Russian cosmonauts discovered cracks on the Zarya module of the International Space Station (ISS) and are concerned that the fissures could spread over time, a senior space official reported on Monday (Aug. 30).

"Superficial fissures have been found in some places on the Zarya module," Vladimir Solovyov, chief engineer of rocket and space corporation Energia, told RIA news agency, according to Reuters. "This is bad and suggests that the fissures will begin to spread over time." The Zarya module, also called the Functional Cargo Block, was the first component of the ISS ever launched, having blasted into orbit on Nov. 20, 1998, according to NASA.

Solovyov recently stated that the ISS is beginning to show its age and warned that there could potentially be an "avalanche" of broken equipment after 2025, according to Reuters.

The emergence of these new cracks follows several recent incidents on the ISS. In March, Russian cosmonauts sealed two small cracks — about as wide as human hairs — in the Zvezda module, reported. The Zvezda module contains living quarters for two cosmonauts and supports the station's life support systems, along with backup life support systems in the U.S. portion of the station. The tiny cracks in the module were thought to be the source of an air leak that NASA and Russia's space agency Roscosmos had been investigating for months. 

And in August, the jet thrusters on the Russian research module Nauka unexpectedly fired and pushed the entire station out of place, according to The module had just docked at the station hours before, and when the thrusters suddenly misfired, Nauka essentially tried to pull away from its docking point, pulling the ISS with it.

Russian officials said that a software glitch and a touch of human error likely led to the incident, according to Reuters.
