ABOUT BEPICOLOMBO
BepiColombo is a joint ESA/JAXA mission to Mercury carrying two science orbiters. It uses the most complex gravity-assist trajectory ever flown, with 9 planetary flybys including one of Earth, two of Venus, and six of Mercury before orbit insertion in December 2025. It will study Mercury’s magnetic field, surface, and internal structure.
TECHNOLOGY & FIRSTS
- Two orbiters stacked during cruise phase
- Uses solar-electric propulsion + 9 gravity assists
- Most complex gravity-assist trajectory ever flown
