6 Cryptocurrencies You Should Know About (and None of Them Are … – Entrepreneur

Posted: April 21, 2017 at 2:05 am

In the 21st century, money is no longer limited to bills, coins and credit cards. In fact, some money is truly international -- not owned by any particular government -- and regulated by the people instead of a central entity. It also exists wholly on the internet. This type of money is called cryptocurrency.

You may have heard of or even used Bitcoin when it first became popular several years ago, but where Bitcoin used to rule, other cryptocurrencies are now being used to pay back family members for lunch, charge customers for products and services and make other everyday transactions. As an entrepreneur, its important to keep an eye on the most commonly-used cryptocurrencies. Here are six I think you should know about.

Rather than competing with Bitcoin like many other cryptocurrencies, Ethereum complements it; while the Bitcoin blockchain network tracks ownership of its own currency, the Ethereum blockchain runs programming codes for its users applications. People use Ethereum to create custom (but trustworthy) crowdfunding platforms, autonomous online organizations and even their own cryptocurrencies. Because these applications are decentralized, they can only be built in the Ethereum network.

Though Ether, the network's money,wasnt made to be used for everyday payments, anything of value can be traded for products and services; as a result, many developers use it to pay for each others help in building applications.

However, most online stores that accept cryptocurrency do not take Ether.

If Bitcoin were gold, Litecoin would be silver. Litecoin works just like its more popular counterpart, but its worth a little less -- there are 21 million total Bitcoin in existence and 84 million Litecoin. Litecoin are easier to mine and quicker to move from person to person due to its faster block generation. It is perhaps the least intimidating cryptocurrency for those who are new to exchanging money online: Litecoins wallet can be downloaded fromthe official Litecoin website, and its fully encrypted to prevent accidental spending and computer viruses. This is a super simple network for those who need to move smaller amounts of money fast.

While other cryptocurrencies avoid banks, Ripple embraces them. In fact, Ripple was made for banks, as it allows them to make faster, low-cost, on-demand global payments of any size. Traditional cross-border transactions require banks to go through an intermediary (or often several), which delays completion. Ripple offers a faster and more direct alternative. When a bank customer in the US wants to send a payment to a different bank customer in China, for example, Ripple immediately queries both banks for their transaction fees and makes the transfer in a matter of minutes. It even updates both customers ledgers right away so they can view their balances following the transaction. This unique cryptocurrency enables banks to offer new and improved payment products, and it simplifies regular transactions for consumers around the world.

Though Dash can be used for transactions between consumers, it was made for shopping. Think of Dash as a replacement for PayPal. Many merchants accept Dash just as they do USD, but the transaction is faster -- you dont have to wait a day or two to see the payment charge to your account. Like any other cryptocurrency, you can buy Dash using government-regulated currency and keep it in a designated Dash wallet until youre ready to spend it at a compatible merchant. You may even consider adding your own business to the merchant map!

If you want to maximize your confidentiality, this cryptocurrency is for you. Zcash has been dubbed the first zero-knowledge cryptocurrency with its ability to shield the identities of all senders, recipients and values. Each transaction is fully encrypted, so users can enjoy the advantages of a public blockchain without offering up private information. Many view Zcash as a more confidential version of Bitcoin.

Monero is another excellent cryptocurrency option for those concerned about their privacy. This currency was designed to give individual users full control over their money; with Monero, you are your own bank. Transactions are selectively transparent, meaning you decide who can and cant see where your money is going. Crises faced by banks and governments wont affect your assets or compromise confidential information. Finally, like many cryptocurrencies, Monero is decentralized and community-built -- over thirty developers have directly contributed to Monero so far.

If your business doesnt use any of these cryptocurrencies already, you may want to start incorporating them soon. When it comes to online financial transactions, cryptocurrencies like the ones above have quickly started to give PayPal, Stripe and other payment systems a run for their money.

