La prima è quasi sicuramente una boutade, per semplici problemi di geometria.
Sulla seconda non saprei per mia scarsa conoscenza tecnica sui DTC, ma so che sono estremamente energivori, sicuri che bastano dei semplici pannelli solari per alimentare il sistema di calcolo e di trasmissione/ricezione?
Insomma, tutta sta roba mi sa tanto di boutade-simil-hyperloop. :mrgreen:

Io comunque ho fatto i miei commenti per entrambe.

Ecco 4 diversi spunti per spaceX (hehe usa l'AI concorrente):


1) Orbital congestion.


Dear Commissioners,

I am writing to express concern regarding SpaceX’s proposal to dramatically expand the number of satellites in low Earth orbit. Increasing the active satellite population by roughly seventy times would significantly heighten the risk of collisions and cascading debris events.

Low Earth orbit is already congested. A massive increase in objects — particularly large, operational platforms — raises the probability of accidental collisions, system failures, and long-term debris generation that could jeopardize access to space for all nations and future generations.

Given the irreversible consequences of a debris cascade, I respectfully urge the Commission to require rigorous independent modeling and a comprehensive environmental review before approving any such expansion.

Sincerely,
[Your Name]
[Your City and State]

2) Atmospheric Impact

Dear Commissioners,

I am writing to raise concerns about the atmospheric impacts of SpaceX’s proposed large-scale satellite deployment. The increased launch frequency and eventual re-entry of vast numbers of satellites would introduce substantial quantities of emissions and metallic particulates into the upper atmosphere.

The long-term effects of these pollutants — including potential impacts on atmospheric chemistry and climate — remain insufficiently understood. Approving expansion at this scale without comprehensive lifecycle analysis risks creating environmental consequences that are global and irreversible.

I urge the Commission to require a full Environmental Impact Statement and independent atmospheric studies prior to considering approval.

Sincerely,
[Your Name]
[Your City and State]

3) Loss of the Night5 Sly

Dear Commissioners,

I am writing to express concern about the impact of large-scale satellite deployment on the visibility of the night sky. Sunlight scattered from satellite surfaces contributes to increasing skyglow, diminishing humanity’s ability to see the stars.

Beyond aesthetics, this affects professional and amateur astronomy, near-Earth object detection, and our shared cultural and scientific heritage. The night sky is a universal human resource that should not be degraded by commercial expansion without careful review and mitigation.

I respectfully request that the Commission consider these impacts fully before approving further large-scale deployments.

Sincerely,
[Your Name]
[Your City and State]

4) Ecosystem disruption

Dear Commissioners,

I am writing to raise ecological concerns related to increased satellite numbers in low Earth orbit. Additional reflected light from satellites contributes to artificial skyglow, further disrupting natural cycles of light and darkness.

Many species rely on consistent night conditions for migration, reproduction, navigation, and predator-prey balance. Expanding orbital infrastructure at unprecedented scale risks compounding existing light pollution and placing further stress on already vulnerable ecosystems.

I urge the Commission to carefully assess these ecological consequences through comprehensive environmental review before granting approval.

Sincerely,
[Your Name]
[Your City and State]

5) Space as a Global Common

Dear Commissioners,

I am writing to express concern regarding the broader governance implications of large-scale satellite deployment in low Earth orbit. Outer space is recognized under international law, including the Outer Space Treaty, as a global commons to be used for the benefit of all humankind.

Allowing a single private corporation to occupy and operationally dominate vast portions of orbital space raises serious questions about equitable access, long-term stewardship, and the rights of other nations and future generations. Decisions that effectively allocate shared orbital resources for private commercial use carry multinational consequences and should not be made without robust international coordination and careful consideration of global interests.

Low Earth orbit is not the property of any one company or country. It is a shared environment whose sustainability and accessibility must be protected.

I respectfully urge the Commission to consider the international and intergenerational implications of this proposal before granting approval.

Sincerely,
[Your Name]
[Your City and State]

Se qualcuno ne fa anche solo qualcuna.. (La 5 mi pare un argomento forte perchè indica già potenziali violazioni di trattati e conseguenze legali).

Reflected Orbital

1) environmental consequences


Dear Commissioners,

I am writing to express concern about the environmental consequences of increased reflected light from large satellite constellations in low Earth orbit. Sunlight scattered from satellite surfaces contributes to artificial skyglow, extending human light pollution into regions far beyond urban centers.

