Mars Aerial and Ground Global Intelligent Explorer or MAGGIE is a proposed compact, autonomous, fixed wing, vertical take-off/landing (VTOL), electric aircraft powered by solar energy. It is designed to operate on Mars. Range with a fully charged battery would be 179km (111miles) at an altitude of 1,000 meters. The aircraft features solar cells on its wings and fuselage. The total range per Martian year would be 16048km (9,972miles). Mars' atmosphere density is 6.35 mbar,[1] 160x thinner than Earth's atmosphere at 1013.2 mbar.[2] During the southern winter, the global atmospheric pressure on Mars is 25% lower than during summer, because some atmospheric freezes on the Martian polar ice caps. MAGGIE has a cruise lift coefficient CL of 3.5, nearly an order of magnitude higher than conventional subsonic aircraft, to overcome the low density of the Martian atmosphere.[3] [4] MAGGIE's cruise Mach number is 0.25. Mach speed on Mars is 546.4 mph at "sea level", so cruising speed would be around 130 mph at elevation.[5]
In January 2024, MAGGIE was one of thirteen proposals approved for Phase 1 funding by the NIAC.[6]
