Stars
Also called Kukai (a famous priest and calligrapher)
Is a pair of tethered satellites built by Kagawa University.
The two units (Ku and Kai) are tethered to each other with strands of synthetic
fiber, and a camera built into the smaller unit is designed to photograph the
other unit in space. The satellite will explore the possibility of using the
technique to examine the outer walls of space stations.
