Ongoing Air Leaks Challenge International Space Station Operations
The ISS has been leaking air for 5 years, and engineers still don’t know why 🔗
Persistent air leaks have been an issue on the International Space Station (ISS) for five years, primarily within the transfer tunnel of the Russian Zvezda service module. NASA and Russian officials have differing opinions on the causes and implications of these leaks, with no consensus reached on their severity. Despite attempts by Russian cosmonauts to repair the cracks, the leak rate has increased significantly, prompting a reassessment of the risks associated with the situation. The leaks are now classified at the highest level of risk in the ISS's management system.
What has been the duration of the air leaks on the ISS?
The air leaks have been occurring for five years, since September 2019.
What are the current leak rates from the transfer tunnel?
The leak rate increased to 3.7 pounds per day as of April, after previously rising from 2.4 pounds per day in February.
How have NASA and Russian officials responded to the air leaks?
There is a lack of agreement between U.S. and Russian officials regarding the causes and severity of the leaks, leading to an unclear understanding of the situation.
