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
