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.

London, Apr 22: The UK government on Tuesday announced a 20 million pounds funding for a University of Oxford project working on developing a vaccine against the novel coronavirus, which is now ready for acceleration as it begins human trials from Thursday.

UK Health Secretary Matt Hancock told the daily Downing Street briefing that the Department for Health was “throwing everything” at trying to find a vaccine because it is a critical aspect of the COVID-19 pandemic fight and lifting the strict lockdown measures in place to curb its spread.

Another 22.5 million pounds is being made available to Imperial College London to support its phase-two clinical trials for them to begin the work on a very large phase three trial.

"Normally it would take years to get to this point," said Hancock.

"The UK is at the forefront of the global effort – we've put in more money than any other into the global search for a vaccine. Nothing about this is inevitable. Vaccine production is a matter of trial and error. But the UK will throw everything it has at trying to find one,” he said.

The announcement came as Britain had another major daily leap in the hospital death toll from coronavirus, up by 823 to hit 17,337 on Tuesday.

But the Cabinet minister said the government's plan to control the rapid spread of the virus and prevent the state-funded National Health Service (NHS) from being overwhelmed is working as the number of hospitalisations with COVID-19 was showing a downward trajectory.

In reference to a major issue in the last few weeks of a critical shortage of personal protective equipment (PPE) for doctors and nurses on the frontlines of COVID-19 treatment, the minister said the supply problems are being addressed by actively engaging with thousands of companies, including 159 UK manufacturers.

“We are determined to get people the PPE they need. This is a 24/7 operation, one of the biggest cross-government operation I have ever seen," said Hancock.

Washington, May 6: The Chinese Army is indulging in aggressive behaviour in the South China Sea and the Chinese Communist Party has ramped up its disinformation campaign to try to shift the blame on coronavirus and burnish its image, US Defense Secretary Mark Esper said on Tuesday.

"While the Chinese Communist Party ramps up its disinformation campaign to try to shift blame and burnish its image, we continue to see aggressive behaviour by the PLA in the South China Sea, from threatening a Philippine Navy ship to sinking a Vietnamese fishing boat and intimidating other nations from engaging in offshore oil and gas development," Esper told reporters at a Pentagon news conference.

Last week, two US Navy ships conducted freedom of navigation operations in the South China Sea to send a clear message to Beijing that America will continue to protect the freedom of navigation and commerce for all nations large and small, he said.

Many countries, Esper said, have turned inward to recover from the pandemic and in the meantime, America's strategic competitors are attempting to exploit this crisis to their benefit at the expense of others.

Responding to a question, he said the Chinese have not been transparent from the beginning on the coronavirus pandemic.

"If they had been more transparent, more open, upfront in terms of giving us access, the reporting, giving us access not to the people on the ground but to the virus they had so we could understand it, we would probably be in a far different place right now. But where we are now is this," Esper said.

China needs to allow the United States in to talk to early patients, Chinese researchers and scientists, and to have access, he added.

Instead, Esper alleged that the Chinese are trying to capitalise on this by promoting their own image that somehow, China is the good guy here.

"Despite everything they did or, more importantly, failed to do, now they want to go out and say well, here's masks. We will give you masks, provide this, or provide that, we will provide you funding. Look at all the good things we are doing," he said.

"Yet, what we know is that they provide masks, they provide supplies. In many cases, it is not good. It does not do what it is supposed to do. It is broken equipment. Also, the strings attached are enormous in many cases. So, they are telling a country you can take these masks, but please, put out publicly how good China is, how great we are doing, et cetera, et cetera," Esper said.

"So there is a number of things they are doing to try and burnish their image. That is just two of them right there," he said.

The Chinese are also doing a lot of strong-arming behind the scenes, Esper said and referred to the war of words between China and Australia. He said he plans to talk to his Australian counterpart later in the day.

"All these activities are going on. It is straight from the Chinese playbook. Once again, it is just a little bit more obvious this time with what they are doing and how they are using a combination of compelling and coercion and everything else to try and shape the narrative and burnish the image of the Chinese Communist Party," Esper said.

