SKY Perfect JSAT: Development of space debris removal satellite: RIKEN/laser ablation method
-Space SDGs-
Aiming to maintain a sustainable space environment
June 11, 2020
SKY Perfect JSAT/RIKEN/JAXA/Nagoya University/Kyushu University
For the first time in the world, we will begin designing and developing a satellite that removes space debris (space debris such as unnecessary satellites) by the laser method.
This project aims to provide services in 2026.
Space debris removal method:
SKY Perfect JSAT has decided to adopt the laser method*2.
Highly safe because it does not touch
Economical because it does not require fuel to move space debris
RIKEN: “Laser Attitude and Orbit Control Laser Development Research Team”
SKY Perfect JSAT confirmed the feasibility of the technology by conducting a thrust generation experiment*4 with RIKEN and laser ablation*3.
In order to develop major satellite equipment, it was officially merged with RIKEN in April 2020 to formally form the Laser Attitude and Orbit Control Laser Development Research Team.
In collaboration with Nagoya University and Kyushu University, we will proceed with the design and development of laser-borne satellites.
For satellites and ground systems, use the JAXA (J-SPARC) framework.
Role of each participating organization:
■SKY Perfect JSAT:
It supervises the development (movement) service of unwanted satellites using space lasers and the entire satellite development.
■ RIKEN:
In April 2020, the “Laser Development Research Team for Satellite Attitude and Orbit Control” will be set up in RIKEN to develop the laser ablation subsystem, which is the main satellite equipment.
“Laser ablation”
The phenomenon called “laser ablation” is greatly involved in the mechanism of thrust generation by laser irradiation.When a substance is irradiated with laser light, the portion hit by the laser is turned into plasma or vaporized to release the substance. This is laser ablation
■ Japan Aerospace Exploration Agency (JAXA):
Joint implementation of satellite and ground systems through the framework of the “Space Innovation Partnership (J-SPARC)”
■Nagoya University:
Under Nagoya University, which has a proven record in the laser field, we will study the laser irradiation method and reflect it in the development.
■Kyushu University:
Under the graduate school of Kyushu University, which has a track record in the field of space environment, we will study the rotational motion of moving satellites and reflect it in the development.