Cryptocurrency transactions arent validated by a central entity, meaning there are no bank or platform fees associated with payments -- just optional, minute fees (one percent or less) that speed up the transaction. You also dont have to wait nearly as long to receive cryptocurrency as you may with traditional money.

Again, a cryptocurrency'smost important feature might be that it'struly international; no particular government owns or regulates it. This means there are no fees for payments that cross borders, and the transaction works the same no matter where you or the other party are located.

The only major disadvantage to cryptocurrency is the need to sell it for USD (or any other government currency). However, this process closely imitates the way youd transfer PayPal funds to your checking account.

Moradeyo: We Want to Close the Knowledge Gap on Crypto Currency – THISDAY Newspapers

Posted: at 2:05 am

In Asia, Europe and the Americas, Cryptocurrency trading has become a way of life, but that is not the case in Nigeria and other African countries. In this interview, the Chief Executive and Principal Consultant,Crypto Plus Certified, Mr. Peter Ayoade Moradeyo tellsNdubuisi Francisthat his company is poised to close the knowledge gap with the ultimate goal of enlisting Nigeria on the global cryptocurrency exchange. Excerpts:

What is a good way to concisely explain Bitcoin, block chain and crypto currencies?

The success story of Crypto currency dates back to 2009, during the financial breakout, when Bitcoin was formed on blockchain technology. Bitcoin was first introduced in Asian countries and gradually to Europe, US etc. It is needful to clarify however, that the blockchain technology is not the same thing as Bitcoin; the relationship between them is only that Bitcoin is deployed on the blockchain technology. Interestingly, Bitcoin seems to be more popular today than the platform on which it stands. Now, there are two things which distinguish Crypto currency from the normal currencies. The first is that it is finite. It has a fixed number that can be taken off and immediately that happens, its value shoots up and we all know that anything that can finish naturally increases in value as it is being taken up. So, as the world gradually adopts cryptocurrency, the available number reduces and value automatically drives upwards, causing it to grow dynamically in value. That explains why Bitcoin has been able to grow like that since 2009. The second thing is that cryptocurrency has intrinsic value or what some call store of value. Let me explain it this way: each copy of a coin is an address, a location on the blockchain. When one address belongs to a person, that address cannot belong to another person in any part of the world. This is unlike the fiat counterpart where any money reading on a persons bank account means that the bank owes the account holder to the tune of the said amount, but not necessarily that that money is the account holders to cash at any time. This is why sometimes the banks would tell an account holder that they do not have enough cash to complete a transaction. The case of the blockchain is different because the value is intrinsic and better preserved.

What is the function of CryptoPlus Certified?

Since 2009, Bitcoin and several other alt coins have been coming up. Alt coins are referred to as alternative coins to Bitcoin which is the first and most popular of them all. At a point, we realised there was an opportunity where Bitcoin and other coins can relate in value;there is value relativity between them. So, we started by trading Cryptocurrency. I can recall that sometime in 2015, there was an upsurge of certain Ponzis in Nigeria. Nigerians sustained the following of Ponzis until it became almost endemic. Unfortunately, very few Nigerians knew about the very essence of the medium of transfer which Bitcoin was during the transaction of these Ponzis. Bitcoin was only used because it did not need a third party like banks to facilitate a transaction between the Ponzis and their victims. So, the Ponzis took advantage of their patronage, cashing in on the anonymity of transaction which was part of the features of cryptocurrency. What was supposed to have been an advantage became a disadvantage because of the ignorance of Nigerians. Someone needed to educate Nigerians appropriately as to what cryptocurrency really meant and what disruption it was meant to address. So, we now came up because before now, we had a deep background on its trading. We decided to reappraise the image of Cryptocurrency as it were in Nigeria. Also, at several conferences we have been all over the world, we realised that Africans are non-existent on several cryptocurrency trading platforms. Just like we have the Nigerian Stock Exchange with several companies trading on its platform, there are also several participating bodies that trade value among us. The sad thing here is that Africans are non-existent on any Cryptocurrency exchange whether in US, Asia or Europe. This is also true when one considers Cryptocurrency graph. The Asians are up there; Europe and America are there too, but Africa is non- existent. Our function at Crypto Plus Certified is basically to close the knowledge gap so that people can take advantage available and then Nigeria can be enlisted on what we call the global Cryptocurrency exchange. We trace the current state of Crypto currency trading to slowness of adoption. The federal government is yet to adopt a framework for the implementation of blockchain that can give rise to participation. Several countries have done that but for some reasons it has not happened in Nigeria.

