Currently it forms part of Kazakhstan's National Center for Space Research and Technologies.

After the fall of the Soviet Union in 1991, none of the observatory's 1-meter telescopes were in working order on account of outdated equipment and lack of spare parts.

In collaboration with the South Korean Institute for Astronomy and Space Sciences, the Tien Shan Observatory is planning to install an automated telescope of 50 cm in diameter.
