Inner Solar System Exploration Progresses with BepiColombo Mercury Flyby, Upcoming Venus Missions

ESA / JAXA joint mission BepiColombo is set to make its 3rd Mercury flyby on June 20. Three additional flybys are scheduled (Sep 5, 2024; Dec 2, 2024; Jan 9, 2025) before insertion into Mercury orbit on December 5, 2025. From orbit, the BepiColombo craft will separate into its constituent elements – first the ESA-built Mercury Transfer Module propulsion module will detach from Mercury Magnetospheric Orbiter Mio (JAXA) and Mercury Planetary Orbiter (ESA), followed by the two science modules uncoupling via spin eject. MPO will operate 11 instruments from a 480 × 1,500 km orbit, while Mio will observe with 5 instruments from 590 × 11,640 km, both with a polar inclination. NASA Parker Solar Probe to reach 16th perihelion (~ 13 R☉ / 9 Gm) on June 22. Data from this distance has already provided new understanding of magnetic interactions which create coronal holes and solar wind. Parker is also making its 6th Venus flyby on August 21, while ESA Solar Orbiter isn’t due in Venusian proximity for its 4th flyby until Feb 18, 2025. JAXA Akatsuki is the sole craft currently observing Venus, from a highly elliptical 1,000 – 370,000 km orbit, with several missions working to join: ISRO Shukrayaan-1 may launch NET December 2024, Rocket Lab / MIT targeting January 2025, CNSA VOICE 2026, UAESA mission 2028, NASA DAVINCI & VERITAS, Roscosmos Venera-D 2029, and ESA EnVision 2031 (Image Credits: ESA, JAXA, NASA)
