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.

May 14: The UN’s children agency has warned that an additional 6,000 children could die daily from preventable causes over the next six months as the COVID-19 pandemic weakens the health systems and disrupts routine services, the first time that the number of children dying before their fifth birthday could increase worldwide in decades.

As the coronavirus outbreak enters its fifth month, the UN Children’s Fund (UNICEF) requested USD 1.6 billion to support its humanitarian response for children impacted by the pandemic.

The health crisis is “quickly becoming a child rights crisis. And without urgent action, a further 6,000 under-fives could die each day,” it said.

With a dramatic increase in the costs of supplies, shipment and care, the agency appeal is up from a USD 651.6 million request made in late March – reflecting the devastating socioeconomic consequences of the disease and families’ rising needs.

"Schools are closed, parents are out of work and families are under strain," UNICEF Executive Director Henrietta Fore said on Tuesday.

 “As we reimagine what a post-COVID world would look like, these funds will help us respond to the crisis, recover from its aftermath, and protect children from its knock-on effects.”

The estimate of the 6,000 additional deaths from preventable causes over the next six months is based on an analysis by researchers from the Johns Hopkins Bloomberg School of Public Health, published on Wednesday in the Lancet Global Health Journal.

UNICEF said it was based on the worst of three scenarios analysing 118 low and middle-income countries, estimating that an additional 1.2 million deaths could occur in just the next six months, due to reductions in routine health coverage, and an increase in so-called child wasting.

Around 56,700 more maternal deaths could also occur in just six months, in addition to the 144,000 likely deaths across the same group of countries. The worst case scenario, of children dying before their fifth birthdays, would represent an increase "for the first time in decades,” Fore said.

"We must not let mothers and children become collateral damage in the fight against the virus. And we must not let decades of progress on reducing preventable child and maternal deaths, be lost,” she said.

Access to essential services, like routine immunisation, has already been compromised for hundreds of millions of children and threatens a significant increase in child mortality.

According to a UNICEF analysis, some 77 per cent of children under the age of 18 worldwide are living in one of 132 countries with COVID-19 movement restrictions.

The UN agency also spotlighted that the mental health and psychosocial impact of restricted movement, school closures and subsequent isolation are likely to intensify already high levels of stress, especially for vulnerable youth.

At the same time, they maintained that children living under restricted movement and socio-economic decline are in greater jeopardy of violence and neglect. Girls and women are at increased risk of sexual and gender-based violence.

The UNICEF pointed out that in many cases, refugee, migrant and internally displaced children are experiencing reduced access to protection and services while being increasingly exposed to xenophobia and discrimination.

“We have seen what the pandemic is doing to countries with developed health systems and we are concerned about what it would do to countries with weaker systems and fewer available resources,” Fore said.

In countries suffering from humanitarian crises, UNICEF is working to prevent transmission and mitigate the collateral impacts on children, women and vulnerable populations – with a special focus on access to health, nutrition, water and sanitation, education and protection.

To date, the UN agency said it has received USD 215 million to support its pandemic response, and additional funding will help build upon already-achieved results.

Within its response, UNICEF has reached more than 1.67 billion people with COVID-19 prevention messaging around hand washing and cough and sneeze hygiene; over 12 million with critical water, sanitation and hygiene supplies; and nearly 80 million children with distance or home-based learning.

The UN agency has also shipped to 52 countries, more than 6.6 million gloves, 1.3 million surgical masks, 428,000 N95 respirators and 34,500 COVID-19 diagnostic tests, among other items.

Sao Paulo, June 20: Brazil’s government confirmed on Friday that the country has risen above 1 million confirmed coronavirus cases, second only to the United States.

The country’s health ministry said that the total now stood at 10,32,913, up more than 50,000 from Thursday. The ministry said the sharp increase was due to corrections of previous days’ underreported numbers.

Brazilian President Jair Bolsonaro still downplays the risks of the virus after nearly 50,000 deaths from COVID-19 in three months, saying the impact of social isolation measures on the economy could be worse than the disease itself.

Specialists believe the actual number of cases in Brazil could be up to seven times higher than the official statistic. Johns Hopkins University says Brazil is performing an average of 14 tests per 1,00,000 people each day, and health experts say that number is up to 20 times less than needed to track the virus.

Official data show a downward trend of the virus in Brazil’s north, including the hard-hit region of the Amazon, a plateau in cases and deaths in the countries’ biggest cities near the Atlantic coast, but a rising curve in the south.

In the Brazilian countryside, which is much less prepared to handle a crisis, the pandemic is clearly growing. Many smaller cities have weaker health care systems and basic sanitation that’s insufficient to prevent contagion.

“There is a lot of regional inequality in our public health system and a shortage of professionals in the interior,” said Miguel Lago, executive director of Brazil’s Institute for Health Policy Studies, which advises public health officials.

That creates many health care deserts, with people going long distances to get attention. When they leave the hospital, the virus can go with them.

