The document discusses grids and their potential use for data mining applications in Earth science. Some key points: - Grids can connect distributed computing and data resources to enable large-scale applications and collaboration. - The Grid Miner application was developed to mine satellite data on NASA's Information Power Grid as a demonstration. - Grids could help couple satellite data archives to computational resources, allowing users to process large datasets. - For this to be realized, data archives need to be connected to grids and tools developed to enable scientists to access and analyze data.

- In reality, the NASA program in Grids is fairly small compared to the other agencies.
