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.

Naypyitaw, Jul 2: A landslide at a jade mine in northern Myanmar has killed at least 113 people, officials say, warning the death toll is likely to rise further.

The incident took place early on Thursday in the jade-rich Hpakant area of Kachin state after a bout of heavy rainfall, the Myanmar Fire Services Department said on Facebook.

"The jade miners were smothered by a wave of mud," the statement said. "A total of 113 bodies have been found so far," it added, raising the death toll from at least 50.

Photos posted on the Facebook page showed a search and rescue team wading through a valley apparently flooded by the mudslide.

'No one could help them'

Maung Khaing, a 38-year-old miner from the area, said he saw a towering pile of waste that looked on the verge of collapse and was about to take a picture when people began shouting "run, run!"

"Within a minute, all the people at the bottom [of the hill] just disappeared," he told Reuters news agency by phone.

"I feel empty in my heart. I still have goosebumps ... There were people stuck in the mud shouting for help, but no one could help them."

Tar Lin Maung, a local official with the information ministry, said authorities had recovered more than 100 bodies.

"Other bodies are in the mud. The numbers are going to rise," he told Reuters.

Fatal landslides are common in the poorly regulated mines of Hpakant, the victims often from impoverished communities who risk their lives hunting the translucent green gemstone.

The government of Myanmar leader Aung San Suu Kyi pledged to clean up the industry when it took power in 2016, but activists say little has changed.

Official sales of jade in Myanmar were worth $750.4m in 2016-2017, according to data published by the government as part of the Extractive Industries Transparency Initiative.

But experts believe the true value of the industry, which mainly exports to China, is much larger.

Northern Myanmar's abundant natural resources - including jade, timber, gold and amber - have also helped finance both sides of a decades-long conflict between ethnic Kachin and the military.

The fight to control the mines and the revenues they bring frequently traps local civilians in the middle.

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.

United Nations, Jun 19: Half of the world's children -- one billion every year -- are affected by physical, sexual or psychological violence, suffering injuries and death because countries have failed to follow established strategies to protect them, the first report of its kind from the UN has said, with experts noting that the coronavirus-related lockdowns have left far too many youngsters stuck with their abusers.

While nearly all countries (88 per cent) have laws in place to protect minors, less than half (47 per cent) say they strongly enforce them, said the Global Status Report on Preventing Violence Against Children 2020 launched on Thursday.

Because countries have failed to follow established strategies to protect children, about one billion are affected each year by physical, sexual or psychological violence, it said.

"There is never any excuse for violence against children," WHO Director-General Tedros Adhanom Ghebreyesus said.

"We have evidence-based tools to prevent it, which we urge all countries to implement. Protecting the health and well-being of children is central to protecting our collective health and well-being, now and for the future," he said.

The report -- launched by the World Health Organisation, the UNICEF, the UNESCO, the Special Representative of the UN Secretary-General on Violence against Children and the End Violence Partnership -- charted progress in 155 countries against the "INSPIRE" framework, a set of seven strategies for preventing and responding to violence against children.

The report signaled a clear need in all countries to scale up efforts to implement them. It included the first ever global homicide estimates specifically for children under 18 years of age -- previous estimates were based on data that included 18 to 19-year olds.

According to the findings, in 2017, around 40,000 children were victims of homicide.

"Violence against children has always been pervasive, and now things could be getting much worse," UNICEF Executive Director Henrietta Fore said.

"Lockdowns, school closures and movement restrictions have left far too many children stuck with their abusers, without the safe space that school would normally offer. It is urgent to scale up efforts to protect children during these times and beyond, including by designating social service workers as essential and strengthening child helplines," she said.

UNESCO Director-General Audrey Azoulay said during the COVID-19 pandemic, and the related school closures, "we have seen a rise in violence and hate online – and this includes bullying".

"Now, as schools begin to re-open, children are expressing their fears about going back to school. It is our collective responsibility to ensure that schools are safe environments for all children. We need to think and act collectively to stop violence at school and in our societies at large," Azoulay said.

Stay-at-home measures including school closures have limited the usual sources of support for families and individuals such as friends, extended family or professionals.

This further erodes victims’ ability to successfully cope with crises and the new routines of daily life. Spikes in calls to helplines for child abuse and intimate partner violence have been observed, the report said.

While online communities have become central to maintain many children's learning, support and play, an increase in harmful online behaviors including cyberbullying, risky online behavior and sexual exploitation have been identified.

“Whilst this report was being finalised, confinement measures and the disrupted provision of already limited child protection services exacerbated the vulnerability of children to various forms of violence," said Najat Maalla M’jid, Special Representative of the UN Secretary-General on Violence against Children.

Of the INSPIRE strategies, only access to schools through enrolment showed the most progress with 54 per cent of the countries reporting that a sufficient number of children in need were being reached in this way.

Between 32 per cent and 37 per cent of the countries considered that victims of violence could access support services, while 26 per cent of the countries provided programmes on parent and caregiver support; 21 per cent of the countries had programmes to change harmful norms; and 15 per cent of the countries had modifications to provide safe physical environments for children, the report said.

Although a majority of countries (83 per cent) have national data on violence against children, only 21 per cent used these to set baselines and national targets to prevent and respond to violence against children, it added.

The report said about 80 per cent of countries have national plans of action and policies but only one-fifth have plans that are fully funded or have measurable targets. A lack of funding combined with inadequate professional capacity are likely contributing factors and a reason why implementation has been slow.

"Ending violence against children is the right thing to do, a smart investment to make - and it's possible. We can and must create a world where every child can thrive," Howard Taylor of the End Violence Partnership said.
