After the Successful Docking, At 18:55 Moscow time(15:55 UTC), the hatch opened from the side of the International Space Station, and then at 19:04 (16:04 UTC) - from the Progress spacecraft side.
Cosmonauts carry out air sampling with special gas analyzers, lay inter-modular ventilation ducts, install quick-release screw clamps for joint strength, and proceed to unload urgent cargo materials for biotechnological experiments that require a special storage regime.
