Because the best stargazing requires seclusion, astrotourism is a boon to remote areas that do not usually lure tourists. DarkSky International, a non-profit, certifies resorts and reserves with the best night-time conditions. It has seen a substantial increase in the number of applications in the past three years, growing from 16 in 2023 to 28 applications in the first half of 2026 alone.

Astro Retreat in Maan, an Indian village in the Himalayas, has seen a surge in visitors of late. Al Ula, in the Saudi Arabian desert, is going big on astrotourism by building a state-of-the-art observatory and luxury stargazing lodges. John Barentine, an astronomer in Arizona, says there is an opportunity for rural places where industries such as mining have waned.

​What alarms researchers most is the sheer scale. More than 15,000 satellites, active and inactive, are already circling Earth, and the proposed additions would mean thousands of launches and re-entries every year.

That concern has already been raised with regulators. In comments submitted to the FCC, the Center for Space Environmentalism called the proposals "a massive industrialization of orbit that poses severe collision risks."

Astronomer John Barentine warned, "We are teetering on the precipice of how the uses of space are changing, and that threatens our ability to use space."

​Researchers and space governance experts say current agreements like the Outer Space Treaty don’t adequately address stewardship, equity and collective responsibility, required ingredients for a framework that can effectively manage space for the common good.

“We are teetering on the precipice of how the uses of space are changing, and that threatens our ability to use space,” said astronomer and dark sky policy expert John Barentine, who co-founded the Center for Space Environmentalism in 2025.

The center filed formal comments with the FCC on all four satellite-fleet proposals, writing that the deployments are “a massive industrialization of orbit that poses severe collision risks” and that they push the massive energy demands of artificial intelligence into low Earth orbit, threatening its sustainability. And mirroring sunlight to Earth from satellites could threaten ecosystems and disrupt astronomical research, the group added.

The foundation of global space law that has governed human activity outside Earth for nearly six decades may be approaching a breaking point, according to a new analysis by two astronomers who argue that the legal framework created during the Cold War is inadequate for an era of commercial spaceflight, global political instability, and growing militarization of orbit.

The study, published in Frontiers in Space Technologies, argues that the 1967 Outer Space Treaty (OST), long regarded as the foundation of peaceful space exploration, confronts mounting challenges from transforming global power shifts, increasing orbital competition, and the emergence of private companies as dominant players in space activities.

​Dr. John Barentine of the Center for Space Environmentalism and Dark Sky Consulting, along with Dr. Aparna Venkatesan, a physicist and astronomer at the University of San Francisco, contend that while the treaty remains valuable, it may not be able to address the realities of the modern space age.

​Oh, like what if a satellite breaks into pieces and they hit other satellites, leading to a cascade of destruction that breaks everything in orbit and leaves the globe perpetually surrounded by flying space trash that cannot be bypassed, with no proven way to remove it? Yes, maybe. It's called the Kessler syndrome, and astronomers have been worried about it happening for decades. It's always been a theory. But now the world is in an era where companies are trying to pump thousands—even a million—satellites into orbit

“That is literally the thing that keeps me awake at night,” says John Barentine, an astronomer and founder of Dark Sky Consulting in Tucson, Arizona. “The sense that we are teetering on the edge of catastrophe, and most people don't understand that.”

John Barentine (Dark Sky Consulting), who was not involved in the Nature study, emphasizes that despite patches of dimming lights, the world is brightening on large spatial scales. That has implications for those interested in protecting dark, starry skies.

“Since artificial light at night is a pollutant that effortlessly crosses jurisdictional boundaries,” Barentine says, “village-by-village light pollution abatement plans are very limited in what they can achieve beyond hyperlocal effects.”

“[A] key take-away is that in order to be successful in reducing light pollution, we have to organize on larger spatial scales,” he adds, offering the EU Nature Restoration Regulation as a point of reference. “An increasingly top-down approach is called for.”

Another natural resource that will undoubtedly be affected by orbital data centers is the night sky. These satellites, necessitating large solar arrays, will be much more visible than most satellites today. And if companies like SpaceX have their way, there would be something like a factor of 100 more satellites than what are zipping around orbit today. It is a sobering thought for astronomers, who not only love a dark sky but also rely on it to make observations.

The astronomical community has dealt with satellites photo-bombing the night sky for a long time, but the problem worsened in 2019 when SpaceX started launching operational Starlink satellites. So far, scientists and the space companies have largely been able to work out their differences.

“At this point in time, largely because we have pursued dialogue with the industry, we have avoided what we were concerned about in 2019 as the worst outcome,” said John Barentine, an astronomer and self-described “defender” of dark skies. “We’ve seen companies like SpaceX, and some of their competitors, making efforts on a voluntary basis to reduce their impact on ground-based astronomy.”

​As Space.com reports, the plans were met with alarm by astronomers, who have spent years collaborating with SpaceX to stop Starlink satellites from ruining their work.

“It really feels like it’s undermining what we have achieved in the last few years, which wasn’t ideal for astronomy, but was a far cry from what we feared in 2019 when the Starlink program began,” astronomer and dark sky consultant John Barentine told Space.com.

Barentine, alongside a consortium of astronomers, filed a challenge to SpaceX’s FCC filing.

“We felt we were heading in the right direction that was reasonably sustainable,” he added. “And this feels like a complete reversal of that.”

Manipulating sunlight has raised concerns among experts about the effect of light pollution on the environment and biodiversity.

​“The beam reflected by these satellites is very intense, four times brighter than the full moon, and they will be flying multiple satellites in a formation,” John Barentine, an astronomer at the Silverado Hills Observatory and consultant at Dark Sky Consulting, told Space.com (a sister site of The Week). The brightness will “have an effect on wildlife in the directly illuminated area but also, through atmospheric scattering, on the surrounding areas.”
