Russian cosmonauts to track air leaks with vibration sensors by Staff Writers Moscow (Sputnik) Aug 31, 2021
Cosmonauts will install highly sensitive vibration sensors inside Russian segments at the International Space station in the hope of finding the cause of air leaks, a designer general at the state space firm Energia told Sputnik. Vladimir Solovyov said the "scientific research" would seek to identify "vibration nodes" to see if they coincide with welding seams. He told Sputnik earlier that persistent air leaks were a likely result of welding errors made inside the Zarya and Zvezda modules three decades ago. Cosmonauts were first alerted to a tiny crack inside the Zvezda module at the ISS in 2019 when a drop in air pressure was recorded. Two cracks have been identified and sealed off but air is still escaping the space outpost, albeit at a slower pace. The leak poses no danger to the crew. Source: RIA Novosti
Film and cultures fly on SpaceX CR23 cargo resupply mission Paris (ESA) Aug 26, 2021 Samples of the Biofilms experiment are headed to the International Space Station on the SpaceX CR23 cargo resupply mission this weekend to help maintain astronaut and material safety in space. A common piece of advice of the past 18 months has been to make sure you wash your hands thoroughly. This is because microorganisms are easily spread across common surfaces like door handles and light switches, and it is no less true in space. The Space Station is, after all, a lab as well as a home to astro ... read more
