The project main steps


DECLIC is a multi-user facility to investigate low and high temperature critical fluids behaviour, chemical reactivity in supercritical water, directional solidification of transparent alloys, and more generally transparent media under micro-gravity environment on board the International Space Station (ISS).

DECLIC uses the standard infrastructure offered by the EXPRESS rack in the Japanese lab JEM, and uses a standard accommodation in ISS Lockers.

The various types of experiments and possible performances to be attainable are illustrated through selected experiment inserts already developed, which were operated at the beginning of the exploitation phase like:

  • Fluids (CO2, SF6) close to their near ambient critical point engineered in a dedicated insert (ALI) for DECLIC facility
  • Directional Solidification of transparent materials (succinonitrile alloy) engineered in a dedicated insert (DSI) for DECLIC facility providing wide solidification rate range and adjustable thermal gradient
  • High temperature, and high pressure Critical Fluids (H2O, NH3,...) engineered in a dedicated insert (HTI).

In the future, other scientific teams could propose new experiments and new inserts related to transparent materials in the DECLIC facility. No country is a priori excluded.

DECLIC was designed for remote science control, commonly called "Tele-science". Operation capabilities offer scientists the possibility to remotely visualise and modify their selected experiment conditions in the ISS from User Home Base through CADMOS User Support and Operation Centre.

Due to the interest of French and US scientific laboratories to co-operate in these fields of research, DECLIC has become a CNES-NASA co-operative project.

CNES is sponsoring the development of the facility and associated French experiments while NASA is making resources available for ground to orbit transportation, crew time, energy and running time on board the ISS, as well as Telemetry - Tele-commanding for Tele-science operations from the ground.

The initial set of experiment inserts accomplished
the following classes of experiment

Acronyme Reference Name Experiment Type Sample Material(s) Principal Investigator Sponsor
ALI Alice like Insert Near-Room temperature critical fluids CO2, SF6, Xe ICMCB CNES
HTI High Temperature Insert High temperature critical fluids H2O,... ICMCB CNES
DSI Directional Solidification Insert Solidification of transparent model materials Succinonitrile and its salol alloys L2MP CNES
