Start advanced manufacturing Orbital vehicles He teamed up with Virtus Solis Technologies To conduct a solar power demonstration in space by 2027.
The companies say the mission will be a precursor to installing “megawatt-level” solar power in space by 2030, which could represent “a new chapter in renewable energy.”
Space based solar power (SBSP) is not a new idea; The Sun emits more energy than humans can use at the point it reaches Earth, and much of this energy is reflected back into space. Unlike solar energy collected on the planet’s surface, which is subject to a day-night cycle and other restrictions, such as land use, SBSP proponents say it can provide continuous, abundant energy collection.
According to a press release from both companies, it appears they have their work cut out for them. Solar panels used in space are expensive, and a space power station must eventually collect and transmit enough energy to make it economically viable. The plan will not only outline solar energy transmission, but will also include Orbital Robotic assembly capabilities in spacewhich comes with their own set of challenges.
But the vision is compelling, and it opens up a new source of abundant clean energy for Earth. Under the pilot project, Virtus will deploy its 1.65-metre-tall solar tiles into medium Earth orbit, which will then be robotically assembled into large arrays. The two companies are targeting a highly elliptical orbit called a Molniya orbit, which would keep at least one satellite in view of the ground station at all times.
After collecting solar energy, the spacecraft covers it with microwave waves, which will be transmitted to Earth. Once it reaches the ground, it will be converted into electricity and available for transmission to the power grid or used directly.
“This collaboration is not just a milestone in the development of renewable energy;
“Commitment to leveraging space technology for a sustainable future for Earth,” the companies said in a press release. “The success of the pilot plant will validate the practical application of SBSP as a reliable and durable source of energy.”
