Sina-1 (Persian: سینا ۱) is the first Iranian artificial satellite, launched at 6:52 UTC October 28, 2005 on board a Cosmos-3M Russian launch vehicle from the Plesetsk Cosmodrome. The rocket was also carrying a Russian military Mozhayets-5 satellite, a Chinese China-DMC, a British TopSat, a European Space Agency SSETI Express (Student Space Exploration and Technology Initiative-Express), a Norwegian nCube, a German UWE-1, and a Japanese XI-V. Sina-1's Satellite Catalog Number or USSPACECOM object number is 28893.
In 2003, then-Defense Minister Admiral Ali Shamkhani announced that Iran would launch its first satellite on a locally produced launch vehicle within eighteen months. The plan was to develop a booster based on the Shahab-3 medium-range ballistic missile.
When difficulties arose with indigenous booster development, the Iranian Institute of Applied Research turned to the Omsk-based Russian company Polyot. Polyot provided the launch services aboard the Kosmos-3M rocket and also built the satellite itself. The cost of the satellite was US$15 million.
