Abstract
Recently, requests for the telescience from the scientists in the space experiment fields have been emphasized. In this paper, the general ideas of telescience, its history, Japan's purposes, the develop ment efforts, and the results of recent testbed experiments are descrived to respond to the emphasized telescience requests.
For the efficient and improved space experiments in JEM, we have continued the telescience technology development effort since 1987. Based on the real space environment experiments on the space shuttle, we have begun the new telescience activities for the initial JEM in 1999.
