Why are asteroids valuable?
While scientists study asteroids to better understand the formation of the solar system and humanity’s origins on this rock we call home, asteroids could become economically valuable as well. Asteroids often contain important metals such as iron, nickel, and cobalt, as well as small amounts of precious metals such as platinum (Figure 2). Given these considerations, a single asteroid with the right composition could be worth trillions of dollars in raw materials.
What companies are mining asteroids?
Currently there are two known companies with a long-term focus on asteroid mining: Planetary Resources and Deep Space Industries (DSI), founded in 2010 and 2013, respectively. Planetary Resources raised $21 million this year to launch satellites with sensors to help manage natural resources on Earth. They plan to use this technology to eventually scan from afar near-Earth asteroids to identify desired materials. Within a decade, they and DSI hope to send survey probes to asteroids to map their surfaces and collect samples. Both companies hope to determine the best asteroids for mining of not just metals but also water ice that can be “ converted into drinking water, breathable air, and rocket propellants ” for use in a space economy. The ultimate goal is to use fully automated robotic systems for mining, processing, and transporting products wherever they are desired, whether on Earth or in space.
What is the most important treaty for asteroid mining?
The most important treaty for asteroid mining is the 1967 Outer Space Treaty, which establishes a legal framework for all activities in space. The Treaty forbids any government from claiming the Moon or any other celestial body under its own sovereignty. However, this does not explicitly prohibit a corporation or even a nation from mining or using resources from space for a profit. Nonetheless, the Treaty states that nations can “use” outer space but “for the benefit of mankind” and “that states shall avoid harmful contamination of space.” Both of these statements conflict with any private company or individual nation setting up a mining operation on any celestial body.
Why are metals irreplaceable?
While some elements can be substituted for others, many metals are effectively irreplaceable because of their unique properties. While we may find new sources of these metals, it will likely be harder to extract them, leading to increased costs and a need for cheaper alternative sources.
Is it possible to mine asteroid?
Given all the complexities and obstacles described above, asteroid mining is not currently technologically or economically feasible. Asteroid mining will only become a reality if 1. mining for materials on asteroids becomes cheaper than mining them on Earth, or 2. mining and processing materials in space for use in space becomes cheaper than launching and sending spacecraft with those materials from Earth. Given humanity’s exponential increase in raw material consumption and entrepreneurs’ desires to push the limits of spaceflight, this scenario could become a reality sooner than we think.

How to extract water from meteorites?
For asteroids such as carbonaceous chondrites that contain hydrated minerals, water and other volatiles can be extracted simply by heating. A water extraction test in 2016 by Honeybee Robotics used asteroid regolith simulant developed by Deep Space Industries and the University of Central Florida to match the bulk mineralogy of a particular carbonaceous meteorite. Although the simulant was physically dry (i.e., it contained no water molecules adsorbed in the matrix of the rocky material), heating to about 510 °C released hydroxyl, which came out as substantial amounts of water vapor from the molecular structure of phyllosilicate clays and sulphur compounds. The vapor was condensed into liquid water filling the collection containers, demonstrating the feasibility of mining water from certain classes of physically dry asteroids.
How can asteroid mining be profitable?
Other studies suggest large profit by using solar power. Potential markets for materials can be identified and profit generated if extraction cost is brought down. For example, the delivery of multiple tonnes of water to low Earth orbit for rocket fuel preparation for space tourism could generate a significant profit if space tourism itself proves profitable.
What metals are mined from the Earth's core?
This left the crust depleted of such valuable elements until a rain of asteroid impacts re-infused the depleted crust with metals like gold, cobalt, iron, manganese, molybdenum, nickel, osmium, palladium, platinum, rhenium, rhodium, ruthenium and tungsten (some flow from core to surface does occur, e.g. at the Bushveld Igneous Complex, a famously rich source of platinum-group metals). Today, these metals are mined from Earth's crust, and they are essential for economic and technological progress. Hence, the geologic history of Earth may very well set the stage for a future of asteroid mining.
What are the challenges of mining asteroid?
Notable asteroid mining challenges include the high cost of spaceflight, unreliable identification of asteroids which are suitable for mining, and the challenges of extracting usable material in a space environment.
How is nickel extracted from an asteroid?
The nickel and iron of an iron rich asteroid could be extracted by the Mond process. This involves passing carbon monoxide over the asteroid at a temperature between 50 and 60 °C for nickel, higher for iron, and with high pressures and enclosed in materials that are resistant to the corrosive carbonyls.
Why are iron meteorites linked to M-type asteroids?
Iron meteorites have been linked to M-type asteroids because both have similar spectral characteristics in the visible and near-infrared. Iron meteorites are thought to be the fragments of the cores of larger ancient asteroids that have been shattered by impacts.
What is the metal used in meteorites?
For usage of the metal of iron meteorites, see Meteoric iron.
What are iron meteorites?
Iron meteorites, also known as siderites, or ferrous meteorites, are a type of meteorites that consist overwhelmingly of an iron–nickel alloy known as meteoric iron that usually consists of two mineral phases: kamacite and taenite. Iron meteorites originate from cores of planetesimals.
What is the chemical classification scheme for meteorites?
A newer chemical classification scheme based on the proportions of the trace elements Ga, Ge and Ir separates the iron meteorites into classes corresponding to distinct asteroid parent bodies. This classification is based on diagrams that plot nickel content against different trace elements (e.g. Ga, Ge and Ir). The different iron meteorite groups appear as data point clusters.
What are the major minerals in meteorites?
The overwhelming bulk of these meteorites consists of the FeNi-alloys kamacite and taenite. Minor minerals, when occurring, often form rounded nodules of troilite or graphite, surrounded by schreibersite and cohenite. Schreibersite and troilite also occur as plate shaped inclusions, which show up on cut surfaces as cm-long and mm-thick lamellae. The troilite plates are called Reichenbach lamellae.
How many groups of meteorites were there in 2006?
In 2006 iron meteorites were classified into 13 groups (one for uncategorized irons):

Because they are also denser than stony meteorites, iron meteorites also account for almost 90% of the mass of all known meteorites, about 500 tons.
What is the composition of an asteroid?
Composition. An asteroid’s composition is mainly determined by how close it is to the Sun. The asteroids that are nearest the Sun are mostly made of carbon, with smaller amounts of nitrogen, hydrogen and oxygen, while the ones further away are made up of silicate rock. Silicates are very common on Earth and in the Solar System.
What are the minerals found on asteroid?

The metallic asteroids are composed of up to 80% iron and 20% a mixture of nickel, iridium, palladium, platinum, gold, magnesium and other precious metals such as osmium, ...
How did asteroids change over time?
But asteroids may have changed over time. It is also thought that chemical reactions over the millennia or more recent impacts they may have endured also effects the composition of asteroids. Some experienced high temperatures after they formed and partly melted, with iron sinking to the center and forcing basaltic (volcanic) lava to the surface. Only one such asteroid, Vesta, is known to have this type of surface.