You have a dream to raise and establish 1,000 Nigerians on the Poloniex Exchange. What is the implementation plan put in place to achieve this and why the choice of Lagos, Abuja and Port Harcourt?

We need to make it clear that Nigeria is a country with many opportunities. We also need to state that Bitcoin came into Nigeria with a wrongly perceived image, and on the wrong platform. So, our first goal is to take the responsibility to repair that image, and then reappraise the benefits and enlist Nigeria as a participator in the normal trading of Cryptocurrency. In order to achieve that, we launched what we called, Dream 1000. It is all about trading on Poloniex which is the largest Crypto exchange in America and we are currently working with them on releasing a mobile platform strictly for Nigerians and it will work as an arbitrage with our own exchange which will come from Germany. We want to work as an arbitrage so that they will trade on our own platform via the mobile interface. Nigerians can be taught on how to trade this currency easily, and our strategy is very unique because the mobile application is actually enhanced to be able to reduce all the variables of trading system. Since we launched the Dream 1000 recently in Lagos, we have had some of our students who were able to distinguish themselves with the level of knowledge we passed to them and they are going to show Nigerians that we are serious about what we are here to do. We have this oncyptopluscertified.org.

How has the response been like?

I grew up in Nigeria before I decided to relate with other countries for business reasons. One thing I know about Nigerians is that they respond to results. So, the first thing we want to identify is, we want to be able to have people who have had results and that is why all the events we have done, we have been showcasing people that distinguished themselves, those that we gave the knowledge and they applied it and got results. We want to be inspired by results and not just belief.

Can Bitcoin be regulated? What about Bitcoin and taxes?

Those conversant with information coming out of cryptopluscertified would have noticed that Nigeria is currently on a discourse on how to regulate Cryptocurrency trading based on several frameworks. I have several write ups regarding this. Cryptocurrency trading as it were is decentralised and this is why the banking system cannot operate it. It is decentralised because of its nature. For instance, Bitcoin as it were, does not have a management interface and that is why the regulation has not been somewhat forthcoming. But it is found to be very secured and has ability to store values. That has been the reason for all the enquiries on how do we have a framework for a kind of currency that has thus kind of features? Sometimes, it takes time, but individuals are working and several people have stored values on it and exchanged it with another. The US is an example where Poloniex is operating. So looking at it more objectively, the regulatory framework and the operational climate go hand in hand but they can be mutually exclusive.

Bringing it to a laymans understanding, what are the advantages of Bitcoin and how does Bitcoin work?

In a laymans way, I would like to use the similitude of changing one currency to another, for instance. If you have some Naira notes and you want to change to Dollar, knowing the exchange rate that relates one to the other will be very helpful. Now to a layman if I bring my Naira and want to buy a Dollar, I will change the Naira to a Dollar based on the foreign exchange rate agreed between the person selling the Dollar and myself. Now imagine where you have the Bureau de Change in the middle and you have the buyer, that is, the demand, on one side and the supplier on the other side; that is the way it works. The person at the middle collects commission from two persons. The buyer sells at a price based on demand and supply. So, if the demand is higher than supply, the price is likely to go up. If Im able to read that the demand and price for a thing I bought and own have gone up and I sell it, now the difference between what I bought and what I am selling now that the price has gone up is my own profit. That is the basic analysis of how it works.

Demand for Cryptocurrencywhat are your training modules like? The fee, process and duration?

