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.

Geneva, Mar 30: The number of confirmed COVID-19 cases worldwide has reached 634,835, among them 29,957 fatalities, the World Health Organization (WHO) said on Sunday.

Over the past 24 hours, 63,159 people were confirmed to be infected with the novel coronavirus and 3,464 people died, the WHO said.

According to the latest situation report, the majority of the confirmed cases - more than 361,000 - are presently concentrated in Europe, with Italy leading the tally with over 92,000 cases, followed by Spain with over 72,000 cases, and Germany with over 52,000 cases.

Italy and Spain are also the countries that top the worldwide death toll from COVID-19, with 10,023 and 5,690 fatalities, respectively.

The second most affected region is currently the Americas with over 120,000 verified COVID-19 cases, of which the majority - over 103,000 - have been found in the United States. The US is also the country with the highest single tally of COVID-19 cases at the moment.
The WHO declared COVID-19 a pandemic on March 11.

Beijing, Mar 12: The number of fresh infections at the epicentre of China's coronavirus epidemic dropped to a new low on Thursday but the country imported more cases from abroad.

Another 11 people died, the lowest daily increase since late January, bringing the toll in China to 3,169 deaths, according to the National Health Commission.

There were only eight new cases in Wuhan, the city where the virus first emerged in December before growing into a national crisis and a pandemic.

It is the first time that new cases in Wuhan, the capital of Hubei province, have fallen to single-digits since figures started to be reported in January.

With cases falling dramatically in recent weeks, authorities this week began to loosen some restrictions on Hubei's 56 million people, who have been under quarantine since late January.

Healthy people living in low-risk areas of the province can now travel within Hubei. While Wuhan is not included, some of the city's companies were told they could resume work.

Only one other non-imported case was recorded elsewhere in the country.

But as global hotspots emerge elsewhere, China fears that cases arriving from abroad could undermine its progress.

On Thursday there were six more imported cases reported, bringing the total of infections from overseas to 85, health officials said.

Beijing has ordered a 14-day quarantine for everyone arriving in the city from any country.

Travellers flying into Beijing Capital International Airport from high-risk countries are now handled separately from other passengers.

A total of 80,793 people have now been infected in China.

President Xi Jinping said this week during his first visit to Wuhan since the crisis erupted that the spread of the disease has been "basically curbed" in China.

Melbourne, Mar 18: Australian Prime Minister Scott Morrison on Wednesday warned its citizens not to travel abroad and banned "non-essential" gatherings of 100 people or more as the government declared the deadly coronavirus, that has infected over 450 people in the country, a "human biosecurity emergency".

Prime Minister Morrison on Wednesday said Australians should abandon all overseas travel because of the coronavirus epidemic. There have been 40 new cases since Tuesday.

Of the 454 confirmed cases in Australia, 43 have recovered and 5 have died from the COVID-19, according to the official figures.

Morrison declared a national "human biosecurity emergency" and ordered a halt to "non-essential" indoor gatherings of more than 100 people, on top of an existing ban on outdoor events of more than 500.

He said, "We haven't seen this sort of thing in Australia since the end of the First World War. This is a once-in-a-100-year-type event," Morrison said.

"Life is changing in Australia, as it is changing all around the world. Life is going to continue to change. The travel advice to every Australian is do not travel abroad. Do not go overseas."

However, schools across the country were still to remain open.

Morrison said Australia should prepare for "at least six months" of disruption as health authorities attempt to get on top of the coronavirus.

"For those of you thinking about going overseas for the school holidays, don’t. Don't go overseas," he said.

Morrison said there would be no short-term, quick fix to deal with the COVID-19 crisis in Australia, and warned that "tens of thousands of jobs" could be lost.

Responding to the panic buying, the prime minister urged the public to "Stop hoarding."

"I can't be more blunt about it. Stop it. It is not sensible, it is not helpful and it has been one of the most disappointing things I have seen in Australian behaviour in response to this crisis," he said.

On Wednesday, the New South Wales recorded a massive jump in new 59 cases as travellers returned from overseas. The cases jumped from 210 to 269 in the past 24 hours, according to the media reports here.

Queensland's total number of confirmed cases stood at 94.

State Premier Annastacia Palaszczuk said it is now "a different world" from just last week.

For Victoria, the Premier Daniel Andrew said the government could also ban gatherings of fewer than 100 people, noting he could not rule out further changes.

Chief Health Officer Brett Sutton said the spike in cases has been due to people who have travelled overseas.

Sutton said that the transmission in Victoria was not because of community transition like Italy.

Sutton has continued to urge people to wash their hands, socially distance and stay home if they are unwell.

"These are critical measures to be applied regardless of the 100 and 500 threshold,” he said.

In Western Australia, Health Minister Roger Cook said four new coronavirus cases have been confirmed overnight, taking the State's total to 35.

McGowan also condemned panic buyers in supermarkets as "jerks, drongos and bloody idiots."

He said there was "plenty of food to go round" and no need for people to buy in excessive quantities.

The outbreak, which first emerged in China's Wuhan city last year, has marched across the globe, infecting 198,006 people and killing 7,948, according to a tracker maintained by the Johns Hopkins University.
