IN A NUTSHELL
  • 🚀 Aetherflux, a US startup, raised $50 million to launch a constellation of modular satellites by 2026.
  • 🔋 The satellites aim to harness solar power in space and beam it to Earth using laser technology.
  • 🌐 The approach is modular, allowing iterative improvements, setting it apart from traditional geostationary models.
  • ⚡ Aetherflux is racing against global competitors, urging the US to prioritize space solar power to maintain energy leadership.

The realm of space-based solar power is taking a bold leap forward with the initiatives spearheaded by Aetherflux, a US startup poised to revolutionize energy transmission from orbit to Earth. With an impressive $50 million in Series A funding secured, Aetherflux is setting the stage for a groundbreaking technology demonstrator scheduled for launch in 2026. This ambitious venture, leveraging a constellation of modular satellites in low Earth orbit, promises to redefine the traditional approaches to harnessing solar power from space. As Aetherflux races against global competitors, the stakes for energy leadership have never been higher.

Aetherflux’s Space Solar Power Technology

Aetherflux has set its sights on transforming the way solar power is harnessed from space. Announced on April 2, the startup secured a substantial $50 million in its Series A funding round, with prominent investors like Breakthrough Energy Ventures and NEA joining the cause. Founded by CEO Baiju Bhatt, who has a rich familial connection to NASA, Aetherflux began as a self-funded venture with Bhatt investing $10 million of his own funds. The company’s vision is to develop a constellation of modular satellites capable of collecting solar power and beaming it to Earth using lasers.

Traditionally, the concept of space-based solar power involved massive arrays positioned in geostationary orbit, transmitting energy via microwave beams to extensive ground stations. However, Aetherflux’s approach is distinctively modular, allowing for incremental improvements and scalable deployments. This stands in stark contrast to the traditional “all or nothing” models, which have hindered the progress of space-based solar power technology. Through its innovative design, Aetherflux aims to overcome these challenges and propel the sector forward.

Aetherflux to Demonstrate Technology in Orbit by 2026

The forthcoming in-orbit demonstration by Aetherflux marks a pivotal step in its quest to validate its technology. The company has already proven its power transmission capabilities in laboratory settings and is now eager to test its systems in the actual space environment. This demonstration will utilize a spacecraft bus supplied by Apex and is set to launch aboard a SpaceX Transporter mission in 2026.

Once deployed in orbit, Aetherflux’s demonstrator will employ an infrared laser to transmit power back to Earth, showcasing a spot size of 10 meters. As the company iterates on its design, it aims to enhance this capacity further. Unlike traditional large arrays in geostationary orbit, which benefit from continuous sunlight, Aetherflux’s low Earth orbit satellites will require efficient power storage solutions to operate during nighttime. This emphasis on storage highlights a crucial aspect of their design, addressing the challenges posed by the orbital environment.

Aetherflux’s ‘Urgent’ Goal

Aetherflux is driven by a sense of urgency to establish itself as a leader in the emerging space solar power race. The company’s latest funding will accelerate its progress, enabling it to compete with global entities like China and the European Space Agency, both of which are advancing their space solar power initiatives. The startup emphasizes the need for the United States to prioritize this technology or risk losing energy leadership.

To bolster its efforts, Aetherflux has secured government support through the Defense Department’s Operational Energy Capability Improvement Fund (OECIF). This backing will aid in developing a proof of concept for power transmission from low Earth orbit. As global competitors intensify their efforts, Aetherflux is committed to moving swiftly and proactively to secure its position in this high-stakes domain.

The Future of Space-Based Solar Power

The potential of space-based solar power is immense, offering a sustainable and continuous energy source that could revolutionize global energy systems. Aetherflux’s innovative approach, characterized by modularity and scalability, presents a viable path forward in overcoming the limitations of traditional models. The company’s progress could pave the way for a new era of energy generation from space, with significant implications for energy security and environmental sustainability.

As Aetherflux prepares to launch its demonstrator and refine its technology, the world watches with anticipation. The success of this venture could signal a transformative shift in how we approach energy production, potentially setting a new standard for the industry. As the race for space solar power intensifies, the question remains: How will Aetherflux’s advancements shape the future of energy on Earth, and will other nations rise to the challenge?

  1. So weird to mention China admits to felling behind in the headline, then never mention anything about it in the article.

    Its almost like this website hates China and is jist writing propaganda headlines.

  2. Brad Naksuthin on

    No where in the article (except for the title) was the claim ever made that

    This is just more sensationalistic Journalism. I pray for the day when human journalists are all replaced by AI
