International Space Station Faces Final Countdown As NASA Plans Deorbit By 2031

The International Space Station is set to leave Earth orbit in early 2031, ending over three decades of work in space. NASA plans to deorbit the ISS into the Pacific Ocean, closing a major chapter in international cooperation that has included missions by Saudi astronauts.

Jeddah Astronomy Society Director Majed Abu Zahra explained that the ISS is facing both structural and financial pressure. The station was built for around 15 years of use, yet it will have operated for more than 30 years by the end of this decade, far beyond its original design.

According to Majed Abu Zahra, several key ISS systems are now showing technical problems. Micrometeoroid strikes have damaged some parts of the structure. Air leaks are also an issue. These factors have helped push the annual operating cost of the International Space Station to more than $3 billion.

NASA therefore intends to move funding and expertise from the International Space Station to new projects. The agency is concentrating on long-term programmes for the Moon and Mars. These plans include human missions and advanced robotic exploration, using lessons learned from decades of ISS operations.

Since the launch of the first ISS module in 1998, more than 260 astronauts have travelled to the station. These visitors came from a wide range of countries, including Saudi Arabia. Space agencies from the United States, Europe, Russia, Canada and Japan worked together, while managing political differences on Earth.

Majed Abu Zahra highlighted that the departure of the International Space Station is more than a technical decision. The end of the ISS marks the close of an era of shared human effort in orbit. It also reflects a change in priorities, as national agencies and private companies look toward deeper space.

International Space Station ISS scientific legacy and future impact

Long-duration missions aboard the International Space Station have supplied important social and scientific insights. Analysis of life in orbit has shown how people adapt to confined, harsh environments. Experiments on the ISS offered data on health, behaviour and technology, helping prepare crews for possible journeys to the Moon and Mars.

Majed Abu Zahra stated that the conclusion of ISS operations represents more than thirty years of discovery and innovation. The International Space Station also acts as a bridge to a new phase in space activity, where commercial stations and fresh scientific platforms are expected to play larger roles in Earth orbit.

NASA plans to use an American D-Orbit spacecraft, developed by SpaceX, to guide the ISS safely into the Pacific Ocean. This controlled deorbit is scheduled after station operations end in 2030. The manoeuvre is designed to protect populated regions while allowing a planned, predictable re-entry path.

The International Space Station has become a familiar point of light over the Arab world, including Saudi Arabia. As plans progress for its retirement, attention is turning to how its experience, joint missions and scientific results will support future exploration, especially new lunar and Martian projects led by NASA and partner agencies.
