EUROSUIT water-survival test campaign (Marseille)

On July 21, 1961, astronaut virgil Grissom narrowly escaped drowning after the splashdown of his Mercury capsule, which sank only minutes after the hatch unexpectedly opened. The incident had a lasting impact on spacesuit design: ever since, intravehicular spacesuits have also been required to ensure crew survival at sea following an emergency evacuation.

This requirement has been considered from the very beginning of EUROSUIT, the spacesuit project developed for CNES by Spartan Space, in partnership with Decathlon and MEDES.
On June 12, 2026, Spartan Space conducted a major water-survival test campaign in Marseille together with the Marseille Marine Fire Brigade (BMPM). Buoyancy, emergency egress, life raft boarding, and recovery by helicopter or rescue vessel were among the key scenarios evaluated.
This campaign marks an important milestone in the development of an indigenous European crewed spacesuit capability. The results are highly encouraging and will support the next stages of qualification as EUROSUIT progresses toward future European human spaceflight missions.

SPACE-GEL Project

The SPACE-GEL project aims to develop a dual-function aerogel technology for space habitats and spacecraft. This innovative approach utilises titania-based aerogels that provide both thermal insulation and air purification. The photocatalytic properties of these aerogels enable the degradation of volatile organic compounds (VOCs), converting them into harmless substances. By integrating into habitat walls, the technology enhances both air quality and thermal efficiency, while reducing mass and volume compared to conventional systems.

The project is carried out in collaboration with the German Aerospace Center (DLR) and Fraunhofer WKI under ESA contract. In February 2026, as part of the testing and validation phase, a three-day test campaign was conducted aboard Spartan Space's EUROHAB II platform to evaluate the performance of the titania-based aerogels. During the campaign, Spartan Space team members simulated two identical days of activities and performed experiments designed to generate VOCs within the habitat. The tests were repeated under equivalent conditions, with and without the titania aerogel installed, while the Fraunhofer WKI team collected VOC samples at regular intervals throughout the EUROHAB II to support post-test analysis.

The EUROHAB test platform of SPARTAN SPACE allows to simulate a lunar surface habitat and to test life-support-systems in an enclosed environment.
