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.

London, Mar 27:  British Prime Minister Boris Johnson said Friday he has tested positive for the new coronavirus, but remains in charge of the U.K.'s response to the outbreak.

Johnson's office said he was tested on the advice of the chief medical officer after showing mild symptoms.

It said Johnson is self-isolating at his 10 Downing St. residence and continuing to lead the country's response to COVID-19.

In a video message, Johnson said he had a temperature and a persistent cough.

Over the last 24 hours I have developed mild symptoms and tested positive for coronavirus.

I am now self-isolating, but I will continue to lead the government’s response via video-conference as we fight this virus.

Together we will beat this. #StayHomeSaveLives pic.twitter.com/9Te6aFP0Ri

"Be in no doubt that I can continue, thanks to the wizardry of modern technology, to communicate with all my top team, to lead the national fightback against coronavirus."

Earlier this week Britain’s Prince Charles announced that he had tested positive for the virus.

Pentagon, Jan 25: Thirty-four US troops had been diagnosed with concussions and traumatic brain injury (TBI) as a result of the January 8 Iranian missile attack on two military bases in Iraq housing American soldiers, the Pentagon said.

"Eight service members who were previously transported to Germany have been brought to the US, they would continue to receive treatment in the US either at Walter Reed or their home bases," Pentagon spokesman Jonathan Hoffman told the media on Friday.

Hoffman said that nine service members were still undergoing treatment in Germany, and the rest of the 17 injured troops have already returned to duty in Iraq, reports Xinhua news agency.

Lat week, the US military had said that 11 service members were treated for concussion symptoms due to the missile attacks.

Hoffman noted that the symptoms "are late developing and manifested over a period of time".

In retaliation for the killing of Iranian Major General Qasem Soleimani in an American drone attack on January 3 in Baghdad, Tehran launched over 13 ballistic missiles on the two military bases in Anbar and near the city of Erbil.

US military initially said that no casualty was reported from the Iranian attack. President Donald Trump then downplayed the seriousness of those injures.

"I heard that they had headaches and a couple of other things, but I would say and I can report that it's not very serious," Trump told reporters on Wednesday at a press conference in Davos, Switzerland.

More than 5,000 US troops are deployed in Iraq to support the country's forces in the battle against Islamic State militants.

United Nations, Jun 6: US President Donald Trump’s response to protests against the killing of African-American George Floyd has included language “directly associated with racial segregationists” from America's past, a group of UN human rights experts have said.

There have been widespread protests across the United States as Floyd, 46, was killed by a white police officer in Minneapolis. People from diverse backgrounds have called for justice and have voiced their support to the protests.

In the wake of protests over the killing of Floyd, Trump had tweeted that “when the looting starts, the shooting starts.”

“The response of the President of the United States to the protests at different junctures has included threatening more state violence using language directly associated with racial segregationists from the nation’s past, who worked hard to deny black people fundamental human rights," a statement issued on Friday by over 60 independent experts of the Special Procedures of the United Nations Human Rights Council said.

"We are deeply concerned that the nation is on the brink of a militarised response that reenacts the injustices that have driven people to the streets to protest,” it said.

A report in The New York Times had said that the phrase "When the looting starts, the shooting starts” was used by Miami’s former police chief Walter Headley in 1967. Headley had been “long accused of using racist tactics in his force’s patrols of black neighbourhoods,” the NYT had said.

They said the recent killing of Floyd has shocked many in the world, “but it is the lived reality of black people across the United States. The uprising nationally is a protest against systemic racism that produces state-sponsored racial violence, and licenses impunity for this violence.”

They noted that following the recent spate of killings of African-Americans, many in the United States and abroad are finally acknowledging that “the problem is not a few bad apples” but instead the problem is the very way that economic, political and social life are structured in a country that prides itself in liberal democracy, and with the largest economy in the world.

Separately, 28 UN experts called on the US Government to take decisive action to address systemic racism and racial bias in the country's criminal justice system by launching independent investigations and ensuring accountability in all cases of excessive use of force by police.

“Exactly 99 years after the massacre in Tulsa, involving the killing of people of African descent and the massive loss of life, destruction of property and loss of wealth on ‘Black Wall Street’, African Americans continue to experience racial terror in state-sponsored and privately organised violence,” the experts said.

Strongly condemning the killings of Ahmaud Arbery, Breonna Taylor and George Floyd, the experts called for systemic reform and justice. “Given the track record of impunity for racial violence of this nature in the United States, Black people have good reason to fear for their lives.”

Taylor, a 25-year-old emergency medical technician was shot in her bed when police raided the wrong house; Arbery, 25, was fatally shot while jogging near his home by three white men who chased and cornered him; and Floyd was accused of using counterfeit currency in a store and died in the street while a white officer knelt on his neck and three others participated and observed.

“The origin story of policing in the United States of America starts with slave patrols and social control, where human property of enslavers was ‘protected’ with violence and impunity against people of African descent. In the US, this legacy of racial terror remains evident in modern-day policing,” the experts said.

The experts also raised concern about the police response to demonstrations in several US cities, termed by some the ‘Fed Up-rising’, that have been marked by violence, arbitrary arrest, militarisation and the detention of thousands of protesters. Reporters of colour have been targeted and detained, and some journalists have faced violence and harassment.

“Statements from the US Government inciting and threatening violence against protesters stand in stark contrast to calls for leniency and understanding which the Government had issued in the wake of largely white protests against COVID-19 restrictions on services like barbershops, salons, and spas,” the experts said.
