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.

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.

Jun 13: Requiring the wearing of masks to prevent the spread of the novel coronavirus in areas at the epicenter of the global pandemic may have prevented tens of thousands of infections, a new study suggests.

Mask-wearing is even more important for preventing the virus' spread and the sometimes deadly COVID-19 illness it causes than social distancing and stay-at-home orders, researchers said, in the study published in PNAS: The Proceedings of the National Academy of Sciences of the USA.

Infection trends shifted dramatically when mask-wearing rules were implemented on April 6 in northern Italy and April 17 in New York City - at the time among the hardest hit areas of the world by the health crisis - the study found.

"This protective measure alone significantly reduced the number of infections, that is, by over 78,000 in Italy from April 6 to May 9 and over 66,000 in New York City from April 17 to May 9," researchers calculated.

When mask-wearing went into effect in New York, the daily new infection rate fell by about 3% per day, researchers said. In the rest of the country, daily new infections continued to increase.

Direct contact precautions - social distancing, quarantine and isolation, and hand sanitizing - were all in place before mask-wearing rules went into effect in Italy and New York City. But they only help minimize virus transmission by direct contact, while face covering helps prevent airborne transmission, the researchers say.

"The unique function of face covering to block atomization and inhalation of virus-bearing aerosols accounts for the significantly reduced infections," they said. That would indicate "that airborne transmission of COVID-19 represents the dominant route for infection."

The U.S. Center for Disease Control and Prevention on Friday urged organizers of large gatherings that involve "shouting, chanting or singing to strongly encourage the use of cloth face coverings to lower the risk of spreading the coronavirus."

Wuhan, Jan 20: A 45-year-old Indian woman has become the first foreigner in China to have contracted a mysterious virus, which is suspected to be Severe Acute Respiratory Syndrome (SARS)-like corona virus.

In 2002-2003, the SARS corona virus killed around 650 people in China and Hong Kong. This time, a new strain of virus with 62 cases have been reported in Wuhan and two in Shenzhen so far. 19 patients have been already cured and discharged, as per the Chinese media.

Official sources in Beijing said that the patient, Preeti Maheshwari, a school teacher at an international school, is undergoing treatment for the new strain of pneumonia outbreak, which has been spreading in two major cities of China - Wuhan and Shenzen. She has been on a ventilator in the intensive care unit.

Maheshwari was admitted to a local hospital after she seriously fell ill last Friday. Her husband, a businessman from Delhi, is allowed to visit her daily.

Following a second death due to the outbreak of the virus in Wuhan, India on Friday issued an advisory to its nationals travelling to China. Over 500 Indian medical students are studying in Wuhan.
