NASA proposes 'Ice Home' design for future Mars explorers

December 30, 2016

Washington, Dec 30: The first explorers on Mars may build their homes using the ice beneath their feet to effectively protect them from the harsh martian environment and provide a safe place to call home, NASA scientists say.

iceWhen astronauts set foot on Mars, they may stay for months rather than days as they did during Apollo missions to the Moon.

The surface of Mars has extreme temperatures and the atmosphere does not provide adequate protection from high-energy radiation, NASA said.

These explorers will need shelters to effectively protect them from the harsh Martian environment and provide a safe place to call home.

According to researchers at NASA's Langley Research Centre in Virginia, the best building material for a new home on Mars may lie in an unexpected material: ice.

"Mars Ice Dome," is one of many potential concepts for sustainable habitation on the red planet in support of the agency's journey to Mars, NASA researchers said.

"After a day dedicated to identifying needs, goals and constraints we rapidly assessed many crazy, out of the box ideas and finally converged on the current Ice Home design, which provides a sound engineering solution," said Kevin Vipavetz, Langley senior systems engineer.

The "Mars Ice Home" is a large inflatable torus, a shape similar to an inner tube, that is surrounded by a shell of water ice.

The Mars Ice Home design has several advantages that make it an appealing concept, according to NASA. It is lightweight and can be transported and deployed with simple robotics, then filled with water before the crew arrives.

It incorporates materials extracted from Mars and because water in the Ice Home could potentially be converted to rocket fuel for the Mars Ascent Vehicle, the structure itself doubles as a storage tank that can be refilled for the next crew.

Another critical benefit is that water, a hydrogen-rich material, is an excellent shielding material for galactic cosmic rays – and many areas of Mars have abundant water ice just below the surface.

Galactic cosmic rays are one of the biggest risks of long stays on Mars. This high-energy radiation can pass right through the skin, damaging cells or DNA along the way that can mean an increased risk for cancer later in life or, at its worst, acute radiation sickness.

Space radiation is also a significant challenge for those designing potential Mars outposts. For example, one approach would envision habitats buried underneath the Martian surface to provide radiation shielding.

However, burying the habitats before the crews arrive would require heavy robotic equipment that would need to be transported from Earth.

Hello, 
I am writing from Space Exploration Architecture '?we are the team who designed Mars Ice House, the winner of NASA's Centennial Challenge for a 3D-Printed Habitat on Mars.

I noticed you posted a great article earlier this month about our project, Mars Ice Home. Could you please credit our project in your article by including a reference back to our website?

Aboard Air Force One, Jan 6: US President Donald Trump threatened sanctions against Baghdad on Sunday after Iraq's parliament called on US troops to leave the country, and the president said if troops did leave, Baghdad would have to pay Washington for the cost of the air base there.

"We have a very extraordinarily expensive air base that's there. It cost billions of dollars to build, long before my time. We're not leaving unless they pay us back for it," Trump told reporters on Air Force One.

Trump said that if Iraq asked US forces to leave and it was not done on a friendly basis, "we will charge them sanctions like they've never seen before ever. It'll make Iranian sanctions look somewhat tame."

Washington, Feb 21: US President Donald Trump has made yet another tall claim about the size of the crowd that will welcome him in Ahmedabad, saying Prime Minister Narendra Modi has told him that there will 10 million(1 crore) people to greet him on his arrival for his maiden visit to India.

President Trump and First Lady Melania are scheduled to travel to Ahmedabad, Agra and New Delhi on February 24 and 25.

Speaking to reporters at the Joint Base Andrews in Maryland on Tuesday, Trump said that Modi told him that "we'll have 7 million people between the airport and the event."

"So it's going to be very exciting. But he says between the stadium and the airport, we'll have about 7 million people. So it's going to be very exciting. I hope you all enjoy it," he said.

On Thursday, Trump upped the crowd size by three million at a 'Keep America Great' rally in Colorado.

"I hear, they are going to have 10 million people. They say anywhere from six to 10 million people are going to be showing up along the route to one of the largest stadiums in the world, the largest cricket stadium in the world, which is brand new and beautiful," said Trump, who is seeking reelection in the November presidential polls.

But according to a top civic official in Ahmedabad, the total population of the city is only around 70 lakh.

The authorities believe that between one to two lakh people are expected to line up along the 22-km route of the road show by Modi and Trump from the airport to the Motera cricket stadium, said to be the world's largest.

"We believe that around one to two lakh people will gather to welcome the dignitaries during the road show," Ahmedabad Municipal Commissioner Vijay Nehra said on Thursday, contradicting the claims made by the US President.

As per the road show route plan, Trump and Modi will first reach the Sabarmati Ashram, a place closely associated with Mahatma Gandhi, from Ahmedabad airport.

Addressing his supporters, Trump spoke about his India visit and said the "Namaste Trump" rally in Ahmedabad would spoil him.

"Prime Minister Modi said, we will have 10 million people greet you. Here's my problem. We have a packed house. We have a lot of people, thousands of people that couldn't get in. It's going to look like peanuts from now on," he said.

"I'll never be satisfied with the crowd. If we have 10 million people in India, how can I be satisfied when we fill up like a 60,000-seat stadium? I am getting spoiled," Trump said.

One of Trump's supporters from the audience then suggested that he build a bigger stadium.

Islamabad, Feb 29: A coalition comprising digital media giants Facebook, Google and Twitter (among others) have spoken out against the new regulations approved by the Pakistani government for social media, threatening to suspend services in the country if the rules were not revised, it was reported.

In a letter to Prime Minster Imran Khan earlier this month, the Asia Internet Coalition (AIC) called on his government to revise the new sets of rules and regulations for social media, The News International reported on Friday.

"The rules as currently written would make it extremely difficult for AIC Members to make their services available to Pakistani users and businesses," reads the letter, referring to the Citizens Protection Rules (Against Online Harm).

The new set of regulations makes it compulsory for social media companies to open offices in Islamabad, build data servers to store information and take down content upon identification by authorities.

Failure to comply with the authorities in Pakistan will result in heavy fines and possible termination of services.

It said that the regulations were causing "international companies to re-evaluate their view of the regulatory environment in Pakistan, and their willingness to operate in the country".

Referring to the rules as "vague and arbitrary in nature", the AIC said that it was forcing them to go against established norms of user privacy and freedom of expression.

"We are not against regulation of social media, and we acknowledge that Pakistan already has an extensive legislative framework governing online content. However, these Rules fail to address crucial issues such as internationally recognized rights to individual expression and privacy," The News International quoted the letter as saying.

According to the law, authorities will be able to take action against Pakistanis found guilty of targeting state institutions at home and abroad on social media.

The law will also help the law enforcement authorities obtain access to data of accounts found involved in suspicious activities.

It would be the said authority's prerogative to identify objectionable content to the social media platforms to be taken down.

In case of failure to comply within 15 days, it would have the power to suspend their services or impose a fine worth up to 500 million Pakistani rupees ($3 million).
