The International Space Station (ISS) is heading towards a dramatic finale, destined for a remote and mysterious location in the Pacific Ocean, known as 'Point Nemo'. But why choose this isolated spot for the ISS's final mission? It's a decision that has sparked curiosity and debate among space enthusiasts and experts alike.
By 2030, the ISS will embark on a controlled splashdown in the 'spacecraft cemetery' at Point Nemo, marking the end of its remarkable journey. This carefully selected location is the most isolated point of water on Earth, a fitting tribute to the global collaboration that has sustained the ISS for over 25 years. NASA, Roscosmos, the European Space Agency, JAXA, and the Canadian Space Agency (CSA) have all played a crucial role in this international endeavor.
Point Nemo's name is a nod to the fictional explorer Captain Nemo, a character from Jules Verne's classic novel 'Twenty Thousand Leagues Under the Sea'. The Latin word 'nemo' translates to 'no one' or 'nobody', reflecting the area's remote and enigmatic nature. Located approximately 2,688 kilometers from the nearest land, Point Nemo is a secluded spot in the South Pacific, far from any human habitation or commercial shipping lanes.
And here's where it gets controversial: Why choose such a remote location for the ISS's deorbit? The answer lies in the size and value of the ISS. As large as a football pitch, the ISS contains crucial modules and equipment. An uncontrolled re-entry could pose significant risks, potentially causing harm to people and property. Thus, a controlled dive into Point Nemo ensures a safer outcome.
NASA has tasked SpaceX with creating a 'US Deorbit Vehicle' based on the Cargo Dragon spacecraft. This vehicle will attach to the ISS and initiate a series of maneuvers to guide the station towards its final resting place. The de-orbit process will be carefully orchestrated, with the primary structure and modules separating from the solar arrays and radiators. Most of the ISS will burn up during re-entry, while heat-resistant and dense components will sink harmlessly to the ocean floor.
The end of the ISS era raises intriguing questions: Is this the best way to decommission such a significant space structure? What are the alternatives? As we bid farewell to the ISS, let's explore the complexities of space exploration and the challenges of managing its legacy.
