The original software and hardware systems which run the Hubble Space Telescope (HST) Data Archive and Distribution System (DADS) was never designed to cope with the data ingest rates or distribution demands currently placed on the system. The next servicing mission (Spring 2000) will place an even greater load on DADS. We have embarked on a very aggressive, revolutionary, approach to meet the growing demands of and for HST data, and to support future missions, such as NGST. This paper discusses the changes being made, and how they will be done while supporting the current system. The new system will be based upon an OOAD methodology and developed to work in an heterogeneous environment and be platform independent.
