Nasa needs you: space agency to crowdsource origami designs for shield

If you know your crane from your bishop’s mitre, Nasa needs you. 

The space agency is launching a challenge to crowdsource origami-inspired ideas for a foldable radiation shield to protect spacecraft and astronauts on voyages to deep space, such as missions to Mars.

With the challenge open for entries from 26 July, innovative designs can be submitted through the website, Freelancer.

“The theory is that there will be a lot of people who have expertise in folding techniques or origami and [Nasa] want to find a very efficient way to pack a radiation shield,” said Matt Barrie, founder and CEO of Freelancer.

Helen O’Brien, a space engineer from Imperial College London who is not involved in the project, said that radiation shields – typically made of aluminium – are a crucial component of both manned and unmanned spacecraft.

“Essentially cosmic rays and other solar radiation can be very damaging to both people and electronics,” she said, pointing out that it can cause cancer, as well as triggering faults in circuits.

But, she noted, mass means money when it comes to space missions, and bulky items take up space that could be used for instruments – or people.

“Nasa want something that is sufficiently packed and compact so that when you actually land on a planet you can expand it and it will provide maximum efficiency and protection from radiation,” said Barrie.

As well as the radiation shield challenge, two other projects have been announced, one of which is asking for animation storyboards to help the space agency explain its experimental system for keeping track of objects inside the International Space Station (ISS). 

The other is to create a badge, known as a mission patch, for the space agency’s 3D printer-cum-recycling project, the “In Space Manufacturing Refabricator”.

The challenges are the latest in a series of conundrums posed to the public by the Nasa Tournament Lab and Freelancer. 

Previous challenges have ranged from suggestions for an app interface for astronauts’ smartwatches, to designing an arm for the Astrobee robot, that will help with tasks on the ISS.

“The whole premise is that by tapping into the minds of millions of people we will hopefully find unexpected solutions to problems that Nasa internally couldn’t come up with,” said Barrie.

It is not the first time space engineers have turned to the Japanese art for inspiration.

Among previous projects, earlier this year Nasa announced it had joined forces with researchers at Brigham Young University to create an origami-inspired folding radiator that allows the rate of heat loss to be controlled by changing its shape.

Robert J. Lang – an origami artist, world expert on the mathematics of origami and a former Nasa physicist – said that he was not surprised that Nasa was looking to the art for inspiration.

“Origami is a natural fit to many problems involving deployability in space, and Nasa has worked with origami artists – myself and others – over the years,” he said.

Mark Bolitho, a professional origami designer and an organiser of the international meeting on Origami in Science, Mathematics and Education to be held at the University of Oxford next year, added that applications extend beyond space.

“There have been many advances in the application of folding in science,” he said, citing innovations such as heart stents, car air bags, “and even experiments to fold at a molecular level.”

O’Brien, too, welcomed the use of origami in space engineering. 

“Origami is fantastic – the way that the intricate structures can be produced in such a small volume, but then also can be deployed to something that is really huge,” she said. 

“There is no reason why that kind of [approach] cannot be used to provide innovative and low mass shielding for space missions in the future.”

Armenian protesters block traffic, railways & airport as protest leader loses PM bid

Anti-government protesters disrupted traffic in Armenia’s capital, blocking railways and roads leading to Yerevan International Airport, after the parliament voted against opposition leader Nikol Pashinyan’s bid for interim PM.
Protesters managed to block streets connecting downtown Yerevan to residential districts, disrupting transportation in Armenia’s capital, footage from the scene shows. 
Yerevan’s metro system has also been paralyzed as demonstrators sit on the tracks, preventing trains from passing.
Meanwhile, protesters disrupted traffic on a road leading to Yerevan’s Zvartnots International Airport, located just 12km from the center of the city. 
Consequently, some passengers had to go the rest of the way on foot in order to catch their flights, according to Sputnik news agency.
Railway services have also been disrupted all across the country amid the demonstrations, a spokesman for South Caucasus Railways confirmed to Interfax. 
Some other highways, including the one connecting th…

Iran Killing Command: The use of firearms in dealing with protesters

The document you see on the image is the order of the commander of the Tehran repressive force to all the units based in the city.

Based on this agenda, the mercenaries of the corrupt government Islamic Republic of Iran have been allowed to use firearms in the event of any protest movement against people by the regime.
This is a murder command.
The repressive force of the law, known to the world's famous police and guardians, should protect the lives of its citizens, by freeing their mercenaries, they allow them to murder Iranians who are protesting the corruption in the government and you have the important message that if you come to the streets in protest of corruption and torture and massacre, we will kill you.
Because, according to criminal Khomeini, maintenance of the system is obligatory.
A corrupt government that is so hideous that spend billions of dollars from the national treasury and popular capitalto the suppression of its people and the countries of the region, must be ov…

ایران فرمان قتل : دستور استفاده از سلاح گرم در برخورد با معترضان

سندی که در تصویر میبینید دستور فرمانده نیروی سرکوبگر انتظامی تهران به همه یگانهای مستقر در این شهر است.
بر اساس این دستور کار ، مزدوران حکومت فاسد نظام جمهوری اسلامی اجازه یافته اند که درصورت بروز هرگونه جنبش اعتراضی از سوی مردم علیه رژیم ، از سلاح گرم استفاده کنند.
این دستور یک فرمان قتل است.
نیروی سرکوبگر انتظامی که به ظاهر و تعریف شناخته شده پلیس در سراسر جهان ، میبایست حافظ جان شهروندان باشد ، با آزاد گذاشتن دست مزدوران چکمه پوش خود انها را مجاز به قتل ایرانیان معترض به فسادهای موجود درلایه های حکومت میکنند و این پیام مهم را در خود دارد که اگر در اعتراض به  فساد و شکنجه و کشتار به خیابانها بریزید شما را خواهیم کشت.
چرا که به گفته خمینی دجال، حفظ نظام از اوجب واجبات است.
حکومت فاسدی که انقدر وقیح هست که میلیاردها دلار از خزانه ملی و سرمایه مردمی را صرف سرکوب مردم خود و کشورهای منطقه میکند باید سرنگون کرد.
اکنون چهل سال است که کشور ما به اشغال این ملایان جنایکتارخونخوار و اسلام تحمیلی در آمده است .
هنوز باورش برای برخی سخت است که درک کنند کشور ما به معنای واقعی کلمه از سوی بنیادگرایان الله…
