Think of it less like a VPN and more like the Pony Express meets BitTorrent.
When your spaceship wants to send a message back to Earth, it doesn't try to establish a connection. It shoves the data to a local proxy node (say, a satellite in high orbit). The proxy says, "I have custody of this bundle." The spaceship can then go back to whatever it was doing (like not exploding).
This proxy node holds onto that data indefinitely. It waits for a "contact opportunity"—a window of time when the antenna is pointing at the receiver. Instead of sending packets, it bundles everything (sensor data, logs, family emails) into a single massive "bundle." interstellar network proxy
It’s latency-tolerant networking. It’s slow. It’s clunky. But it is the only way the human race will ever truly become a multiplanetary species.
On Earth, if a packet drops, you resend it immediately. In space, you wouldn't know a packet dropped for 8 hours. By then, the ship is millions of miles away. The proxy uses forward error correction —sending extra mathematical "hints" so the receiver can rebuild lost data without asking for a resend. Think of it less like a VPN and
In the test, astronauts on the ISS used BP to transfer data to a ground station in Germany. The software waited until the station was overhead, fired the data, and moved on. It worked flawlessly.
We take the internet for granted. When you click a link in New York, a server in Tokyo sends data back in under 200 milliseconds. That "slow" connection feels like the Dark Ages. The proxy says, "I have custody of this bundle
Suddenly, your TCP handshake isn't measured in milliseconds. It’s measured in years .
