Satellite-based magnetic field measurements make global surveys practical for both field modeling and for the mapping of large scale crystal anomalies. They are the only practical method of accurately modeling the global secular variation. Magsat is providing a significant contribution, both because of the timeliness of the survey and because its vector measurement capability represents an advance in the technology of such measurements. Data from Magsat is available for any interested user through the National Space Sciences Data Center at GSFC. With the success of Magsat, future missions should take two courses. Field modeling requires periodic surveys, but not low-altitude measurements as required for crustal studies. On the other hand, further advances in satellite crustal studies will rest NASA's ability to orbit magnetometers at still lower altitudes, concepts for which are still in the state of discussions as to their feasibility.