Many species rely on natural cycles of light and darkness to regulate migration, reproduction, feeding, and predator avoidance. Even subtle increases in nighttime brightness can disrupt insect populations, bird navigation, marine life behavior, and plant physiology. Expanding orbital infrastructure at unprecedented scale risks compounding existing light pollution and placing additional stress on already vulnerable ecosystems.

Given the cumulative and far-reaching nature of these impacts, I urge the Commission to require comprehensive environmental review before approving further large-scale deployments.

Sincerely,
[Your Name]
[Your City and State]

2) Human Wellbeing and Public Safety


Dear Commissioners,

I am writing to raise concerns about the human health and safety implications of increased reflected light from large satellite deployments. Additional skyglow contributes to the erosion of natural nighttime darkness, which plays a critical role in regulating human circadian rhythms and sleep cycles.

Artificial light at night has been associated with sleep disruption and broader health effects. Beyond physiological concerns, bright moving satellites and reflected glare may create distractions or hazards for drivers, pilots, and individuals using optical instruments. Increased glare in dark-adapted environments can compromise visual performance and situational awareness.

Before approving expansion at significant scale, I respectfully urge the Commission to evaluate the cumulative impacts of orbital light on public health and safety.

Sincerely,
[Your Name]
[Your City and State]

3) Astronomy

Dear Commissioners,

I am writing to express serious concern regarding the impact of reflected orbital light on astronomical research. Large numbers of reflective satellites increase overall sky brightness and produce streaks across telescope images, degrading data quality and reducing the sensitivity of ground-based observations.

Modern astronomical instruments are designed to detect extremely faint signals from distant galaxies, exoplanets, and near-Earth objects. Increased skyglow and satellite interference threaten long-exposure imaging, time-domain surveys, and radio astronomy. This affects not only scientific discovery but also planetary defense efforts that rely on detecting potentially hazardous asteroids.

The night sky is both a scientific resource and a shared human heritage. I urge the Commission to carefully consider these consequences before authorizing large-scale deployment.

Sincerely,
[Your Name]
[Your City and State]

4) Orbital Debris

Dear Commissioners,

I am writing to express concern about increased collision and debris risks associated with large-scale satellite expansion in low Earth orbit. The orbital environment is already crowded, and significantly increasing the number of active satellites raises the probability of accidental collisions.

Each collision event can generate thousands of debris fragments, increasing the risk of further impacts in a cascading effect. Such a scenario could compromise access to space for commercial, scientific, and governmental missions for decades.

Given the shared and finite nature of orbital space, I respectfully urge the Commission to require rigorous independent modeling of collision probabilities and debris mitigation strategies before approving additional large-scale deployments.

Sincerely,
[Your Name]
[Your City and State]

5) economic damages and commercial impacts on dark-sky–dependent industries:

Dear Commissioners,

I am writing to express concern regarding the economic consequences of increased reflected orbital light from large satellite deployments. The progressive brightening of the night sky does not only affect science and ecosystems — it also carries tangible financial costs for industries and communities that depend on natural darkness.

Dark-sky tourism has become an important source of revenue for rural regions, national parks, and designated Dark Sky Reserves. Visitors travel specifically to experience pristine night skies, generating income for local lodging, guiding services, observatories, and hospitality businesses. Increased skyglow from satellite reflections threatens the very resource these communities rely upon.

In addition, commercial activities such as astrophotography, amateur astronomy equipment markets, educational observatories, and stargazing events depend on clear, dark conditions. Diminished sky quality reduces demand, undermines investments, and erodes economic opportunities tied to nighttime experiences.

Before approving large-scale orbital expansion, I respectfully urge the Commission to assess the potential economic harm to dark-sky–dependent industries and communities. The night sky is not only a cultural and scientific asset — it is also an economic resource whose value should not be compromised without careful consideration.

Sincerely,
[Your Name]
[Your City and State]

Se non l'ha detta Einstein, me la attribuisco volentieri io. :ook:
A scanso di equivoci è contro chi ha richiesto di poter mettere in orbita 1 000 000 di satelliti. :ook:

Le citazioni non possono essere infinite perché fatte da un numero finito di persone in un tempo finito (teorema di Einstein-Swarzchild).
