Nok en diff bar it gave av magasinet. Bra jobba!
Jeg melder meg som deltager på «Vil du bli trillionær?»
Hei @Susanne,
På med romdrakta og frem med pressluftborret. ;)

Spennende tider i møte når det kommer til utforsking av verdensrommet ser det ut til. Med tanke på hvor mye vi mishandler den planeten vi har er det absolutt ikke dumt å finne ressurser et annet sted. Blir spennende å se hvor langt unna vi er punktet å gjøre forsøk på å kolonisere andre planeter.
Hei @k3nb0b
Vi er nok ikke i stand til å kolonisere noe som helst på riktig så lenge. Men vi må begynne ett sted. Og i disse dager går ting i riktig retning igjen, starten på dette århundre har hatt mange tilbakeslag når det kommer til utforskinin av verdensrommet.

Gold in asteroids
Asteroids, like all rocky planets are formed from the remains of heavy and solid elements present on site during the formation of the solar system. Gold is not more abundant than on Earth: gold is more abundant than in the earth's crust alone. In addition, gold is found on the surface as well as inside, because of the differentiation that did not occur.
This is because it is on the surface that it is much more profitable and convenient to go looking for it there! Indeed, send a space probe on an asteroid, we know how to do it and it's only a problem of cost. On the other hand, dig a hole to the center of the Earth, we do not know how to do it and it is not possible technically (we have to cross the rocky cliff at 5000 ° C and then dig into a metal core, all under pressure and unimaginable constraints).
This is why we talk (often hyperbolic still) of asteroids "filled with gold": gold is simply more accessible than on Earth and not necessarily in larger quantities.
To go further, know that all the treasures or mineral resources that are planned to mine are not gold or silver: some comets are filled with ice water. Now water, if electrolysis, we end up with hydrogen and oxygen, which is nothing other than fuel for rocket. It is therefore possible to make "gas stations" for space expeditions: it would be much more profitable there than taking fuel on Earth (which is more abundant, but weighs heavily on takeoff).
Without forgetting the solar energy: on Earth, a good part of the luminous flux received from the Sun is directly reflected in the space and another part is diffused or absorbed by the atmosphere. Space is even more conducive to the exploitation of solar energy than it is on Earth: it is not for nothing that the International Space Station (ISS), the Hubble Space Telescope or various other probes or satellites are powered by solar energy.
Finally, other chemical elements are simply absent from the earth's crust because they have flown into the inter-planetary space. This is the case of helium-3. Because of the volcanism and the modification of the continental rocks, all the helium-3 that the Earth had is no longer there today. The moon, on the other hand, has significant helium-3 resources, trapped in the rock for billions of years. This helium is a possible nuclear fuel for fusion power plants, which are much cleaner than current plants.
Hi @lovework
Thanks for bringing additional information on this topic.
Now, I wonder what the price of on gallon of water will be on the first interplanetary "gas-station" :)
As of today is't about $1700/kg with the new Falcon Heavy.
Cheers,
@Onebitnews
1,700 $ / kg !! wow it's almost the triple of the price of silver :)
Yepp, I don't know the price of heroine... But it't "up there" I guess.
Cheers, @Onebitnews
Agree, but how are we going to drill in space?
As in science fiction movies: we send a machine that will dock with the asteroid by harpooning for example. Then all the prospecting material is brought down. Then, either refining on site or bringing the ore back for processing on land.
Of course, we will attack, preferably, the asteroids that pass closest to the earth. There are about 15,000, so there is a lot of choice.
Hi @redouanemez
Good question, it is possible to scout and find the right one to prospect from earth using telescopes and spectroscopy.
Cheers, @Onebitnews
Yes you are right !
Based on physico-chemical measurements of the Mercury planet crust carried out by the NASA Messenger probe between 2011 and 2015, as well as on laboratory experiments at extreme temperatures aimed at restoring the conditions observed during crystallization. magmas, a team of geologists has managed to identify the mineralogy of the planet closest to the Sun. It is the University of Liege, in Belgium, which announced this in a statement published this Monday, December 19th, 2016.
