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.

Madrid, Apr 4: Spain recorded a second successive daily drop in coronavirus-related deaths with 809 fatalities, official figures showed Saturday.

The total number of deaths in Spain now stands at 11,744, second only to Italy. A record 950 people died on Thursday.

The number of new cases also slowed at 7,026, taking the total to 124,736.

Recoveries over the last 24 hours stood at 3,706, taking that total to 34,219.

The Madrid region was the worst affected accounting for 40 percent of the deaths, 4,723, and 29 percent of the cases at 36,249. The northeastern region of Catalonia was in second place with 2,508 deaths.

Prime Minister Pedro Sanchez is due to decide whether to prolong the emergency measures and confinement declared on March 14 for another two weeks in order to get on top of the outbreak.

Langkawi, Jan 20: Malaysia will not take retaliatory trade action against India over its boycott of palm oil purchases amid a political row between the two countries, Prime Minister Mahathir Mohamad said on Monday.

India, the world’s largest edible oil buyer, this month effectively halted imports from its largest supplier and the world’s second-biggest producer in response to comments from Mahathir attacking India’s domestic policies.

“We are too small to take retaliatory action,” Mahathir told reporters in Langkawi, a resort island off the western coast of Malaysia. “We have to find ways and means to overcome that,” he added.

The 94-year-old premier of Muslim-majority Malaysia has criticised New Delhi’s new religion-based citizenship law and also accused India of invading the disputed region of Kashmir.

Mahathir again criticised India’s citizenship law on Monday, saying he believed it was “grossly unfair”.

India has been Malaysia’s largest palm oil market for the past five years, presenting the Southeast Asian country with a major challenge in finding new buyers for its palm oil.

Benchmark Malaysian palm futures fell nearly 10% last week, their biggest weekly decline in more than 11 years.

New Delhi is also unhappy with Malaysia’s refusal to revoke permanent resident status for controversial Indian Islamic preacher Zakir Naik, who has lived in Malaysia for about three years and faces charges of money laundering and hate speech in India.

Mahathir said even if the Indian government guarantees a fair trial, Naik faces the real threat of vigilante action and that Malaysia will only relocate the preacher if it can find a third country where he would be safe.

“If we can find a place for him, we will send him out.”

Istanbul, Jul 11: Turkish President Recep Tayyip Erdogan announced Friday that the Hagia Sophia, one of the architectural wonders of the world, would be reopened for Muslim worship, sparking fury in the Christian community and neighbouring Greece.

His declaration came after a top Turkish court revoked the sixth-century Byzantine monument's status as a museum, clearing the way for it to be turned back into a mosque.

The UNESCO World Heritage site in historic Istanbul, a magnet for tourists worldwide, was first constructed as a cathedral in the Christian Byzantine Empire but was converted into a mosque after the Ottoman conquest of Constantinople in 1453.

The Council of State, Turkey's highest administrative court, unanimously cancelled a 1934 cabinet decision to turn it into a museum and said Hagia Sophia was registered as a mosque in its property deeds.

The landmark ruling could inflame tensions not just with the West and Turkey's historic foe Greece but also Russia, with which Erdogan has forged an increasingly close partnership in recent years.

'Millions of Christians not heard'

Greece swiftly branded the move by Muslim-majority Turkey an "open provocation to the civilised world".

"The nationalism displayed by Erdogan... takes his country back six centuries," Culture Minister Lina Mendoni said in a statement.

The Russian Orthodox Church was equally scathing.

"The concern of millions of Christians were not heard," Church spokesman Vladimir Legoida told Interfax news agency.

The decision "shows that all pleas regarding the need to handle the situation extremely delicately were ignored," he said.

UNESCO chief Audrey Azoulay said she "deeply regrets" the decision made without prior dialogue with the UN's cultural agency.

The move was also condemned by the US Commission on International Religious Freedom, which said it was an "unequivocal politicisation" of the monument.

Hagia Sophia, which stands opposite the impressive Sultanahmet Mosque -- often called the Blue Mosque, has been a museum since 1935 and open to believers of all faiths.

Transforming it from a mosque was a key reform under the new republic born out of the ashes of the Ottoman Empire.

Sharing a presidential decree which named Hagia Sophia as a "mosque", Erdogan announced its administration would be handed over to Turkey's religious affairs directorate known as Diyanet.

"May we be blessed," he commented. The decree was published on the official gazette.

Erdogan has in recent years placed great emphasis on the battles which resulted in the defeat of Byzantium by the Ottomans, with lavish celebrations held every year to mark the conquest.

Muslim clerics have occasionally recited prayers in the museum on key anniversaries or religious holidays.

"The decision is intended to score points with Erdogan's pious and nationalist constituents," said Anthony Skinner of the risk assessment firm Verisk Maplecroft.

"Hagia Sophia is arguably the most conspicuous symbol of Turkey's Ottoman past -- one which Erdogan is leveraging to strengthen his base while snubbing domestic and foreign rivals," he told AFP.

'Chains broken'

A few hundred Turks carrying Turkish flags gathered outside Hagia Sophia shouting "Chains broken, Hagia Sophia reopened".

Police heightened security measures around the building, according to AFP journalists.

"It's been a dream since we were kids," said Erdal Gencler, an Istanbul resident.

"(Hagia Sophia) finds its true purpose again. We are very excited, proud, and hopeful that there will be beautiful services here," he added.

Fatma, a woman with tearful eyes, said: "Of course I am crying. (Hagia Sophia) belongs to us."

Ahead of the court decision, Justice Minister Abdulhamit Gul shared a picture of Hagia Sophia on his official Twitter account, with a message: "Have a good Friday."

Finance Minister Berat Albayrak, Erdogan's son-in-law, tweeted that Hagia Sophia would be reopened to Muslim worship "sooner or later", referring to a quote from Turkish poet Necip Fazil Kisakurek.

The Council of State had on July 2 debated the case brought by a Turkish group -- the Association for the Protection of Historic Monuments and the Environment, which demanded Hagia Sophia be reopened for Muslim prayers.

Since 2005, there have been several attempts to change the building's status. In 2018, the Constitutional Court rejected one application.

Despite occasional protests outside the site by Islamic groups, Turkish authorities had until now kept the building as a museum.
