Erlangen High-energy astrophysics space missions have pioneered and demonstrated the power of legacy data sets for generating new discoveries, especially when analyzed in ways the original researchers could not have anticipated.  HEAVENS provides analysis services for a number of recent and important high-energy missions. These services allow user to perform on-the-fly data analysis to produce straightforwardly scientific results for any sky position, time and energy intervals without requiring mission specific software or detailed instrumental knowledge. The ultimate goal is to ensure that the data of the present space missions could be effectively analyzed by everyone and everywhere well after the end of these missions.  By providing a straightforward interface to complex data and data analysis, HEAVENS also makes the data and the process of generating science products available to the public and higher education.  I will discuss the history and status of HEAVENS and the impact that networking technology can have on mission archiving and operations.
