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.

Hello, 
I am writing from Space Exploration Architecture '?we are the team who designed Mars Ice House, the winner of NASA's Centennial Challenge for a 3D-Printed Habitat on Mars.

I noticed you posted a great article earlier this month about our project, Mars Ice Home. Could you please credit our project in your article by including a reference back to our website?

London, Mar 4: The UK government has reiterated its concern over the potential impact of the Citizenship Amendment Act (CAA) and said it is continuing to follow the events in India closely.

In response to an urgent question on “Recent Violence in India” tabled by Pakistani-origin Opposition Labour Party MP Khalid Mahmood in the House of Commons on Tuesday, UK’s Minister of State in the Foreign and Commonwealth Office (FCO) Nigel Adams said the UK engages with India at all levels, including on human rights, and also referred to the country's "proud history" of inclusive government and religious tolerance.

"The UK government also have concerns about the potential impact of the legislation (CAA),” said Adams, the Minister for Asia who was standing in for UK Foreign Secretary Dominic Raab, who is on a visit to Turkey.

"It is because of our close relationship with the government of India that we are able to discuss difficult issues with them and make clear our concerns where we have them, including on the rights of minorities. We will continue to follow events closely and to raise our concerns when we have with them,” said the minister.

While Mahmood, who had tabled the urgent question for an FCO statement, described the government response as “facile”, another Pakistani-origin MP Nusrat Ghani called on the government to relay the UK Parliament's concerns to the Indian authorities.

British Sikh Labour MP Tanmanjeet Singh Dhesi said the violence had brought back “painful personal memories” from the 1984 Sikh riots while he was studying in India and fellow Sikh MP Preet Kaur Gill also referenced 1984 in her intervention.

Other MPs sought to highlight the steps taken by the Indian authorities to restore “peace and tranquillity” in Delhi.

“He will be aware that it is not just Muslims who have been killed; Hindus have also been killed as part of the riots,” said Conservative Party MP Bob Blackman.

Scottish National Party (SNP) MP Alyn Smith sought the UK government’s intervention to share best practice around countering the online disinformation campaign being used in India to “inflame tensions”.

“We are in constant contact on these issues, and we know how important this is to Members of Parliament and their constituents, who may have family in the area,” said Adams, in his response.

May 22: A Pakistan International Airlines (PIA) flight on its way from Lahore to Karachi, crashed in the area near Jinnah International Airport on Friday, according to Civil Aviation Authority officials.

Geo News reported that the plane crashed at the Jinnah Ground area near the airport as it was approaching for landing. There were more than 90 passengers on board the Airbus aircraft. Black smoke could be seen from afar at the crash site, say eye witnesses.

There were no immediate reports on the number of casualties. The aircraft arriving from the eastern city of Lahore was carrying 99 passengers and 8 crew members, news agency AP said, quoting Abdul Sattar Kokhar, spokesman for the country’s civil aviation authority.

Witnesses said the Airbus A320 appeared to attempt to land two or three times before crashing in a residential area near Jinnah International Airport.

Flight PK-303 from Lahore was about to land in Karachi when it crashed at the Jinnah Garden area near Model Colony in Malir, just a minute before its landing, Geo News reported.

Local television reports showed smoke coming from the direction of the airport. Ambulances were on their way to the airport.

News agency said Sindh’s Ministry of Health and Population Welfare has declared emergency in all major hospitals of Karachi due to the plane crash.

It’s the second plane crash for Pakistani carrier in less than four years. The airline’s chairman resigned in late 2016, less than a week after the crash of an ATR-42 aircraft killed 47 people. The incident comes as Pakistan was slowly resuming domestic flights in the wake of the coronavirus pandemic, Bloomberg reported.

Jan 7: Body of the senior Iranian military commander, Qasem Soleimani killed in a U.S. drone strike in Iraq last week, has arrived in his home town of Kerman in southeast Iran for burial, the official IRNA news agency said on Tuesday.

State TV broadcast live images of thousands of people in the streets of the town, many of them dressed in black, to mourn Soleimani's death.

Soleimani was widely seen as Iran’s second most powerful figure behind Supreme Leader Ayatollah Ali Khamenei, 80, who wept in grief along with hundreds of thousands of mourners who thronged the streets of Tehran for Soleimani’s funeral on Monday.

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

He was killed while leaving Baghdad airport last Friday. Mourners packed the streets, 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 gathered in 1989 for the funeral of the Islamic Republic’s founder, Ayatollah Ruhollah Khomeini.

The killing of Soleimani has prompted fears around the world of a broader regional conflict, as well as calls in the U.S. Congress for legislation to keep President Donald Trump from going to war against Iran.
