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?

The Seattle City Council, one of the most powerful city councils in the U.S., on Monday unanimously passed a resolution condemning India’s recently-enacted Citizenship Amendment Act (CAA) and the National Register of Citizens (NRC).

Reaffirming Seattle as a welcoming city and expressing solidarity with the city’s South Asian community regardless of religion and caste, the resolution “resolves that the Seattle City Council opposes the National Register of Citizens and the Citizenship Amendment Act in India, and finds these policies to be discriminatory to Muslims, oppressed castes, women, indigenous, and LGBT people“.

Introduced by Indian American City Council member Kshama Sawant, the resolution urges the Parliament of India to uphold the Indian Constitution by repealing the CAA, and to stop the National Register of Citizens, and take steps towards helping refugees by ratifying various UN treaties on refugees.

“Seattle City’s decision to condemn CAA should be a message to all who wish to undermine pluralism and religious freedom. They cannot peddle in hate and bigotry, and expect to have international acceptability at the same time,” said Ahsan Khan, president of Indian American Muslim Council.

Thenmozhi Soundararajan of Equality Labs, which organised the community in support of the resolution, welcomed its passage. “We are proud of the Seattle City Council for standing on the right side of history today. Seattle is leading the moral consensus in the global outcry against the CAA, she said.

Soundararajan said that thousands of organizers across the country have called, e-mailed, and visited Seattle City Council members to amplify this resolution, and it sets an example to cities across the United States.

“At a time when members of the Indian ruling party sided Trump, the Muslim ban, and his war on immigrants as justification for targeting hundreds of millions of Indian minorities, Americans have a unique responsibility to stand up and speak about this human rights crisis. We are glad that Seattle is leading the way on this,” she said.

The head of the World Health Organisation on Tuesday warned the novel coronavirus was a "very grave threat" for the world as he opened a conference to combat the epidemic.

"With 99% of cases in China, this remains very much an emergency for that country, but one that holds a very grave threat for the rest of the world," Tedros Adhanom Ghebreyesus said in Geneva.

Some 400 scientists will review how the virus is transmitted and possible vaccines at the two-day forum.

"What matters most is stopping the outbreak and saving lives. With your support, that's what we can do together," Tedros said.

The virus, first identified in China on December 31, has killed more than 1,000 people, infected over 42,000 and reached some 25 countries.

Participants will also discuss the source of the virus, which is thought to have originated in bats and reached humans via another animal such as snakes or pangolins.

There is no specific treatment or vaccine against the virus, which can cause respiratory failure.

Tedros, who has repeatedly urged countries affected to share their data, called for global "solidarity".

"That is especially true in relation to the sharing of samples and sequences. To defeat this outbreak, we need open and equitable sharing, according to the principles of fairness and equity," he said.

"We hope that one of the outcomes of this meeting will be an agreed roadmap for research around which researchers and donors will align," Tedros said.

Several companies and institutes in Australia, China, France, Germany and the United States are racing to develop a vaccine -- a process that normally takes years.

Asked whether scientists from Taiwan would be allowed to take part in this week's Geneva conference, WHO officials said that they would do so but only online -- along with colleagues from other parts of China.

While the WHO does not deal with Taiwan directly and only recognises Beijing, Taiwan was often allowed to attend annual assemblies and sideline meetings as an observer.

But in recent years it has been frozen out as Beijing takes an increasingly combative stance towards democratic Taiwan, which it considers its own territory.

Washington, May 20: The United States recorded another 1,536 coronavirus deaths over the past 24 hours, the Johns Hopkins University tracker said.

That figure, tallied as of 8:30 pm (0030 GMT), raises to 91,845 the total number of COVID-19 deaths in the US.

The US tops the global rankings both for the highest death toll and the highest number of infections, with more than 1.5 million cases.
