Mission Cadence to/from LEO at All Time Peak as 2 Space Stations Conduct Operations
ISS (51.6° inclination, 405-km orbit) is busy: Soyuz MS-18 is to relocate from Zarya docking interface Rassvet / Mini-Research Module 1 to Zvezda / Multipurpose Laboratory Module on Sep 28, allowing Soyuz MS-19, launching Oct 5 carrying Russian director Klim Shipenko, actress Yulia Peresild and Flight Commander Anton Shkaplerov (Roscosmos) to occupy Rassvet berth. After filming scenes for film Vyzov (Challenge), Shipenko and Peresild are scheduled to return to Earth on Soyuz MS-18 on Oct 17. Meanwhile CRS-23, the 3rd SpaceX mission contracted under NASA Commercial Resupply Service phase 2 (23rd overall), is to undock from ISS Harmony module September 30 for Earth return via Gulf of Mexico Splashdown. Newly arrived Tianzhou 3 mission, launched to Tiangong space station (41.5° inclination, 370-km orbit) from Wenchang SLC on LM-7, ready to support Shenzhou-13 human mission with supply of EVA, fuel, science experiments and equipment (5,600kg total). Shenzhou 13 is expected to launch 3 Taikonauts within Oct 15-18 window from Jiuquan SLC on LM-2F to TSS, beginning standard 6-month duration mission sequence. Looking to deep space, Human Moon missions are also on the horizon: Chief Long March rocket designer Long Lehao is expected to announce details on LM-5DY variant at China International Aviation & Aerospace Exhibition in Zhuhai, Guangdong Sep 28 to Oct 3; USA VP Kamala Harris expected to announce space priorities / convene National Space Council within the month.(Image Credits: CNSA, NASA, Roscosmos, SpaceX)

Marking its 3rd full year in space October 20, BepiColombo is set to perform its first Mercury periherm Oct 1. Named after scientist Giuseppe “Bepi” Colombo who first proposed interplanetary gravity assist maneuvers, the ESA / JAXA mission consisting of 21 science instruments aboard 2 orbiters (Mercury Planetary Orbiter and Mercury Magnetospheric Orbiter dubbed Mio), is planned to complete 6 Mercury flybys before entering orbit December 5, 2025. At least 1 year of science will study Mercury solid and liquid iron core, tenuous surface-bounded exosphere, gravity and magnetic fields, and work to confirm the existence of water ice which was observed by MESSENGER nearly a decade ago. While Mercury is the closest planet to the Sun, Astronomers in Chile recently located 1-km diameter asteroid (2021 PH27) traveling in an inclined orbit coming within 20M km of Sol every 113 days, reaching 500° C. Being tidally locked with an perihelion of 0.307 AU (~46M km), Mercury surface temperatures range from −173° C at night to 427° C during the day, with polar regions remaining below −93° C. The permanently shadowed craters are thought to be slowly accumulating water molecules from energetic reactions between the hydroxyls in surface minerals and solar wind. The 1st surface mission, if funded, could be the proposed US$1.2B Mercury Lander launching on a Falcon Heavy March 2035.
