An orbital ring, also known as a skyhook or space elevator, is a proposed megastructure designed to extend from the Earth's surface into space. It consists of two cables anchored at opposite points on Earth’s equator with one end extending into geostationary orbit (GEO) and the other into low Earth orbit (LEO).
It aims to solve issues related to high launch costs and limited access to space by providing a more efficient means of transporting payloads into orbit and beyond. Additionally, it could enable large-scale space-based solar power collection and transmission back to Earth.
The ring is constructed in sections, each section being lifted by a series of climbers that ascend and descend along the cables. Once in place, the ring would facilitate the transfer of materials between Earth's surface and space, enabling activities such as resource extraction and solar power generation.
Manufacturing the orbital ring involves creating ultra-strong materials capable of withstanding the stresses of being in space while anchored on Earth. The cables would need to be incredibly long and lightweight, making this a significant technological challenge.
The construction process is complex and would likely involve multiple phases. Initial steps include developing and testing the necessary materials, followed by the gradual deployment of segments of the ring from both ends towards the center until they meet in space.
Field units draw low hundreds of watts; fabrication is energy-intensive due to vacuum baking. Assembly processes require significant power input but are offset by the reduced energy needed for satellite launches once the ring is operational.
