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.

Feb 26: China’s massive travel restrictions, house-to-house checks, huge isolation wards and lockdowns of entire cities bought the world valuable time to prepare for the global spread of the new virus.

But with troubling outbreaks now emerging in Italy, South Korea and Iran, and U.S. health officials warning Tuesday it’s inevitable it will spread more widely in America, the question is: Did the world use that time wisely and is it ready for a potential pandemic?

“It’s not so much a question of if this will happen anymore, but rather more a question of exactly when this will happen — and how many people in this country will have severe illness,” said Dr. Nancy Messonnier of the U.S. Centers for Disease Control and Prevention.

Some countries are putting price caps on face masks to combat price gouging, while others are using loudspeakers on trucks to keep residents informed. In the United States and many other nations, public health officials are turning to guidelines written for pandemic flu and discussing the possibility of school closures, telecommuting and canceling events.

Countries could be doing even more: training hundreds of workers to trace the virus’ spread from person to person and planning to commandeer entire hospital wards or even entire hospitals, said Dr. Bruce Aylward, the World Health Organization’s envoy to China, briefing reporters Tuesday about lessons learned by the recently returned team of international scientists he led.

“Time is everything in this disease,” Aylward said. “Days make a difference with a disease like this.”

The U.S. National Institutes of Health’s infectious disease chief, Dr. Anthony Fauci, said the world is “teetering very, very close” to a pandemic. He credits China’s response for giving other nations some breathing room.

China locked down tens of millions of its citizens and other nations imposed travel restrictions, reducing the number of people who needed health checks or quarantines outside the Asian country.

It “gave us time to really brush off our pandemic preparedness plans and get ready for the kinds of things we have to do,” Fauci said. “And we’ve actually been quite successful because the travel-related cases, we’ve been able to identify, to isolate” and to track down those they came in contact with.

With no vaccine or medicine available yet, preparations are focused on what’s called “social distancing” — limiting opportunities for people to gather and spread the virus.

That played out in Italy this week. With cases climbing, authorities cut short the popular Venice Carnival and closed down Milan’s La Scala opera house. In Japan, Prime Minister Shinzo Abe called on companies to allow employees to work from home, while the Tokyo Marathon has been restricted to elite runners and other public events have been canceled.

Is the rest of the world ready?

In Africa, three-quarters of countries have a flu pandemic plan, but most are outdated, according to authors of a modeling study published last week in The Lancet medical journal. The slightly better news is that the African nations most connected to China by air travel — Egypt, Algeria and South Africa — also have the most prepared health systems on the continent.

Elsewhere, Thailand said it would establish special clinics to examine people with flu-like symptoms to detect infections early. Sri Lanka and Laos imposed price ceilings for face masks, while India restricted the export of personal protective equipment.

India’s health ministry has been framing step-by-step instructions to deal with sustained transmissions that will be circulated to the 250,000 village councils that are the most basic unit of the country’s sprawling administration.

Vietnam is using music videos on social media to reach the public. In Malaysia, loudspeakers on trucks blare information through the streets.

In Europe, portable pods set up at United Kingdom hospitals will be used to assess people suspected of infection while keeping them apart from others. France developed a quick test for the virus and has shared it with poorer nations. German authorities are stressing “sneezing etiquette” and Russia is screening people at airports, railway stations and those riding public transportation.

In the U.S., hospitals and emergency workers for years have practiced for a possible deadly, fast-spreading flu. Those drills helped the first hospitals to treat U.S. patients suffering from COVID-19, the disease caused by the virus.

Other hospitals are paying attention. The CDC has been talking to the American Hospital Association, which in turn communicates coronavirus news daily to its nearly 5,000 member hospitals. Hospitals are reviewing infection control measures, considering using telemedicine to keep potentially infectious patients from making unnecessary trips to the hospital and conserving dwindling supplies of masks and gloves.

What’s more, the CDC has held 17 different calls reaching more than 11,000 companies and organizations, including stadiums, universities, faith leaders, retailers and large corporations. U.S. health authorities are talking to city, county and state health departments about being ready to cancel mass gathering events, close schools and take other steps.

The CDC’s Messonnier said Tuesday she had contacted her children’s school district to ask about plans for using internet-based education should schools need to close temporarily, as some did in 2009 during an outbreak of H1N1 flu. She encouraged American parents to do the same, and to ask their employers whether they’ll be able to work from home.

“We want to make sure the American public is prepared,” Messonnier said.

How prepared are U.S. hospitals?

“It depends on caseload and location. I would suspect most hospitals are prepared to handle one to two cases, but if there is ongoing local transmission with many cases, most are likely not prepared just yet for a surge of patients and the ‘worried well,’” Dr. Jennifer Lighter, a pediatric infectious diseases specialist at NYU Langone in New York, said in an email.

