The TAM was created by Russian teens in Moscow Center of Teen Activity and was transmitted at 18:00 UT on
August 29, 2001 from the 70-m dish of Evpatoria Deep Space
Center to the Sun-like star HD 197076 in the Dolphin
Constellation. The total duration of the transmission was 2 hours
12 minutes.
Sounding Section -- coherent signal with slow Doppler wavelength tuning to imitate the transmission from Sun's center (10 min)
Analog Section -- Theremin concert to Aliens (15 min)
Digital Section -- Message: Logo of TAM, Greeting to Aliens both in Russian and English, Image Glossary (70 min).
The Coherent Sounding Signal was transmitted in order to
help Aliens detect the message and to investigate some
radio propagation effects in the interstellar medium.
The Analog Information represents music, performed on
the
Theremin.
This musical instrument produces quasi
sinusoidal signal, which is easily detectable across interstellar distances
(see the Arecibo Proposal submitted on 4 July 2000
for details).
There were 7 musical compositions in the 1st Theremin
Concert for Aliens:
Melody of Russian romance "Egress alone I to the ride"
View SONOGRAMS of the Theremin music.
The Concert program was composed by Russian teens.
The Theremin performers were Lidia Kavina, Yana Aksenova and Anton Kerchenko from the Moscow Theremin Center.
The Digital Information includes the Logo of TAM, Greetings from teens to
Aliens, written both in Russian and English, and an Image
Glossary. The total size of the digital information is
648,220 bits and was transmitted at a
rate 100 bits per second. This section was composed by teens from
different sites of Russia - Moscow. Kaluga,
Zelenogorsk, Voronezh. The 28 images follow in the menu to the left.
