The closest planet to our sun, Mercury, experiences extreme temperature variations. Since the planet has no atmosphere to speak of, it is in a constant cycle where one side is extremely hot and the other extremely cold. On the sun-facing side, temperatures reach a scorching 427\u00b0C (800\u00b0F), enough to melt tin and lead, and the surface is exposed to extremely lethal levels of radiation. On the night side, temperatures plunge)] to a chilling \u2212173\u00b0C (−279.4\u00b0F), cold enough to freeze most liquids, including those used in battery manufacturing.<\/p>\n

All of this makes exploring Mercury\u2019s surface very challenging. On the one hand, a rover would be subject to interference from the sun\u2019s radiation on the sun-facing side and would likely melt down. On the other hand, a solar-powered rover cannot operate on the night side, and a battery-powered vehicle would likely lose power quickly as its batteries die. But in the Terminator, the region between night and day on Mercury, temperatures are stable enough, and there is sufficient light for a solar-powered rover to study surface features and conduct science operations.<\/p>\n

This is the proposal put forth by a research team from the Hawai\u2019i Institute of Geophysics and Planetology (0HIGP) at the University of Hawai\u2019i at M\u0101noa. The team included Mari Murillo, a Planetary Science Ph.D. Student at HIGP, and Paul G. Lucey, a prominent researcher with HIGP and Murillo\u2019s Ph.D. advisor. The paper detailing their proposal was presented at the 2026 Lunar and Planetary Science Conference (2026 LPSC).<\/p>\n","protected":false},"excerpt":{"rendered":"
