Why send a message into space?

Some things are too big to keep inside. Too important to only exist as a thought. SpaceTransmitter gives those words a physical form — a real radio signal, encoded and transmitted beyond Earth at the speed of light. Not a simulation. Not a gimmick. A real transmission, with a real certificate to prove it happened.

For one dollar, your message becomes part of something permanent. A signal that will travel through space long after the moment that inspired it has passed.

"This message was encoded and transmitted as a real radio signal that has left Earth and continues traveling through space."

This is not a metaphor

Your message is encoded using LoRa chirp spread spectrum modulation and transmitted at 915 MHz with 30 dBm EIRP (1 watt effective radiated power). The signal passes through the atmosphere and continues into space at 299,792 km/s — the speed of light. It does not stop. It does not decay into nothing. It travels outward, forever.

After transmission, you receive a verified PDF certificate documenting exactly what was sent: your message, the timestamp, the frequency, the modulation type, and your unique transmission ID. Frame it, share it, keep it.

Accessible to everyone

A grieving parent. A kid with a dream. A veteran with something to say. For one dollar, anyone can do something extraordinary — send their words beyond the sky and hold the proof in their hands.

Your words are already traveling through space. The only question is whether you've sent them yet.
