🚀 INETS — Interplanetary Nuclear Electric Transport System

“We don’t need faster rockets. We need space infrastructure.”

INETS (Interplanetary Nuclear Electric Transport System) is a next-generation deep space logistics architecture designed to enable sustainable, cost-effective cargo transport between Earth and Mars.

This project was developed as an ideathon-winning concept focused on solving one of space exploration’s biggest bottlenecks: efficient interplanetary cargo transport.

🌌 Problem

Current space missions rely heavily on chemical rockets:

• Extremely fuel inefficient for heavy payloads
• Expensive ($150M+ per Mars mission fuel)
• One-way mission architectures
• Not scalable for colonization

This creates a logistics bottleneck for long-term human presence beyond Earth.

💡 Solution: INETS

INETS introduces a modular, reusable nuclear-electric space tug system.

Core Idea:

• Separate “Lift” (Earth → Orbit) from “Haul” (Deep Space Transport)
• Use nuclear energy + plasma propulsion for high-efficiency travel

---

⚙️ Key Features

🔋 5 MW Nuclear Reactor

• Compact fission reactor (Uranium Nitride fuel)
• Provides continuous high-density power
• Activated only in safe orbit (>800 km)

🔥 VASIMR Propulsion System

• 4 × VX-1250 engines
• Electrodeless plasma propulsion (100,000+ hour lifespan)
• Variable efficiency:
  • High thrust mode → escape gravity
  • High efficiency mode → deep space cruise

📦 Modular Cargo System

• 6 × ISO-Space containers
• Total payload capacity: 150 metric tons
• Standardized, scalable architecture

🔁 Fully Reusable Tug

• Carries 160T propellant
• Capable of Earth → Mars → Earth round trip
• Eliminates need for Mars refueling infrastructure

🚀 Concept of Operations (CONOPS)

1. Lift Phase

   • Chemical rockets deliver cargo to Low Earth Orbit (LEO)

2. Docking

   • Containers attach to INETS Tug

3. Spiral Escape

   • Continuous low-thrust trajectory (30–40 days)

4. Interplanetary Cruise

   • High-efficiency mode (Isp > 10,000 s)

5. Mars Arrival

   • Cargo released for descent

6. Return Mission

   • Tug returns to Earth using onboard fuel
