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.

Dubai/Washington, Jan 7: Iran's Supreme Leader Ayatollah Ali Khamenei wept in grief with hundreds of thousands of mourners thronging Tehran's streets on Monday for the funeral of military commander Qassem Soleimani, killed by a U.S. drone on U.S. President Donald Trump's orders.

The coffins of General Qassem Soleimani and Iraqi militia leader Abu Mahdi al-Muhandis, who also died in Friday's attack in Baghdad, were draped in their national flags and passed from hand to hand over the heads of mourners in central Tehran.

Responding to Trump's threats to hit 52 Iranian sites if Tehran retaliates for the drone strike, Iran's President Hassan Rouhani pointedly wrote on Twitter: "Never threaten the Iranian nation." And Soleimani's successor vowed to expel U.S. forces from the Middle East in revenge.

Khamenei, 80, led prayers at the funeral, pausing as his voice cracked with emotion. Soleimani, 62, was a national hero in Iran, even to many who do not consider themselves supporters of Iran's clerical rulers.

Aerial footage showed people, many clad in black, packing thoroughfares and side streets in the Iranian capital, chanting "Death to America!" - a show of national unity after anti-government protests in November in which many demonstrators were killed.

The crowd, which state media said numbered in the millions, recalled the masses of people that gathered in 1989 for the funeral of the Islamic Republic's founder, Ayatollah Ruhollah Khomeini. Soleimani, architect of Iran's drive to extend its influence across the Middle East, was widely seen as Iran's second most powerful figure behind Khamenei.

His killing of Soleimani has prompted concern around the world that a broader regional conflict could flare.

Trump on Saturday vowed to strike 52 Iranian targets, including cultural sites, if Iran retaliates with attacks on Americans or U.S. assets, and stood by his threat on Sunday, though American officials sought to downplay his reference to cultural targets. The 52 figure, Trump noted, matched the number of U.S. Embassy hostages held for 444 days after the 1979 Iranian Revolution.

Rouhani, regarded as a moderate, responded to Trump on Twitter.

"Those who refer to the number 52 should also remember the number 290. #IR655," Rouhani wrote, referring to the 1988 shooting down of an Iranian airline by a U.S. warship in which 290 were killed.

Trump also took to Twitter to reiterate the White House stance that "Iran will never have a nuclear weapon" but gave no other details.

'ACTIONS WILL BE TAKEN'

General Esmail Ghaani, Soleimani's successor as commander of the Quds Force, the elite unit of Iran's Revolutionary Guards charged with overseas operations, promised to "continue martyr Soleimani's cause as firmly as before with the help of God, and in return for his martyrdom we aim to rid the region of America."

"God the Almighty has promised to take martyr Soleimani's revenge," he told state television. "Certainly, actions will be taken."

Other political and military leaders have made similar, unspecific threats. Iran, which lies at the mouth of the key Gulf oil shipping route, has a range of proxy forces in the region through which it could act.

Iran's demand for U.S. forces to withdraw from the region gained traction on Sunday when Iraq's parliament passed a resolution calling for all foreign troops to leave the country.

Iraqi caretaker Prime Minister Abdel Abdul Mahdi told the U.S. ambassador to Baghdad on Monday that both nations needed to implement the resolution, the premier's office said in a statement. It did not give a timeline.

The United States has about 5,000 troops in Iraq.

Soleimani built a network of proxy militia that formed a crescent of influence - and a direct challenge to the United States and its regional allies led by Saudi Arabia - stretching from Lebanon through Syria and Iraq to Iran. Outside the crescent, Iran nurtured allied Palestinian and Yemeni groups.

He notably mobilised Shi'ite Muslim militia forces in Iraq that helped to crush ISIS, the Sunni militant group that had seized control of swathes of Syria and Iraq in 2014.

Washington, however, blames Soleimani for attacks on U.S. forces and their allies.

The funeral moves to Soleimani's southern home city of Kerman on Tuesday. Zeinab Soleimani, his daughter, told mourners in Tehran that the United States would face a "dark day" for her father's death, adding, "Crazy Trump, don't think that everything is over with my father's martyrdom."

NUCLEAR DEAL

Iran stoked tensions on Sunday by dropping all limitations on its uranium enrichment, another step back from commitments under a landmark deal with major powers in 2015 to curtail its nuclear programme that Trump abandoned in 2018.

In response, European signatories may launch a dispute resolution process against Iran this week that could lead to a renewal of the United Nations sanctions that were lifted as part of the deal, European diplomats said on Monday.

Diplomats said France, Britain and Germany could make a decision ahead of an EU foreign ministers' meeting on Friday that would assess whether there were any ways to salvage the deal.

After quitting the deal, the United States imposed new sanctions on Iran, saying it wanted to halt Iranian oil exports, the main source of government revenues. Iran's economy has been in freefall as the currency has plunged.

Trump adviser Kellyanne Conway said on Monday that he was still confident he could renegotiate a new nuclear agreement "if Iran wants to start behaving like a normal country."

