Heat Transfer Host 2 facility

New Heat Transfer Host 2 facility on Redwire Space facilities on Earth. 

This 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.

It hosts the Condensation on Fins experiment, which was installed on 30 September 2025 after its delivery on the 23rd Northrop Grumman cargo resupply mission to the International Space Station.

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