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?

May 12: Gunmen stormed a hospital on Tuesday in an ongoing attack in the Afghan capital Kabul, as a suicide blast killed 15 people at a funeral in the country's restive east.

Special forces rescued 80 people including mothers and babies from the Kabul hospital after three gunmen launched a morning assault, killing at least four people, the interior ministry said in a statement.

Heavily armed forces were seen carrying babies wrapped in blankets away from the scene, as the clearance operation continued.

The facility, which has a large maternity ward, is located in the west of the city, home to the capital's minority Shiite Hazara community -- a frequent target of Sunni militants from the Islamic State group.

The flare-up in violence comes as Afghanistan grapples with myriad crises including a rise in militant operations across the country and a surge in coronavirus infections.

A paediatrician who fled the hospital told AFP he heard a loud explosion at the entrance of the building.

"The hospital was full of patients and doctors, there was total panic inside," he said, asking not to be named.

The maternity services at the hospital are supported by humanitarian organisation Doctors Without Borders (MSF).

"Hospitals and health workers must not be attacked. We call on all sides to stop attacking hospitals and health workers," said deputy health minister in the city, Waheed Majroh.

Around an hour later, a suicide bomber killed at least 15 people at the funeral of a local police commander in the country's eastern Nangarhar province, according to provincial spokesman Ataullah Khogyani.

The attacker detonated his explosives in the middle of the ceremony.

Zaher Adel, spokesman for the government hospital in Jalalabad, earlier said 12 bodies had arrived from the blast site and more than 50 people were being treated for injuries.

Amir Mohammad, who was wounded in the blast, said thousands of people had gathered for the funeral, an event which often draws huge crowds in Afghanistan.

The violence comes just a day after four roadside bombs exploded in a northern district of Kabul, wounding four civilians including a child.

The bombings were later claimed by the Islamic State group, according to the SITE intelligence group.

They were just the latest in a string of IS attacks on the capital.

In March, at least 25 people were killed by a gunman at a Sikh temple in Kabul, which was later claimed by the group.

IS is also responsible for an infamous attack in March 2017 on one of the country's largest hospitals, when gunmen disguised as doctors stormed the Kabul building and killed dozens.

In recent months, the jihadist group has suffered mounting setbacks after being hunted by US and Afghan forces as well as Taliban offensives targeting their fighters, but it still retains the ability to launch major assaults on urban centres.

The Taliban have largely refrained from launching large attacks on Afghan cities since February when they signed a landmark withdrawal deal with the US meant to pave the way for peace talks with the Kabul government.

Under the agreement, the Taliban promised not to target forces from the US-led coalition, but made no such pledge toward Afghan troops and have stepped up attacks in the provinces.

The Taliban have denied involvement in both of Tuesday's attacks.

New Delhi, Feb 21: Global terror financing watchdog FATF on Friday decided continuation of Pakistan in the "Grey List" and warned the country that stern action will be taken if it fails to check flow of money to terror groups like the LeT and the JeM, sources said.

The decision has been taken at the Financial Action Task Force's plenary in Paris.

The FATF decided to continue Pakistani in the "Grey List". The FATF also warned Pakistan that if it doesn't complete a full action plan by June, it could lead to consequences on its businesses, a source said.

Balochistan, May 1: Sajid Hussain, Editor-in-Chief of Balochistan Times, has been found dead in a Swedish town, the police have confirmed.

The Swedish police informed his family on Thursday night that they discovered his body from a river in Uppsala, The Times reported.
The Baloch journalist had been missing from the Swedish city since March 2 this year.

Sajid, 39, left Pakistan in 2012 and had been living as a refugee in Sweden since 2017. He wrote extensively on the suffering of the Balochis at the hands of the Pakistani military establishment.

His work often got him into trouble as the authorities did not like his reporting of Balochistan's forbidden stories, the reason he had to leave and live in exile.

The Baloch journalist was found dead two months after he went missing in Sweden.
Sajid left Pakistan because of security threats from Pakistan Army and its intelligence service ISI.

The spokesperson of the Baloch National Movement, Hammal Haider told news agency: "We are deeply saddened by the demise of prominent Baloch intellectual and writer Sajid Hussain."
"His death is indeed a loss of a great mind for the people of Balochistan. Due to his straightforwardness, he was loved among all journalistic, literary and political circles," added Haider.

"After this incident, we have serious concerns about our members and other Baloch refugees living in the West," he said.
