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.
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.

Famous quotes containing the words cosmic and/or call:
“Research is formalized curiosity. It is poking and prying with a purpose. It is a seeking that he who wishes may know the cosmic secrets of the world and that they dwell therein.”
—Zora Neale Hurston (1891–1960)
“With the holders holding my hand nearing the call of the bird,
Comrades mine and I in the midst, and their memory ever to keep, for the dead I loved so well,
For the sweetest, wisest soul of all my days and
lands—and this for his dear sake,
Lilac and star and bird twined with the chant of my soul,
There in the fragrant pines and the cedars dusk and dim.”
—Walt Whitman (1819–1892)
