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, 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.

Beijing, May 24: The Chinese virology institute in the city where COVID-19 first emerged has three live strains of bat coronavirus on-site, but none match the new contagion wreaking chaos across the world, its director has said.

Scientists think COVID-19 -- which first emerged in Wuhan and has killed some 340,000 people worldwide -- originated in bats and could have been transmitted to people via another mammal.

But the director of the Wuhan Institute of Virology told state broadcaster CGTN that claims made by US President Donald Trump and others that the virus could have leaked from the facility were "pure fabrication".

"Now we have three strains of live viruses... But their highest similarity to SARS-CoV-2 only reaches 79.8 percent," she said, referring to the coronavirus strain that causes COVID-19.

US demands immediate start to WHO review

The United States called on the World Health Organisation on Friday to begin working immediately on investigating the source of the novel coronavirus, as well as its handling of the response to the pandemic.

One of their research teams, led by Professor Shi Zhengli, has been researching bat coronaviruses since 2004 and focused on the "source tracing of SARS", the strain behind another virus outbreak nearly two decades ago.

"We know that the whole genome of SARS-CoV-2 is only 80 percent similar to that of SARS. It's an obvious difference," she said.

"So, in Professor Shi's past research, they didn't pay attention to such viruses which are less similar to the SARS virus."

Conspiracy rumours that the biosafety lab was involved in the outbreak swirled online for months before Trump and US Secretary of State Mike Pompeo brought the theory into the mainstream by claiming that there is evidence the pathogen came from the institute.

The lab has said it received samples of the then-unknown virus on December 30, determined the viral genome sequence on January 2 and submitted information on the pathogen to the WHO on January 11.

Wang said in the interview that before it received samples in December, their team had never "encountered, researched or kept the virus."

"In fact, like everyone else, we didn't even know the virus existed," she said. "How could it have leaked from our lab when we never had it?"

The World Health Organization said Washington had offered no evidence to support the "speculative" claims.

In an interview with Scientific American, Shi said the SARS-CoV-2 genome sequence did not match any of the bat coronaviruses her laboratory had previously collected and studied.

Washington, Jun 16: The United States will reduce its troop strength in Germany from the nearly 52,000 at present to 25,000, President Donald Trump has said in Washington.

In an interaction with reporters at the White House on Monday, Trump attributed the move to high costs and Germany being "delinquent" in its payment to NATO.

"We have 52,000 soldiers in Germany. That's a tremendous amount of soldiers. It's a tremendous cost to the United States and Germany, as you know, is very delinquent in their payments to NATO.

"They are paying one per cent and they're supposed to be a two per cent. And then two percent is very low. It should be much more than that. So they are delinquent of billions of dollars," Trump alleged.

"So, we're putting the number down to 25,000 soldiers. We'll see what happens, but Germany has not been making payments. In addition to that, I was the one that brought it up. Everybody talks about Trump with Russia. Well, I brought this up a long time ago. Why is Germany paying Russia billions of dollars for energy and then we're supposed to protect Germany from Russia? How does that work? It doesn't work," the US president said.

US soldiers, he said, are paid well. "They live in Germany. They spend vast amounts of money in Germany. Everywhere around those bases is very prosperous for Germany. So, Germany takes. And then on top of it, they treat us very badly on trade. We have trade with the EU, Germany being the biggest member, and very, very badly on trade and we are negotiating with them on that. But right now, I'm not satisfied with the deal they want to make," Trump said.

"They've cost the United States hundreds of billions of dollars over the years on trade," he said.

The US protects them and then they take advantage of America on trade, the president said.

"So we are working on a deal with them, but it's very unfair and I would say by far, the worst abuser is Germany," he said.
