The MIYOKA (Microgravity Lead-Free Soldering Experiment) Phase-2 experimental hardware, developed by TÜBİTAK Space Technologies Research Institute, has been successfully delivered to the International Space Station (ISS) as part of the SpX-34 Commercial Resupply Mission carried out under NASA’s Commercial Resupply Services (CRS) program in partnership with SpaceX.
Within the scope of the mission, the Dragon capsule was successfully launched aboard a Falcon 9 rocket from Cape Canaveral, Florida, on May 15, 2026. Following approximately one day of orbital insertion and rendezvous operations, the Dragon capsule autonomously docked with the International Space Station on May 16, 2026, successfully completing the docking phase of the mission.
The MIYOKA Phase-2 experimental hardware transported to the ISS aims to investigate the behavior of lead-free soldering processes in a microgravity environment and contribute to the development of technical knowledge for future in-orbit maintenance, repair, and manufacturing activities.
The sustainability of electronic systems in the space environment is of critical importance, particularly for long-duration human space missions, lunar missions, and deep space operations. In this context, the data to be obtained from the MIYOKA experiment is expected to provide significant contributions to research on in-space electronic manufacturing, maintenance, and repair technologies.
The experimental hardware and operational procedures developed by TÜBİTAK UZAY had previously undergone rigorous testing and verification processes in accordance with the safety and compliance requirements for human space missions. The successful delivery of MIYOKA Phase-2 to the ISS marks an important milestone that further strengthens the Institute’s technical capabilities in the fields of microgravity research and technologies for human space missions at an international level.
Throughout the mission, key milestones — including the Falcon 9 launch, orbital footage of the Dragon capsule, ISS approach maneuvers, and docking operations — were broadcast live. With the successful docking of the Dragon capsule to the ISS, the safe delivery of the MIYOKA Phase-2 experimental hardware to the station was officially confirmed.
