IN BRIEF
  • 🚀 Aetherflux raises $50 million to launch an orbital demonstrator by 2026.
  • 🔆 Modular satellites collect solar energy and transmit it to Earth via infrared lasers.
  • 🌍 The startup challenges international competition with financial backing from the U.S. Department of Defense.
  • 🔧 Modular technology allows for gradual improvement and adaptation to energy needs.

Aetherflux, a promising startup based in the United States, has recently captured global attention with its ambitious project of modular solar satellites. With $50 million in funding, the company aims to revolutionize how solar energy is collected and transmitted to Earth. Founded by Baiju Bhatt, whose background spans physics and finance, Aetherflux stands out for its innovative vision and rapid technological advancements. Next year, it plans to launch an orbital demonstrator, marking a significant milestone in the utilization of space solar energy.

The Solar Space Technology of Aetherflux

On April 2, Aetherflux announced it had raised $50 million in a Series A funding round. This financing, backed by Breakthrough Energy Ventures and NEA, highlights the growing interest in space energy technologies. CEO Baiju Bhatt founded the company with a clear vision inspired by his father, a former NASA scientist. The satellites from Aetherflux are designed to collect solar energy and transmit it to Earth using lasers. Unlike traditional proposals that rely on large arrays in geostationary orbit, this modular approach allows for gradual enhancement and scalability. Bhatt critiques conventional concepts he sees as too rigid, proposing a more flexible alternative that could transform the energy sector.

Aetherflux: An Orbital Demonstrator by 2026

In 2026, Aetherflux plans to test its technology in space with the support of Apex, which will provide the space bus. This mission, aboard a SpaceX Transporter mission, will be a pivotal moment for the startup. Once in orbit, Aetherflux’s demonstrator will transmit energy to Earth using an infrared laser with a diameter of 10 meters. Unlike large arrays in geostationary orbit that constantly receive sunlight, Aetherflux’s satellites operating in low orbit will need to manage energy storage to function efficiently at night. This technical challenge also presents an opportunity for innovation, as Aetherflux promises to enhance its capabilities over time.

An ‘Urgent’ Goal for Aetherflux

Aetherflux is distinguished by its ambition and speed of execution. With the new funding, the company aims to accelerate its projects and establish itself in a new race for space energy. International competition is fierce, as China and the European Space Agency are also advancing similar projects. Aetherflux has secured financial support from the U.S. Department of Defense to develop a concept for energy transmission from low orbit. The challenge is significant, but it is crucial for the United States to remain at the forefront of this technology, to avoid losing energy leadership to other nations.

Challenges and Opportunities for the Future

Aetherflux’s mission goes beyond merely demonstrating technology; it aims to redefine access to renewable energy. Modular satellites offer unparalleled flexibility, enabling rapid adaptations to technological advancements and energy needs. The success of this endeavor could catalyze new innovations in the energy sector, paving the way for more efficient and sustainable use of space resources. However, numerous challenges remain, particularly regarding regulation, space debris management, and long-term economic viability. How will these obstacles be overcome, and what new solutions will emerge to shape our energy future?
