ALE + Tokio Marine Sign An MoU To Develop Space Debris Mitigation Device Using EDT

March 13, 2022

Tokyo-based ALE Co., Ltd. (ALE) and Tokio Marine & Nichido Fire Insurance Co., Ltd., a major insurance company and domestic leader in the field of space insurance (Tokio Marine & Nichido) have concluded a Memorandum of Understanding (MOU) to cooperate on initiatives to create a sustainable space environment for commercialization of a debris mitigation device using EDT (ElectroDynamic Tether — EDT device).

Both companies are aiming to accelerate the commercialization of the EDT device and create a sustainable space environment.

ALE’s vision is to “anchor space into our culture to empower humankind to new endeavors” and the company aims to contribute toward the sustainable development of the humankind, the range of whose activities may well expand beyond the Earth.

Working toward the realization of this vision, ALE is developing space entertainment, such as man-made shooting stars, that is aimed to spark people’s curiosity; accumulation and use of Earth’s atmospheric data that will enable to help characterize the mechanisms behind climate change; plus the prevention of space debris, the maintenance of the orbital environment and the development of the EDT device that contributes to creating a sustainable space environment.

This MOU will develop the following initiatives while evolving the debris mitigation project in line with ALE’s vision and combining the company’s knowledge and technology about space equipment development with Tokio Marine & Nichido’s expertise in risk management.

  • Examine business feasibility related to EDT device
  • Technological development of EDT device

Tokio Marine & Nichido announced the cooperation in a press release concerning the space project on February 24th at www.tokiomarine-nichido.co.jp/company/release/pdf/220224_01.pdf

Debris mitigation device using EDT (EDT device) — this device aims at space debris mitigation measures and will be loaded onto spacecraft (satellites, rocket upper stage, etc.) before launch and will extend a long tether (EDT) in space after the completion of the spacecraft’s mission. Using the Earth’s magnetic field and atmospheric drag, the orbital altitude is lowered in a shorter period of time and enables the satellite to re-enter the Earth’s atmosphere and burn up.

As part of the JAXA Space Innovation through Partnership and Co-creation (J-SPARC) project, ALE has developed this world’s first PMD (Post Mission Disposal) device using a carbon nanotube electron source and EDT. Due to the recent flurry of space development, it is agreed that if flying objects in space increase, in the near future they will start to collide and space debris will self-propagate and generate in large volumes. As a result, there are concerns raised that there will not only be an increase in risk of destruction of existing satellites but also an adverse effect on planned satellite launches and the use of satellite data, which is becoming a part of the social infrastructure.

In addition, actions are being taken in various countries around the world and by international organizations to impose legal obligations on businesses to implement measures to reduce space debris. Therefore, artificial objects which are going to be launched into space in the future will be demanded to take measures to prevent themself from becoming space debris, and expectations of this device are heightening according to trends in this market and industry.