In the U.S., a vaccine candidate is inching closer to first-step safety studies in people, as Moderna Inc. has delivered test doses to Fauci’s NIH institute. Some other companies say they have candidates that could begin testing in a few months. Still, even if those first safety studies show no red flags, specialists believe it would take at least a year to have something ready for widespread use. That’s longer than it took in 2009, during the H1N1 flu pandemic — because that time around, scientists only had to adjust regular flu vaccines, not start from scratch.

The head of the World Health Organization, Tedros Adhanom Ghebreyesus, said the U.N. health agency’s team in China found the fatality rate between 2% and 4% in the hard-hit city of Wuhan, the virus’ epicenter, and 0.7% elsewhere.

The world is “simply not ready,” said the WHO’s Aylward. “It can get ready very fast, but the big shift has to be in the mindset.”

Aylward advised other countries to do “really practical things” now to get ready.

Among them: Do you have hundreds of workers lined up and trained to trace the contacts of infected patients, or will you be training them after a cluster pops up?

Can you take over entire hospital wards, or even entire hospitals, to isolate patients?

Are hospitals buying ventilators and checking oxygen supplies?

Countries must improve testing capacity — and instructions so health workers know which travelers should be tested as the number of affected countries rises, said Johns Hopkins University emergency response specialist Lauren Sauer. She pointed to how Canada diagnosed the first traveler from Iran arriving there with COVID-19, before many other countries even considered adding Iran to the at-risk list.

If the disease does spread globally, everyone is likely to feel it, said Nancy Foster, a vice president of the American Hospital Association. Even those who aren’t ill may need to help friends and family in isolation or have their own health appointments delayed.

“There will be a lot of people affected even if they never become ill themselves,” she said.

Paris, Aug 5: French President Emmanuel Macron on Tuesday said France will deploy a civil security detachment and several tonnes of medical equipment to Lebanon, whose capital was hit by an explosion that left over 70 people dead and thousands injured.

"Emergency doctors will also reach Beirut as soon as possible to strengthen hospitals. France is already engaged," the French President said in a tweet.

US Secretary of State Mike Pompeo, also extended his deepest condolences to all those affected by the "massive explosion at the port of Beirut."

"We are closely monitoring and stand ready to assist the people of Lebanon as they recover from this tragedy. Our team in Beirut has reported to me the extensive damage to a city and a people that I hold dear, an additional challenge in a time of already deep crisis. 

We understand that the Government of Lebanon continues to investigate its cause and look forward to the outcome of those efforts," he said in a statement.

UK Prime Minister Boris Johnson said his country is ready to provide support in any way it can.

"The pictures and videos from Beirut tonight are shocking. All of my thoughts and prayers are with those caught up in this terrible incident. The UK is ready to provide support in any way we can, including to those British nationals affected," Johnson said.

Israeli people share the pain of their Lebanese neighbours after a devastating blast in the port of Beirut and reach out to offer their aid, Israeli President Reuven Rivlin said on Tuesday.

"We share the pain of the Lebanese people and sincerely reach out to offer our aid at this difficult time," Rivlin said on Twitter.

Over 70 people have been killed while thousands of others were wounded in the massive explosion on Tuesday in Beirut which shattered buildings and caused widespread damage.

Wuhan, Feb 16: The death toll from China's coronavirus epidemic has climbed to 1,665 after 142 more people died, mostly in the worst-hit Hubei Province, and the confirmed cases jumped to 68,500, officials said on Sunday, as top WHO experts scramble to assist Beijing contain the virus spread.

China's National Health Commission confirmed 2,009 new cases across the country.

Hubei and its provincial capital Wuhan, where the virus first emerged in December, reported 1,843 of the new cases. The latest report brought the total confirmed cases in Hubei to 56,249 cases.

Of the new deaths, 139 were in Hubei, two in Sichuan, and one in Hunan, the state-run Xinhua news agency reported.

The number of new cases, however, appears to have started dropping and a top Chinese health official has said efforts to control the outbreak have reached the “most crucial stage".

The report said 9,419 infected patients had been discharged from hospital after recovery so far.

The coronavirus has posed a severe threat to the medical staff as more than 1,700 Chinese health officials have been infected by the virus while treating the patients and six of them have died.

Experts from the World Health Organisation are expected in Beijing on Sunday to join Chinese health authorities in containing the virus, which has spread to several other countries forcing them to temporarily stop tourist arrivals from China.

The health commission said a joint mission with WHO experts will pay field visits to China's three provincial-level regions to learn the effectiveness of the epidemic control measures.

One task of the mission will be to come up with standard medicine to cure the disease, according to the health commission.

Several antiviral drugs are under clinical trials and Chinese researchers have narrowed down their focus to a few existing drugs, including Chloroquine Phosphate, Favipiravir and Remdesivir, said Zhang Xinmin, director of the China National Centre for Biotechnology Development.

Experts have asked people to frequently wash hands and face, and wear masks.

Authorities have begun quarantining large quantity of bank notes and coins in the affected areas and sanitising them with UV light before releasing them back into circulation to stop the virus from spreading.
