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.

Washington, May 12: The US Federal Bureau of Investigation and cybersecurity experts believe Chinese hackers are trying to steal research on developing a vaccine against coronavirus, two newspapers reported Monday.

The FBI and Department of Homeland Security are planning to release a warning about the Chinese hacking as governments and private firms race to develop a vaccine for COVID-19, the Wall Street Journal and New York Times reported.

The hackers are also targeting information and intellectual property on treatments and testing for COVID-19.

US officials alleged that the hackers are linked to the Chinese government, the reports say.

The official warning could come within days.

In Beijing Foreign Affairs ministry spokesman Zhao Lijian rejected the allegation, saying China firmly opposes all cyber attacks.

"We are leading the world in COVID-19 treatment and vaccine research. It is immoral to target China with rumors and slanders in the absence of any evidence," Zhao said.

Asked about the reports, President Donald Trump did not confirm them, but said: "What else is new with China? What else is new? Tell me. I'm not happy with China."

"We're watching it very closely," he added.

A US warning would add to a series of alerts and reports accusing government-backed hackers in Iran, North Korea, Russia and China of malicious activity related to the pandemic, from pumping out false news to targeting workers and scientists.

The New York Times said it could be a prelude to officially-sanctioned counterattacks by US agencies involved in cyber warfare, including the Pentagon's Cyber Command and the National Security Agency.

Last week in a joint message Britain and the United States warned of a rise in cyber attacks against health professionals involved in the coronavirus response by organised criminals "often linked with other state actors."

Britain's National Cyber Security Centre and the US Cybersecurity and Infrastructure Security Agency said they had detected large-scale "password spraying" tactics -- hackers trying to access accounts through commonly used passwords -- aimed at healthcare bodies and medical research organisations.

United Nations, May 7: An average of 80,000 COVID-19 cases were reported each day in April to the World Health Organization, the top UN health agency has said, noting that South Asian nations like India and Bangladesh are seeing a spike in the infections while the numbers are declining in regions such as Western Europe.

WHO Director-General Tedros Adhanom Ghebreyesus said on Wednesday that countries must also be able to manage any risk of the disease being imported into their territories, and communities should be fully educated to adjust to what will be a "new norm".

He said as the countries press forward in the common fight against COVID-19, they should also lay the groundwork for resilient health systems globally.

"More than 3.5 million cases of COVID-19 and almost 250,000 deaths have now been reported to the WHO. Since the beginning of April, an average of around 80,000 new cases have been reported to the WHO every day," Ghebreyesus said in Geneva yesterday.

Asserting that the virus cases were not just numbers, he said: "every single case is a mother, a father, a son, a daughter, a brother, sister or friend".

He said while the numbers are declining in Western Europe, more cases are being reported every day from Eastern Europe, Africa, South-East Asia, the Eastern Mediterranean and the Americas. Even within regions and within countries, there are divergent trends, the agency added.

While some countries are reporting an increase in COVID-19 cases over time, many have seen caseloads rise because they have ramped up testing, the WHO official said.

"We've also seen in Europe and Western Europe a fundamental decrease in the number of cases, but we have seen an associated increase in the number of cases reported in places like the Russian Federation. Southeast, the Western Pacific areas are relatively on the downward trend like Korea and others, but then we do see in South Asia, in places like Bangladesh, in India, some trends towards increase.

"So it's very difficult to say that any particular region is improving or (not improving). There are individual countries within each region that are having difficulties getting on top of this disease and I am particularly concerned about those countries that have (an) ongoing humanitarian crisis," WHO's Executive Director Michael Ryan said.

The death toll due to COVID-19 in India rose to 1,783 while the number of cases climbed to 52,952 on Thursday, registering an increase of 89 deaths and 3,561 cases in the last 24 hours, the Union Health Ministry said.

The number of active COVID-19 cases stood at 35,902 while 15,266 people have recovered, it said.

Noting that while seeing an increase in the number of cases is not good in terms of transmission, WHO's Emerging Diseases and Zoonoses Unit head Maria Van Kerkhove said: "but I don't want to equate that with something (being) wrong".

