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.

Kabul, Jun 12: A blast in a mosque during Friday prayers in the western part of capital Kabul has killed at least four people and wounded many more, Afghanistan's interior ministry said.

"Explosives placed inside the Sher Shah Suri Mosque exploded during Friday prayers," said a statement issued by the ministry, which added that the mosque's prayer leader Mofleh Frotan was among those killed.

Interior ministry spokesman Tariq Arian said police have cordoned off the area and helped move the wounded to ambulances and nearby hospitals.

No group immediately claimed responsibility for the attack but a mosque attack earlier this month was claimed by an ISIL (or ISIS) group affiliate, headquartered in eastern Afghanistan's Nangarhar province.

"Interestingly, every time you have the peace process gaining some momentum and pace, you have these kinds of attacks in the country," Habib Wardak, a national security analyst based in Kabul, told Al Jazeera.

"The Islamic State group claimed responsibility for the attack that happened last week on a mosque in Kabul, so despite the fact that you have these news and press conference from the government that they have eliminated ISIL, how can they conduct such sophisticated operations?"

Friday's blast had parallels to one earlier this month, when an explosion tore apart a famous Kabul mosque and led to the death of renowned Afghan cleric Maulvi Ayaz Niazi.

"In this attack, the imam seems to be the target, not the rest of the crowd. These are the imams who have supported the peace process with the Taliban movement," Wardak said.

"The other political aspect for these kinds of attacks is that there are peace spoilers trying to convey a message that peace with the Taliban will not eradicate violence in the country because you have ISIL."

Violence has spiked in recent weeks in Afghanistan with most of the attacks claimed by the ISIL affiliate.

The United States blamed the armed group for a horrific attack last month on a maternity hospital in the capital that killed 24 people, including two infants and several new mothers.

The ISIL affiliate also took responsibility for an attack on a bus carrying journalists in Kabul on May 30, killing two.

It also claimed credit for an attack on the funeral of a strongman loyal to the government last month that killed 35 people.

Meanwhile, the US is attempting to broker peace talks between the Afghan government and the Taliban to end 18 years of war.

Washington's peace envoy Zalmay Khalilzad was in the region earlier this week trying to resuscitate a US peace deal with the Taliban.

The peace deal signed in February calls for the withdrawal of the US and NATO troops from Afghanistan in return for a commitment by the Taliban to not launch attacks on the US or its allies.

London, Apr 7: British Prime Minister Boris Johnson was moved to the intensive care unit of a London hospital after his coronavirus symptoms worsened Monday, just a day after he was admitted for what were said to be routine tests.

Johnson was admitted to St. Thomas’ Hospital late Sunday, 10 days after he was diagnosed with COVID-19, the first major world leader to be confirmed to have the virus.

Downing Street said Johnson was conscious and did not require ventilation, but he was moved into intensive care in case he needs it later, his office said in a statement.

Britain has no official post of deputy prime minister, but Foreign Secretary Dominic Raab has been designated to take over should Johnson become incapacitated.

Hours earlier, Johnson tweeted that he was in good spirits and thanked the National Health Service for taking care of him and others with the disease.

“On the advice of my doctor, I went into hospital for some routine tests as I’m still experiencing coronavirus symptoms,″ Johnson said in the tweet. “I’m in good spirits and keeping in touch with my team, as we work together to fight this virus and keep everyone safe.″

The prime minister's spokesman said earlier Monday that Johnson had spent a comfortable night and remained in charge of government after being admitted to the hospital because his cough and fever persisted.

Johnson's spokesman, James Slack, refused to say what kind of tests Johnson was undergoing. He insisted that "the PM remains in charge of the government."

“He is receiving updates in hospital and is continuing to receive a (ministerial red) box" of files and briefing papers, Slack said.

Prime Minister Narendra Modi on Monday hoped that his British counterpart Boris Johnson, admitted to a hospital for treatment of coronavirus, finds himself in perfect health soon.

"Hang in there, Prime Minister @BorisJohnson! Hope to see you out of hospital and in perfect health very soon," the prime minister wrote on Twitter.

The 55-year-old leader had been quarantined in his Downing Street residence since being diagnosed with COVID-19 on March 26. He continued to preside at daily meetings on the outbreak until Sunday. He released several video messages during his 10 days in isolation urging Britons to stay home and observe social distancing measures to help slow the spread of the virus.

Speaking earlier at the government's daily coronavirus press briefing, Raab said Johnson was being “regularly updated," but said he had not spoken to him since Saturday.

“He's in charge, but he’ll continue to take doctors’ advice on what to do next," Raab said.

Politicians from all parties wished Johnson a quick recovery. Opposition Labour Party leader Keir Starmer tweeted: “Terribly sad news. All the country’s thoughts are with the Prime Minister and his family during this incredibly difficult time."

Johnson's fiancee, Carrie Symonds, who is pregnant, is herself recovering from coronavirus symptoms.

Johnson was admitted to the hospital as a message to the nation from Queen Elizabeth II was being broadcast Sunday evening. The 93-year-old monarch urged the public to show resolve and follow advice to stay inside.

Concerns had been growing about Johnson’s welfare ever since he posted a message Friday saying that he was feeling better, though was still feverish.

The virus causes mild to moderate symptoms in most people, but for some, especially older adults and the infirm, it can cause pneumonia and lead to death.

The government said Monday that 51,608 people had been confirmed to have the coronavirus in Britain, 5,373 of whom have died.

Derek Hill, a professor of medical imaging science at University College London, said that since COVID-19 causes difficulty breathing, one test performed on people with the disease is lung imaging with ultrasound or CT scans to see how badly they might be affected.

Hill said there are various types of breathing help, depending on the person and the difficulties.

“The reasons some people get seriously ill with COVID-19 while others have minor symptoms is not yet fully understood,″ Hill said. “But doctors managing these patients report that more men than women have serious problems, and patients who are overweight or have previous health problems are at higher risk."
