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/Zurich, Mar 4: China has approved the use of Swiss drugmaker Roche's anti-inflammation drug Actemra for patients who develop severe complications from the coronavirus as it urgently hunts for new ways to combat the deadly infection that is spreading worldwide.

China is hoping that some older drugs could stop severe cytokine release syndrome (CRS), or cytokine storms, an overreaction of the immune system which is considered a major factor behind catastrophic organ failure and death in some coronavirus patients.

Actemra, a biologic drug approved in 2010 in the United States for rheumatoid arthritis (RA), inhibits high Interleukin 6 (IL-6) protein levels that drive some inflammatory diseases.

China's National Health Commission said in treatment guidelines published online on Wednesday that Actemra can now be used to treat coronavirus patients with serious lung damage and high IL-6 levels.

Separately, researchers in the country are testing Actemra, known generically as tocilizumab, in a clinical trial expected to include 188 coronavirus patients and running until May 10.

Roche, which donated 14 million yuan ($2.02 million) worth of Actemra during February, said the trial was initiated independently by a third party with the aim of exploring the efficacy and safety of the drug in coronavirus patients with CRS.

It added that there was currently no published clinical trial data on the drug's safety or efficacy against the virus.

More than 3,000 people have died and 93,000 have been infected by the novel coronavirus thought to have originated in Wuhan, China, before spreading to around 90 countries including the United States, Italy, Switzerland, France and Germany.

The Swiss company, for which China is its No. 2 market behind the United States, also makes diagnostic gear to detect the coronavirus.

Since Actemra's approval a decade ago, it has become a go-to drug against other inflammatory conditions, including cytokine storms in cancer patients receiving cell therapies from Novartis and Gilead Sciences.

In 2012 it helped save the life of a young U.S. girl, the first child to be treated for leukaemia with Novatis' Kymriah, from a post-treatment rush of IL-6.

Priced at between $20-30,000 annually for RA according to SSR Health, Roche's medicine is also used for rare juvenile arthritis and giant cell arteritis, or inflammation of the blood vessels.

Beijing, Feb 3: The first batch of patients arrived on Monday at a specialised hospital built in just 10 days as part of China's intensive efforts to fight a new virus.

Huoshenshan Hospital and a second facility with 1,500 beds that's due to open this week were built by construction crews who are working around the clock in Wuhan, the city in central China where the outbreak was first detected in December.

The Wuhan treatment centres mark the second time Chinese leaders have responded to a new disease by building specialised hospitals almost overnight. As severe acute respiratory syndrome, or SARS, spread in 2003, a facility in Beijing for patients with that viral disease was constructed in a week.

The first batch of patients arrived at the Huoshenshan Hospital at 10 am on Monday, according to state media. The reports gave no details of the patients' identities or conditions.

The ruling Communist Party's military wing, the People's Liberation Army, sent 1,400 doctors, nurses and other personnel to staff the Wuhan hospital, the official Xinhua News Agency said. The government said earlier some have experience fighting SARS and other outbreaks.

Authorities have cut most road, rail and air access to Wuhan and surrounding cities, isolating some 50 million people, in efforts to contain the viral outbreak that has sickened more than 17,000 and killed more than 360 people.

The Huoshenshan Hospital was built by a 7,000-member crew of carpenters, plumbers, electricians and other specialists, according to the Xinhua News Agency.               Photos in state media showed workers in winter clothing, safety helmets and the surgical-style masks worn by millions of Chinese in an attempt to avoid contracting the virus.

About half of the two-storey, 600,000-square-foot building is isolation wards, according to the government newspaper Yangtze Daily. It has 30 intensive care units.

Doctors can talk with outside experts over a video system that links them to Beijing's PLA General Hospital, according to the Yangtze Daily. It said the system was installed in less than 12 hours by a 20-member "commando team" from Wuhan Telecom Ltd.

The building has specialised ventilation systems and double-sided cabinets that connect patient rooms to hallways and allow hospital staff to deliver supplies without entering the rooms.

The hospital received a donation of "medical robots" from a Chinese company for use in delivering medicines and carrying test samples, according to the Shanghai newspaper The Paper.

In other cities, the government has designated hospitals to handle cases of the new virus.

In Beijing, the Xiaotangshan Hospital built in 2003 for SARS is being renovated by construction workers. The government has yet to say whether it might be used for patients with the new disease.

Washington DC, May 19: US President Donald Trump has threatened to permanently halt funding for the World Health Organisation (WHO) if it did not commit to improvements within 30 days, and to reconsider the membership of the United States in the global health body.

On Monday, Trump wrote a letter to WHO Director-General Tedros Ghebreyesus that read, "If WHO doesn't commit to major substantive improvements within the next 30 days, I will make my temporary freeze of US funding to WHO permanent and reconsider our membership in the organisation."

Trump had temporarily suspended US' contribution to the WHO last month, accusing it of promoting China's "disinformation" about the coronavirus outbreak, although WHO officials denied the accusation and Beijing said that it was transparent and open.

"The only way forward for the WHO is if it can actually demonstrate independence from China. My administration has already started discussions with you on how to reform the organisation. But action is needed quickly. 

We do not have time to waste," Trump said in the letter.

"I cannot allow American taxpayer dollars to continue to finance an organisation that, in its present state, is so clearly not serving America's interests," he added.

On Monday, the WHO said that an independent review of the global coronavirus response would begin at the earliest and it received backing from China, where the virus was first discovered.
