Everything you can do with SpaceSIO

Your words, photos, and audio are converted into a genuine radio signal issued from our ground station and sent outward from Earth. This is not a simulation. The transmitting station signs a confirmation the packet went out, and that confirmation is your proof.

Your signal is not sent just once. After the first broadcast we re-transmit it as a daily echo for several days, so the same message goes over the air pass after pass. More passes mean more chances that something out there is listening when it arrives, and each broadcast is logged with its own time, station, and location. Higher plans echo for more days.

Every signal gets a public proof page, and paid plans add a downloadable Certificate of Issuance stamped with the exact date, time, frequency, a SHA-256 payload hash, a QR code to the record, and the packet's own byte-map. Proof it was sent that nothing on Earth can alter.

Each transmission comes with a truthful view of the exact bytes that went over the air: a labeled packet anatomy, a byte-map, a faithful sonification you can play and download, and a 3D sky showing where the Sun, Moon, and planets stood above the station at the moment of launch.

On paid plans a real thumbnail of your photo, or a poster frame of your video, rides over the air as genuine image data, while the full-resolution file is archived on your page. Broadcast and Interstellar add video.

Paid plans include a Model Context Protocol endpoint, so AI agents can issue signals on your behalf, programmatically, with the same proof and telemetry as the web app.

Every signal has its own page with a rich share preview, likes, and real-time comments. A reply can itself be transmitted as its own signal, so a conversation becomes a chain of real broadcasts.

Schedule a signal for a future date and notify a friend or loved one by email the moment it launches. Seal it as a time capsule and the contents stay hidden, even in the feed, until it goes on air. Perfect for birthdays, anniversaries, and messages to the future.
