If new parts for the EMU suits should be transported to the ISS they may use the Progress cargo space ship. But what about return of used suit parts to ground for refurbishment?
A Progress cargo ship may be used to burn up waste in the atmosphere. The VBK-Raduga capsule was used to return material to the ground but the last flight was 25 years ago.
Is the Soyuz capsule the only possibility to return EMU suit parts to ground?
