Arsia Mons

Arsia Mons rises over 20 km above the surrounding plains, is 450 km and the caldera  over 120 km in diameter. See JPL Photojournal.

Elysium Mons sunrise

An image made for the Madrid Planetarium exhibition about Mars. At left the Hecates Tholus and at the right the Albor Thorus.

Schiaparelli Crater

With a low sun the light even doesn't reach the western ridge. The Schiaparelli Crater is 450 kilometers (280 miles) in diameter.

Tharsis Montes

Arsia Mons, Pavonis Mons and Ascraeus Mons. View is southwest to northeast.

At the left Biblis Patera (left) and Ulysses Patera.

Schiaparelli Crater 2 

This rendering shows a few small valleys near the ridge, outlets formed by water streaming from the higher grounds into the large crater.

Olympus Mons (ancient)

Olympus Mons some 4 billion years ago. With water and a denser atmosphere. Made for a Madrid Planetarium exhibition.

Schiaparelli sunrise 1

The Schiaparelli Crater at sunrise. After a dust storm sun streaks are visible in the dusty atmosphere..

Northpole and Vastitas Borealis 

The Northpole (left) and the the Vastitas Borealis. The large crater at the top is the Korolev Crater 85 km (53 mi) in diameter.

Agyre Planitia and Galle Crater 

A photo of the Viking Orbiter is a famous one. (Also called The Happy Face Crater) and this is also one of the photo's of Mars which for the first time clearly showed an atmosphere.

Northpole and Vastitas Borealis

At left one of the larger craters that have a name: the Korolev Crater (about 85 km (53 mi) in diameter ).

Deuteronilus Mensae

View on the ridge of the Deuteronilus Mensae in a dust storm. The lower part behind the ridge (and the crater in the middle) is the lower Vastitas Bolearis. 

Alba Patera

A view of the Alba Patera (1600km across) from south to the north in the aftermath of a dust storm. The Caldera is at the horizon. 

Lyot Crater (Vastitas Boleares)

Some haze in the crater lightens up. At the horizon the Deuteronilus Mensae. The Lyot Crater is 236 km (~147 mi.) in diameter.

Alba Patera

An overhead view of the Alba Patera. Made for an expo of the Madrid Planetarium. At the left the caldera. Left is north and right is south.

Hellas Planitia

Hellas Planitia northern ridge.. The lower terrain is the depression which goes to about 6km depth. View from west to east.

Mars today

This image was printed together with the Noachian Mars image (below) for the July 2005 issue of National Geographic Magazine.

Mars Noachian period

Mars about 4 billion years ago. The Vastitas Bolearis filled with water, the large lake at the bottom right is the Meridiani. The Opportunity Rover found evidence of such an inner sea. Made for National Geo. July 2005 issue. 

Gusev Crater salty lake 

A  concept for NGM with the Gusev Crater in the processing of evaporating water.  A view to the south-east with the outlet Ma'adim Vallis at the right.

Gusev Crater salty lake

Visualisation of the Gusev Crater during the process of disappearing lakes. A possible view of Mars some billion years ago. About the same view as above.

Valles Marineris

Oblique view form Ius Chasma (below) to Ophir and Candor Chasma (left) and right Melas and and at the top the Coprates Chasma. 

Aram Chaos

Another concept for National Geographic. Standing body of water in the Aram Chaos. Latest findings give prove of hematite in the lower parts of the Aram Chaos.

Agyre Planitia

Concept for National Geographic: Mars during the period of loosing it's water some billion years ago. Salty deposits, cracks in the mud, forming of hematite, dust devils and falling meteors.