Tehran has said Washington must return to the existing nuclear pact and lift sanctions before any talks can take place.

The United States advised American citizens in Israel and the Palestinian territories to be vigilant, citing the risk of rocket fire amid heightened tensions. As a U.S. ally against Iran, Israel is concerned about possible rocket attacks from Gaza, ruled by Iranian-backed Palestinian Islamists, or major Iran proxy Hezbollah in Lebanon.

Democratic critics of Trump have said the Republican president was reckless in authorising the strike, with some saying his threat to hit cultural sites amounted to a vow to commit war crimes. Trump also threatened sanctions against Iraq and said Baghdad would have to pay Washington for an air base in Iraq if U.S. troops were required to leave.

Islamabad, Apr 26: Pakistan Prime Minister Imran Khan has been trumped by the country's powerful military yet again, this time over his government's inadequate steps and its poor response in curbing the coronavirus outbreak in the country, even as cases soared over 12,500.

In his address to the nation on March 22, Khan explained the reasons for not imposing a countrywide lockdown, asserting that millions would lose their jobs and affect families, who are below the poverty line, struggling to find enough food to eat. However, less than 24 hours later, Pakistan Army spokesperson Major General Babar Iftikhar announced the implementation of lockdown in the country having a population of over 200 million, contradicting the statements made by Imran Khan.

As lockdown was imposed, the military has deployed troops across Pakistan and is orchestrating the COVID-19 response through the National Core Committee, a body set up to coordinate policy between the national and provincial governments.

"The government left a big gap in its handling of the coronavirus. The army has tried to fill that gap, there was no choice," an unnamed retired general was quoted by Financial Times as saying.

The virus crisis in Pakistan has once again made things crystal clear about who is calling the shots -- the military, widely believed to bring Imran Khan to power in 2018.

The armymen have taken over the COVID-19 crisis as an opportunity to prove their competency in contrast to Imran Khan, who was mocked after urging youth to come forward and join Corona Relief Tigers Force, a volunteer body to wage "jihad" against the virus.

According to analysts, the military's seizure of the coronavirus response marks yet another policy failure for Imran Khan in the eyes of the generals, as per the Financial Times report.

The 67-year-old cricketer-turned-politician has repeatedly failed to gain international traction over the Kashmir issue and has struggled to convince the Financial Action Task Force (FATF) in getting his country removed from 'grey list' for terror funding.

In times of emergency, one has to take clear decisions and take them through. You can't dither. The whole world is advising strong lockdown. If the prime minister does not show that he is decisive, somebody else will," said Nafisa Shah, a Member of Parliament from the opposition Pakistan Peoples Party (PPP).

Even after the lockdown was imposed, Imran Khan continued to question the need for its implementation, raising eyebrows over the country's response in tackling the virus, as cases continue to rise. This comes even as such drastic measures are in place in many countries across the world, including neighbouring India.

According to The Dawn, the country has 12,657 confirmed cases of COVID-19, which includes 2,755 recoveries and 265 deaths. Punjab has the highest number of cases -- 5,326 --, followed by 4,232 in Sindh.

However, experts suggest that the actual numbers could be more given the low testing rates and inadequate supply of testing kits.

Doctors and nurses across the country have staged protests over the lack of personal protective equipment, as increasing numbers of health workers contract COVID-19.

"Because of the lack of resources, there is chaos among the doctors and healthcare workers. They know people are dying, they know the severity of the illness and they have to work without PPE," Shoaib Hasan Tarar, a doctor working in Rawalpindi, was quoted as saying.

As the coronavirus crisis continues to ravage Pakistan, the country's overwhelming health infrastructure has put a toll on its already floundering economy. The IMF said that the GDP will shrink 1.5 per cent in 2020. The cash-strapped nation is set to be the first major emerging economy to apply to a G-20 initiative to request debt repayment relief, according to Financial Times.

In early March, Pakistan saw a surge in coronavirus cases, when infected pilgrims and workers crossed the border from Qom, a religious city in Iran, which is a hotspot.

Pakistan's limited resources were exposed when quarantined pilgrims agitated against unhealthy conditions at Taftan camp on Pakistan-Iran border, where five people were living in a tent with no access to toilets.

While the lockdown is in place, authorities have been confronted by hardline clerics who have defied social distancing terms and downplayed the threat of the virus. During Friday prayers every week, worshippers violate the restrictions by gathering at various mosques.

Last week, Islamabad inked an agreement allowing mosques to stay open for Ramzan. It stipulated that people should follow 20 rules, including maintaining a six feet distance from each other.

"There is little consistency in terms of how the lockdown is being approached. Coronavirus has shown the disconnect between the national government, regional governments and the military. Imran Khan has been left behind as the cheerleader for keeping Pakistan's morale high. I think people are starting to ask, 'How long is he going to last?'", said Sajjan Gohel, South Asia expert and guest teacher at the London School of Economics.
