- Abstract
There are a lot of space debris in low earth orbit (LEO), that will become a serious problem in the future. We must solve this problem immediately. For the future process of the debris capture system in LEO, it is necessary to grasp shapes and motions of space debris. Generally, a radar observation is usable to investigate them effectively, though it takes many costs. An optical observation is able to assume a state of a satellite with a less expenditure. We are accumulating data on the brightness change of LEO debris continuously. A 35cm LEO satellite tracking telescope of JAXA aerospace research center is used to measure the brightness of a lot of LEO debris. This telescope is mounted on the 3-axial mount that is able to track any type of orbits. A periodical change of the brightness means that the debris is rotating. If such data are collected accurately, they become information profitable for the debris capture in the future. In this paper, we introduce a part of observational data and discuss the feature of the rotational motion of the LEO debris.
