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.

Chengdu, Jul 24: China on Friday asked the US to close down its Consulate in Chengdu in retaliation to Washington's decision to shut the Chinese Consulate in Houston.

A statement by the Chinese Foreign Ministry said China has informed the US Embassy of its decision to withdraw its consent for the establishment and operation of the US Consulate General in Chengdu.

This was in response to "unilateral" decision by the US to shut the Houston Consulate. China's decision is legitimate and necessary response to the unreasonable actions of the US, it said.

The US on Wednesday ordered the closure of the Chinese consulate in Houston, a move it said was aimed "to protect American intellectual property and private information."

Reacting strongly to the US move, Chinese Foreign Ministry spokesman Wang Wenbin termed it as an "unprecedented escalation and warned retaliatory measures.

China on Thursday said that "malicious slander" is behind an order by the US government to close its consulate in Houston, Texas, and maintained that its officials have never operated outside ordinary diplomatic norms.

Wang said the order to close the consulate violates international law and basic norms governing international relations, and seriously undermines China-US relations.

This is breaking down the bridge of friendship between the Chinese and American people, Wang said.

London: Italy on Friday recorded the most daily deaths of any country since the start of the coronavirus pandemic and Spain had its deadliest day, as British Prime Minister Boris Johnson became the first major world leader to test positive.

Italy reported 969 new deaths, Spain 769 and France 299 as Europe reeled from a crisis that has put millions at risk around the world and threatened a global economic meltdown.

In other grim milestones, AFP tallies showed a total of 300,000 cases now recorded in Europe with more than 26,000 deaths worldwide, and the United States overtook China as the country with the most infections.

Italy showed infection rates continuing a downward trend and Spain said its rate of new infections appeared to be slowing, but other countries were bracing to feel the full impact of the virus's spread.

The World Health Organization's regional director for Africa warned the continent faced a "dramatic evolution" of the pandemic, as South Africa became the latest nation to start life under lockdown and reported its first COVID-19 deaths.

Johnson, whose country has seen more than 14,000 declared coronavirus cases and 759 deaths, said he had developed mild symptoms over the previous 24 hours and was self-isolating after testing positive.

Britain's Health Secretary Matt Hancock also tested positive with mild symptoms.

Europe has suffered the brunt of the coronavirus crisis in recent weeks, with millions across the continent on lockdown and the streets of Paris, Rome and Madrid eerily empty.

In France — where nearly 2,000 people have died -- the government announced it was extending its stay-at-home order until at least April 15. While severe, the 299 new deaths it recorded on Friday was lower than the 365 reported the previous day.

The death of a 16-year-old girl from the virus has particularly shaken France, and shattered the belief of many young people that they are immune.

The girl's mother Sabine told AFP that Julie "just had a cough" at first but deteriorated quickly. She died on Wednesday, less than a week after showing her first symptoms.

"It's unbearable," Sabine said. "We were supposed to have a normal life."

Focus was also turning to the United States, where the number of known infections jumped by 18,000 on Friday, reaching more than 97,000 -- higher than both China and Italy. The US also recorded 345 deaths over the past 24 hours, with a total toll of 1,478.

In New York City, health workers are battling a surging toll of dead and infected at the US epicentre of the crisis, including an increasing number of younger patients.

"Now it's 50-year-olds, 40-year-olds, 30-year-olds," said one respiratory therapist at the Jewish Medical Center in Queens.

They "didn't listen about not going out or protecting themselves and washing their hands", he said.

- 'Afraid and lost' -

The coronavirus first emerged in China late last year before spreading globally, with more than half a million declared cases in 183 countries and territories.

Over the last six days, as many new cases have been diagnosed around the world as in the previous 80 days.

Beijing managed to contain its spread with lockdowns and quarantines and its epicentre Wuhan is in the process of easing severe movement restrictions in place for two months.

Three billion people around the world have been told to stay indoors.

In a historic first, Pope Francis performed the rarely recited "Urbi et Orbi" blessing to an empty Saint Peter's Square.

"Thick darkness has gathered over our squares, our streets and our cities; it has taken over our lives, filling everything with a deafening silence and a distressing void, that stops everything as it passes by," he said.

"We find ourselves afraid and lost," he said, describing the coronavirus as a "tempest".

Health care systems even in the most developed nations are stretched to breaking point and medical workers have been having to make difficult choices.

"If I've got five patients and only one bed, I have to choose who gets it," Sara Chinchilla, a paediatrician at a hospital near Madrid, told AFP.

The WHO's chief Tedros Adhanom Ghebreyesus said the dire lack of protective gear for frontline health workers was one of the most pressing problems in the fight to prevent deaths.

"The chronic global shortage of personal protective equipment is now one of the most urgent threats to our collective ability to save lives," he told a virtual news conference in Geneva.

Lockdowns and other measures are wreaking havoc on the global economy, with fears of a downturn worse than the Great Depression of the 1930s.

"It is clear that we have entered a recession" that will be worse than in 2009 following the global financial crisis, International Monetary Fund chief Kristalina Georgieva said Friday.

Unprecedented stimulus measures have helped markets bounce back after a brutal month, but people around the world are bracing for economic hardship.

The United States reported that 3.3 million people applied for unemployment benefits last week -- by far the highest number ever recorded.

Retail workers in particular have suffered as many countries shutter non-essential business, while airlines and the global tourism industry have been dealt devastating blows.

The fashion industry was the latest hit on Friday, with Paris men's fashion week and haute couture shows cancelled along with Milan men's fashion week.

- Armies of volunteers -

The World Tourism Organization said Friday it expected tourist arrivals to fall by 20-30 percent this year, with losses of $300 billion-450 billion in international tourism receipts.

But there have been rays of hope in the midst of the crisis.

Armed groups in Cameroon, the Philippines and Yemen have moved in recent days to reduce violence after UN Secretary General Antonio Guterres issued an appeal for ceasefires.

And armies of volunteers have emerged in many countries to bring help to the needy, with food deliveries for the elderly, free taxi rides, accommodation for health workers, and even home-sewn face masks.