Training is 30 days and we have a huge demand for it and because of this, we have set up world class training hubs in the three geopolitical zones Lagos, Abuja and Port Harcourt. So, demand is already there. We have a structure that accommodates different levels of trading the strategic portfolio building and robotics. Our modules cover; Introduction to Cryptocurrency Trading CPC 101 Cryptocurrency Masterclass Advanced Trading CPC 102 Trading Engaging Robotics CPC 103 People are already aware of what Cryptocurrency is; it will be wrong for us to say that people are not aware of it. The only thing is that there is a knowledge gap on how to use it and take advantage of the value in it, and that is what we are trying to close up.

Is there any risk attached to Cryptocurrency Is Bitcoin legal? And how secure is Bitcoin?

The idea of trading Cryptocurrency and the national legal framework is mutually exclusive. Trading on Cryptocurrency can be done when someone knows how to handle it. The reason for the legal framework is to protect the participators because when there is no third party that puts power in the hands of those that know the Whats and Hows. Bitcoin is safe and this knowledge is out there. You are your own bank. Records are protected by mathematical laws and are irreversible. The Blockchain technology protects its addresses and have histories on an open ledger, and is always available and transparent for anyone to confirm.

Billionaire says he has 10% of his money in Bitcoin, Ether and … – CNNMoney

Posted: at 2:04 am

"Ten percent of my net worth is in this space," Novogratz said at a forum held at the Harvard Business School Club of New York Wednesday. He declined to say exactly how wealthy he is, but he's a former hedge fund manager at Fortress Investment Group and a Goldman Sachs partner who made the Forbes billionaire list in 2008.

It's the "best investment of my life," Novogratz said.

Bitcoin was worth under $500 a year ago. Today the digital currency trades at over $1,200. Back in 2013, Novogratz predicted Bitcoin's value would soar. He remembers people laughing at him at the time.

Since then, Bitcoin's price has been on a wild run. It surged to nearly $1,000 in late 2013 and then fell to under $250 in 2015. It started to fly again last year, around the time of the Brexit vote. It surpassed $1,000 in January of this year again and has kept climbing.

Now Novogratz is saying Bitcoin will go to $2,000.

But he also warned the Harvard Business School Club crowd that there will "likely be a bubble" in digital currencies. The best way to handle it, he argues, is the old Wall Street trick of diversification. Put a little money in a lot of different plays in digital currency.

For example, Novogratz was also an early investor in Ether. It's another digital currency that has quickly emerged as the No. 2 rival to Bitcoin. Novogratz says he bought Ether when it was trading for about $1. Today it's worth over $48.

Novogratz met Vitalik Buterin, the young Russian brainchild behind Ether at a dinner party at a prominent CEO's home. He recalls that Buterin, then 21, showed up late, which struck him as shocking -- and a bit ballsy. He figured it was worth paying attention to Buterin.

Ether is a currency with a "smart contract" function that gives users additional security and abilities to transfer information in addition to monetary value.

We're witnessing the "3rd inning" of this digital asset revolution, Novogratz predicts. He's not exactly sure how it will play out, but he plans to continue investing in digital currencies and Blockchain, the revolutionary technology behind the scenes that makes Bitcoin work.

Blockchain is literally a digital ledger to record and track transactions. What makes it so technologically advanced is that multiple companies or parties can access the Blockchain and see the history of what happened to an asset.

Novogratz has emerged as one of the biggest Wall Street cheerleaders of Blockchain, but his bets haven't always gone so well. He exited Fortress in 2015 after the company shut down his Marco Fund for poor performance. It lost around 20% in its final year after his investments in emerging markets, especially Brazil, tanked.

"We have had an extremely challenging two years, and I do not believe the current environment is conducive to achieving our best results," Novogratz said at the time.

Astronaut, Cosmonaut And Stuffed Dog Arrive At International Space Station – NPR

Posted: at 2:04 am

A Soyuz spacecraft carrying a new crew to the International Space Station, ISS, blasted off Thursday from the Baikonur cosmodrome in Kazakhstan.

