The OSSI-1 CubeSat lifted off on a Soyuz-2-1a with the research satellite Bion-M1 from Launch Complex 31 at Baikonur in Kazakhstan on Friday, April 19 at 1000 UT and was deployed from the Pod mounted on top of Bion-M1 at 1615 UT.

Korean artist and radio amateur Hojun Song DS1SBO has spent 7 years developing his Open Source Satellite Initiative satellite OSSI-1. He has designed and built it from scratch using readily available components rather than expensive space qualified hardware. The launch was the most expensive part of the project costing $100,000.

OSSI-1 weighs 963 grams

OSSI-1 has a 12 WPM CW Morse code beacon on 145.980 MHz, a data communications transceiver on 437.525 MHz using AX.25 FSK packet radio and carries a 44 watt LED optical beacon to flash Morse code messages to observers on Earth.

The OSSI-1 145.980 MHz Morse Code beacon will send “OS0 DE OSSI1 ANYOUNG”.

OSSI-1 launched on April 19, 2013 on a Soyuz-2-1b rocket from the Baikonur launch facility in Kazakhstan along with the Bion-M1, SOMP, BEESAT 2, BEESAT 3 and Dove-2 satellites.
