DEBRIS MITIGATION

Protecting space environment with Earth's power.

ALE and JAXA collaboratively developed the ElectroDynamic Tether technology equipped on a spacecraft.
Utilizing the force of Earth's atmospheric drag, and the Lorentz force generated by Earth's magnetic field Our technology promptly deorbits a spacecraft after the completion of its mission and prevents it from being debris.
By protecting the orbital environment for sustainable space development,
related technology and industry will further grow and our lives will be enriched even more.
Contributing to facilitate space development and develop scientific knowledge,
we make space closer for all of humankind.

About DEBRIS MITIGATION

Space debris - spacecraft (satellites, rocket upper stage, etc.) that have completed missions or have broken down and can no longer be used that remain in orbit and orbits Earth.
Artifacts in space continue to increase due to active space development.
If the risk of debris collision with an operating spacecraft continue to increase, future space exploration may be hindered.
ALE, together with JAXA (Japan Aerospace Exploration Agency) has developed a space debris prevention device.
Using EDT¹, atmospheric resistance and Lorentz force²
we are further developing the PMD³ technology, a prompt way to deorbit spacecraft after the completion of their mission.

¹EDT: ElectroDynamic Tether
²Lorentz force: Generated by the interaction between the geomagnetism and the current flowing through the tether.
³PMD: Post-Mission Disposal