In an experimental petrology laboratory set up at the University of Liège, Olivier Namur and Bernard Charlier, researchers at the F.R.S.-FNRS (Scientific Research Fund), succeeded in reconstituting samples of Mercury magmas. The planet, the least massive of the Solar System is one of the four telluric planets (mainly composed of rocks and metals) of our solar system with Venus, Earth and Mars.
In their study, published in the journal Nature Geoscience, the researchers explain having defined different regions in the northern hemisphere of Mercury, each characterized by a specific mineralogy. According to the University of Liège, this major discovery is the link between the age of these regions and the mineralogy of the lavas on their surface, which demonstrates the major role of the thermal evolution of Mercury on its volcanic history. Thus, their conclusions allow to better understand the mineralogy of Mercury and more generally the evolution of this planet.
On Mercury, the crust is of magmatic origin, resulting from the flow of lavas from the mantle between 4.2 and 3.5 billion years ago. This activity then experienced an early interruption 3.5 billion years ago, making Mercury the telluric planet that has cooled most rapidly in our Solar System.
In the same frame, the astronomers have detected the presence of water molecules in the atmosphere of the exoplanet 51 Pegasi b, a hot Jupiter located about 50 light-years from Earth in the constellation Pegasus.
Related to the history of commercial spacecraft, the Tianzhou-1 ("Heavenly Ship") vessel was propelled on april 2017 from the center of Hainan, an island in southern China, by a Long March 7 rocket and began its approach to the space laboratory Tiangong-2 ("Heavenly Palace").
This laboratory is supposed to pave the way for the planned deployment of an inhabited space station in 2022, when the International Space Station (ISS) has ceased to function. The cargo ship represents a "crucial step" in the construction of this Chinese station, said the official agency China New.
the information provided above is taken from some websites related to space and scientific research.
Due to the need for conquest of space for the search for vital needs, the spacecrafts of the future will be designed as research laboratories.
We will see that liquid water is probably present in the Galaxy, perhaps even more than our solar system suggests with planets like Mars, the object of all fantasies since the formulation of the hypothesis of life on Earth March. On the other hand, if the presence of liquid water is a necessary condition for the appearance of life, it certainly does not appear to be a sufficient condition.
It must already be remembered that only liquid water has an interest: water ice or water vapor have no particular value for life. In fact, the interest of liquid water lies in its ability to promote chemical reactions.
Living beings consist of an orderly arrangement of incredibly complex molecules: to create such structures, simple organic molecules had to react chemically together, in order to grow and transform. So it took a very special environment to allow these reactions to happen.
Are all liquids the same from the point of view of chemistry? Far from there ! Suppose we want to mix two species together in a liquid such as oil, to make them react. The heavier species tends to settle at the bottom, while the lightest tends to float. Finally, the two species remain separated and can not react effectively.
Now mix these two species in water. The molecule of water has an interesting property: it has a positively charged side, and the other negatively charged. It is said to be a "polar" molecule.
Thanks to the electrostatic attraction due to these charges, it tends to "stick" to many other species.
Thus, if we put alcohol in water, the water molecules will be eager to surround each molecule of ethanol: alcohol is dissolved in water. Although it is lighter than water, the alcohol does not float above it: a unique mixture of water and ethanol appears, each molecule of ethanol being closely "glued" to the water molecules. If this were not the case, the first to open a bottle of wine would drink pure alcohol, while the following would be satisfied with the juice of grapes below
Hi @agdali
You are right, life boils down to chemistry in the end, or beginning... Depending on how you see it.
According to Jeremy England the origin and subsequent evolution of life follow from the fundamental laws of nature and “should be as unsurprising as rocks rolling downhill.”

Thanks for the additional information to our article.

