Nuking Phones from Space: Is it Possible?

TL;DR

No, reliably nuking mobile phones from orbit isn’t currently possible or practical. The energy requirements are immense, the targeting is incredibly difficult, and the collateral damage would be unacceptable. While theoretically conceivable with future technology, it remains firmly in the realm of science fiction.

Why It Won’t Work: A Step-by-Step Breakdown

1. Energy Requirements: Mobile phones are small targets requiring a concentrated burst of energy to destroy. Even a relatively low-yield nuclear weapon would release far more energy than needed, causing widespread damage.
   • A typical mobile phone contains only a few watts worth of components.
   • Even a 1 kiloton yield nuke releases the equivalent of 4.184 x 10¹² Joules – vastly more energy than needed to vaporise a single phone.
2. Atmospheric Effects: The Earth’s atmosphere significantly attenuates and scatters radiation, especially at lower altitudes.
   • A nuclear detonation in space would produce electromagnetic pulse (EMP) and X-rays.
   • The EMP is less effective the further you are from ground zero, and atmospheric absorption weakens it considerably before reaching phones on the surface.
   • X-rays are also absorbed by the atmosphere, reducing their effectiveness.
3. Targeting Challenges: Accurately targeting individual mobile phones from orbit is extremely difficult.
   • Mobile phones are small and constantly moving.
   • Precise orbital mechanics and tracking are required, accounting for the Earth’s rotation, atmospheric drag, and phone movement.
   • Even with advanced sensors, pinpoint accuracy over a large area is unlikely. Consider that GPS has an inherent error margin of several meters.
4. Weapon Delivery: Deploying a nuclear weapon into orbit presents significant logistical and political hurdles.
   • The Outer Space Treaty prohibits the placement of weapons of mass destruction in space.
   • Launching and maintaining a dedicated satellite system for this purpose would be incredibly expensive and visible.
5. Collateral Damage: Even if targeting were precise, there’s a high risk of unintended consequences.
   • EMP effects could disrupt critical infrastructure like power grids, communication networks, and satellites.
   • Radiation fallout, while limited from a space-based detonation, is still a concern.
   • The economic and social impact would be devastating.

What About Focused EMP Weapons?

While nukes are impractical, focused non-nuclear electromagnetic pulse (EMP) weapons have been explored.

1. Vircator Technology: These devices generate short bursts of high-power microwaves.
   • They’re designed to disrupt electronic systems without the widespread damage of a nuclear EMP.
   • However, they still require close proximity to the target and have limited range and effectiveness.
2. Challenges Remain: Even with focused EMP weapons:
   • Power requirements are substantial.
   • Targeting remains a significant issue.
   • Shielding technology is improving, making devices more resistant to EMP effects.

Code Example: Simple GPS Coordinate Calculation (Illustrative)

This demonstrates the complexity of tracking even with known signals like GPS. This isn’t a full solution but shows basic calculations.

import math

def calculate_distance(lat1, lon1, lat2, lon2):
  # Convert latitude and longitude from degrees to radians
  lat1 = math.radians(lat1)
  lon1 = math.radians(lon1)
  lat2 = math.radians(lat2)
  lon2 = math.radians(lon2)

  # Haversine formula
  dlon = lon2 - lon1
  dlat = lat2 - lat1
  a = math.sin(dlat / 2)**2 + math.cos(lat1) * math.cos(lat2) * math.sin(dlon / 2)**2
  c = 2 * math.atan2(math.sqrt(a), math.sqrt(1 - a))
  radius = 6371 # Radius of earth in kilometers
  distance = radius * c
  return distance

# Example coordinates (London and New York)
lat1, lon1 = 51.5074, 0.1278
lat2, lon2 = 40.7128, -74.0060

distance = calculate_distance(lat1, lon1, lat2, lon2)
print(f"Distance between London and New York: {distance} km")

This simple example highlights the need for complex calculations to determine a phone’s position accurately. Real-world tracking involves many more variables.
