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, Feb 14: Five years ago Britain’s new finance minister Rishi Sunak wasn’t even a member of parliament and now he is running the world's fifth largest economy.

The 39-year-old former Goldman Sachs banker was appointed in dramatic fashion on Thursday when incumbent Sajid Javid unexpectedly quit — in a row over advisers — during what Downing Street had cast as a routine ministerial reshuffle.

Sunak is married to the daughter of Infosys co-founder NR Narayana Murthy, and was hand-picked to take over an ultra-safe seat in northern England, previously represented by former Conservative Party leader William Hague. The Murthy family was not reachable for comment.

In July, when he was promoted chief secretary to the Treasury, Murthy had said: “Our advice to our children, including Rishi, has been to work hard, be honest, and do good for society…We wish him well.”

After Thursday’s announcement, Sunak said: “Delighted to be appointed... Lots to get on with.”

Tipped for Promotion

As Boris Johnson moves to increase control of the finance ministry, one of the youngest chancellors in history will face a prime minister who wants to increase government spending on everything from infrastructure and police to health and education.

Sunak, seen as a rising star in the ruling Conservative Party since he entered Parliament in 2015, had been tipped for promotion to a senior post in the ministerial rejig as Johnson put together his post-Brexit cabinet.

But, despite an already rapid ascent through the ranks of government, few expected the Oxford University Politics, Philosophy and Economics graduate to ascend to one of the highest offices in the land.

Sunak had been serving as Javid’s deputy in the finance ministry since Johnson promoted him upon taking office in July 2019. Prior to that he had served as a junior housing minister.

“From working in my mum’s tiny chemist shop to my experience building large businesses, I have seen first-hand how politicians should support free enterprise and innovation to ensure our future prosperity,” Sunak says on his website.

Smooth and loyal

Seen as a smooth media performer and ultra-loyal member of the Conservative Party, Sunak has been used by the government to present and defend their policies in television interviews — a sign of trust from Johnson, who has a fraught relationship with Britain’s media.

Sunak takes control at a critical juncture for Britain’s $2.7 trillion economy. He will have to steer the economy through the turbulence of leaving the European Union and the forging of new trade links that will define Britain’s new relationship with the world.

However, the power struggle that forced his predecessor Javid to quit hints at a more diminished role for what is the second most powerful position in the government — with Johnson’s office wanting to centralise control and minimise dissent.

Sunak is one of the three ministers of Indian origin in Johnson’s cabinet, the other two being Priti Patel and Alok Sharma. Patel remains the interior minister after the cabinet reshuffle while Sharma, a former minister for international development, was appointed the new minister for business. Sunak’s father was a doctor and his mother ran a chemist shop. Before entering politics he worked for Goldman Sachs and a hedge fund, then co-founded an investment firm. He also has an MBA from Stanford University.

Islamabad, Jan 3: The United Arab Emirates has extended USD 200 million aid to Pakistan for the development of the small and medium-sized enterprises in the country, Finance Adviser to Prime Minister Imran Khan said.

The announcement came after Abu Dhabi Crown Prince Sheikh Mohamed Bin Zayed Al Nahyan concluded his one-day visit to the country on Thursday.

"The money will be spent on small business promotion and jobs. This support is testimony to the expanding economic relations and friendship between our countries," the adviser, Abdul Hafeez Shaikh, on Thursday said.

The Crown Prince directed the Khalifa Fund for Enterprise Development to allocate USD 200 million in order to assist the Pakistani government's efforts to create a stable and balanced national economy that will help achieve the country's sustainable development, Dawn News reported on Friday.

During the visit, the prince met Prime Minister Khan and held talks on bilateral, regional and international issues.

The UAE is Pakistan's largest trading partner in the Middle East and a major source of investments. The UAE is also among Pakistan's prime development partners in education, health and energy sectors.

It hosts more than 1.6 million expatriate Pakistani community, which contributes remittances of around USD 4.5 billion annually to the GDP.

This is the Crown Prince's second visit to Pakistan since Khan took office in August 2018. He had last visited Pakistan on January 6 last year, just weeks after his country offered USD 3 billion financial assistance to Pakistan to deal with its balance of payment crisis.

The Crown Prince's visit was considered by experts as an attempt to woo Pakistan against the backdrop of recent developments when Saudi Arabia and UAE apparently used pressure to stop Pakistan from attending the Kuala Lumpur summit held last month.

The summit from December 19-21 was seen by Saudis as an attempt to create a new bloc in the Muslim world that could become an alternative to the dysfunctional Organisation of Islamic Cooperation led by the Gulf Kingdom.

President Donald Trump gave a new justification for killing Qassim Suleimani, telling a gathering of Republican donors that the top Iranian general was "saying bad things about our country" before the strike, which led to his decision to authorise his killing. "How much are we going to listen to?" Trump said on Friday, according to remarks from a fundraiser obtained by CNN.

With his typical dramatic flourish, Trump recounted the scene as he monitored the strikes from the White House Situation Room when Suleimani was killed. The president spoke in a ballroom at his Mar-a-Lago club in Palm Beach, Florida, at a Republican event that raised $10 million for Trump's 2020 campaign.

The January 3 killing of Suleimani prompted Iran to retaliate with missile strikes against US forces in Iraq days later and almost triggered a broad war between the two countries. "They're together sir," Trump said military officials told him. "Sir, they have two minutes and 11 seconds. No emotion. Two minutes and 11 seconds to live, sir. They're in the car, they're in an armoured vehicle. Sir, they have approximately one minute to live, sir. Thirty seconds. Ten, 9, 8 ...'"

"Then all of a sudden, boom," he said. "They're gone, sir. Cutting off, I said, where is this guy?" Trump continued. "That was the last I heard from him". It was the most detailed account that Trump has given of the drone strike, which has drawn criticism from some US lawmakers because neither the president nor his advisers have provided public information to back up their statements that Suleimani presented an "imminent" threat to US.

Trump's comments came a day after he warned Iran's supreme leader Ayatollah Ali Khamenei to be "very careful with his words". According to Trump, Khamenei's speech on Friday, in which he attacked the "vicious" US and described UK, France and Germany as "America's lackeys", was a mistake.