In case you ever find yourself hurtling into space, know this: When the little stuffed dog starts to float, that's when you've reached Earth's orbit.

NASA astronaut Jack Fischer and Russian cosmonaut Fyodor Yurchikhin lifted off from Kazakhstan on Thursday, bound for the International Space Station. About nine minutes into their voyage, the stuffed dog leaped into the air, then began to drift at the end of the string around its neck. (The dog is the latest in an adorable tradition of stuffed animals in space.)

There was a rare extra seat in the Soyuz capsule; Reuters reports that Russia is scaling back its space station staffing as it prepares to prepares to send a laboratory to the ISS next year.

It's the fifth mission to the space station for Yurchikhin, but the first for Fischer, who he says there is one aspect of space station life that you can't train for on Earth: using a zero-gravity toilet.

"It's all about suction, it's really difficult," Fischer said in a NASA interview before launch. "You just can't train for that on the ground, so I approach my space-toilet activities with respect, preparation and a healthy dose of sheer terror."

Just six hours after launch, the pair docked at the space station. They were welcomed by Flight Engineers Oleg Novitskiy of Russia and Thomas Pesquet of the European Space Agency, as well as Expedition 51 Commander Peggy Whitson of NASA, who on Monday will break the record for longest time spent in space by a U.S. astronaut. She's due to return to Earth in September.

On Saturday, NASA will livestream video of the Orbital ATK Cygnus cargo spacecraft rendezvous and capture at the International Space Station. The cargo craft took off from Cape Canaveral in Florida on Tuesday.

China Launches Their First Robotic Space Station Resupply Ship – Jalopnik

Posted: at 2:04 am

Earlier today, China took a huge step forward in their quest for a continual human presence in space: they launched Tianzhou-1, an unmanned resupply ship that will dock with their space station, Tiangong-2. Id also like to add that I predicted this would happen back in 2012, when I claimed that their first space station, Tiangong-1, was actually a prototype of a resupply ship. I think I was right!

If youll forgive me, I just want to revel in this sadly rare moment of accuracy with this quote from my 2012 article about Tiangong-1:

So, in a nutshell, heres what the Chinese are doing: theyve outfitted what will become a future cargo vessel with a life support system and supplies, allowing their Shenzou crew to practice orbital docking, some limited space station living, test life support and propulsion systems for both future space stations and on their future station-supporting cargo ship all in one efficient mission. When they build Tiangong 2, theyll already have some experience and a resupply ship. Its pretty clever.

Holy crap, thats pretty much exactly how things have turned out: Tianzhou-1 (the name means heavenly vessel, like the free water bottle youll get when you enter the afterlife) is based directly on the original Tiangong-1 space station, and its now being used to resupply Tiangong-2. Im sure plenty of other observers figured this as well, but just let me have this tiny victory, please.

Really, though, what I think doesnt matter a bit. Whats important here is that an automatic-docking resupply ship is absolutely crucial to long-term habitation in space. The Tianzhou series is basically filling the same role as the Soviet/Russian Progress resupply ships, which have been in continuous use since they resupplied the Salyut 6 space station in 1978, and continue to bring cargo and fuel to the ISS to this day.

Tianzhou-1 is based on Chinas crewed spacecraft, Shenzhou, which is in turn effectively a modernized and enlarged Soviet/Russian Soyuz design. Theres a service module providing propulsion, fuel, and electricity via solar panels, and a cylindrical cargo module, which has a pressurized section and can have an unpressurized section as well, usually with fuel tanks to refuel the orbiting station.

This mission will mostly focus on having Tianzhou-1 dock, transfer fuel, and undock from Tiangong-2, multiple times. The main goals of the mission will be to test the automatic docking and refueling procedures.

Its not clear if Tiangzhou-1 has any cargo in its pressurized compartment that will be used on the space station by later Taikonauts when they return to Tiangong-2. Personally, Im skeptical it has any actual cargo, because Im not certain theres any way to transfer that cargo to the station.

