India, Russia and Japan Craft Prepare to Join China Landers Operating on Moon
China will reach 10 years of continuous activity on the lunar surface December 14, and Chang’E-3/4 should finally have company at that time. ISRO Chandrayaan-3, now separated from propulsion module, is zeroing in on landing site ~20 km west of Manzinus U crater (69.368°S, 32.348°E). ISRO operators work to finish landing system firing tests from 153 x 163 km polar orbit ahead of 2 deorbiting maneuvers which will bring Chandrayaan-3 into an elliptical 30 x 100 km landing orbit. If all goes as anticipated, touchdown to occur NET August 23 at 12:17 UTC. Science instruments on Vikram lander which will be utilized over the 1-lunar day nominal mission (14-Earth days) include plasma density sensor RAMBHA, ChaSTE thermal sensor, ILSA seismometer, and a passive retroreflector array supplied by NASA, while Pragyan rover carries an X-ray spectrometer and a laser spectroscope. Roscosmos Luna-25 may already be in the vicinity when Chandrayaan-3 lands, having achieved lunar orbit insertion Aug 16 and targeting landing at 69.545°S, 43.544°E, ~50 km northeast of Boguslawsky crater NET Aug 21, 23:10 UTC. Luna-25 carries 8 instruments including STS-L panoramic / local imager, ARIES-L plasma sensor, LASMA-LR mass spectrometer, LIS-TV-RPM infrared spectrometer and a retroreflector. Not to be left out, Japan is also launching Smart Lander for Investigating Moon (SLIM) with Lunar Excursion Vehicle 2 rover to a site ~500 m east of Shioli crater (13.33°S, 25.23°E) NET Aug 26, aiming to achieve 100-m landing accuracy.

ISS: Humans Continuously in Space; SpaceX and Soyuz Launches
In space human activity continues as SpaceX Crew 6 with Andrey Fedyaev, Woody Hoburg, Stephen Bowen and Sultan Alneday prepare to leave ISS at the end of August after a 6-month mission, conducting over 200 experiments to help prepare for future missions to Moon, Mars and beyond. Crew 7 is scheduled to launch no earlier than 02:45 EDT August 25 with international Astronauts Jasmin Moghbeli (NASA), Andreas Mogensen (ESA), Satoshi Furukawa (JAXA), Konstantin Borisov, (Roscosmos) for a 6-month mission, the 11th overall crewed orbital flight. They are scheduled to dock to the orbiting laboratory about 03:49 EDT Aug 26, to the space-facing port of the Harmony module. SpaceX Crew Dragon Endurance Spacecraft marks the eighth human spaceflight mission supported by a SpaceX Dragon spacecraft and the seventh crew rotation mission to the space station since 2020 for NASA. Russia also plans Aug 23 launch of resupply mission Soyuz 85th Progress cargo delivery ship to ISS. It is preceded by successful launch in May of Progress 84 resupply cargo freighter carrying about 2,500 kg of supplies including experiments, fuel and food to support crew of Expedition 69. ISS has been continuously occupied since November 2000 with Astronauts testing technologies, conducting science experiments, developing skills needed to operate future commercial destinations in low-Earth orbit for the benefit of all.
