Since the effective satellite-based education and outreach methods has not been clarified so far, we researched satellites in the world and their activities in order to extract essential issues from the viewpoints of successful education and outreach. As the results, we found the following three key points are all required for successful space education and outreach with satellites; "No limit type": the satellite everyone can use, "Participation type": the satellite users can participate in its mission, and "Interaction type": the satellite users can interact each other. Furthermore, as the example to fulfill these key points, we introduce CubeSats, ITF-1 and ITF-2 developed by University of Tsukuba YUI Project, with their missions and activities related with space education and outreach.
