Answer: Japan
Notes: SLIM (Smart Lander for Investigating the Moon) is a tiny Japanese probe, slightly larger than a tennis ball, sent by the Japan Aerospace Exploration Agency (JAXA) to demonstrate precise landing on the lunar surface. SLIM recently entered the moon's orbit, ahead of a planned touchdown on January 20. If successful, it will showcase Japan's prowess in precision lunar landing with an error margin under 100 metres. This will be a historic achievement making Japan the fifth nation after the US, Russia, China and India to softly land a probe on the moon.
