Summary
The article discusses the loss of signal from China's Tianwen-1 Mars mission, which AMSAT-DL (German amateur radio satellite organization) has been unable to detect since December 23, 2025, using their 20-meter antenna in Bochum. AMSAT-DL had been receiving and decoding telemetry from the spacecraft almost daily since the mission's launch in July 2020. The lack of signal has been publicly observable through AMSAT-DL's 24/7 livestream, but there has been no official communication from the Chinese space program about the spacecraft's status, leaving its fate unknown.

· 4 pulledAMSAT-DL published the news that they have been unable to receive any signals from Tianwen-1 with the 20 m antenna in Bochum since 2025-12-23.
AMSAT-DL has been using this antenna to receive and decode telemetry from Tianwen-1 almost every day since the beginning of the mission in 2020-07-23.
The news about the lack of signal detected from Tianwen-1 over the last few months were hardly a secret, because AMSAT-DL runs a livestream of the signals received with the Bochum antenna 24/7.
There has been no public communication from the Chinese space program regarding this, so the fate of Tianwen-1 is currently unknown.
