A circuit board is pictured inside a container system inside the International Space Station

iss075e0103078 (Sept. 14, 2026) --- A circuit board is pictured inside a container system attached to the Harmony module's maintenance work area inside the International Space Station. NASA astronaut and Expedition 75 flight engineer Anil Menon used a lead-free soldering technique to solder components on the circuit board and demonstrate the manufacturing and repair of electronics in microgravity. The MIYOKA experiment will return the space-soldered samples to Earth for analysis and compare them to identical ground-soldered samples. Results may lead to reduced reliance on costly resupply missions.
