Colonies take root

Cabot led another voyage to the Americas the following year but nothing was ever heard of his ships again. This effort was rebuffed and later, as the Anglo-Spanish Wars intensified, Elizabeth I gave her blessing to further privateering raids against Spanish ports in the Americas and shipping that was returning across the Atlantic, laden with treasure from the New World. By this time, Spain had become the dominant power in the Americas and was exploring the Pacific Ocean, Portugal had established trading posts and forts from the coasts of Africa and Brazil to China, and France had begun to settle the Saint Lawrence River area, later to become New France. English overseas possessions InElizabeth I granted a patent to Humphrey Gilbert for discovery and overseas exploration.

Colonies take root

But is the Red Planet really the best target for a human colony, or should Colonies take root look somewhere else? Should we pick a world closer to Earth, namely the moon? The Red Planet has an atmosphere containing carbon dioxide, which can be converted into fuel while also supporting plants that can make food and oxygen.

These features could allow Martian colonists to be self-sufficient.


Over decades, continued expansion in that vein could achieve something called paraterraforming. This means creation of an Earthlike environment on the Mars surface that could include not only farms but also parks, forests, and lakes, all enclosed to maintain adequate air pressure.

While the small spacecraft in which astronauts fly today carry food and oxygen as consumables and use a simply chemical method to remove carbon dioxide from the air, this type of life-support system will not swing on a colony.

As on Earth, air, water, and food will have to come through carbon, nitrogen, and water cycles. This means engineering the planet enough to support humans and other Earth life without domes and other enclosed structures.

Terraforming Mars would require that the atmosphere be thickened and enriched with nitrogen and oxygen while the average temperature of the planet must be increased substantially. To get started, terraformers might seed the world with certain microorganisms to increase the amount of methane in the Martian air, because methane is a much stronger greenhouse gas than carbon dioxide.

They also would seed dark plants and algae across the surface, thereby darkening the planet so that it absorbs more sunlight. With the right combination of plants and well-selected microorganisms, planetary engineers could generate the needed oxygen and nitrogen.

During all of the centuries needed for terraforming, colonists would inhabit and expand the system of paraterraformed structures. Still, there are some aspects of the plan that are less than ideal — and indeed, might point our skyward gazes toward a different destination altogether.

The Problem of Distance A colony totally isolated from Earth would need significant genetic diversity to avoid the disease risks that plague smaller populations.

According to a study published earlier this year, a multi-generation starship carrying people whose descendants would colonize a planet orbiting a nearby star would need a population of at least 10, and possibly closer to 40, This certainly would fulfill the population requirement, but a further distance is a challenge both in fuel and in time.

The Musk plan involves sending multiple crafts each with a total payload of 15 tons per trip.

This gives us a ratio of approximately 5 tons per person. Some of the tonnage is due to the fuel needed to accelerate the ship from low Earth orbit to escape velocity, and this may not differ between Mars and closer sites, such as the moon.

Second, the time it takes to transport settlers.Key Events Chapter 3 Colonies Take Root () What You Will Learn In the s, England started colonies in North America that were influenced by religious beliefs. I use chicory root when cooking, as it is an excellent source of antioxidants, as well as a terrific system cleanser.

Most of my chicory consumption comes via kimchi, as it’s an ingredient I use when making kimchi at home (and you can find the recipe in Brain Maker).
