Japan Lunar Spacecraft Loops Past Moon on Circuitous Route to Precise Landing

700-kg Smart Lander for Investigating Moon (SLIM) passed within 4,992 km of the lunar surface, imaging Moon from ~7,000-km and is now on long, fuel-saving path to LOI expected to take 2-3 months, followed by a month in lunar orbit with landing within 100-m target zone near Shioli crater / Cyrillus crater rim (13.3°S, 25.2°E) NET Jan 2024; Japan will come 5th nation to soft-land on Moon (after USA, USSR, China, India) if SLIM is successful; Payloads include Multi-Band Camera, Lunar Excursion Vehicle, Laser Retro-reflector

JAXA Counting Down to Launch of Smart Lander for Investigating Moon (SLIM)

SLIM set to lift off on H-2A rocket with XRISM rideshare from Tanegashima Space Center 26 August 09:34 JST (00:34 UTC) for 4–6-month journey to landing site at 13.2°S, 25.2°E, an area east of Shioli, a 270-m diameter crater emanating distinctive bright rays (itself within 98-km Cyrillus crater, west of Mare Nectaris); 200-kg (dry) SLIM will take fuel-efficient route to lunar orbit taking ~3-4 months, followed by ~1 month in lunar orbit prior to surface descent; Primary mission objective is validation of vision-based navigation system with <100m accuracy; JAXA will stream launch with live coverage starting 09:00 JST (00:00 UTC)

August Moon Landings by Russia, India, Launch by Japan, Raise Major Challenges for USA

As Roscosmos readies Luna-25 / Soyuz-2.1b rocket at Vostochny Cosmodrome for launch to Moon from Site 1S reportedly set for 11 Aug 2:10 MSK (backup launch 12 Aug 2:35 MSK, landing NET 20 Aug), ISRO preps for 5 Aug 19:00 IST lunar orbit insertion / 23 Aug landing of Chandrayaan-3, and JAXA planning SLIM lander launch via H-2A on 26 Aug 09:34 JST, 21st Century USA Moon landings remain unrealized; Impact on USA world standing and space leadership may be profound if CLPS robotic landers / Artemis human Moon return are further delayed
