Abstract: While the long-term preservation of scientific data obtained by large astrophysics missions is ensured through science archives, the issue of data analysis software preservation has hardly been addressed. Efforts by large data centres have contributed so far to maintain some instrument or mission-specific data reduction packages on top of high-level general purpose data analysis software. However, it is always difficult to keep software alive without support and maintenance once the active phase of a mission is over. This is especially difficult in the budgetary model followed by space agencies. We discuss the importance of extending the lifetime of dedicated data analysis packages and review diverse strategies under development at ESA using new paradigms such as Virtual Machines, Cloud Computing, and Software as a Service for making possible full availability of data analysis and calibration software for decades at minimal cost.
