Spacelab 1 activities, using the Space-plasma Computer Analysis Network (SCAN), occurred because the network provided a solution to an immediate communication problem. For many investigators, SCAN is an ideal environment for the continued analysis of Spacelab data. SCAN currently provides access to other Spacelab investigators and co-investigators, to Spacelab and non-Spacelab correlative data bases, and to large Class VI computational facilities for modeling. SCAN accomplishes this by linking computers together at remote institutions that are used routinely by space science researchers. The networking software utilizes commercially available computer-to-computer communications. SCAN is a pilot project and a testbed for space science communication which, from the beginning, included the reseach user community in the planning, building and operation of the computer network. Expansion of the network within the next two years will include more than 12 institutions (many of whom are Spacelab investigators). This expansion includes the MSFC Mission Integration Planning System or MIPS which is responsible for generating Spacelab mission timeline and scheduling information for payload functional operations. In addition, Shuttle environment information needed for instrument development is being accumulated at GSFC and will be readily accessable over SCAN. Although the space plasma community is the prime user of SCAN, it is anticipated that along with other pilot systems (planned and operational) in the other space science fields, a unified NASA-wide communication system will ultimately develop from these pilot efforts.
