Condensation on Fins module on Earth

Condensation on Fins experiment module before heading towards space. The experiment is part of a larger round of tests on heat transfer in gases and liquids.

It all happens inside the new Heat Transfer Host 2 facility, installed on 30 September 2025 after its delivery on the 23rd Northrop Grumman cargo resupply mission to the International Space Station.

The waist-high module sits within the European Drawer Rack-2 as the latest upgrade for the European Columbus laboratory on the Space Station. The facility is working flawlessly, and its design allows for experiments to be slotted in and run autonomously.

Following this first condensation study, the campaign will continue with a Marangoni in films experiment, focused on instabilities in evaporating liquid films.
