Harpoons

Definition

Harpoons are specialized capture devices used in space debris mitigation to snag and secure space debris for removal or deorbiting. These devices can be critical in the effort to address the growing problem of space debris, allowing for precise targeting and retrieval of defunct satellites or other large debris pieces without causing additional fragmentation.
