Historical structures, such as Alexander Graham Bell’s residence in Nova Scotia, often transition into museums or national historic sites to safeguard their legacy for future generations. But how does one preserve a building the size of a football field orbiting 400 kilometers above Earth?
NASA’s official strategy involves deorbiting the International Space Station (ISS) at the end of its operational life, initiating a controlled descent back into Earth’s atmosphere to crash in a remote oceanic location. However, recent legislative proposals in the U.S. government urge NASA to reconsider this approach and explore the possibility of maintaining the ISS in low Earth orbit.
Since 2000, the ISS has hosted numerous astronauts from the U.S., Russia, Canada, Europe, and Japan, serving as a vital space laboratory assembled through multiple space shuttle and Russian launches. Weighing over 400 metric tonnes, it has facilitated a myriad of experiments unique to microgravity environments.
As the ISS nears the end of its service, NASA disclosed plans to decommission it in 2030 and deorbit it in 2031 using a SpaceX-provided rocket to execute a controlled reentry over the Pacific. Nonetheless, some officials, including U.S. Rep. George Whitesides, advocate for further exploration of alternative preservation methods before committing the ISS to destruction.
Maintaining the ISS in orbit poses challenges due to constant atmospheric drag, necessitating regular orbit adjustments to prevent an uncontrolled reentry. Boosting it to a higher orbit requires substantial fuel and raises collision risks with space debris, potentially exacerbating Earth’s orbital debris issues.
Despite efforts to solicit private sector interest in assuming control of the ISS, no viable proposals have emerged, underscoring the challenges of maintaining the aging station. While NASA shifts focus towards lunar and Mars missions, other countries and private entities are developing their own space stations, hinting at a future beyond the ISS.
While proposals to repurpose the ISS exist, the likelihood remains that the iconic space laboratory, with a price tag of $100 billion US, will likely meet its end in a fiery reentry over the Pacific Ocean. The bill introduced by Rep. Whitesides seeks further evaluation of preservation options, emphasizing the complexity of determining the ISS’s fate as its operational lifespan draws to a close.
