  • AFRL SSPIDR – Space Power Beaming

    Space Solar Power Incremental Demonstrations and Research Project (SSPIDR)

    Earth Day 2021 was celebrated with the highlighting of the Air Force Research Laboratory (AFRL) efforts to test, develop and implement space-based solar power to eliminate current supply chain risks and provide power directly to U.S. expeditionary forces.

    The now ubiquitous Global Positioning System (GPS) was originally developed for military applications and has evolved into a multi-use system that is used every day by the general public. The development of space-based solar power is sure to follow a similar path into peacetime use by the entire planet.

    SSPIDR is a series of Integrated Demonstrations and Technology Maturation efforts at the Air Force Research Laboratory (AFRL) Space Vehicles Directorate to address space-based power collection and transmission capabilities.

  • Space Security and Space Solar Power

    ISS030-E-020039 (26 Dec. 2011) — This busy night time panorama was photographed by one of the Expedition 30 crew members from the International Space Station on Dec. 26, 2011. Comet Lovejoy streaks through the star-filled sky just to the right of center. The land mass is the coast of Chile, looking southeast, with several coastal cities in the capital city region near Santiago. A 28-mm focal length was used to record the image.

    “I have often suggested that given humanity’s increasing and irreversible dependence on outer space for daily human needs, space will either be safe for all or for none.”

    Nayef Al-Rodhan

    The future of space based solar power is dependent on solving technical, financial and political issues. Could the security of outer space end up being the most difficult issue of all? Perhaps the collective need of all humankind for a virtually unlimited source of clean energy can be the catalyst for geopolitical agreement on a peaceful use of outer space.

    What will space security look like in 2021?

    The article, published in The Space Review and linked above, summarizes the current positions of the United States, our allies and our competitors in outer space. In a rather ominous summary, the author asks if space will ultimately be safe for all … or for none.

  • Is Space Solar Power Headed for Cislunar Space?

    STS097-376-019 (7 December 2000) — A close-up view of the P6 solar array on the International Space Station (ISS), backdropped against the blackness of space and the Earth’s horizon. The P6 solar array is the first of eight sets of solar arrays that at the completion of the space station construction in 2006, will comprise the station’s electrical power system, converting sunlight to electricity.

    C-SBSP has long believed that space-based solar power (SBSP) hardware should be manufactured in space, away from the deep gravity well of Planet Earth. Perhaps a cislunar application for SBSP will provide the impetus needed for the United States to develop the required space-based mining / refining, space-based manufacturing and space-based assembly technologies.