In fact, I think that with the current setup of Tiangong-2, there is no way at all to transfer cargo, because Tiangong-2 has only one docking port. The Soviets didnt launch any unmanned cargo ships to their space stations until they had a station with multiple docking ports, Salyut 6, which had two, one at each end.

With at least two ports, one can have a crewed ship docked, leaving the other free for a cargo craft. When the cargo craft is docked, the crew can unload the supplies and equipment from the pressurized cargo compartment. Theres no way to do that now with Tiangong-2, unless they were to leave some poor, lonely sap in the station without a Shenzou return spaceship, which Im pretty sure theyd never do.

So, if I may undertake a new prediction here: this may be the only time well see a Tianzhou cargo ship dock with Tiangong-2. The cargo ships will be used much more extensively when the Chinese launch Tiangong-3 in 2022 or so, which will be a space station module very similar to the old Soviet/Russian Mir core module, and will contain multiple docking ports.

Once that happens, well have two continuously-occupied space stations in Earth orbit, and thats when things should get really fun.

Crystals grown aboard space station provide radiation detecting … – Phys.Org

Posted: at 2:04 am

The SUBSA Furnace and Inserts investigation includes modernized data acquisition, high definition video and communication interfaces. Credit: NASA

Research into crystal growth in microgravity was one of the earliest investigations conducted aboard the International Space Station and is continued to this day. The unique microgravity environment of space provides an ideal setting for producing crystals that are more perfect than their terrestrial-grown counterparts. The Crystal Growth of Cs2LiYCl6:Ce Scintillators in Microgravity (CLYC-Crystal Growth), a Center for the Advancement of Science in Space (CASIS)-sponsored investigation, will study the potential benefits of growing the CYLC crystal in microgravity.

The CLYC crystal is a special kind of multicomponent crystal system used to make scintillator radiation detectors, a device that is sensitive to both gamma rays and neutrons.

"It's a spectroscopic crystal, which means, using this crystal, we can detect the presence and intensity of radiation, as well as identify which isotopes emit radiation by measuring the energy," said Dr. Alexei Churilov, primary investigator and senior scientist at Radiation Monitoring Devices Inc. (RMD).

The CLYC crystal is produced as a commercial product by RMD and is largely used to detect and differentiate both harmful and harmless levels of radiation. The crystal's main application is homeland security as a method of detected smuggled nuclear materials, but may also be used for oil and gas exploration, medical imaging, particle and space physics and scientific instruments.

However, the Earth-grown crystals have shown defects such as cracks, grain boundaries and inclusions, incidents which scientists like Churilov hope to eliminate by using the space station's microgravity environment as a growth habitat.

Research has shown that many, though not all, crystals benefit from growth in microgravity. Although the reasoning behind this phenomena is still being investigated, research points to the lack of buoyancy-induced convection, which affects transport of molecules in the crystal.

"Our ultimate goal is to study the growth of CLYC in microgravity without the interference of convection and to improve the production of the crystal on Earth," said Churilov.

The research for the CLYC Crystal Growth investigation will be conducted within the Solidification Using a Baffle in Sealed Ampoules Furnaces and Inserts (SUBSA Furnaces and Inserts). SUBSA helps researchers advance the understanding of processes involved in semiconductor crystal growth. It offers a gradient freeze furnace for materials science investigations. SUBSA was originally operated aboard the space station in 2002, the SUBSA hardware has been modernized and updated with data acquisition, high resolution video and communication interfaces.

During the investigation, four crystal growth runs will be conducted aboard the space station and then in the ground-based SUBSA furnaces, giving researchers a view into the gravitational effect on their growth. Once the investigation is complete, the space-grown crystals will be compared against their counterparts on Earth and tested for imperfections and effectiveness as radiation detectors.

Although microgravity can't be mimicked or reproduced on the ground, results from the investigation will provide information about which crystal methods to use on Earth, how to improve ampoule and furnace design and which crystal growth parameters to change in pursuit of a more perfect crystallization process.

