Accelerated Planetary Ions
Ionized atoms whose energy has been increased.
The wave that stands in front of a planet in the solar wind – similar to a bow wave in front of a boat.
Energetic Neutral Atoms
ENAs are atoms with energies greater than the planetary escape velocity. ENAs are produced by a charge-exchange process between singly-charged ions and neutral gases of the exosphere/upper atmosphere. Due to their neutrality, ENAs are decoupled from the electromagnetic fields and propagate straight forward like photons. Directional detection of the ENAs therefore yield a global image of the interaction region.
Energetic neutral atoms escaping from a planet.
The number of ions or electrons per unit of energy (eV), area (cm2), solid angle (steradians) per unit time (sec).
The outermost layer of a planetary atmosphere.
A plasma is an ionized gas, i.e. atoms from which an electron has been removed.
The ionized atmosphere of a planet.
1000 Electron Volts.
The magnetic envelope of a magnetized planet.
The larger of the 2 Martian Moons.
Shocked Solar Wind
The solar wind with reduced velocity after it has encountered the bow shock of a planet.
The flowing, ionized gas from the sun.
A plasma analyzer which instantaneously measures an energy spectra.
Supersonic Solar Wind
A solar wind that has a velocity greater that Mach 1.
