“…Early successes in this area include the ground processing scheduling system (Deale et al 1994) for NASA space shuttle refurbishment and the SPIKE system used to schedule Hubble Space Telescope operations (Johnston and Miller 1994). SPIKE enabled a 30 percent increase in observation utilization (Johnston et al 1993) for Hubble, a major impact for a multibillion dollar mission. Also impressive is that SPIKE or components of SPIKE have been or are being used for the FUSE, Chandra, Subaru, and Spitzer missions.…”

We are pleased to introduce the space application issue articles in this issue of AI Magazine. The exploration of space is a testament to human curiosity and the desire to understand the universe that we inhabit. As many space agencies around the world design and deploy missions, it is apparent that there is a need for intelligent, exploring systems that can make decisions on their own in remote, potentially hostile environments. At the same time, the monetary cost of operating missions, combined with the growing complexity of the instruments and vehicles being deployed, make it apparent that substantial improvements can be made by the judicious use of automation in mission operations.

“…Large space-based observatories like Hubble Space Telescope (HST) and James Webb Space Telescope (JWST) are built to be multi-purpose facilities with a suite of instruments used to cover a broad range of scientific goals. This leads to schedule designs primarily focusing on common factors like observing efficiency 1 , 2 . The more science-case-specific requirements, like determining the best transit to observe during a year, are left for the individual observer to develop and provide manually.…”

“…This leads to schedule designs primarily focusing on common factors like observing efficiency. 1,2 The more science-case-specific requirements, like determining the best transit to observe during a year, are left for the individual observer to develop and provide manually. However, for small satellite (SmallSat) missions, the scientific goals are often highly focused on just one aspect of astronomical inquiry.…”