You welcom
Thank you @onebitnews
I believe asteroid mining will be huge, your thoughts on refueling stations and being able to gather water without having to carry it is definitely something that needs to be watched!
I think also in the future there will be many space colonies and construction companies that will prosper.
Food production should also be right up there on the top of the list.
Hi @tbnfl4sun
You are right, there is a huge amount of stuff that we humans need to bring with us if we are to venture further into space than the ISS. So hopefully it is going to be good times for all sorts of contractors over the next years.
Cheer, @Onebitnews
According to the UN and as written on the comment written by @mahassan companies don't own the asteroid and all the extra-atmospheric objects. This does not allow them to exploit them and gain profit.
Hi @Suoada,
Companies can mine for resources, but not claim ownership to different asteroids.
Space is reserved for the benefit and is the province of all mankind.
Cheers, @Onebitnews
Yes @tbnfl4sun what you say is totally true unfortunately every scientific discovery becomes after an opportunity for commercial exploitations and so it is normal to plan colonies also in space.
Wow, dette var interessant lesning. Har egentlig ikke tenkt så mye over alle mulighetene det er ved gruvedrift i rommet, men etter å ha sovet på det så gir det jo mening at det er det som er fremtiden. Jeg tror neste kapittel innenfor kommersiell romfart er kortere private reiser, la oss kalle det 'charterreiser i rommet'. Privat aktør med romstasjon ala ISS, hvor romturister kan reise for å få smaken av rommet. Det er for meg et logisk steg på veien mot planeter som Mars.
Kommersiell gruvedrift i verdensrommet vil komme. Tror det eneste som trengs er at man kommer opp med en måte man kan utnytte ressursene der de utvinnes. 3D printing vil da være avgjørende for å bygge ting i verdensrommet. Blir for omfattende med store fabrikker.
Holder på tiden på å lese boka The Martian. Har ikke sett filmen, men boka er veldig bra. Her får man et innblikk i hvordan luftrensning, vanngjenvinning, dyrking av mat etc kan foregå. I tillegg er det en veldig bra og spennende historie.
Anbefales på det sterkeste!
Hei @idigit,
Står herved på leselista ;)
Takk for tipset!

Anbefalar alle som har muligheit til å sjå National Geographic serien MARS. Veldig god og realistisk serie om dei første menneska som reiser til, nettopp, Mars.
Personleg tykkjer eg utviklinga i romfarten går seint. Kanskje vi må få i gang ein kald krig att, slik at vi får eit nytt kappløp. På den andre sida har vi jo ikkje utforska alt av vår eigen planet enda. Vi har ikkje kartlagt havbotn feks.
Orker ikke å leve med duck and cover kampanjer bare for at noen skal få dra til Mars (Og jeg ikke får bli med)
Enig i at 2000 tallet ikke har innfridd og du er nok inne på noe. I fredstid er romfart en utgift.

2016 saw the launch of the Osiris-Rex spacecraft with a bold mission: to meet an asteroid, collect samples and bring them back to Earth. A 7-year expedition involving Canadian researchers.
The asteroid in question is called Bennu. At a height of 500 meters - about the size of the Empire State Building in New York - it revolves around the Sun and passes near our planet. Bennu is one of the asteroids known as NEOs, that is to say, who evolve near the Earth. Like others, it is part of the asteroid belt, located between Mars and Jupiter.
Bennu, named after an Egyptian deity, has the advantage of being located at a reasonable distance from the Earth, which allows to go there in a relatively short time. In this case, Osiris-Rex will take a little less than two years to get to the asteroid.
This mission could even pave the way for the possibility of deflecting an asteroid threatening the Earth. Bennu himself would represent a certain threat to the Earth, but imprecise and expected in a few hundred years.
The collection of samples on Bennu will be done in a very special way: the probe will approach the asteroid and take its samples for just five seconds.
But what will they look for up there that we do not find here below? First, precious metals like platinum. Metals whose needs, especially for electronic equipment, are more and more important and are very rare on Earth. For example, it is estimated that a 500-meter asteroid could contain more platinum than has ever been extracted from the earth's subsoil. What excite some lusts.
The second precious element in space is water. It may seem paradoxical, but water in space is a way to get oxygen and hydrogen ... fuel for rockets. Today, sending fuel into orbit is prohibitively expensive. If it could be manufactured directly on site, it would provide the opportunity to refuel without the expensive need to escape the gravitational pull.
