Cosmic Call

Cosmic Call was the name of two interstellar radio messages that were sent from RT-70 in Yevpatoria in 1999 and 2003 to various nearby stars. The messages were designed with noise-resistant format and characters.

The project was funded by Team Encounter, a Texas-based startup that went out of business in 2004.^[1]

Each Cosmic Call 1 session had the following structure. Scientific Part (DDM, BM, AM, and ESM) was sent three times, and Public Part (PP) was sent once, according to the following arrangement:

DDM BM AM ESM DDM BM AM ESM DDM BM AM ESM PP,

where DDM is Dutil-Dumas Message, created by Canadian scientists Yvan Dutil and Stephane Dumas, BM is Braastad Message, AM is Arecibo Message, ESM is Encounter 2001 Staff Message; more details present at Report on Cosmic Call.

Each Cosmic Call 2 session had the following structure:

DDM2 DDM2 DDM2 AM AM AM BIG BIG BIG BM ESM PP,

where DDM2 is modernized DDM, BIG is Bilingual Image Glossary; more details present at Synthesis and Transmission of Cosmic Call 2003 Interstellar Radio Message.

The messages were sent to the following stars:^[2]
