NASA astronauts Neil Menon and ESA astronaut Sophie Adeno successfully completed Spacewalk 98, a 6.5-hour EVA to install a replacement Space-to-Ground Antenna (S-Gant) on the ISS Z1 truss, restoring full communications redundancy. The mission involved complex robotic arm operations, precise bolt installation, and troubleshooting a suit mobility issue, demonstrating high team resilience and technical proficiency.
Key takeaways 4
The S-Gant replacement was a two-phase operation: the first EVA on August 18th removed the failed unit, while this EVA focused on installing the spare from External Stowage Platform 3 and stowing the failed unit permanently.
The EMU spacesuit operates at 4.3 psi compared to the station's 14.7 psi, necessitating a pre-breathe protocol (mask pre-breathe with 100% oxygen followed by in-suit light exercise) to purge nitrogen and prevent decompression sickness.
The installation required meticulous torque specifications (e.g., 19.2-20.2 ft-lbs) and multiple wiggle tests to ensure bolts were flush and secure, highlighting the precision required for critical hardware installation.
A suit mobility issue occurred with Sophie Adeno's left shoulder joint due to a power harness wrapping around the axial restraint; this was resolved by loosening the harness, demonstrating effective real-time troubleshooting.
