Terraforming Mars Isn't a Climate Problem—It's an Industrial Nightmare Even when the idea of terraforming Mars was originally put forward, the idea was daunting. Changing the environment of an entire planet is not something to do easily. Over the following decades, plenty of scientists and engineers have looked at the problem, and most have come to the same conclusion - we’re not going to be able to make Mars anything like Earth anytime soon. A new paper available in pre-print on arXiv from Slava Turyshev of NASA’s Jet Propulsion Laboratory, is a good explainer as to why.

3D image shows a slope of layers throughout the entire scene. This is a smal part of Candor Chasma, within the giant Valles Marineris canyon system on Mars. The scene is less than 5 km, or 3 miles, across.

HiRISE 3D: In Candor Chasma

These layers are well-exposed over a wide range of elevations. And also look spectacular in 3D.

HiPOD: Boundary Boulders

With the resolution of HiRISE we can see that the reason one side of the boundary is darker than the other is due to the many boulders strewn across the darker side.

HiPOD: Varied Types of Rock in a Crater in Eos Chasma

This image shows a crater on the floor of Eos Chasma, part of the Valles Marineris canyon system. Craters on Mars are useful for geologists because they provide cross-sections into the subsurface.

3D image shows an impact crater with a very eroded rim on the Sorth Polar layered deposits of Mars. The scene is less than 5 km, or 3 miles, across.

HiRISE 3D: A Crater on the Sorth Polar Layered Deposits

This crater has not been imaged in HiRISE before, and obtaining a diameter measurement will improve knowledge of age and accumulation rate of the SPLD.

HiRISE 3D: Monitoring Wind Streak and Intracrater Dunes

We obtained this image four Mars years after earlier stereo in 2007. This anaglyph would allow paired DTMs to be constructed with the previous one to assess changes.

HiPOD: The Upper Section of a Channel in Gale Crater

This observation features an upper section of a canyon channel system that incising Mount Sharp in Gale Crater. A HiRISE image was requested as the canyon system is analogous to Gediz Vallis.

3D image shows a large mound rising above otherwise flat terrain that is likely an ancient flow of some kind. The scene is less than 5 km, or 3 miles, across.

HiRISE 3D: A Flow Obstacle in a Debris Apron

Our goal here is to investigate flow dynamics around what might be a “nunatak.” On Earth a nunatak is an isolated mountain peak that once projected through a continental ice sheet.

HiPOD: The Upstream Edge of a Crater in Athabasca Valles

This image provides a closer look at lava-topography interactions in this area. Athabasca Valles is a young outflow channel system on Mars that may have been carved by catastrophic water floods.

HiPOD: Those Transversing Dunes

This wonderful image was acquired to study basin-driven wind regimes with what the suggester termed an “epic Argyre rim dune field under adiabatic flow.”

HiPOD: Glacial Flow Meets Central Pit

This observation features a thin glacial flow into an impact crater’ central pit. This image can be useful for constraining ice dynamics. Additionally, differential erosion of the crater slopes is also visible.

3D images shows a large flow feature that extends across the width of a very ancient and eroded impact crater. There is a small breach in the rim at one point. The scene is less than 5 km, or 3 miles, across.

HiRISE 3D: Viciously Viscous

Perhaps “vicious” is too harsh. Here we see a glacial like flow lobe crosses this crater floor from the northeast to southwest.

3D image shows a shallow depression, a constriction, in part of the terrain in Grjota Valles on Mars. There is also a large mound within the constriction. The scene is less than 5 km, or 3 miles, across.

HiRISE 3D: In Grjota Valles

This image shows a constriction in Grjota Valles, eroded by water or lava but now filled by lava. Topography of locations like this provides useful constraints on the dynamics of water and lava flows.

Image cutout shows a large depression called a graben on the surface of Mars. The floor of the depression appears relatively smooth. The sides of the graben appear to have layering.

Enhanced color cutout shows a closeup of one of the graben walls, that expose the layers in better resolution. Some of the layers are light-toned in color.

HiPOD: Layering in a Graben Wall

A short but elegant rationale: “nice layering apparent in Mars Orbiter Camera images, worth a closer look for regional stratigraphy.” Graben are depressions that form along parallel faults due to tectonic extension.

Image cutout shows a very large and dark dune field on the surface of Mars. There are ripples and gullies on the dunes as well as visible dust devil tracks throughout the scene, which is less than 5 km (3 miles) across.

HiPOD: Landscape Evolution

This overlaps with a previous image we obtained in 2009 and we have also taken six additional images to monitor gully formation. We want to see how any dune ripples have moved since then.
