Send your message into deep space

Write up to 100 words, choose a star or galaxy, and we encode your message as a binary radio signal at the hydrogen line — the same frequency SETI listens on. Transmission launches about 6 hours after purchase. You get a verified certificate and a live Signal Tracker that follows your words across the cosmos.
