Calnetix Technologies has announced that their Four Bed Carbon Dioxide Scrubber (FBCO2) high-speed blower system was successfully installed by NASA on the International Space Station (ISS). The magnetically levitated blower system is providing the airflow for the FBCO2 system in a microgravity space environment and has been operating continuously since February 22nd.

"Having our first magnetic bearing blower deployment in space is a great milestone achievement for Calnetix," said Vatche Artinian, CEO of Calnetix. "We are looking forward to building on this success and exploring future opportunities with NASA on utilization of our magnetic bearing systems in space and aerospace applications that challenge conventional bearing technologies."

Calnetix worked with NASA to develop a custom blower system, which includes Momentum, an in-line blower on active magnetic bearings, and Continuum, an integrated hybrid dual controller, to drive the blower. The dual controller consists of an active magnetic bearing (AMB) controller and a variable speed drive (VSD) motor controller in a single compact package that supports speeds up to 60,000 RPM with long-term maintenance-free operation.

Calnetix's Powerflux AMBs were used to provide high speed levitation and reliability, oil-free operation and resistance to particle contaminants in the air stream. The flight hardware components supplied by Calnetix met all the critical design, interface, performance and environmental requirements for a compact and robust blower system.

The new scrubber blasted off to the ISS in November 2022 after extensive ground testing at NASA Marshall in Huntsville, Alabama facility.

Russia will use International Space Station 'until 2028'
Moscow (AFP) April 12, 2023
Russia said Wednesday it planned to use the International Space Station until 2028, an apparent reversal of an earlier announcement to quit the orbiting laboratory after 2024. In July last year, Moscow said it was leaving the International Space Station "after 2024" as ties unravelled between the Kremlin and the West over Moscow's military intervention in Ukraine. On Wednesday, the head of Russian space agency Roscosmos, Yuri Borisov, said Moscow's participation in the international space proje ... read more
