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.

Chengdu, China, Jul 27: The American flag was lowered at the United States consulate in Chengdu on Monday, days after Beijing ordered it to close in retaliation for the shuttering of the Chinese consulate in Houston.

Footage on state broadcaster CCTV from outside the consulate showed the flag being slowly lowered early Monday morning, after diplomatic tensions soared between the two powers with both alleging the other had endangered national security.

Relations deteriorated in recent weeks in a Cold War-style standoff, with the Chengdu mission Friday ordered to shut in retaliation for the forced closure of Beijing's consulate in Houston, Texas.

The deadline for the Americans to exit Chengdu has been unclear, but the Chinese consulate in Houston was given 72 hours to close after the original order was made.

On Saturday news agency reporters saw workers removing the US insignia from the front of the consulate.

Over the weekend, removals trucks entered the US consulate and cleaners were seen carting large black rubbish bags from the building.

Beijing says closing the Chengdu consulate was a "legitimate and necessary response to the unreasonable measures by the United States", and has alleged that staff at the diplomatic mission endangered China's security and interests.

Washington officials, meanwhile, said there had been unacceptable efforts by the Chinese consulate in Houston to steal US corporate secrets.

Beijing, Jun 16: The coronavirus situation in China's capital is "extremely severe", a city official warned Tuesday, as 27 new infections were reported from Beijing where a new cluster has sparked a huge trace-and-test programme.

The COVID-19 resurgence -- believed to have started at the sprawling Xinfadi wholesale food market in the capital -- has sparked alarm as China had largely brought its outbreak under control through mass testing and lockdowns imposed earlier in the year.

The new cases took the number of confirmed infections in Beijing over the past five days to 106, as authorities locked down almost 30 communities in the city and tested tens of thousands of people.

"The epidemic situation in the capital is extremely severe," Beijing city spokesman Xu Hejian warned at a press conference.

The World Health Organization had already expressed concern about the cluster, pointing to Beijing's size and connectivity.

Officials in the capital have said they will test stall owners and managers at all of the city's food markets, restaurants and government canteens.

Beijing's coronavirus testing capacity has been expanded to 90,000 a day, according to China's official news agency Xinhua.

On Tuesday, the capital's transport commission banned taxi- and ride-hailing services from driving out of the city, Xinhua reported, in another move to try and contain the new outbreak.

All indoor sports and entertainment venues in Beijing were ordered to shut on Monday, and some other cities across China warned they would quarantine those arriving from the capital.

The National Health Commission also reported four new domestic infections in Hebei province, which surrounds Beijing, and a case reported in southwestern Sichuan province was linked to the Beijing cluster.

Authorities were also racing to track people from Beijing who had travelled to other parts of China, and those who visited the capital have been encouraged to get tested.

Beijing spokesman Xu said: "High-risk people who have left Beijing must inform local authorities immediately."

Market inspections

Authorities shut down another market on Tuesday -- Tiantaohonglian in the central Xicheng district -- after one employee there was diagnosed with COVID-19, state broadcaster CCTV reported.

Seven residential estates surrounding that market were also locked down.

In total, Beijing officials said Tuesday they have disinfected 276 agricultural markets, closed 11 markets, and disinfected more than 33,000 food and beverage businesses in a bid to stamp out the new cluster.

Officials had warned Sunday that since May 30, 200,000 people had visited the Xinfadi market -- the original site of the new outbreak.

More than 8,000 workers from Xinfadi have been tested and sent to centralised quarantine facilities.

Until this recent outbreak, most of China's cases in recent months were nationals returning home as the pandemic spread to other countries.

China's Center for Disease Control and Prevention said Monday that the virus strain found in the Beijing outbreak was a "major epidemic strain in the European countries".

While the virus was detected on chopping boards used to handle imported salmon at Xinfadi, "it does not clearly or definitely indicate it's from imported seafood", Wu Zunyou, the body's chief epidemiologist, said in an interview with state broadcaster CCTV.

"Ever since new cases suddenly emerged in Beijing, we have tried to figure out the reasons for the outbreak since there were no COVID-19 cases found over the past two months," Wu Zunyou said.

"We came up with several possibilities, and the most likely one is that the carrier of the novel coronavirus comes from outside China or other parts of China and brought it here."

On Tuesday, another eight imported cases were reported.

Brussels/Amsterdam, Apr 16: As the novel coronavirus continues to wreak havoc in the western world since its outbreak in Wuhan last December, researchers believe that the Chinese leadership is trying to absolve President Xi Jinping by using a section of the western media to influence public opinion globally.

"There are clear indications that China is conducting activities in a persistent and systematic manner to influence public opinion-making, academia, think tanks and political decision-making among the member states of the Belt and Road Initiative (BRI) in general and western capital cities in particular," Siegfried O Wolf, Director of Research at Brussels-based think tank South Asia Democratic Front, said.

Some western media say some Chinese officials were secretly aware that they were facing a pandemic from the new coronavirus but allowed Wuhan to host a mass banquet for tens of thousands of people and millions began their annual trip home for the Lunar New Year celebrations.

The pandemic has since then affected 210 countries and territories around the world. Over 2 million people have been declared positive in which over 134,000 lost their lives.

"The frequency and extra-ordinary large scale of Chinese sponsored events in European political hubs, like in Brussels, and the subsequent media coverage can be seen as evidence for Beijing's public diplomacy efforts. However, the rising skepticism within the EU regarding Xi Jinping's development projects and the emerging questioning of Chinese sources funding Free Universities, like the one in Berlin, shows that this strategy produced mixed results so far," Wolf said.

He added, "However, one must also state that these efforts helped China to gain certain leverage among many non-Chinese media, western as well as non-western ones. Today, we can observe that China's political leadership tries to instrumentalise this influence for a major image campaign to distract from the fact that it carries the initial responsibility for the dramatic spread of COVID-19 by holding back key information."

Wolf also said that the current internal dynamics in China, like the shirking of responsibilities by the local authorities, are most-likely part of a twofold strategy. Firstly, there is the strategic component - namely, to reaffirm to the general public that the Communist Party of China is still in full control of the situation. The second strategic pillar is one of 'whitewashing'.

"Concretely, Beijing's obvious aim is to distract the domestic and international attention from the real, but hidden causes of the Coronavirus outbreak and its potential reputational and political consequences for Xi Jinping and his BRI," he stated.

Yoana Barakova, a Research Analyst at European Foundation for South Asian Studies (EFSAS), an Amsterdam-based think-tank, said, "The death of Dr. Li Wenliang, one of the very few medical professionals who tried to warn the world in December 2019 about the looming threat, sparked widespread condemnation around the international community in early February. Yet, little did he know that his legacy would continue much later after his demise, with the emboldened Chinese government trying to cover up its missteps through hardcore censorship after being exposed for undermining and underestimating the initial danger."

The researchers believe that the deterioration in press freedom under Jinping's regime has become more evident in recent days, with local authorities trying to control the state narrative by cosmetically placing media's focus on government's superficial attempts to tackle the crisis.
