The International Space Station (ISS) has been operational since 2000 and is continuously manned by astronauts, orbiting Earth every 90 minutes.
Throughout its operation, the ISS has served as a hub for scientific experiments, space travel research, and international cooperation. Over 280 astronauts from more than 23 countries have visited the space station.
However, as the decade nears its end, the ISS is reaching the end of its functional lifespan, prompting the need to address its future once it’s no longer in use.
Abandoning the craft is not an option due to its size and potential risk to other satellites in orbit. NASA has explored various options, including pushing the ISS higher, but ultimately determined that salvaging parts for historical preservation or technical analysis would be too complex and costly.
Therefore, the only viable solution is to deorbit the ISS. SpaceX, led by Elon Musk, has been awarded an $843 million contract by NASA to develop and deliver a deorbit vehicle for the ISS.
Plans are still being finalized, but the general idea is for the deorbit vehicle to guide the ISS into the atmosphere, where most of it will burn up upon re-entry. Careful considerations will be made to ensure any remaining parts land in uninhabited areas.
With the ISS’s days numbered, the future of space habitation is shifting towards private sector initiatives, such as NASA’s Commercial Low Earth Orbit Development program and the Lunar Gateway project.
Despite the end of the ISS era, experts like Dr. Darren Baskill emphasize the station’s contributions to science, exploration, and international collaboration, paving the way for future advancements in space.
