space mining refers to the planned extraction of mineral content from asteroids, comets, planets and other celestial bodies. Astronomers and scientists have confirmed that a single asteroid can actually hold a large amount of metals and minerals, which may be equivalent to the total monetary value of billions of dollars. This fact has aroused a lot of interest, including scientists and businessmen. If asteroids hold such large deposits of valuable minerals, energy, investment in mining these minerals from small planets may prove to be very profitable< However, an asteroid with a diameter of at least 1km has been found, which may hold billions of tons of materials, including precious metals and ores Space mining, therefore, can also be a good way to solve the growing scarcity of minerals on the earth and problems brought about by solid mining< According to scientists, an asteroid is actually a piece or a large piece of destroyed planet. As of today, it is an established fact that thousands of asteroids continue to form clusters between Mars and Jupiter. The resulting asteroids are called asteroid belts. In addition to meteorites found in the asteroid belt, there are many other asteroids close to the earth's orbit
asteroids can be classified according to their own properties and contents. One is the so-called C-type asteroid. In this category, asteroids must be composed of similar materials, that is, the sun, but it does not have volatile substances, that is, the sun. More or less 75% of all known asteroids fall into this category
the other is the so-called S-type asteroid. Asteroids have deposits of iron, nickel and magnesium in this category This includes about 17% of all known asteroids
other types of asteroids are called M-type asteroids. Asteroids of this type are most likely to contain nickel and iron, and they make up a small part of the entire known asteroid population< Do you have any excavation work in the space
there are two possible ways to make asteroids (later, other objects) recoverable One of the ways is to bring the two people back to earth for mining and processing. In this way, it can be used in normal mining process
another possible way to mine asteroids is to process all the ore on site and then return the processed or refined material to earth. If the extraction of the scene is employment, all the necessary facilities and human power will be brought to justice. This will require additional fuel for travel, outer space and resources to power mining facilities, residential quarters and other things crew needs
. Lightweight materials will be used to support the excavation at the site, so as to save rocket fuel for travel expenses. The asteroid is a small one. It has been suggested that the rocket should be able to use any possible fuel to find the asteroid and return to earth for the journey. One possible source of fuel is water< Whether space mining can be realized or not is the material basis for human survival and development. It's hard to imagine where we would come from ceramics, plastics, steel and oil without mineral resources. However, the depletion of the earth's resources has worsened our environment. And the development of aerospace has opened up a way for us to mine space
it has long been known that there are many useful minerals in the universe, and the first metal iron used by human beings is the iron meteorite from the sky. In ancient Mesopotamia, iron was called "fire falling from the sky", while the Egyptians called iron "stone in the sky". However, it is obviously impossible to wait for God's gift. The limited small pieces of meteorite are just a drop in the bucket, which is far from what we need
we also know that asteroids in the solar system are the matrix of many meteorites. Among them, there are about 1000-2000 indivials whose diameter is more than 100 meters in the small objects called "Apollo" which are closer to the earth. Some of them are composed of almost pure metals. Besides iron, some of them are rich in nickel. The highest nickel content can reach 65%. We should know that the most abundant nickel ore on the earth only contains 2% - 3% nickel; Others contain cobalt, chromium, manganese, aluminum, gold, platinum and other precious metals. For example, the asteroid No. 1986da discovered in 1986 is a small object less than 2000 meters in diameter, but it contains about 10000 tons of gold, 100000 tons of platinum, 1 billion tons of nickel and 10 billion tons of iron. What's more exciting is that although the asteroid is a little farther away from us than the moon, it is much closer than other planets. Obviously, it will be the preferred target of space mining in the future
the problem is how to exploit these rich space minerals. Generally, two methods can be considered: one is to directly send robots to the small objects to be mined, and where to mine them, and then refine them in space factories and use them in space manufacturing, or transport the minerals back to earth by space shuttle or ladder
another method is to change the orbit of the original small object, make it fly to the earth, and give appropriate speed to land at the designated place. It is not difficult for a small celestial body to change its orbit. What is difficult is how to control its landing speed and location so that when it falls, it will not cause a big collision and disaster.

2. ... I don't know how to dig. First go to the tool vendor to buy a stone hoe, then go to the town mine. When I get to the mine, I point the hoe in my backpack, and then point the ground. After a period of time, there is a circle on the ground. Move the mouse there to see if it's yours. If it's yours, click the left mouse button and pick it up.
3. Did you buy BB's skill book? Is there a drawing hoe in its bag? 1 and skills with stone, level 2 is iron and stone can be
if it's all right, then take it to the mine. The guy's work depends on the training degree. If he's low, he'll walk around. He only digs in a long time. It's all done by himself. You can do it by yourself< PS: you can train it when you have nothing to do. If you have a high degree of training, you will be diligent!

4. sure. Just stay and become a citizen. However, when advanced tools are needed later in mining, there are also requirements for the grade. Let's practice
5. Take a long-distance bus to Shanghai South Railway Station. If you take a speedboat, go down to Nanpu Bridge and buy it. Take a slow boat to No.59 Jinling east road or Wusong passenger terminal in downtown area. The above items are sold three days in advance

9. Cloud computing is a kind of service; Virtualization and distributed system are the key technologies to realize cloud computing< At present, virtualization mainly uses two core technologies: server virtualization and application virtualization
at present, distributed system mainly uses two core technologies: distributed storage and distributed computing
cloud computing can be understood as a rental service, that is, you can understand nothing about the internal principles of IT system, and you don't need to buy it, But at any time, we can use public IT resources to serve ourselves, such as QQ, such as 163 mailbox
I think the best definition of virtualization technology is to make the physical topology of the IT system independent of the logical topology, that is, decoupling
let's take VMware as an example for the moment
in order to achieve topology decoupling, The first thing it does is to enable a machine to run multiple operating systems at the same time, that is, virtual machines. Virtual machines can also be transferred back and forth between physical machines, which is highly available. In this way, our operating system is completely liberated from physical machines. You can put the same virtual machine on other physical machines at any time, realizing efficient resource utilization of hardware, And the system is highly flexible, which relieves a lot of manual labor and facilitates the management of large-scale systems. This is called vSphere
it's not good to separate the optical system. Sometimes you need to access the virtual machine system in various ways, so you will use remote desktop and other ways to access these background virtual machines, which is called application virtualization
of course, network virtualization, storage virtualization and other virtualization technologies are growing slowly. However, compared with the former two technologies, whether they are commercial or open source, they are not mature enough to be discussed
I think a more appropriate definition of distributed system is to use all it resources as a whole, rather than looking at a machine or a system independently, that is, resource pool
let's take open source Hadoop as an example for the moment
in order to turn it resources into a whole, the first thing it needs to do is to open a huge file in multiple places, You can use a lot of ordinary computers connected to the network to store this huge file, so that even many machines with very small hard disks can be connected together as a large storage space, which is called distributed storage (HDFS)
optical files can't be stored together, so computing power should also be combined, so it has to meet the requirement that a task is distributed to multiple physical machines for processing. In this way, even if a bunch of old computers are connected together in this way, as long as there are enough, they can also be used as supercomputers, which makes distributed computing (maprec)
of course, other technologies such as HBase are also graally maturing. Generally speaking, they are all technologies needed to build a huge resource pool
from this, we can see that virtualization is mainly to break up the big pieces into small pieces, and distributed system is mainly to combine the small pieces into large pieces. After such crushing and recombining, it resources become a very flexible system. On the basis of these basic technologies, cloud computing service mode can be realized through certain scheling and operation
therefore, this is not conceptual hype~
