The Dark Side of ‘Sunlight on Demand’: Could Orbital Mirrors Eclipse the Night Sky?

Imagine a future where solar farms operate 24/7, powered not by batteries, but by beams of sunlight reflected from orbiting mirrors. It sounds like science fiction, but US startup Reflect Orbital is aiming to make it a reality. However, this ambitious plan to deliver “sunlight on demand” is sparking serious concern among astronomers – and for good reason. The potential for unprecedented light pollution, and the practical hurdles to achieving this technology, raise questions about whether this innovation is a bright idea, or a dangerous distraction.

How Reflect Orbital Plans to Illuminate the Night

Reflect Orbital’s concept is deceptively simple: deploy a constellation of satellites equipped with massive mirrors to bounce sunlight onto solar farms after sunset. Their initial plan involves launching Earendil-1, an 18-meter test satellite in 2026, followed by a network of approximately 4,000 satellites by 2030. The company envisions these satellites, orbiting around 625km above Earth, using mirrors up to 54 meters across to redirect sunlight. But the physics of beaming light across such vast distances presents significant challenges.

The Problem with Spreading the Light

Unlike a laser, sunlight isn’t a concentrated beam. It’s a diffuse source, spanning half a degree in the sky. This means that even with a large mirror, the reflected light will spread out considerably over distance. Calculations show that a satellite 800km away would illuminate an area at least 7km across. While a single 54-meter satellite would be 15,000 times fainter than the midday sun, it would still be significantly brighter than the full moon. To achieve a usable 200 watts per square meter – roughly 20% of midday sun – Reflect Orbital estimates needing around 3,000 satellites per location. And even then, the illumination window would be brief, as satellites at that altitude move at a staggering 7.5 kilometers per second, offering only a few minutes of direct sunlight to any given area.

Beyond the Technical Hurdles: The Looming Threat of Light Pollution

The technical challenges are substantial, but the potential for light pollution is arguably the more pressing concern. Unlike existing satellites that incidentally reflect sunlight, Reflect Orbital’s satellites are designed to be bright. Even the test satellite, if successful, could appear brighter than the full moon. A constellation of thousands of these mirrors would be devastating to astronomical observation. The surface of each mirror could appear as bright as the sun through a telescope, posing a risk of permanent eye damage to astronomers. Beyond professional observatories, the increased skyglow would hinder amateur astronomy and impact the natural rhythms of wildlife. The company has stated it plans to avoid observatories and share satellite locations, but the sweeping motion of the satellites means light will inevitably spill into sensitive areas.

The Balloon Test: A Limited Preview

Reflect Orbital conducted a balloon test last year, demonstrating that a 2.5-meter mirror could deliver 516 watts per square meter at a distance of 242 meters – comparable to half the intensity of the midday sun. However, scaling this test to the 800km altitude of the proposed satellites reveals a critical limitation. To achieve the same intensity, the reflector would need to be a colossal 6.5km by 6.5km, an impractical size for a space-based system. This highlights the fundamental difficulty of concentrating sunlight over such immense distances.

A Constellation of Concerns: Is 250,000 Satellites Realistic?

Reflect Orbital’s founder, Ben Nowack, has even suggested a future constellation of 250,000 satellites. This dwarfs the number of currently cataloged satellites and space debris. Even with this massive deployment, the company would only be able to illuminate around 80 locations simultaneously, and even that number is optimistic, factoring in potential cloud cover. Furthermore, illumination would be largely limited to dawn and dusk, when the satellites are in sunlight. The sheer scale of this proposed infrastructure raises questions about its feasibility and sustainability.

The Future of Space-Based Solar Power and the Night Sky

While the concept of space-based solar power holds long-term promise, the current approach proposed by Reflect Orbital appears fraught with challenges. The technical hurdles are significant, and the potential for irreversible damage to the night sky is substantial. The debate highlights a critical tension between technological innovation and environmental preservation. As we continue to explore ways to harness the power of space, it’s crucial to prioritize responsible development and consider the broader consequences of our actions. Space-based solar power is a rapidly evolving field, and alternative approaches may offer more sustainable solutions.

