Thailand’s KNACKSAT-2 satellite is preparing for launch from the International Space Station. Deployment time: February 3, 2026 at 8:55 UTC. Deployment Live Stream: https://www.youtube.com/watch?v=aB4PIOS-hSs January 27, 2026.

The Thailand satellite project KNACKSAT-2 is entering a crucial phase after the satellite was successfully placed on the International Space Station in late 2025. The launch date has been confirmed for February 3, 2026 at 8:55 UTC. After deployment successful. please help to receive telemetry on downlink frequency 400.630 MHz (Not Amateur Radio Band) decode and send report.

This mission marks a significant milestone for King Mongkut’s University of Technology North Bangkok (KMUTNB), building upon the success of Thailand’s first KNACKSAT-1 satellite which was entirely designed and built by a domestic educational institution. Launched into space by a Falcon 9 rocket in 2018 this project was carried out in close cooperation with NBSPACE and a network of domestic and international partners.
