This community collects and shares material from the joint Russian-German PK-3 Plus Laboratory that was operated on board the International Space Station ISS from 2006 to 2013. PK-3 Plus investigated large homogeneous complex / dusty plasmas under microgravity conditions. Complex plasmas are low temperature plasmas that contain small solid grains / microparticles. It was funded by DLR/BMWi grants no. 50WM1203 and 50WP0203. All publications produced with data from PK-3 Plus need to acknowledge the Roscosmos and DLR space agencies.
