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?

Washington, Feb 18: The upcoming visit of President Donald Trump to India later this month has the potential to usher in a new era of bilateral ties between the two countries, a top American business advocacy group has said.

President Trump will pay a state visit to India on February 24 and 25 at the invitation of Prime Minister Narendra Modi. He would be accompanied by First Lady Melania Trump.

This would be the president's first bilateral visit in the third decade of the 21st century and also the first after his acquittal by the Senate in the impeachment trial.

"I believe President Trump's upcoming visit to India has the potential to usher in a new era of our bilateral ties," Mukesh Aghi, President of the US India Strategic and Partnership Forum (USISPF) said in a statement on Monday.

On the sidelines of the visit, the USISPF, in collaboration with the Federation of Indian Chambers of Commerce and Industry (FICCI) and the ORF, has announced to organise a program entitled "US-India Forum: Partners for Growth".

The full-day discussion will focus on the key pillars defining India and the US' strategic, economic, and cultural partnership over the next decade.

"We have an opportunity before us to make real progress on multiple aspects of the relationship— whether it is upholding peace and security in the Indo-Pacific region; building upon an already strong energy partnership; developing co-production and co-development opportunities in the defense space; or strengthening bilateral trade," Aghi said.

"We look forward to an extremely successful visit and some concrete outcomes from the visit," he said.

The day-long programme on February 25 in New Delhi, will bring together over 500 senior business executives, members of the US-India think tank community and leading figures of the Indian diaspora to set the agenda for this strategic partnership.

Discussions during the day will touch upon areas, including the Indo-Pacific Strategy and Maritime Security; the US-India Defence Partnership, the US-India Energy Partnership, Elevating US-India Trade and Investment and Role of the Indian Diaspora in US-India Relations.

Seoul, Apr 26: A train presumed to belong to North Korean's Kim Jong-un has been spotted at a station in the state's eastern coastal town of Wonsan amid speculation about the leader's health, a US monitor said on Sunday, citing commercial satellite imagery on the region, Yonhap news agency reported.

According to 38 North-- a website devoted to analysis about North Korea, the imagery showed a train "probably belonging to Kim Jong Un parked at the Leadership Railway Station servicing his Wonsan compound since at least April 21."

"The approximately 250-metre long train, although partially covered by the station's roof, can be seen at a railway station reserved for use by the Kim family. It was not present on April 15 but was present on both April 21 and 23," it said.

"The train's presence does not prove the whereabouts of the North Korean leader or indicate anything about his health, but it does lend weight to reports that Kim is staying at an elite area on the country's eastern coast," it added.

The report came as rumours about his health have spread as Kim apparently skipped an important annual visit to the Kumsusan Palace of the Sun on the occasion of the April 15 birthday of late state founder and his grandfather, Kim Il-sung.

CNN intensified the speculation by reporting earlier last week that the United States is looking into intelligence that Kim is "in grave danger" after surgery.

Seoul officials have disputed recent media reports about Kim, saying there have been no unusual signs from the North. Some said that Kim is presumed to be staying in Wonsan for unspecified reasons.

Washington has also dismissed the reports, with US President Donald Trump calling such reports "incorrect" in a press briefing late last week.

On Saturday, other media reports stated that China has dispatched a team of medical doctors and officials to North Korea "to advise on" Kim, citing multiple unnamed people familiar with the situation.

North Korea's state media, however, has not made any mention of Kim's public activity for two weeks since he was last seen in April 11 presiding over a major party meeting, though it has reported on his handling of routine state affairs, such as sending diplomatic letters.
But not all speculation has proven to be false.

When he was absent from public for about a month in 2014, speculation arose about his health and a political crisis in the secretive state. He later reemerged with a cane and a limp reportedly after having a cyst removed from his ankle.

The 36-year-old leader is known to have various health problems apparently caused by obesity and heavy smoking. He took office as leader of the communist state after his father, Kim Jong-il, died of a heart attack in late 2011.

Hubei, Mar 25: As a bus departed from its terminus at Hankou Railway Station at 5:25 am Wednesday morning, Wuhan started to resume bus service after nine weeks of lockdown.

Apart from a driver, a safety supervisor was also on each bus, whose duty was to make sure all passengers are healthy.
"For those who do not use smartphones, they should bring with them a health certificate issued by the health authorities," said Zhou Jingjing, a safety supervisor aboard bus No. 511 departing from the Wuchang Railway Station complex.
The once hardest-hit city in central China's Hubei Province during the COVID-19 outbreak took unprecedented traffic restrictions on Jan 23. All of its public transport and all outbound flights and trains had been suspended in an attempt to contain the virus within the region.
