal moment in China's ambitious plans for its new space habitat. However, with the launch comes the alert that the rocket booster is expected to crash back to Earth shortly thereafter.
At this point, it is essential to keep an eye on the skies, as the booster is projected to descend uncontrollably.
Section 1.1: The Launch Sequence
The launch saw the massive engines of the Long March 5B rocket ignite, propelling Tianhe into orbit within eight minutes. This core module will serve as the central hub for the upcoming Chinese Space Station, which is set to expand over the next 18 months through ten additional missions orchestrated by the China National Space Agency (CNSA). These missions will include two more crew experiment modules, Wentian and Mengtian, alongside four human flights and four cargo missions.
Just 520 seconds after launch, the rocket's fairings jettisoned, and Tianhe deployed its solar panels, marking the beginning of its decade-long mission in space. Notably, the words "China Manned Space" were emblazoned on the side of the craft.
Subsection 1.1.1: The Booster's Uncertain Path
As the Long March 5B booster, weighing 50 metric tons and measuring 6.4 meters in length, orbits Earth, it is on a trajectory that poses risks of an uncontrolled re-entry. Designated 2021–035B, it currently travels in an orbit of 170 by 372 kilometers at speeds exceeding seven kilometers per second. While much of the booster is anticipated to disintegrate during re-entry, there is potential danger from heat-resistant components, such as thrusters and tanks, surviving the descent and striking the ground.
Section 1.2: The Global Impact
The likelihood of falling debris landing in populated areas is low, but the booster’s orbit does traverse near major cities like New York and Madrid. Should the re-entry occur at night, it may create a spectacular visual event.
Chapter 2: The Vision for the Chinese Space Station
The Chinese Space Station (CSS), once fully assembled, will be approximately a quarter of the size of the International Space Station (ISS), weighing around 66 tons compared to the ISS's 450 tons. It will be capable of accommodating three taikonauts for extended periods and will feature five docking ports for re-supply missions and crew arrivals.
Description: Watch as the booster, part of the Long March 5B rocket, is set to crash into Earth after successfully launching the Tianhe module into space.
The CSS will orbit approximately 210 miles above Earth, situated 20 miles below the ISS, with the capability to adjust its altitude as needed. This initiative is seen as a critical step in establishing a powerful presence in science, technology, and aerospace, according to Chinese President Xi Jinping. The first crewed mission to the CSS, Shenzhou12, is anticipated to launch in June.

A Brief History of Space Stations
The journey of human exploration in space began with the USSR's Salyut 1, the first space station, launched in 1971. Since then, ten other space stations, including the ISS, have been established. Tianhe represents the twelfth space station in this lineage, comparable in size to Skylab and Mir.
In a unique development, the CSS will operate alongside a Hubble-class telescope, the Chinese Space Station Telescope (CSST), which will have the capacity to observe vast swathes of the sky simultaneously. China made its initial foray into human spaceflight in 2003, becoming the third nation to achieve this milestone independently.
The CSS aims to facilitate a variety of scientific experiments spanning fields like physics, chemistry, and biology. Following a call for experiments by the United Nations Office for Outer Space Affairs and the China Manned Space Agency, researchers are expected to explore diverse topics, including microgravity fluid physics and biotechnology.
As the CSS develops, it could expand to include up to three core modules. Despite the lack of publicity surrounding many Chinese space endeavors, this particular launch was accompanied by extensive media coverage and analysis.
