Carlos Arroyo Ruiz (Universidad Politรฉcnica de Madrid)07/10/2026, 09:00thermal analysis and software tools
Ensuring spacecraft components remain within strict temperature limits depends heavily on the strategic placement and sizing of active thermal control heaters. The industry standard for this design process is manual and iterative, which is not only time-intensive but often results in suboptimal power consumption. Furthermore, while metaheuristics have been proposed for automation, they fall...

Mr Wayne Croisetu (Dorea Technology)07/10/2026, 10:00thermal analysis and software tools
Satellite thermal models are traditionally developed during the design phase and correlated using ground-based thermal vacuum tests. Their primary purpose is to predict temperature extremes under representative worst-case conditions and to demonstrate compliance with the spacecraft thermal requirements. While this approach is essential for spacecraft design and qualification, it provides only...

Lorenzo Rabagliati (OBO Space)07/10/2026, 10:30thermal analysis and software tools
Spacecraft thermal analysis traditionally relies on full scale physical simulations performed with industry standard tools such as ESATAN-TMS and Thermica. While essential for mission verification, these simulations can be computationally intensive, creating a major bottleneck for large-scale sensitivity analyses, design space exploration, and statistical Monte Carlo uncertainty...

Dr Alejandro Fernรกndez-Soler (IDR/UPM)07/10/2026, 15:00thermal analysis and software tools
Post-processing thermal mathematical models is often a bottleneck in the thermal engineering workflow, requiring repetitive manual checks and case-by-case analysis, typically relying on ad-hoc in-house scripts. UPMpyTMD is an open-source tool that reads TMD result files directly and provides fast, interactive post-processing.
The tool enables rapid model checking (node counts, conductor...

Comet Interceptor is a fast-class mission in ESAโs Cosmic Vision Program comprising three spacecrafts. With the challenge of a short development process, it will be the first mission to visit a Long Period Comet that is starting its journey in the inner Solar System. These objects are difficult to target because while detected, a small amount of time remains before leaving again the inner...

Thermal Vacuum Chamber (TVAC) qualification of large-scale hardware such as solar arrays increasingly relies on two-phase liquid nitrogen (LN2) cooling systems to achieve cryogenic transients from ambient to below -180ยฐC. High-fidelity ESATAN-TMS thermo-hydraulic simulation of these systems is computationally expensive, with a single two-phase fluid-network transient exceeding 13 hours of...