"I want to equate that with countries are working very hard to increase their ability to find the virus, to find people with the virus, to have testing in place to identify who has COVID-19, and putting into place what they need to do to care for those patients," Kerkhove said.

With more countries considering easing restrictions implemented to curb the spread of the coronavirus, the WHO has again reminded the authorities of the need to maintain vigilance.

"The risk of returning to lockdown remains very real if countries do not manage the transition extremely carefully, and in a phased approach," Ghebreyesus said.

He urged countries to consider the UN agency's six criteria for lifting stay-at-home measures.

That advice includes ensuring surveillance is strong, cases are declining and transmission is controlled. Health systems also must be able to detect, isolate, test and treat cases, and to trace all contacts.

Additionally, the risk of outbreak in settings such as health facilities and nursing homes needs to be minimised, while schools, workplaces and other public locations should have preventive measures in place.

"The COVID-19 pandemic will eventually recede, but there can be no going back to business as usual. We cannot continue to rush to fund panic but let preparedness go by the wayside," he said.

He said the crisis has highlighted the importance of strong national health systems as the foundation of global health security: not only against pandemics but also against the multitude of health threats that people across the world face every day.

"If we learn anything from COVID-19, it must be that investing in health now will save lives later," Ghebreyesus said.

While the world currently spends around USD 7.5 trillion on health annually, the WHO believes the best investments are in promoting health and preventing disease.

"Prevention is not only better than cure, it's cheaper, and the smartest thing to do," he said.

The deadly coronavirus, which originated from the Chinese city of Wuhan in December last year, has infected over 3.7 million people and killed 263,831 people globally, according to a tally by Johns Hopkins University.

Beijing, Jan 24: As China stepped up measures to control the spread of coronavirus, locking down Wuhan and Huanggang cities in the Hubei province where several Indians live, the Indian Embassy here has set up hotlines for their assistance.

Chinese officials assured all assistance, including food supply, to the Indians who stayed put in the province, the Indian Embassy here said in a press release on Thursday.

Wuhan and its surrounding area became the epicentre of the coronavirus outbreak as the confirmed cases climbed to over 600 mostly from the city and the province with 17 deaths so far.

China has virtually sealed Wuhan and Huanggang cities, halting all public transport, including flight services, and advised people to stay at home and follow the precautions. The two cities put together have a population of over 17 million people.

Chinese officials said the measures have been taken to prevent the spread of the virus to other cities and the world.

Concerns arose for India too as about 700 Indian students, mostly studying medicine in different Chinese universities, resided in Wuhan and its neighbouring areas.

While many of them were believed to have left home for the Chinese New Year holidays, others remained in the city to complete their academic work. However, the exact number is not yet known.

“The Embassy of India has been receiving queries from Indians in Hubei province as well as their relatives in India in connection with the evolving situation of coronavirus infection in China,” the embassy press release said.

The embassy is in touch with relevant Chinese authorities in Beijing and Wuhan as well as Indians in Hubei Province, especially in Wuhan, it said.

“We are closely monitoring the evolving situation in China, including the advisories issued by the World Health Organisation (WHO),” the embassy said.

According to the embassy, Chinese authorities have assured all assistance to residents of Wuhan, including food supply.

“At present, it is reported that supermarkets (particularly those that are government-run) and e-commerce services, including food delivery, continue to remain operational in Wuhan,” it said.

The embassy has started two hotlines for those who wish to get in touch with the Mission in this regard in the following phone numbers:              +8618612083629 and +8618612083617.

“All are advised to also keep track of the embassy's social media accounts (Twitter:@EoIBeijing; Facebook: India in China) for updates on this evolving situation,” the release said.

Meanwhile, the Chinese Foreign ministry said all assistance would be provided to consular officials of the foreign missions to ensure the safety of the foreigners in the country.

Asked whether China would consider any request from the respective countries to move their citizens out of Wuhan, Chinese Foreign Ministry spokesman Geng Shuang said, “We always help foreign consular officials in China in their official jobs, we offer them all the assistance and convenience necessary and we work to guarantee foreign citizens' legitimate rights and interest in China.”

He said while specific detailed would be provided by local officials, China in principle, has always handled issues according to domestic laws, international laws and bilateral consular agreements.
