Would terraforming Mars affect its gravity?

Chris Howlet

No, gravity is influenced very much by the mass of the object in question. This means that, in order for the gravity of Mars to be affected, we would somehow have to either add mass to the Red Planet or take it away. Terraforming Mars – that’s making it more hospitable for human habitation – does neither of these things.

Instead, terraforming Mars involves the incredible feat of building up its atmosphere, keeping the globe warm and keeping that atmosphere from being lost to outer space. Mars’s gravity (which is 38% that of Earth’s) combined with its questionable

U.S. closed access to its market technologies from China

The U.S. Congress passed a new law prohibiting the purchase of any process equipment in China. Beijing criticized Washington's initiative and assured that such measures will benefit the development of bilateral relations.

The new ban will affect first of all the departments of Justice and Commerce, as well as affect NASA. These institutions are no longer able to buy the Chinese information technology equipment without the approval of the federal government. Thus, the new initiative does not explicitly restrict buying IT systems in China, but greatly complicates the process, explain the American media.

Australia: Drought negatively affect future productivity and quality of wheat

May 29, 2013. Australian wheat harvest this year may suffer from lack of moisture, predicts Emerald Group Australia Pty. It is reported by news agency Bloomberg.

It is currently summer in Australia was unusually hot. The rainfall from February to April was below normal, leading to a reduction in soil moisture reserves. In April, Australian farmers have started sowing winter, hoping to heavy rainfall during the winter.

Lack of moisture will negatively affect the quality of the wheat, predicts Emerald Group Australia Pty. Wheat yields in some grain-producing areas will be lower than expected earlier, and wheat yield will be

The climate of New South Wales raises concerns

May 14. Scientists are seriously concerned about the climate in the state of New South Wales (NSW), where one third of the inhabitants of Australia. 31% of the national economy is concentrated in this state. Over the past 40 years in NSW have increased significantly in duration and intensity of droughts and heat waves in western Sydney marked increase in the number of warm days of the year by 60%.

Experts estimate that by the end of the century the largest city in Australia, the number of days with temperatures above 35 ° C will be 14 compared to the

A cup of coffee — a pleasure or an environmental disaster?

A cup of coffee — a pleasure or an environmental disaster? It is interesting

As it turned out, the western part of the Pacific coast may be the main supplier of caffeine pollution in the ocean, as in the countries located on it, coffee has played an important role in everyday life. The effect on marine life from coffee residues containing a powerful tranquilizer, can be unpredictable.

Proven that caffeine from sewage in Oregon, USA, easily falls in sea water, and in the current near the mouth of the river. Moreover, the level of pollution in bodies of

Climate change will affect the nature of the storm

Climate change will affect the nature of the storm Scientists prove

Many climate scientists are doing research on how climate change will affect the individual components of the weather, such as clouds, precipitation, lightning, nature, etc. Thus, in the Tel Aviv University found that for every degree of warming in the future will have 10% more lightning during thunderstorms than usual.

As the climate model and the available examples of acute cycle of El Niño in Indonesia and Southeast Asia, the increase in the intensity of storms take on a momentum negative effects and increase the risk of

How will climate change affect the situation with fires? It is interesting

Over the next 30 years due to the increase in global temperature is expected to increase the number of fires on Earth. Very often they will occur in the western part of North America, according to the Texas Tech University.

Burning in Portola Hills, California, USA. Combining data from 16 climate models in the world, and satellite data, scientists have a global perspective of the spread of fires and their relationship to modern climate. By the end of this century, almost all of North America and

Wind farms can affect climate change

Wind farms can contribute to climate change Scientists have shown

According to new research, wind farms can influence the Earth's climate. To be precise, the new technology of obtaining energy involved in the increase in global temperature.

Usually at night the air closest to the earth's surface to several meters in height and more cold. Due to this cool and the soil itself. But near the large wind farms, where the turbine blades are constantly working, warm air from higher layers goes down and causes a general rise in temperature. It sounds quite convincing, because based on this principle, some
