The Global Surveyor spacecraft will arrive two months later, enter into a circular orbit, and after a brief check-out period, begin to map and study the planet. The Virtual Data Fair is this month s interesting site. In addition to instructions on how to use the system, the site categorizes information resources according to origin.

All entries have icons attached that describe the types of data and information found on the link.
Virtual Data Fair entries also have an Action Icon that is a quick visual reference to the type of action that can be taken after the link has been followed. For example, one can download or order full resolution digital data, learn about product information, or obtain samples of the data products. The icons indicate what you can expect if you link. The Virtual Data Fair just may provide the link to that elusive data set you were seeking.
