Key facts

The Russian segment of the ISS had been experiencing leaks for approximately five years.
NASA and Roscosmos are actively involved in monitoring the situation.
The cessation of leaks is considered positive news for the Russian space program.
Investigations into the causes and implications of the cracks are ongoing.

Background & context

The International Space Station is a hallmark of international cooperation in space exploration, involving space agencies from the United States, Russia, Europe, Japan, and Canada. Launched in 1998, the ISS orbits Earth at an altitude of approximately 400 kilometers and travels at a speed of about 28,000 kilometers per hour. It serves as a unique laboratory where scientific research is conducted in a microgravity environment, enabling advancements in fields such as astrobiology, astronomy, and physics. The ISS has been continuously occupied since November 2000, providing a platform for long-duration human spaceflight and research that cannot be replicated on Earth. The station's modular design allows for the addition and maintenance of various segments, with Russia contributing several key modules. The Russian segment has been crucial for the station's propulsion and docking capabilities. The leaks in the Russian segment posed a challenge to the station's integrity and safety. Addressing these issues was critical to maintaining the ISS's operational status and ensuring the safety of its crew. The resolution of the leaks represents a significant technical achievement and highlights the importance of international collaboration in addressing complex space challenges.
