Exploring Mercury's Plasma Environment
Release Date: June 21, 2011
Topics: EPPS, MAG



Date Presented: June 21, 2011, in a MESSENGER Science Highlight article.

Of Interest: Plasma and magnetic field observations made during the near-Mercury parts of the orbit shown in Figure 3 in the Science Highlight article. The top panel shows proton plasma measurements from FIPS; the color scale denotes the total flux of these particles within a given interval of energy per charge. The second panel shows heavy ions within different ranges of mass per charge (m*), also measured by FIPS. The third panel shows MAG measurements of magnetic field strength. The bottom panel shows MESSENGERís altitude during passage near the planet, measured in units of Mercuryís radius.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet.
