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.

Washington, Apr 12: The US has overtaken Italy as the country with the highest number of deaths due to COVID-19 pandemic with the fatalities crossing 20,000, according to Johns Hopkins University data, as the novel coronavirus continues to wreak havoc across the globe.

The deadly coronavirus, that originated in China in December last year, has so far killed more than one lakh people across the globe. The United States on Saturday became the country with the highest number of deaths at 20,597, surpassing Italy's 19,468 fatalities.

More than 5.3 lakh Americans have tested positive for coronavirus, which is about the same for the next four countries put together: Spain (163,027), Italy (152,271), Germany (125,452) and France (93,790). In terms of fatalities, the US and Italy are followed by Spain (16,606), France (13832) and United Kingdom (9,875), the varsity data showed.

New York City, the financial capital of the world, has emerged as the epicenter of coronavirus in the world. A city of 8.3 million, which is one of the most densely populated cities in the US, by Saturday night had as many as 8,627 deaths and more than 180,000 people had tested positive for COVID-19.

President Donald Trump has declared a national emergency and all the 50 States have been notified with major disaster declaration. More than 95 per cent of the country's 330 million population are under stay-at-home order. Trump has deployed more than 50,000 personnel from the armed forces in fight against COVID-19.

After an initial two-week social mitigation measures, that includes social distancing, the measures have been extended till April 30. Initially, members of the White House Task Force on Coronavirus had projected between one and two lakhs deaths. Now, they have dropped the projection to 60,000 deaths, mainly due to the successful implementation of these measures.

"The people of our country have gone through a lot. But we did it the right way. And we look like we'll be coming in on the very, very low side, really below the lowest, the lowest side of the curve of death," Trump told Fox News on Saturday night.

Trump asserted that situation was improving in places like New York, where there is a drop in new patients. Responding to a question, he said he wanted the country to open up as soon as possible.

However, he has not taken a decision so far, even as some media reports said that he the President was looking for early May.

"I think it's going to be the toughest decision that I've ever made. I really, hopefully that I ever will have to make. But it's certainly the toughest decision that I've ever made. I hope that I'm going to make the right decision," Trump said, adding that he will be making a decision reasonably soon.

"We're setting up a council now of some of the most distinguished leaders in virtually every field including politics and business and medical. We'll be making that decision fairly soon," Trump said.

Meanwhile, The New York Times reported that its investigations have revealed that the president was warned about a potential pandemic but that internal divisions, lack of planning and his faith in his own instincts led to a halting response.

According to The Washington Post, coronavirus is killing about one in 10 hospitalised middle-aged patients and four in 10 older than 85 in the United States. It is particularly lethal to men even when taking into account common chronic diseases that exacerbate risk.

Globally, the novel coronavirus has killed 108,862 people and infected over 1.7 million people globally. The US has the highest number of infections at 529,887, according to Johns Hopkins University data.

Canberra, May 21: Australian Prime Minister Scott Morrison and his Indian counterpart, Narendra Modi, are looking forward to deepening the countries' strategic relationship, with both sides expected to sign a range of pacts from defence to trade in strategic sectors amid heightened tensions with China over Beijing's response to coronavirus pandemic.

During a virtual summit, scheduled to take place on June 4, both leaders are expected to ramp up efforts to diversify Australia's export markets and find trusted suppliers of vital products and components, a local newspaper, The Australian reported on Tuesday.

The new agreements will focus on reliable supply chains in key strategic sectors, including medical goods, technology and critical minerals, amid heightened tensions with China over Beijing's response to coronavirus pandemic.

The leaders will seal a new defence agreement allowing reciprocal access to bases and co-operation on military technology projects, while a new education partnership will be on the table to help overcome Australian university reliance on Chinese students.

The talks in terms of strategic convergence, now have greater significance as COVID-19 exacerbates the strategic contest between the US and China, and forces like-minded countries to seek out reliable partners.

Australian farmers could also benefit, with talks underway on expanding agricultural exports to India, including barley, as China throws up new trade barriers, media reports stated.

The virtual summit follows the cancellation of Morrison's planned state visit to India in January due to the bushfires.

Morrison said last year, ahead of his planned visit, that India was "a natural partner for Australia", referring to the countries' "shared values" -- a point of differentiation with China.

Former Department of Foreign Affairs and Trade secretary Peter Varghese, who wrote a landmark report on the bilateral relationship in 2018, was quoted by the newspaper as saying that India would be even more important to Australia in the post-COVID world. "If one of the lessons from COVID is that countries need to spread their risk, then finding new markets or building up existing markets is a crucial part of that," he added.

Varghese noted that India, a member of the Quadrilateral Security Dialogue along with Australia, Japan and the US, was a vital strategic partner to Australia in helping "constrain China's ambitions to be the predominant power".

"That shared objective between Australia and India of not wanting to see the region dominated by China is a key component of building up our geopolitical relationship," he told The Australian.

The summit also follows recent talks between Australian Foreign Minister Marise Payne and Indian counterpart Subrahmanyam Jaishankar on the pandemic response and Australia's call for an independent inquiry, which was overwhelmingly backed at the World Health Assembly on Tuesday.

Australia wants to support India to develop a domestic critical minerals processing industry, which would provide Western nations with an alternative to sourcing the materials from China.

Meanwhile, India has strong expertise as a manufacturer of drugs and medical equipment, while Australia is a centre of biomedical research, opening the possibility for closer co-operation in the key sector, the media reported further.
