Many space artists have depicted terraforming scenes in their work.

Mars, as terraformed by Michael Carroll. If we really could come up with all that water, it would drain to the northern plains and form an ocean covering up to 25% of the planet.

 

In 1991 this image was used on the front cover of the 'Making Mars Habitable' issue of Nature.

 

A terraformed Mars as seen from Phobos, by David A. Hardy. This picture was used for the front cover of Arthur C. Clarke's book 'The Snows of Olympus: A Garden on Mars.'

 

Aerial exploration of a dry valley on Mars. This painting, by David A. Hardy, depicts the dirigible airship Arrowhead described in Kim Stanley Robinson's novel 'Red Mars'.

 

Designed as a cover, the picture graced the front of Interzone as well as that of an edition of the novel itself.

Stan Robinson described the Arrowhead as being 100 m long and 120 m wide across the wings, with a pencil-shaped gondola extended under most of the length of the underside.

 

Flight is achieved in the thin air on Mars by buoyant hydrogen within the body of the craft, lift from the wings and turboprops at each wing tip and under the gondola.

 

Another book cover by Hardy for Carl Sagan's 'Pale Blue Dot'.

 

Again, we see Mars from Phobos: a planet at an advanced stage of terraforming with the Tharsis volcanoes, a flooded Mariner Valley and the Boreal Ocean clearly and accurately portrayed.
 

Another nice image of a terraformed Mars, look at the clouds and the blue of that sea!
 

 

Fantastic images of the "Tharsis" and "Hellas" hemispheres of a terraformed Mars, rendered as if viewed from the altitude of Deimos's orbit.
 

I love the detail such as an ice cap atop the Tharsis bulge and the green of vegetation on the shores of the Hellas and Isidis Seas.
 

This well known painting by Michael Carroll depicts a "Terraforming Survey Team" examining an ecosystem taking root on Mars. Planetary engineering is evidently boosting the atmospheric pressure: hence the wearing of masks instead of full pressure suits.
 

On the shores of the Great Boreal Ocean, beneath a blue sky. The ultimate dream of some terraformers: making a home of Mars.
 

The Mars Worldhouse: a quasi-global building conceived by Richard Taylor as a rapid solution for "paraterraforming " Mars.

These next two images come from the Millenium Mars Calendar by James M. Graham and Kandis Elliot: a calendar spanning one Mars year, divided into 20 "months", and based on a terraforming theme.
 

A research vehicle explores summer at the South Pole of Mars by venturing into one of the wind-eroded canyons in the ice cap.

 

A valley system on Mars begins to flood as terraforming proceeds. Fluvial erosion is seen on the Red Planet again for perhaps the first time in a billion years.

 

A cylindrical projection of the terraformed Mars that results in Kim Stanley Robinson's novel "Blue Mars".

 

Superb rendering of a terraformed Mars showing Tharsis, the North Polar Cap and the flooded Chryse Basin to the East. Notice the light of settlements on the dark hemisphere.
 

The availability of 3D landscape rendering software, allows amateurs to have a go at this art-form.

A Zubrin statite mirror cluster warms the South Pole of Mars in order to liberate its frozen atmosphere.

 

It is possible that substantial water reserves might be released during terraforming by drilling into pressurized aquifers beneath the northern plains. Here, from the crest of the southern uplands, we see a huge geyser erupting in the distance. frost is already condensing nearby.
 

Illustrations of more exotic planetary engineering projects are welcome

Believe it or not, but it is just possible to terraform the Earth's moon, so long as you are prepared to keep its imported volatiles topped up every few thousand years or so!

 

It is probably impractical, but what a fine sight such a blue moon would be from the surface of the Earth.

 

A supramundane planet under construction over Jupiter according to the concept of Paul Birch.

 

The vast habitable strip over the tropical regions, supported by a cage of dynamic compression members, could be extended to englobe the entire planet. Built at the 1 g level, its surface area would be up to 316 Earths.
