In the years from about 1890 to about 1910 Percival Lowell became enamored with the observations of Schiapereli. Canalifor him were canals. He believed in canals and the intelligent life forms needed to dig them. He spent many years talking and writing about them.

The interior of Mars has not been studied by seismic waves. Surface clues indicate that the interior as shown is likely correct. Over time the interior has cooled and vulcanism has ceased.

Surface Features

The surface of Mars has been imaged and mapped at least as thoroughly as the Earth.

No liquid water has been found although there is much evidence that there has been standing and flowing water in the past.

The Southern Hemisphere is somewhat higher in elevation and covered with craters appearing much like The Moon.

The lower Northern Hemisphere is much more earthlike. It has giant volcanoes and canyons.

The North Polar Cap seems to have water ice with much dry ice covering it. There is much information in the apparent layers that have accumulated over eons.

The South Polar Cap seems to have less water ice and less layering.

Robots to Mars

From the Mariner Probes in the early ‘60s to the extremely successful Phoenix Lander 2010 mankind has sent variety of robot orbiters and landers to prepare the way for a future manned mission to the exotic Red Planet.

One of the trickiest parts of the Mars Exploration is actually getting the rovers to Mars in working condition.

Imagine trying to drop a sophisticated robot about 11-12 stories without breaking it (or even dropping an ordinary DVD player)

This is a view from Opportunity down into Victoria Crater. It spent nearly a full Earth year finding the best way down into the crater and this is it. Opportunity has now left Victoria Crater in search of another crater to explore.

Intrepid Geologists

Discoveries

  • Adventures

    - Stuck in sand dune

    • Covered by dust in a storm

    • Uncovered by a whirl wind

    • Lived through a long Mars winter

    • Are still going strong (four times as long as expected)

  • Layering as if by water deposit

  • Spherical pebbles such as in a stream

  • Rust (color) same as the red iron oxide as in Southern Utah

Phobos (Fear) is the large of the two. They are both tiny and badly scarred by impacts but Phobos looks like it was nearly shattered.

The Japonese are planning to send a robot to pick up dirt and rock samples from Diemos (Terror) to return them to Earth
