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, Mar 29: The number of known coronavirus US cases soared well past 115,000, with more than 1,900 dead, as President Donald Trump said on Saturday he was considering imposing a quarantine on the hard hit New York region.

American healthcare workers in the trenches of the pandemic are appealing for more protective gear and equipment to treat a surge in patients that is already pushing hospitals to their limits in virus hot spots such as New York City, New Orleans and Detroit.

Trump told reporters he could order a quarantine on three states, New York, New Jersey and Connecticut, which between them have recorded at least 64,000 infections and 895 deaths.

He also appeared to soften his previous comments calling for the US economy to be swiftly reopened. Asked whether he thought the United States would restart by Easter Sunday, April 12, Trump replied, "We'll see, what happens."

New York Governor Andrew Cuomo said he had no details on any possible quarantine order for his state, telling a briefing: "I don't even know what that means. I don't know how that would be legally enforceable, and from a medical point of view I don't know what you would be accomplishing."

He said New York was postponing its presidential primary election to June 23, from April 28.

As the crisis deepened, nurses at Jacobi Medical Center in New York's borough of the Bronx protested outside the hospital on Saturday, saying supervisors asked them to reuse personal protective equipment, including masks. Some held signs with slogans including "Protect our lives so we can save yours."

"The masks are supposed to be one-time use," one nurse said, according to videos posted online. "Now, all of a sudden the CDC (Centers for Disease Control and Prevention) is saying that it's fine for us to reuse them. These choices are being made not based on science. They're being made based on need."

One resident at New York Presbyterian Hospital said they were issued with just one mask.

"This is your mask forever. You can bring it home with you. Here's how you can clean your mask," said the resident, who asked not to be named because he was not authorized to speak to the media. "It's not the people who are making these decisions that go into the patients' rooms."

Doctors are also especially concerned about a shortage of ventilators, machines that help patients breathe and are widely needed for those suffering from COVID-19, the pneumonia-like respiratory ailment caused by the highly contagious novel coronavirus.

Hospitals have also sounded the alarm about scarcities of drugs, oxygen tanks and trained staff.

By Saturday afternoon, the US number of cases stood at 115,842 with at least 1,929 deaths, according to a Reuters tally. The United States has had the most recorded cases of any country since its count of infections eclipsed those of China and Italy on Thursday.

BLACK MARKET
As shortages of key medical supplies abounded, desperate physicians and nurses were forced to take matters into their own hands.

New York-area doctors say they have had to recycle some protective gear, or even resort to bootleg suppliers.

Dr. Alexander Salerno of Salerno Medical Associates in northern New Jersey described going through a "broker" to pay $17,000 for masks and other protective equipment that should have cost about $2,500, and picking them up at an abandoned warehouse.

"You don't get any names. You get just phone numbers to text," Salerno said. "And so you agree to a term. You wire the money to a bank account. They give you a time and an address to come to."

Nurses at Mount Sinai Hospital in New York said they were locking away or hiding N95 respirator masks, surgical masks and other supplies that are prone to pilfering if left unattended.

"Masks disappear," nurse Diana Torres said. "We hide it all in drawers in front of the nurses' station."

One nurse at Westchester Medical Center, in the suburbs of the city, said colleagues have begun absconding with scarce supplies without asking, prompting better-stocked teams to lock masks, gloves and gowns in drawers and closets.

An emergency room doctor in Michigan, an emerging epicenter of the pandemic, said he was wearing one paper face mask for an entire shift due to a shortage and that hospitals in the Detroit area would soon run out of ventilators.

"We have hospital systems here in the Detroit area in Michigan who are getting to the end of their supply of ventilators and have to start telling families that they can't save their loved ones because they don't have enough equipment," the physician, Dr. Rob Davidson, said in a video posted on Twitter.

Sophia Thomas, a nurse practitioner at DePaul Community Health Center in New Orleans, where Mardi Gras celebrations late last month fueled an outbreak in Louisiana's largest city, said the numbers of coronavirus patients "have been staggering."

In the nation's second-largest city, Los Angeles Mayor Eric Garcetti said spiking cases were putting Southern California on track to match New York City's infection figures in the next week.

