Space Liberation Front

The Space Liberation Front (SLF), also known as "Splifs," is the collective name for anti-space militant groups of autonomous individuals or covert cells who, according to the SLF Press Office, use "economic sabotage and guerilla warfare to stop the exploitation and destruction of space and the continued neglect of the planet Earth's fragile environment." The SLF was founded in Stockholm, Sweden in 1999, and spread to the rest of the world by 2010. It is now an international organization with actions reported in nearly two dozen spacefaring countries and is widely regarded as descending from the Animal Liberation Front and Earth Liberation Fronts because of the relationship and cooperation between the three movements. Using the same leaderless resistance model, as well as similar guidelines to the ALF and ELF, sympathizers say it is an eco-defense group dedicated to taking the profit motive out of space-based commerce and instead refocusing efforts on restoring Earth's environment as well as halting the exploitation of poorer nations that have become more dependent on richer spacefaring ones. The SLF was classified as the top "international terror" threat to the United States and its allies by the Federal Bureau of Investigation by 2015, and its members are classified as terrorists. Its long-term goal include the complete capitulation of the modern capitalistic order and reallocation of wealth to the poor.

They are the sole responsible party that conducted the 2025 Phobos Incident which completely cut-off the planet Earth from its space-based industry throughout the Solar System and left space-based infrastructure to become more self-sufficient than before. A series of seven refugee convoys were assembled above the Moon shortly after the Phobos Incident and are making their way to habitable locations in other star systems, as of 2027.