Though the total weight of the CLYC Crystal Growth investigation is small, only a few kilograms together with packaging, the benefits can be immense as the data gathered during the investigation will be put to immediate use in the production of CLYC crystals.

Mysterious ‘Alien’ cylinder on NASA live feed for International Space Station spotted by space experts – Mirror.co.uk

Posted: at 2:04 am

NASA's live feed of the International Space Station (ISS) captured a mysterious object, which UFO experts claim is an alien cylinder that goes transparent.

The odd shape was spotted in a black space behind the ISS by space fans watching the live feed.

And experts said the cylinder - which they claim was a UFO - was 'partially transparent', which may be a technique used to keep the craft safe so that it is not seen.

UFO expert Scott C Waring, shared the footage and said: "I noticed a UFO in the distance that was coming closer and closer to the space station. The UFO was partially cloaked, which made it look transparent."

Mr Waring runs the website UFO Sightings Daily ,

He added: "In the deep blackness of spaces, blending into the environment means you will be safer from other alien species that may not be friendly."

It is not the first time objects have been spotted on the ISS feed without explanation.

In February, six large orbs were seen apparently creeping past the ISS in NASA footage.

In the live video, relayed by the American space agency, the UFOs move from the right of the screen towards the left. After they were seen conspiracy theorists claimed the live feed was cut.

Last year it was also suggested that a "nervous" astronaut was telling ground control about the appearance of a strange red-coloured UFO on the live NASA feed.

They claim he said the word "gospel" when the object appeared, and suggested this may have been a codeword as ground control replied "we pray for you."

A new method has used simulated Martian and lunar dust to 3D print flexible, tough rubber tools like these.

A new technique could allow the first humans on Mars to 3D print everything from tools to temporary housing out of a tough rubber-like material using only Martian dust.

The method could enable the first humans who set foot on the Red Planet to print the tools and housing they need to survive without having to lug all the supplies aboard their spaceship.

For places like other planets and moons, where resources are limited, people would need to use what is available on that planet in order to live, Ramille Shah, a materials scientist at Northwestern University in Illinois,said in a statement. Our 3D paints really open up the ability to print different functional or structural objects to make habitats beyond Earth. [Sending Humans to Mars: 8 Steps to Red Planet Colonization]

NASA has big plans for Martian exploration with Mars 2020. Only on CBS This Morning, Jan Crawford take a behind-the-scenes look at the assembly...

Any trip to Mars would requirespaceshipsbig enough to carry much more fuel and supplies than past spacecraft could, but care packages from Mother Earth wont be enough for humans to make it on an alien planet. Almost all schemes for colonizing the Red Planet (or for colonizing the moon) require that at least some of the supplies for the expeditions come from the local environment.

One step toward that goal would be to develop a super tool that could be used to quickly manufacture any other desired tool or object, using local resources. To that end, Shah and her colleagues wanted to see what could be made with some of the most abundant material on Mars and the moon: dust. The researchers used simulated dusts based on real lunar and Martian samples. The synthetic dust contains mixtures of aluminum oxide, silicon dioxide, iron oxide and other compounds. The hard particles simulating the lunar surface often have jagged, sharp edges, while Martian simulated dust is made up of rounder, less irregular particles, according to the researchers.

The team developed a process that combines simulated lunar andMartian dustwith solvents and a biopolymer to create these extraterrestrial inks. The inks were then 3D printed into different shapes using an extruder. In the end, the objects which were composed of about 90 percent dust were tough and flexible, and could withstand the rolling, cutting and folding needed to print almost any 3D shape, Shah and her colleagues reported online March 20 in the journalScientific Reports.

We even 3D-printed interlocking bricks,similar to Legos, that can be used as building blocks, Shah said.

While rubbery materials could have their uses, as a next step, Shah and her colleague David Dunand, a materials scientist at Northwestern University, are now trying to figure out ways to heat these rubbery polymers so they harden like ceramics.
