Description
A large Dusty Thermal Vacuum Chamber (DTVC) is coming to the European Space Resources Innovation Centre (ESRIC) in Luxembourg. Now in its final stages of manufacturing and testing, it offers the international space community a unique simulator of lunar conditions to advance technology readiness levels (TRL) of subsystems up to TRL7. Following detailed review and identification of technology needs to advance human and robotic exploration of our Moon, European Space Agency (ESA) procured the DTVC as a key enabling technology and the largest of its kind in Europe. The DTVC is being delivered by a European consortium led by Spartan Space, with Haux-Life Support, Maana Electric and ESRIC. It is designed for a lunar testing environment of thermal extremes of -180oC to +160oC and vacuum pressure down to 10-9 mbar and includes a dust dispensing system to deposit regolith simulant onto test items to evaluate the impact of very fine dust, at discrete time points during the testing cycles. The DTVC is fully automated with PLC/SCADA system for remote control and monitoring of operational parameters of chamber and subsystem performance. It includes multiple sensors for temperature and pressure, feed-throughs for power, instruments, control, data and sampling to equip the DTVC with extensive control, monitoring and diagnostic functionality for advanced testing of optical surfaces, solar panel cleaning mechanisms, seals, rotary systems, thermal control surfaces and dust mitigation devices. Future expansion to simulate solar radiation, solar wind and electrostatic behaviour of regolith has been considered. Whilst ESA’s planned program for future DTVC testing is extensive, the facility will also be offered for international participation from industry, start-ups and research institutions. The aim is to maximise utilisation and benefit for the international space resources community. A new building is being constructed, at the Space Campus in Luxembourg, where ESRIC will host and operate the DTVC. Drawing on the support of NASA’s Johnson Space Center in Houston, where a similar DTVC has been in operation for several years, the new building includes facilities for set-up, preprocessing, testing and post-processing with important considerations for safe handling of the large volumes of lunar regolith simulant (dust) that will play a crucial role in testing campaigns. The DTVC will complement the suite of ESA’s research infrastructure for space resources at ESRIC and this paper presents key design features, characterisation and testing protocols for advancing and validating TRL of subsystems.
