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.

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.

Washington, Apr 8: President Donald Trump has threatened to put a "very powerful" hold on US' funding to the World Health Organization, accusing the UN agency of being "very China centric" and criticising it for having "missed the call" in its response to the coronavirus pandemic.

Trump slammed the global health agency for its early guidance aimed at countering the international spread of the coronavirus.

"We're going to put a hold on money spent to the WHO. We're going to put a very powerful hold on it and we're going to see. It's a great thing if it works. But when they call every shot wrong, that's no good," Trump told reporters at his daily White House news conference on Tuesday.

The Geneva-headquartered World Health Organization (WHO), receives vast amounts of money from the United States.

"We pay for a majority or the biggest portion of their money. They actually criticized and disagreed with my travel ban at the time I did it. They were wrong. They've been wrong about a lot of things. They had a lot of information early and they didn't want to - they're very - they seem to be very China centric," Trump said.

The president said his administration was going to look into the US funding to the WHO.

"We give a majority of the money that they get, and it's much more than the USD 58 million. USD 58 million is a small portion of what they've got over the years. Sometimes they get much more than that. Sometimes it's for programs that they're doing, and-it's much bigger numbers. If the programmes are good, that's great as far as we're concerned," he said.

"But we want to look into it, WHO, because they called it wrong. They (WHO) called it wrong. They missed the call. They could've called it months earlier. They would have known and they should have known and they probably did know. So, we'll be looking into that very carefully, and we're going to put a hold on money spent to the WHO," Trump said.

Meanwhile, Senator Jim Risch, chairman of Senate Foreign Relations Committee, called for an independent investigation into the WHO's handling of the COVID-19 response.

"The WHO has failed not only the American people, it has failed the world with its flagrant mishandling of the response to COVID-19," said Risch.

WHO Director general Tedros Adhanom Ghebreyesus' apparent unwillingness to hold the Chinese Communist Party to even the minimum standard of global health and transparency hindered the world's ability to blunt the spread of this pandemic, he said.

"It is completely unacceptable that the world's global health organization has become a political puppet of the Chinese government," he alleged, adding that "an independent investigation into the WHO's handling of the COVID-19 response is imperative."

The United States is the largest contributor to the WHO.

"Our valuable tax payer dollars should go towards investments to prevent the spread of disease, not to aid and abet cover-ups that cost lives and isolate portions of the world's population on political grounds, as has been the case with Taiwan," Senator Risch said.

A bipartisan group of nearly two dozen lawmakers announced Tuesday to introduce a resolution to defund the WHO until Ghebreyesus resigns and an international commission investigates the organisation's role in covering up the Chinese Communist Party's failed COVID-19 response.

"The WHO helped the Chinese Communist Party hide the threat of COVID-19 from the world and now more than 10,000 Americans are dead, a number that is expected to rise dramatically in the coming weeks," Congressman Guy Reschenthaler alleged.

"The United States is the largest contributor to WHO. It is not right that Americans' hard-earned tax dollars are being used to propagate China's lies and hide information that could have saved lives. This bill will hold the WHO accountable for their negligence and deceit," he asserted.

The United States' intelligence community has reported that the Chinese government hid the threat of COVID-19 and, as a result, made it difficult for the rest of the world to respond early, appropriately and aggressively, said Congressman Fred Keller.

"For reasons beyond understanding, the WHO acted as a silent partner in this effort instead of protecting the lives of millions across the world, including hundreds of thousands of American citizens. Our hard-earned tax dollars should not go to a global organization more concerned with not offending the Chinese government than providing accurate information and protecting innocent lives," Keller said.

Senator Marco Rubio accused the Chinese Communist Party of using WHO "to mislead the world."

"The organisation's leadership is either complicit or dangerously incompetent. I will work with the Trump Administration to ensure that WHO is independent and has not been compromised by the CCP before we continue our current funding, he added.

According to Johns Hopkins University, there are over 1.43 million confirmed coronavirus cases across the world and over 82,000 people have died due to the disease. The US has nearly 400,000 infections, the highest in the world.

Hong Kong, Jun 10: The Hong Kong police on Wednesday said they had arrested 53 people during demonstrations on Tuesday evening which were called to mark the one-year anniversary of the protest against a bill proposing extraditions to mainland China. That protest grew into a pro-democracy movement and sparked seven months of protests against Beijing's rule.

Hundreds of activists took to the streets in Hong Kong yesterday, at times blocking roads in the heart of the city, before police fired pepper spray to disperse crowds, Al Jazeera reported.

The police informed that 36 males and 17 females were arrested for offenses including unlawful assembly and disorderly conduct.

Protesters had defied a ban on gatherings of more than eight people introduced by the Hong Kong government to prevent the spread of the coronavirus.

"Lawful protests are always respected, but unlawful acts are to be rejected. Please stop breaking the law," police said in a tweet.

More protests are being planned in the coming days, with pro-democracy supporters fearing the proposed national security legislation will stifle freedoms in the city.

While details of the security law or how it will operate have yet to be revealed, authorities in Beijing and Hong Kong have said there is no cause for concern and the legislation will target a minority of "troublemakers".

But critics say the law would destroy the civil liberties Hong Kong residents enjoy under the "one country, two systems" agreement put in place when the United Kingdom handed the territory back to China in 1997. The agreement is set to end in 2047.

Japan had already issued a statement independently expressing serious concern about Beijing's move on May 28, the day China approved the decision and called in the Chinese ambassador to convey its view.

The United States, Britain, Australia, and Canada also condemned the move, with Washington saying it would revoke Hong Kong's special trading status granted under a 1992 law on the condition that the city retains key freedoms and autonomy.

China blames the protests in part on foreign intervention and is rushing to enact the national security law aimed at curbing secessionist and subversive activities in Hong Kong.