Shanghai, Jan 27: The death toll from a coronavirus outbreak in China rose to 81 on Monday, as the government extended the Lunar New Year holiday and more big businesses shut down or told staff to work from home in an effort to curb the spread.

Chinese Premier Li Keqiang visited the central city of Wuhan, the epicenter of the outbreak, as the government sought to signal it was responding seriously to the crisis.

The total number of confirmed cases in China rose about 30% to 2,744, about half of them in Hubei province, whose capital is Wuhan.

As worries grew around the world, Chinese-ruled Hong Kong, which has had eight confirmed cases, banned entry to people who had visited Hubei in the past 14 days. The ban did not cover Hong Kong residents.

The number of deaths from the flu-like virus in Hubei climbed to 76 from 56, health officials said, with five deaths elsewhere in China, including the southern island province of Hainan, which reported its first fatality on Monday.

While a small number of cases have been confirmed in more than 10 countries, linked to people who traveled from Wuhan, no deaths have been reported elsewhere.

Li is the most senior leader to visit Wuhan since the outbreak began. Clad in a blue protective suit and mask, he inspected efforts to contain the epidemic and spoke to patients and medical staff, the government said.

The government is extending the week-long Lunar New Year holiday by three days to February 2, in a bid to slow the spread of the virus. The Lunar New Year is usually a time for millions of people to travel, but many have had to cancel their plans because of travel curbs over the virus.

Incubation

Wuhan is already in virtual lockdown and severe limits on movement are in place in several other Chinese cities.

The city of 11 million clamped down further on Monday, announcing the suspension of visa and passport services until January 30.

Despite the curbs, the mayor of Wuhan said on Sunday that five million people had left the city for holidays and other reasons.

Images from Wuhan showing hospital corridors packed with people seeking treatment have circulated on social media, along with complaints of soaring prices for essentials such as vegetables.

Chinese leaders have urged transparency in the crisis, after public trust was eroded by the cover-up of the spread of Severe Acute Respiratory Syndrome (SARS), a coronavirus that originated in China and killed nearly 800 people globally in 2002 and 2003.

Much is not known about the newly identified coronavirus, including how easily it spreads and just how dangerous it is. It can cause pneumonia, which has been deadly in some cases.

National Health Commission minister Ma Xiaowei said on Sunday the incubation period could range from one to 14 days, and the virus was infectious during incubation, unlike SARS.

That compares with a World Health Organization (WHO) estimate of two to 10 days for the incubation period.

“Understanding the time when infected patients may transmit the virus to others is critical for control efforts,” the WHO said.

The virus is believed to have originated late last year in a Wuhan market illegally selling wildlife. It has spread to other cities, including Beijing and Shanghai, as well as more than 10 countries including France, Japan and the United States.

‘Overwhelmed’

Australia confirmed its fifth case on Monday involving a woman on the last flight out of Wuhan to Sydney before China’s travel ban.

Health minister Greg Hunt told the Australian Broadcasting Corporation (ABC) authorities aimed to get about 100 Australian children and young people out of Wuhan.

One father of two, Nathan Wang, told the ABC his wife was stuck in Wuhan with the children. “We absolutely want the children to come back, because hospitals in Wuhan are overwhelmed,” he said.

Airports around the world have stepped up screening of passengers from China, although some health experts have questioned its effectiveness.

Last week the WHO stopped short of calling the outbreak a global health emergency, but some health experts question whether China can contain the epidemic.

WHO Director-General Tedros Adhanom Ghebreyesus is due to travel to Beijing to meet officials and health experts.

Australia, France, Italy, Japan and the United States have all said they are working to evacuate citizens from Wuhan.

Some of China’s biggest companies have been affected, with hotpot restaurant chain Haidilao International Holding shutting branches nationwide from Sunday until Friday.

Gaming giant Tencent Holdings Ltd advised staff to work from home until February 7, and e-commerce firm Alibaba removed vendors’ offers of overpriced face masks from its online Taobao marketplace as prices surged.
