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 30: The United States will end its relationship with the World Health Organization over the body’s handling of the coronavirus pandemic, U.S. President Donald Trump said on Friday, accusing the U.N. agency of becoming a puppet of China.

The move to quit the Geneva-based body, which the United States formally joined in 1948, comes amid growing tensions between Washington and Beijing over the coronavirus outbreak. The virus first emerged in China’s Wuhan city late last year.

Speaking in the White House Rose Garden, Trump said Chinese officials “ignored their reporting obligations” to the WHO about the virus - that has killed hundreds of thousands of people globally - and pressured the agency to “mislead the world.”

“China has total control over the World Health Organization despite only paying $40 million per year compared to what the United States has been paying which is approximately $450 million a year,” he said.

Trump’s decision follows a pledge last week by Chinese President Xi Jinping to give $2 billion to the WHO over the next two years to help combat the coronavirus. The amount almost matches the WHO’s entire annual program budget for last year.

Trump last month halted funding for the 194-member organization, then in a May 18 letter gave the WHO 30 days to commit to reforms.

“Because they have failed to make the requested and greatly needed reforms, we will be today terminating our relationship with the World Health Organization and redirecting those funds to other worldwide and deserving urgent global public health needs,” Trump said on Friday.

It was not immediately clear when his decision would come into effect. A 1948 joint resolution of Congress on U.S. membership of the WHO said the country “reserves its right to withdraw from the organization on a one-year notice.”

The World Health Organization did not immediately respond to a request for comment on Trump’s announcement. It has previously denied Trump’s assertions that it promoted Chinese “disinformation” about the virus.

“It’s important to remember that the WHO is a platform for cooperation among countries,” said Donna McKay, executive director of Physicians for Human Rights. “Walking away from this critical institution in the midst of an historic pandemic will hurt people both in the United States and around the world.”

‘ABSOLUTELY CRITICAL’

The United States currently owes the WHO more than $200 million in assessed contributions, according to the WHO website. Washington also gives several hundred million dollars annually in voluntary funding tied to specific WHO programs such as polio eradication, HIV, hepatitis and tuberculosis.

Amesh A. Adalja, a senior scholar at Johns Hopkins Center for Health Security, said that in practice Trump’s decision was unlikely to change the operations of the WHO.

“From a symbolic or moral standpoint it’s the wrong type of action to be taking in the middle of a pandemic and seems to deflect responsibility for what we in the U.S. failed to do and blame the WHO,” said Adalja.

When Trump halted funding to the WHO last month, two Western diplomats said the U.S. suspension was more harmful politically to the WHO than to the agency’s current programs, which are funded for now.

The WHO is an independent international body that works with the United Nations. U.N. Secretary-General Antonio Guterres said last month that the WHO is “absolutely critical to the world’s efforts to win the war against COVID-19.”

When asked about Trump’s decision, a U.N. spokesman said: “We have consistently called for all states to support WHO.”

Trump has long scorned multilateralism as he focuses on an “America First” agenda. Since taking office, he has quit the U.N. Human Rights Council, the U.N. cultural agency, a global accord to tackle climate change and the Iran nuclear deal. He has also cut funding for the U.N. population fund and the U.N. agency that aids Palestinian refugees.

“The WHO is the world’s early warning system for infectious diseases,” said U.S. Representative Nita Lowey, a Democrat who chairs the House Committee on Appropriations. “Now, during a global pandemic that has cost over 100,000 American lives, is not the time to put the country further at risk.”

The US Commission on International Religious Freedom (USCIRF) has reprimanded the Imran Khan government for denying food aid to Hindus and Christians in Pakistan amid the coronavirus pandemic and warned that it will trigger an additional crisis due to religious discrimination.

The USCIRF is an independent federal government entity set up by the US Congress to monitor and report on religious freedom in the world.

Pakistan continues to be in the tier one of the USCIRF list of the countries whose record on religious freedom remains abysmal.

In a statement issue on Monday, the USCIRF said it was troubled by the reports of food aid being denied to Hindus and Christians in Pakistan amid pandemic.

Citing one of the examples of religious discrimination, the USCIRF said that in Karachi, the Saylani Welfare International Trust, a non-government organization set up to help the homeless and seasonal workers, has been refusing food aid to Hindus and Christians and providing it only Muslims.

Describing such actions "reprehensible", the USCIRF commissioner Anurima Bhargava said: "As COVID-19 continues to spread, vulnerable communities within Pakistan are fighting hunger and to keep their families safe and healthy. Food aid must not be denied because of one's faith."
One of the USCIRF commissioners, Johnnie Moore warned that if the Khan government continued with such policies, Pakistan would add an additional crisis.

"In a recent address by Prime Minister Khan to the international community, he highlighted that the challenge facing governments in the developing world is to save people from dying of hunger while also trying to halt the spread of COVID-19. This is a monumental task laying before many countries.

"Prime Minister Khan's government has the opportunity to lead the way but they must not leave religious minorities behind. Otherwise, they may add on top of it all one more crisis, created by religious discrimination and inter-communal strife."

The organization which makes foreign policy recommendations to the US President, the Secretary of State, and Congress, urged the Pakistani government to ensure that food aid from distributing organizations is shared equally with Hindus, Christians, and other religions minorities.

Last year, in its annual report, the USCIRF had noted that Hindus and Christians in Pakistan "face continued threats to their security and are subjected to various forms of harassment and social exclusion".

Washington, Jun 18: US Defence officials are concerned over China's use of COVID-19 situation to gain stakes in strategically important companies of United States as the impact of novel coronavirus has left several companies in dire need of capital.

Amid the pandemic, it getting hard for the defence department to keep an eye on national security and help protect smaller companies down the chain, CNN reported.

"We are paying close attention to any indicators that China is leveraging Covid-19 to take advantage of a situation where defence companies need capital more than ever," a defence official told CNN.

In April, Ellen Lord, undersecretary of defence for acquisition and sustainment said it is paying close attention to 'adversaries' against the 'economic warfare' with the United States.

"We have to be very, very careful about the focused efforts some of our adversaries have to really undergo sort of economic warfare with us, which has been going on for some time," Ellen Lord, undersecretary of defence for acquisition and sustainment was quoted as saying by CNN.

US Committee on Foreign Investment protects its interest against hostile countries gaining ownership in strategically important companies. But the pandemic is changing the definition of national security concerns to include drugs, protective gear and medical supplies.

"These are now national security needs and we probably should have been thinking about it a long time ago in terms of biowarfare that we should have a trusted industrial base or a set of trusted allies -- the UK, or NATO allies or Japan or Korea -- who are trusted in that regard," Bill Greenwalt, a former Pentagon official.

Give the threat posed by foreign acquisition, Pentagon has been offering tools to help small US businesses defend themselves against adversarial investment and conducting background checks with other government agencies to ensure transparency.

US President Donald Trump's trade adviser Peter Navarro recently told CNN if Trump wins reelection, Washington DC will likely take offshore supply chains as national security priorities.

"If we fail to do that in the face of this crisis, we will have failed this country and all future generations of Americans," Navarro said.

The US State Department has also warned US allies to "avoid economic overreliance on China" and "guard their critical infrastructure" from China's influence.

Chad P Bown, a senior fellow at the Peterson Institute for International Economics, pointed to recent China's economic coercion of Australia on the political matter saying, "this is how China operates and everybody knows it."
