“…The benefit of using this methodology to predict thermal behaviour is related to increasing flexibility in operations planning, since the current thermal constraints are defined in terms of a limited set of allowed envelopes representing standard science observation profiles (see 10 ). In a broader perspective, we showed that is possible to use new software technologies in the typically conservative space-domain, given that they can contribute to safety in operations and increase science return.…”

Venus Express is a mission of the European Space Agency with the goal of studying Venus atmosphere. The spacecraft has a thermal system that keeps certain instruments within an operational temperature range. This system consumes some of the electrical power available, but it's hard to estimate how much. We propose a Data Mining and Machine Learning model that significantly improves the accuracy of the current predictions in the Mission Planning System. This should allow a safer planning of resource allocation and eventually an increase in science return.
