Mapping the Sun's Interaction with Mercury's Surface
Tucson AZ (SPX) Sep 15, 2023 A new study maps the infall of protons and electrons from the solar wind to geographical location on the surface of Mercury, giving scientists new insight into how interactions with the Sun alters the surface and produces Mercury's very thin atmosphere. "Studies that have examined the infall of protons and electrons from the solar wind typically map the infall to the surface in terms of time-of-day (dawn, noon, dusk) and not in terms of geographic location (longitude). This is one of the first pap ... read more |

Mercury ahead
Paris (ESA) Oct 01, 2021 The ESA/JAXA BepiColombo mission to Mercury will make the first of six flybys of its destination planet on 1 October before entering orbit in 2025. Hot on the heels of its last Venus flyby in August, the spacecraft's next exciting encounter is with Mercury at 23:34 UTC on 1 October (01:34 CEST 2 October). It will swoop by the planet at an altitude of about 200 km, capturing imagery and science data that will give scientists a tantalising first taste of what's to come in the main mission. The ... read more