Jun 11: The total death toll in the US from the novel coronavirus pandemic could hit the grim figure of 200,000 by September and expecting a dramatic decrease in COVID-19 cases in the country will be a "wishful thinking , an eminent Indian-American professor has warned.

Ashish Jha, the head of Harvard's Global Health Institute, told CNN on Wednesday that he is not trying to scare people to stay at home rather urged everyone to wear masks, adhere to the social distancing rules and called for ramping up testing and tracing infrastructure.

Anybody who's expecting a dramatic decrease in cases is almost surely engaging in wishful thinking. And if it (COVID numbers) stays just flat for the next three months, we're going to hit 200,000 deaths sometime in September and that is just awful, Jha said.

Jha said the 200,000 death toll is not just a guess . Currently 800-1000 people are dying daily in America from the virus and all data suggest that the situation is going to get worse.

We're gonna have increases, but even if we assume that it's going to be flat all summer, that nothing is going to get worse... even if we pick that low number of 800 a day, that is 25,000 (deaths) a month in three and a half months. We're going to add another 88,000 people and we will hit 200,000 sometime in September, Jha said.

The United States is by far the hardest-hit country in the global pandemic, in terms of both confirmed infections and deaths.

According to data by the Johns Hopkins University, the number of coronavirus cases in the US currently is nearly two million and about 112,900 people have died in the country, the most in the world.

When asked about an improvement in states like New York, which had been the epicenter of the COVID19 pandemic in the US, Jha said while coronavirus cases are declining in New York, New Jersey, Connecticut and Massachusetts, the numbers are increasing in states such as Arizona, Florida, Texas, North and South Carolina while the country as a whole is pretty flat.

He said, people should take measures as that will help suppress the virus and ensure people could get back outside safely but he voiced concern that this was not the situation in reality.

We're not doing that and so we're going to unfortunately have another 25,000 deaths a month until September, and then it'll keep going. It's not going to magically disappear. We've got a turn around. This is not the future I want, he said.

Jha said he had expected the situation to improve in the summer months but on the contrary the numbers have continued to rise even in the warm weather.

Summer was supposed to be our better months - warmer weather, people outside, a little less transmission. This is not the time (summer) I was expecting a lot more cases. We're seeing a lot more cases, especially in states like Arizona where the numbers look really scary, he said.

Jha added that he was hopeful that maybe the summer months would give us more of a break. I think I may have been too optimistic on that.

Islamabad, Jul 3: The US embassy here in a statement on Friday said the Trump administration through the US Agency for International Development (USAID) “donated a shipment of 100 brand-new, state-of-the-art ventilators” to Pakistan.

The ventilators arrived in Karachi on July 2 and will be sent to hospitals across Pakistan.

“This donation delivers on President Donald Trump’s generous offer of these critically-needed supplies and supports Pakistan’s urgent response to the pandemic,” the embassy said.

Made in America, the ventilators are valued at about $3 million and reflect the latest in cutting-edge medical design and technology, it said.

They are compact, easily deployable, and will enable Pakistan to more effectively treat patients suffering from Covid-19.

The US-Pakistan health partnership to curb the spread of the novel coronavirus is helping to improve and expand laboratory testing, disease monitoring, case tracking, infection prevention and control and patient care, the embassy said.

The US has contributed nearly $27 million in new funding so far to this vital partnership that is growing every day. "We are also thankful for Pakistan's contribution of medical supplies to help fight coronavirus in the US," the embassy said in the statement.

Ambassador Paul Jones said, “The US stands with Pakistan in its fight against the coronavirus. These American-made ventilators will help Pakistani patients in the most acute need of medical care."

The announcement comes days after Pakistan said it had started producing locally designed ventilators.

Pakistan reported 78 more deaths from the coronavirus in the past 24 hours, raising virus-related fatalities to 4,551 while the total number of confirmed cases has increased to 221,896.

On Friday, the health authorities said 1,13,623 persons have recovered from the coronavirus, surpassing the number of active Covid-19 infections in the country for the first time.
