Summary
On August 2, 2026, Peter Gülzow observed that the Tianwen-1 spacecraft was transmitting telemetry at a significantly lower rate than usual. This low rate suggests that the spacecraft is in a safe mode configuration, ideal for low gain antenna scenarios. Gülzow recorded several short IQ recordings of the transmission.
