On January 19, 2024, the Japan Aerospace Exploration Agency (JAXA) successfully landed their Smart Lander for Investigating Moon (SLIM). The moment of touchdown was accompanied by the release of two small lunar surface probes, LEV-1 and LEV-2. LEV-2 collects data while moving on the lunar surface, which is then transmitted to LEV-1. What’s interesting is that LEV-1, with its amateur radio license JS1YMG, has been transmitting Morse code using a 1 W UHF antenna. This has sparked the curiosity of radio amateurs, who have been analyzing the signal to demodulate the Morse code and extract the code string. The duration of these signals is uncertain, as SLIM was not built to withstand the lunar night. It is expected to return in a few days. Nonetheless, the landing itself was a remarkable achievement for Japan, making it the fifth country to achieve a soft touchdown on the moon. The precision of the landing was also noteworthy, with the SLIM landing within 180 feet of its intended location.
