Mars from Earth
Last month, Mars and Earth were right next
to each other in their orbits.
Formally called
opposition, the event was highlighted by a
very bright Mars for skywatchers
and a good photo opportunity for the
Hubble Space Telescope.
Above, Hubble snapped the
highest resolution picture of Mars ever obtained from the
Earth.
Visible on
Mars are
ice caps over the poles in white,
regions covered with sand and gravel
in dark brown and orange, and
large dust storms in light orange.
A particularly
large dust storm
can be seen on the lower right pouring out of
Hellas Basin.
This storm has since
erupted into a huge planet wide storm
that continues even today.
Pictures like these allow
planetary astronomers to continue to
compare the
weather patterns of
Mars and Earth.
When Mars next
reaches opposition in 2003, its elliptical orbit will cause it to be even 20 percent closer.
