Introduction: The 20-Minute Lag
If you're on Mars and you want to load a webpage from Earth, the signal has to travel 140 million miles. At the speed of light, this takes about 20 minutes. Standard IP protocols (like TCP) will 'Time Out' and fail immediately. To get a Mars IP Address to work, we need a whole new system called **DTN (Delay-Tolerant Networking)**.
Store and Forward
DTN works like an 'Old School' post office. Instead of waiting for a 'Handshake', every router (like a satellite around Mars) **Saves** a copy of your packet until it sees a clear path to the next hop. It doesn't matter if the connection is 'Broken' for ten minutes; the IP packet will just wait until it’s safe to move again.
Conclusion
Networking on Mars isn't just about 'New Numbers'—it’s about a new way of thinking about time and distance. See the Mars link status here.
