SECTOR 7G // MISSION BRIEF
THE SECOND WORLD
ENTRY DATE: 1977.09.05 // CLASSIFICATION: OMEGA-7
Signal acquisition confirmed at 1420.405 MHz on the hydrogen line. Automated deep-field survey array HELIOS-II detected anomalous spectral signatures consistent with atmospheric biosynthesis at coordinates RA 14h 29m 43s, Dec -62d 40m 46s. Preliminary analysis indicates a terrestrial-mass body orbiting within the habitable zone of a G-type main sequence star at 4.243 light-years.
The discovery was classified immediately. A monitoring station was established. The transmission protocols were drafted but never authorized for broadcast. This terminal contains the complete mission archive.

OUTGOING TRANSMISSION // DRAFT
TRANSMISSION LOG
This is a message from the third planet of the star you know as your nearest neighbor. We have listened to your signal for forty-six years. We have catalogued your world, measured your atmosphere, calculated the rhythm of your seasons. We have composed this reply nine hundred and twelve times in seventeen languages and found each version insufficient. What we wish to say is simpler than any protocol allows: we heard you. Across four light-years of silence, through the static of galaxies, your signal reached us and we understood that we are not alone. We do not know if you intended to be heard. We do not know if you are still listening. But we are sending this message into the dark because the alternative — knowing you exist and saying nothing — is a silence we cannot|
