The SPIN

    It'd been three years since the Supersonic Projectile Insertion Network (SPIN) had come online. For much of humanity's spacefaring time, stationary platform-based rockets were the only reliable method to insert payloads into space. Even when they'd reached the reusable rocket milestone, the cost per launch remained in the millions of dollars; cheap for what they'd been accustomed to.

    Everything changed when SPIN came online, though. Launching things into space became magnitudes cheaper with the decrease in the amount of rocket fuel required. Even long-distance continental travel became faster, resembling the frequency and orchestration of traditional airplane travel.

    In the three years since SPIN opened up to government agencies, the network has launched hundreds of satellites and space exploration probes and has now opened up to private sector use. Some initial commercial use cases include space tourism, continental and international travel. As long as entities registered to use the network meet the safety and capability requirements, any person or organization is now free to request use of the network.

    This model of conduct greatly reduces the responsibility of SPIN administration to ensure proper training of users and instead places that responsibility and liability on the users themselves, thus further increasing the cost-effectiveness, and accessibility of SPIN.

    Anyone can undergo private high-gee training and simply submit their certificate as part of the SPIN use requirements. Similarly, any entity desiring to reach any orbit of Earth, or interstellar space need simply submit vehicle specifications and proof of mid-trajectory launch fuel for desired extra-Earth destination.

    SPIN is equipped with three different supersonic centrifugal insertion mechanisms (SCIMs), for Earth-based use cases, Near-space and LOE use cases, and extra-Earth and interstellar use cases respectively.

    Astoundingly, the Earth-based travel mechanisms have exploded in popularity since being opened to the private sector. And already companies are launching more deep space probes than had previously been launched in the past one hundred fifty years. This is truly an exciting time in the history of travel and space exploration, and it's all thanks to SPIN!
