Mars Lights and Lightning

More electrical activity has been
detected on the Red Planet.
According to a
previous Picture of the Day,
Martian aurorae have been discovered
that are centered on
regions near the South Pole.
Although Mars has no intrinsic
magnetic field, it does possess
concentrated bands of crustal
magnetism in its lower latitudes.
Electric Universe explanations
notwithstanding, planetary
scientists do not know what caused
the peculiar magnetized stripes that
seem to focus on a specific point in
the south, or why the auroral events
should be associated with them.
Recently, NASA investigators
announced that they have
detected "non-thermal radiation"
from the Martian surface. Since the
energy readings were independent of
the surface temperature, and
occurred during one of the giant
dust storms that sometimes rage
through the southern plains, the
assumption is that they are evidence
for lightning discharges.
The dust storms that occasionally
engulf an entire hemisphere of Mars
have been discussed several times in
the past. They have been identified
with dust devils—really tornado-like
whirlwinds whose tops are higher
than Mt. Everest—that appear to draw
finely divided dust up through
thousands of funnels and carry it
for hundreds of kilometers. NASA
scientists assume that the
synchrotron radiation they detected
was caused by electric charge build
up in the sand grains that
subsequently discharged as
lightning, but that may not be the
case.
What causes Martian dust storms and
why are they electrified? The air is
100 times thinner on Mars and
averages 75 degrees colder than
Earth. The environment appears to be
bone dry, with only some suggestive
experiments by the Phoenix lander to
indicate the possible presence of
water ice. Yet Martian dust storms
are larger than any seen on Earth.
Occasionally, when Mars is closest
to the sun, dust obscures the whole
planet.
When NASA studied dust devils in the
Arizona desert in order to
understand more about the ones that
have been seen on Mars, they found
an electric field of up to 10,000
volts per meter associated with dust
devils on Earth. The normal fair
weather electric field at the
Earth's surface measures 100 volts
per meter. This suggests that dust
devils on both Earth and Mars are
atmospheric electric discharge
phenomena similar to the electric
breezes produced by "ionic wind" air
purifiers
In the Electric Universe theory, no
collisions from bouncing sand grains
are necessary. Charge separation
already exists in the atmosphere.
Without clouds like those on Earth
to send lightning down to ground
level, the electric discharges on
Mars form giant whirlwinds that are
part of an interplanetary electrical
circuit. It is that same circuit
that drives weather systems on
Earth. If this is true, then Martian
“dust devils” and those on Earth are
both illustrations of how
electricity behaves in the solar
system.
Electrons spiraling in a magnetic
field will emit synchrotron
radiation, the most common type of
"non-thermal" radiation. Whirling,
electrically charged dust storms,
spinning at hundreds of kilometers per
hour, create intense magnetic fields
that tend to confine the charged
particles and accelerate them around
the vortex at high speed. Rapid
acceleration, coupled with high
voltages in the dust causes the
electric glow seen recently on Mars.
