Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet’s weak magnetosphere.
With each flyby, the BepiColombo mission gets another boost of energy for its eventual orbital insertion around Mercury.
A cloud of dust traces the innermost planet’s orbital path. By all accounts, it shouldn’t be there.
Image pairs indicate that 99% of the planet’s surface could be altered in the next 25 million years.
MESSENGER observations show a 50% rise in atmospheric sodium-group ions during periods of high solar wind activity.
A new measurement of plasma density distribution in Mercury’s magnetosphere obtained from observations of field line resonance events provides necessary constraint for many planetary science issues.
BepiColombo may launch as early as this weekend. It seeks to unravel the mysteries of Mercury’s geologic and magnetic past and map the small planet’s cratered surface.
New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.
An analysis suggests that craters degrade faster on Mercury than the Moon, raising questions about landscape evolution on different planetary bodies.
Researchers make the first short-term observation of sodium flares in Mercury’s exosphere.
