SAKHACUBE-CHOLBON (Russian: МКА «Чолбон») is the first satellite of the Sakha Republic, a 1U CubeSat built with SPUTNIX Orbicraft-Pro bus. Its payload includes a cluster of 12 Arduino-compatible microcontrollers, a scintillation gamma spectrometer, a camera, and a set of sun sensors for an experimental coarse attitude determination algorithm. School students of the Republic will be uploading firmware to the payload microcontrollers to conduct their own experiments. The spacecraft was launched on December 28, 2025 as a rideshare payload alongside Aist-2T №1, №2 and 49 other satellites. It is jointly operated by Sakha Science Academy and Sakha Aerospace Systems, LLC (YKSA, LLC).
Telemetry and images from the onboard camera, SSTV postcards, audio messages, and other data will be transmitted.
