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.

For the first time in the 15 years of the Global Risks Report, the climate change and environment risk has occupied all the top five slots.

According to the 15th edition of the World Economic Forum's (WEF) Global Risks Report, the top five risks in terms of likelihood are extreme weather, climate action failure, natural disasters, biodiversity loss and human-made environmental disasters. They all fall in the one category of climate change and related environmental disasters.

WEF President Borge Brende said the world was feeling long-mounting and interconnected risks.

The report also points to how citizens are protesting across the world as discontent rises with failed systems that are creating inequality. The citizens' discontent had hardened with systems that had failed to promote advancement, it said.

"Disapproval of how governments are addressing profound economic and social issues has sparked protests throughout the world, potentially weakening the ability of governments to take decisive action should a downturn occur. Without economic and social stability, countries could lack the financial resources, fiscal margin, political capital or social support needed to confront key global risks," it said.

Listing the grim scenario, Borge said the global economy was faced with "synchronised slowdown", the past five years had been the warmest on record and cyber attacks were expected to increase this year.

The report warns that while the myriad risks were rising, time was running out on how to prevent them.

Borge said the growing palpability of shared economic, environmental and societal risks indicated that the horizon had shortened for preventing "or even mitigating" some of the direst consequences of global risks.

"It's sobering that in the face of this development, when the challenges before us demand immediate collective action, fractures within the global community appear to only be widening," he said.

The report points to grave concern about the consequences of continued environmental degradation, including the record pace of species decline.

Pointing to an unsettled geopolitical environment, the report said today's risk landscape was one in which new centres of power and influence were forming and old alliance structures and global institutions were being tested.

"While these changes can create openings for new partnership structures in the immediate term, they are putting stress on systems of coordination and challenging norms around shared responsibility. Unless stakeholders adapt multilateral mechanisms for this turbulent period, the risks that were once on the horizon will continue to arrive," it said.

Calling it a "an unsettled world", the WEF report notes that powerful economic, demographic and technological forces were shaping a new balance of power. "The result is an unsettled geopolitical landscape in which states are increasingly viewing opportunities and challenges through unilateral lenses," it said.

"What were once givens regarding alliance structures and multilateral systems no longer hold as states question the value of long-standing frameworks, adopt more nationalist postures in pursuit of individual agendas and weigh the potential geopolitical consequences of economic decoupling. Beyond the risk of conflict, if stakeholders concentrate on immediate geo-strategic advantage and fail to re-imagine or adapt mechanisms for coordination during this unsettled period, opportunities for action on key priorities may slip away," the WEF said.

In a chapter on risks to economic stability and social cohesion, it said a challenging economic climate might persist this year and members of the multi-stakeholder community saw "economic confrontations" and "domestic political polarisation" as the top risks in 2020.

The report also warned of downward pressure on the global economy from macroeconomic fragilities and financial inequality. These pressures continued to intensify in 2019, increasing the risk of economic stagnation.

Low trade barriers, fiscal prudence and strong global investment, once seen as fundamentals for economic growth, are fraying as leaders advance nationalist policies. The margins for monetary and fiscal stimuli are also narrower than before the 2008-2009 financial crisis, creating uncertainty about how well countercyclical policies will work.

The strategic partners for the WEF report included Marsh & McLennan and Zurich Insurance Group. The academic advisers were National University of Singapore, Oxford Martin School, University of Oxford and Wharton Risk Management and Decision Processes Center, University of Pennsylvania.

Wuhan, Feb 23: Ninety-seven more people died in China due to coronavirus, taking the death toll to 2,442, officials said on Sunday, as a team of WHO experts visited the worst-affected Wuhan city in Hubei province.

By the end of Saturday, a total of 2,442 people had died of the disease and 76,936 confirmed cases of novel coronavirus infection had been reported in 31 provincial-level regions, China's National Health Commission (NHC) said in its daily update on Sunday.

Ninety-six deaths were reported from Hubei province and one from Guangdong province on Saturday besides 648 new confirmed cases of coronavirus infections, it said.

Hubei province, where the virus first emerged in December last, reported 630 new confirmed cases, taking the total confirmed cases in the hard-hit province to 64,084, state-run Xinhua news agency reported.

The NHC also said China's daily number of newly cured and discharged novel coronavirus patients has surpassed that of new confirmed infections for the fifth consecutive day, indicating that cases of infections are coming down.

Saturday saw 2,230 people walk out of hospital after recovery, much higher than the number of the same day's new confirmed infections, which was 648, Xinhua reported.

A total of 22,888 patients infected with the novel coronavirus had been discharged from hospital after recovery by the end of Saturday, NHC said.

Meanwhile, a team of public health experts from the World Health Organisation (WHO) visited Wuhan on Saturday to conduct a detailed probe about the virus which reportedly originated from a seafood market in the city in December last year.

The NHC said WHO experts along with their Chinese counterparts who formed a joint investigation team have held talks with the local health authority in Wuhan and visited relevant healthcare institutions.

The UN team comprises specialists from the United States, Germany, Japan, Nigeria, Russia, Singapore and South Korea, Hong-Kong based South China Morning Post reported.

The 12-member team, which arrived in China on Monday, was initially designated to visit only Beijing, Guangdong and Sichuan provinces, while the worst-affected Hubei province and its capital Wuhan were missing from the list.

However, the team was finally given permission to visit Wuhan by the Chinese government.

Besides controlling the spread of the virus, a major task for the WHO team along with their Chinese counterparts was to come up with standard medicine to cure the disease.

The NHC said on Saturday that the team had met top Chinese respiratory disease expert Zhong Nanshan in Guangdong, and visited the centre for disease control and prevention in Guangdong and the city of Shenzhen, and Sichuan.

The specialists also discussed quarantine measures, the wild animal trade and community prevention measures with their Chinese counterparts, it said.

Washington, Apr 9: At least 11 Indians have died of COVID-19 in the United States with another 16 testing positive for the infection which has claimed more than 14,000 lives and afflicted more than four lakh people in the US.

All Indian citizens who have succumbed to the deadly infection in the US are male, with ten of them from New York and New Jersey area. Four of the victims are said to be taxi drivers in New York City.

New York City has emerged as the US epicentre for COVID-19 spurt, accounting for more than 6,000 deaths and over 1,38,000 cases of infections. New Jersey accounts for 1,500 fatalities and nearly 48,000 infections.

One Indian national reportedly died in Florida because of coronavirus. Authorities are also ascertaining the nationality of some other Indian origin people in the States of California and Texas.

All 16 Indians, including four females, who have tested positive for coronavirus are in self-quarantine. Coming from diverse background, eight of them are from New York, three from New Jersey and rest from other states like Texas and California. They hail from Indian states like Uttarakhand, Maharashtra, Karnataka and Uttar Pradesh.

Indian Embassy and consulates across the United States are working closely with local authorities and Indian-American organizations to provide necessary assistance to Indian nationals and students affected with COVID-19.

Because of the strict travel restrictions and regulations to prevent the spread of the deadly virus, local city officials have been performing the last rites of the deceased and in many cases are not allowing even their immediate family members to attend their cremations, officials said.