The Cybercrime Economy is Maturing: Why ‘Ransomware-as-a-Service’ is Just the Beginning

The recent attack on UK nursery chain Kido, threatening the exposure of children’s personal data, wasn’t just shocking – it was a symptom of a far larger, and increasingly sophisticated, problem. Cybercrime isn’t simply a series of opportunistic hacks anymore; it’s a fully-fledged, multi-billion dollar industry, and it’s evolving at an alarming rate. The shift from isolated attacks to a structured, service-based model is fundamentally changing the threat landscape, and businesses need to understand this new reality to survive.

From Lone Wolves to Organized Crime

For years, cybersecurity focused on battling individual hackers or small, loosely connected groups. Today, that approach is increasingly ineffective. Cybercrime has matured into a complex ecosystem mirroring legitimate businesses, complete with supply chains, affiliates, and even customer support. This transformation is driven by simple economics: where there’s profit, there’s incentive, and the potential rewards in cybercrime are enormous.

The “as-a-service” model is at the heart of this evolution. Just as companies can rent software or security solutions, criminals now offer “Ransomware-as-a-Service” (RaaS), botnets for hire, and even initial access to compromised networks. This lowers the barrier to entry, allowing less skilled individuals to participate in attacks, while experienced hackers focus on development and infrastructure. Think of it as a dark web franchise operation – a chillingly efficient way to scale malicious activity.

The Rise of Specialized Roles: Initial Access Brokers and Beyond

Within this ecosystem, specialized roles are emerging. “Initial Access Brokers” are particularly concerning. These are skilled hackers who gain entry into systems and then sell that access to others, often ransomware operators. This effectively creates a tiered system, where one criminal’s skill set unlocks opportunities for others, amplifying the overall threat. The packages they sell aren’t just data; they include usernames, passwords, and direct network access – a complete key to the kingdom.

The Economic Impact: Beyond Financial Losses

The financial costs of cybercrime are staggering. Attacks on companies like M&S and Co-op, facilitated by services like DragonForce (reportedly charging 20% of ransom payments), caused significant disruption and millions in losses. But the impact extends far beyond immediate financial damage. The Jaguar Land Rover (JLR) attack, which halted production for weeks, created a ripple effect throughout their supply chain, threatening the viability of smaller businesses. This demonstrates how a single cyberattack can destabilize entire industries.

Perhaps more insidious is the erosion of trust. When consumers lose confidence in a company’s ability to protect their data, it damages brand reputation and long-term economic stability. The glamorization of hackers in popular culture often obscures the very real and damaging consequences of their actions.

Why Prevention Alone Isn’t Enough: The Need for Resilience

While preventing attacks remains crucial, it’s no longer sufficient. The reality is that breaches *will* happen. The key to minimizing damage lies in building resilience – the ability to withstand an attack and maintain operations. Companies that prioritize resilience, like Harrods and Co-op in the examples cited, are able to limit disruption, protect data, and reduce financial losses.

Investing in advanced technologies, particularly Artificial Intelligence (AI), is essential. AI can enhance threat detection, automate incident response, and improve overall security posture. However, technology alone isn’t the answer. A robust resilience strategy requires comprehensive planning, regular testing, and a culture of security awareness throughout the organization.

The Role of Legislation and the Future of Cybercrime

The UK government’s Cyber Security and Resilience Bill is a step in the right direction, as are consultations on ransomware payments. However, legislation can only go so far. True change requires a fundamental shift in corporate mindset. Companies must commit to prioritizing cybersecurity, not as a cost center, but as a critical business imperative.

Looking ahead, we can expect the cybercrime economy to become even more sophisticated. We may see the emergence of specialized “cybercrime insurance” offerings, further incentivizing attacks. The use of AI by both attackers and defenders will escalate, leading to a constant arms race. And the targeting of critical infrastructure – energy grids, healthcare systems, and financial institutions – will likely increase, posing a significant threat to national security. Interpol’s Cybercrime Programme provides valuable insights into these evolving threats.

Ultimately, breaking the cycle of cybercrime requires a collective effort. By refusing to pay ransoms, investing in resilience, and fostering a culture of security, businesses can diminish the profitability of this illicit industry and protect themselves, their customers, and the wider economy.
