Abstract
There are several problems and issues to be re-considered after the mission SL-J in our experiments. They are 1) Long term delay disturbed to keep sprit high from the viewpoint of continuous scientific activityies, 2) Difficulties for the changing the specifications for the experimental devices, such as LIS, LIC, and PMS, 3) how difficult to change the part of configurations for the data acquisitions, such as temporal data downlink dupulications, and 4) how to change the experimental operation on board by specifying the reasonable evidences which has quite scientific meanings. These problems which should be solved in the future mission may be discussed more frequently and more seriously.
