- The Aist‑2T satellites are designed for stereoscopic Earth imaging to build digital terrain models and support disaster monitoring, with a planned active life of at least five years.
- About 50 secondary payloads are slated for orbit, including university-built CubeSats under the Universat program and the experimental Marathon IoT demonstrator.
- Student satellites will observe climate change and monitor space weather in low Earth orbit for Roshydromet, and the flight is billed as Russia’s final launch of 2025.
