Some rather striking cardigans have been seen on an usual set of Shetland residents – Shetland Ponies. Posing in their winter woollies, the ponies were marking the Year of Natural Scotland by sporting some rather plush knitwear that wouldn’t seem out of place in any trendy city hangout.

It’s safe to say both Fivla and Vitamin didn’t seem to mind all the attention their custom made attire brought them.

Terrformation of Mars: A New Look

We look at Mars now as a forgotten Red Planet that almost seems barren and life-less judging from our available images and study of it. But study shows Mars was once as ecologically prosperous as our own Earth. But what happened to all of its waters? Better yet why is it so dry and lacking any plants? Once the abundance of oxygen left and the waters froze over or dried off the planet became what it is today. But what if we can in a way reactivate’ Mars? Welcome to Mars, Terraformed’.

About Terraforming

Transforming Mars will be a long and complicated process. But this is exactly the type of subject that interests space researchers like Christopher McKay of NASA Ames Research Center. First, greenhouse gases, like chlorofluorocarbons that contribute to the growing ozone layer on Earth, will be released into the atmosphere. This traps the heat from the Sun and raises the surface temperature by an average of 4 degrees Celsius. In order to achieve this, factories would manufacture chlorofluorocarbons derived from the air and soil. A single factory would require the power equivalent of a large nuclear power plant.

The increasing temperature would vaporize some of the carbon dioxide in the south polar cap. Introducing carbon dioxide into the atmosphere would produce additional warming, melting more of the polar cap until it has been vaporized completely. This would produce an average temperature rise of 70 degrees Celsius.

With the temperature this high, ice will start melting, providing the water needed to sustain life. This water would raise the atmospheric pressure to the equivalent of some mountaintops. While this would be a survivable level, it may still require the use of an oxygen mask. The next step, which may take up to several centuries, would be to plant trees that thrive on carbon dioxide and produce oxygen.

NASA: Terraforming Mars

Terraforming is the process of transforming a hostile environment into one suitable for human life. Being that Mars is the most Earth-like planet, it is the best candidate for terraforming. Once just the subject of science fiction novels, it is now becoming a viable research area. The famed astronomer and Pulitzer prize winner, Carl Sagan, says that there is enormous promise in the search for ancient life on Mars. If life was once sustainable on Mars, it is important to know what caused Mars to evolve into the cold and lifeless planet it is today. With this knowledge, we can terraform Mars by reversing the process.

NASA scientists believe that it is technologically possible at the present time to create considerable global climate changes, allowing humans to live on Mars. But this will not be by any means an easy task. Raising the atmospheric pressure and surface temperature alone could be achieved in a few decades.

This research has strong environmental implications for Earth. What researchers are trying to do involves global warming, a sort of greenhouse effect on the cold planet Mars. Scientists may be able to test their hypotheses about global warming in their attempts to elevate Mars’ surface temperature. Likewise, once theories, they may be applied to our own planet in an attempt to reverse environmental damage done by pollution and deforestation.

We find out the heart only by dismantling what
the heart knows. By redefining the morning,
we find a morning that comes just after darkness.
We can break through marriage into marriage.
By insisting on love we spoil it, get beyond
affection and wade mouth-deep into love.

While there is a lot of appropriate rage about Ferguson right now, the killing of John Crawford, III is getting less attention than it deserves. I put Shaun King’s tweets and history lesson on the matter in chronological order for easier consumption.

Red-mouthed Conch - Conomurex luhuanus

Also known as Strawberry Conch, and Blood-mouthed Conch, Conomurex luhuanus (Littorinimorpha - Strombidae), was formerly named Strombus luhuanus. It is a sea snail with robust shells up to 80 mm found in the Indo Pacific waters. Most specimens have an orange-red aperture, hence the common name. A few, however have apertures either yellow or pure white.
