  Remote sensors on spacecrafts acquire huge volumes of data that can be
processed for other purposes in addition to those they were designed for. The
project TECSEL2 was born for the usage of the Gaia AIM/AVU daily pipeline
output and solar events data to characterize the response of detectors
subjected to strong radiation damage within an environment not protected by the
terrestrial magnetic field, the Lagrangian point L2, where Gaia operates. The
project also aims at identifying anomalies in the scientific output parameters
and relate them to detectors malfunctioning due to radiation damage issues
correlating with solar events occurred in the same time range. TECSEL2 actually
designs and implements a system based on big data technologies which are the
state of art in the fields of data processing and data storage. The final goal
of TECSEL2 is not only related to the Gaia project, because it provides useful
analysis techniques for generic and potentially huge time series datasets.
