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.

Beijing, Jun 17: China said Wednesday it wanted to avoid further clashes with India along their border after the first deadly confrontation between the two nuclear powers in decades.

The two countries have traded blame for Monday's high-altitude brawl that left at least 20 Indian soldiers dead, with China refusing to confirm so far whether there were any casualties on its side.

Chinese foreign ministry spokesman Zhao Lijian insisted again Wednesday that it was Indian troops who illegally crossed the border and attacked the Chinese side.

This led to "a serious physical confrontation between both sides that caused deaths and injuries", Zhao said at a regular briefing, without providing more details about the casualties.

He said China urges India to "strictly restrain frontline troops, do not illegally cross the border, do not make provocative gestures, do not take any unilateral actions that will complicate the border situation".

But he added that the two sides "will continue to resolve this issue through dialogue and negotiations".

"We of course don't wish to see more clashes," Zhao said.

Beijing, Apr 17: China denied Friday it had covered up the extent of its coronavirus outbreak, as it responded to growing questions from Western powers led by the United States.

A foreign ministry spokesman acknowledged that the virus's rapid spread had contributed to undercounting that resulted in China raising its death toll earlier Friday, but he added "there has never been any concealment, and we'll never allow any concealment."

The allegations China is too close to the World Health Organization (WHO), were an attempt at "smearing" Beijing, Zhao said.

US President Donald Trump has questioned China's handling of the pandemic and whether it had been completely transparent since the virus emerged in the central city of Wuhan late last year.

On Thursday, British Foreign Secretary Dominic Raab and French President Emmanuel Macron also expressed doubts about China's virus response.

These doubts were spotlighted again on Friday when authorities in Wuhan, which has borne the brunt of Chinese deaths, abruptly raised its death toll by 50 percent -- or 1,290 deaths -- to a new total of 3,869.

That also pushed the nationwide death toll up sharply to 4,632, based on official national data released earlier in the day.

Wuhan authorities cited several reasons for the missed cases, including that the city's medical staff were overwhelmed in the early days as infections climbed, leading to "late reporting, omissions or mis-reporting".

Zhao said such miscounting was to be expected in the initial stages of a major disease outbreak.

US President Donald Trump -- under fire himself for initially denying the seriousness of the pandemic -- has accused the WHO of doing the same and being too trusting of China's assurances over the outbreak.

On Tuesday he announced a suspension of US funding to the world body.

Asked about the US allegations, Zhao defended the WHO and China.

"I think they are all smearing China and cooking up stories about China," he said, without specifying which countries he was referring to.

China has largely brought the contagion under control domestically via tough measures including the unprecedented lockdown of Wuhan and tens of millions of people in surrounding areas, but not before it spread worldwide.

London, Apr 30: The coronavirus is roiling global job markets, but the picture is not all gloomy. Finance, technology and consumer goods firms are hiring tens of thousands in the United States and other countries, according to data from Microsoft Corp's professional networking site LinkedIn.

Across seven countries in North America, Europe and Asia, healthcare providers are among the busiest recruiters given the ongoing battle against the novel coronavirus, which has killed over 200,000 people and infected over 3 million people worldwide, LinkedIn said. But lifestyle changes during lockdown are also driving demand for financial consultants, factory workers, animators and game designers, and delivery workers.

Overall, the hiring rate has plunged in the first quarter from the year-ago period, and in late April remains lower than a year ago across most countries surveyed by the platform. But the data offer a glimmer of hope with a gradual uptick in China, where the coronavirus emerged last year and which leads the world in surfacing from a months-long lockdown.

LinkedIn, with over 690 million users worldwide, counts new hires when people add a new employer to their profile. The rate is the number of new hires divided by the total number of LinkedIn members in a country.

The figures, tracked since mid-February, are not corroborated by official jobs data and do not represent the actual number of jobs in an economy. Government figures are usually released with a time-lag of several weeks.

"We are confident that our data is directionally correct in that there has been a huge decline in hiring in the U.S. and abroad," Guy Berger, principal economist at LinkedIn in California, told Reuters.

Hiring in China plummeted 50% during the height of its coronavirus crisis in mid-February from 12 months earlier. Since restrictions were eased in early April, the hiring rate has inched up, and for the week ending April 24 was 3% lower than the same period in 2019.

Hiring in the United States, United Kingdom, France and Italy - which lead the world in coronavirus-related deaths - remains hugely depressed, but is falling less rapidly than a few weeks ago as the countries pass the peak of their epidemics.

Retailers including Walmart Inc, Amazon.com Inc and Instacart have said they would hire a total of over 700,000 workers to meet a surge in demand for groceries and household essentials during the coronavirus outbreak.

Coronavirus state-wise India update: Total number of confirmed cases, deaths on April 30

Consumer goods manufacturers such as Unilever, whose products include soap and shampoo, confirmed on Wednesday it was hiring to fill 300 jobs globally, but declined to elaborate.

Nestle told Reuters it was looking to fill 5,000 full-time U.S. positions in "a variety of levels across corporate and frontline."

Fidelity Investments, a Boston-based financial services firm, said it had accelerated recruitment because of the pandemic and was looking to fill at least 2,000 full-time roles for financial consultants, software engineers and customer service staff in the United States in 2020.

Companies hiring in the United States and other countries also include Apple Inc; ByteDance, the Chinese parent of video-sharing social network TikTok; Takeda Pharmaceutical Co Ltd; and aerospace and defence company Lockheed Martin Corp. These companies did not immediately respond to requests for comment.

DIRE WARNINGS

The International Labour Organization warned on Wednesday that 1.6 billion workers, or nearly half of the global workforce, especially in the informal economy, could lose their livelihoods.

Record numbers of people have applied for U.S. jobless benefits since mid-March, and the unemployment rate is expected to soar to 16%, White House economic adviser Kevin Hasset said this week, from a 50-year low of 3.5% before the pandemic hit.

Both Italy and France, in lockdown for nearly two months, have seen hiring rates drop by around 70% from a year ago, according to LinkedIn.

Since China is ahead of other countries on the pandemic timeline, improvements there could suggest the same is in store elsewhere, Berger said. Several American states and European countries have begun allowing some non-essential businesses and schools to reopen in the hopes of restarting the economy and allowing a gradual return to normal life.

"It's still slightly early to call it a firm recovery," Berger said, referring to improving prospects in China. "We're not expecting a full recovery but rather it's an indication that parts of the economy will switch on as lockdowns are eased, at least relative to the worst point of the pandemic."
