| Outline of Final Research Achievements |
“Orbital Elevator Satellite” has been developed. It deploys tether on earth orbit in space and a climber translates on tether. At first, the satellite, which can deploy more than 1km tether, was developed, and the numerical simulation and the ground experiment confirmed its mission feasibility. However, it becomes to be difficult for 1km tether deployment due to space debris problem. Then, pico-satellite “CubeSat” (minimized tether deployment scale) was developed and confirmed by the numerical simulation and the ground experiment, and then launched for orbital elevator mission.
