The data from space missions are national treasures. Many of these data are irreplaceable. In solar terrestrial physics data from current missions provide us with state of the art observations with which to address the complex problems of space plasma physics while data from older missions help us place current observations in perspective by providing continuity through time. Data that are prepared so that outside scientists can readily use them have a better chance of being useful years from now than data prepared just for the investigation team. In this talk we will evaluate the state of space physics data activities from the perspective of scientists who were not involved with the data collection. We have asked whether the data meet the needs of scientists today and whether they meet the requirement to provide a long lasting archive. We have evaluated the data from solar terrestrial missions against 4 criteria: 1.) Accessibility- is it easy for scientists to identify and locate the data needed for a given study? Once the data have been located are they readily available to the scientific community? Are they available online or on distributable media? Is needed calibration data readily available? 2.) Documentation- are the data documented so that knowledgeable scientists who are not instrument experts can use them? Does the documentation adhere to recognized standards? Does the documentation explain how the data were collected, and how they were processed as well as the format of the data? Is data quality including sources of contamination carefully documented? 3.) Preservation- is a system in place to assure that the data are not lost? Are the data archived to long lasting media? Are there copies of the data? Is there a program to test and refresh media? 4.) Scaleability- are the technologies being used meeting the demands of today`s users? Are the current data system technologies scaleable to planned data rates from future missions? How are the data systems addressing anticipated data demands?