The cattle-producing state of Mato Grosso was barely touched by the virus when it hit the nation’s biggest cities in March. Sitting far from the coast, between the Bolivian border and Brazil’s capital of Brasilia, its 33 lakh residents led a mostly normal life until May. But now its people live under lockdown and meat producers have dozens of infected workers.

In Tangará da Serra, a city of 1,03,000 people in Mato Grosso, the mayor decided Friday to forbid the sale of alcoholic drinks for two weeks as an incentive for people to stay home.

Fᢩo Junqueira said the measure was needed after a spike in COVID-19 cases that filled 80% of the city’s 54 intensive care beds. The city has had nearly 300 cases of the disease, plus three fatalities.

In Rondonópolis, only 300 miles away from Tangará da Serra and home to a thriving economy, health authorities closed the local meatpacking industry after 92 cases were confirmed there. The city of 1,44,000 inhabitants counted 21 deaths from the virus and more than 600 cases. The mayor has also decided to limit sales of alcoholic beverages.

Even regions once considered examples of successful efforts against the virus are now struggling.

Porto Alegre, home to about 14 lakh people, had success in slowing the virus’ spread over the last three months. But now its mayor is considering increasing social isolation measures after ICU occupancy in the city jumped to 80% this month.

We were already making projections for schools to come back, Mayor Nelson Marchezan Jr. told The Associated Press. Now the trend is to impose more restrictions. Outside Sao Paulo city, five regions of the state’s countryside will have to close shops starting Monday due to a rise in coronavirus cases. Governor João Doria announced the decision Friday.

Dr. Mike Ryan, the World Health Organization’s executive director, said at a news conference that Brazil needs to increase its efforts to stop the spread of infections.

“The epidemic is still quite severe in Brazil. I believe health workers are working extremely hard and under pressure to be able to deal with the number of cases that they see on a daily basis,” Dr. Ryan said.

“Certainly the rise is not as exponential as it was previously, so there are some signs that the situation is stabilising. But we’ve seen this before in other epidemics in other countries.”

Margareth Dalcolmo, a clinical researcher and professor of respiratory medicine at the state-funded Oswaldo Cruz Foundation in Rio de Janeiro, believes the reopening in major cities and the virus traveling by road into Brazil’s heartland will keep the pressure on the country’s health system.

“The risk in the interior now is very big,” she said. “Our health system just can’t solve the most serious cases of COVID in many places of the countryside.”

London, Feb 12: Fugitive liquor baron Vijay Mallya returned to the courtroom here on Wednesday, the second day of hearing at the UK High Court, where the former billionaire has appealed against the extradition decision of Westminster Magistrates Court in December 2018.

On being asked about his expectations from the lengthy appeals process against the extradition order as today is the last day for Mallya to present his defence, the embattled former Kingfisher Airlines boss replied, "I have no clue. You see. I'll also see it. Let's not get into a speculative game."

When asked on what would happen if Mallya loses the case and has to return to India, the liquor baron responded: "We do have arguments."

The UK High Court, on Tuesday, had also heard Mallya's appeal against the Westminster Magistrates' Court order extraditing him to India to face alleged fraud and money laundering charges amounting to Rs 9,000 crore.

Mallya was present in the court along with his counsel Clare Montgomery during the hearing. Officials from Enforcement Directorate (ED) and Central Bureau of Investigation (CBI) along with counsel Mark Summers representing the Indian government were also present.

When the judge asked if there was a timeline in the case, Clare said," This is a very dense case," involving multiple individuals and organisations and that not everything had been taken into account by the magistrate Emma Arbuthnot in her ruling against Mallya.

Montgomery contended that the magistrate's ruling had been riddled with "multiple errors". She also brought into question the admissibility of documents submitted by the Indian government - including witness statements and emails that proved crucial in the ruling by judge Arbuthnot, who found "clear evidence of misapplication of loan funds" and that there was a prima facie case of fraud against Mallya.

As she had done throughout the trial, Montgomery continued to assert that Mallya had not acted in a fraudulent manner or run a pyramid and that the collapse of Kingfisher Airlines was, in fact, the failure of a business in difficult economic circumstances.

She also reiterated concerns about the conduct of the Central Bureau of Investigation (CBI) in bringing charges against Mallya, claiming that the tycoon had been made a scapegoat.

Montgomery also stated that the Indian government had presented the loan taken out by Kingfisher Airlines, not as a simple business loan but was part of a larger and elaborate attempt at defrauding the banks by Mallya and Kingfisher Airlines management.

This, Montgomery contended, was but one example of a wider misinterpretation of the case by judge Arbuthnot.

The High Court justices reprimanded Montgomery for concentrating on the evidence - in essence rehashing the case presented at the lower court - rather than the apparent "mistakes" made by judge Arbuthnot in her ruling.

Mallya remains on bail of £650,000 as he has done throughout this legal process.

The Crown Prosecution Service which is representing the Government of India will present its case for the extradition of Mallya on Wednesday.

The 63-year-old businessman fled India in March 2016 and has been living in the UK since then.
