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.

Washington, May 1:The novel coronavirus, that has killed over 230,000 people globally so far and has shattered economies, emerged from a virology lab in the Wuhan city of China, US President Donald Trump claimed Thursday with a high degree of confidence.

"Yes, I have. Yes, I have," Trump told reporters at the East Room of the White House when asked if he has seen anything at this point that gives him a high degree of confidence that the Wuhan Institute of Virology is where the virus originated.

The president, however, refuse to provide any details, except for saying that investigations are on and it would be out soon.

Asked what gave him a high degree of confidence that the virus originated from the Wuhan Institute of Virology, he said, "I can't tell you that. I'm not allowed to tell you that."

The president, however, did not hold his Chinese counterpart Xi Jinping responsible for this. "I don't want to say that, I don't want to say that, but certainly it could have been stopped. It came out of China and it could have been stopped and I wish they had stopped it and so does the whole world wish they had stopped it."

Reiterating that this is something that could have been contained at Wuhan ground zero, he said that China could have contained it. "They were either unable to, or they chose not to. And the world has suffered greatly."

One of two things happened, he reasoned. "They either didn't do it and you know they couldn't do it from a competent standpoint or they let it spread and I would say probably it got out of control."

"But there's another case that how come they stopped all of the planes and all of the traffic from going into China, but they didn't stop the planes and the traffic from coming into the United States and from coming into all over Europe," he said, citing the example of Italy, the hardest-hit European country.

"This country (the US) is very lucky and I'm very lucky that I put the ban on China, as you know, very early on. In January, we put the ban on China and that was a very early day. That wasn't a late day, that was an early day. Then, we later put the ban on in Europe," he said.

Before holding them accountable, Trump said he wants to find out what happened. "I think we'll be able to get a very good -- a very powerful definition of exactly what happened. We're working on it strongly now and I think it's going to be very powerful," he said.

"But they could have stopped it. They are a very brilliant nation, scientifically and otherwise. It got loose, let's say, and they could have capped it. They could have stopped it, but they didn't. And they stopped the planes from going to China, but they didn't stop them from going to the rest of the world. What was that all about?” he asked.

"We should have the answer to that in the not-too-distant future and that will determine a lot how I feel about China," Trump said.

When asked if President Xi misled him, Trump said, "Something happened. I don't say misleading or not. I'll let you know that. I mean, I'll be able to give you that answer at some point in the hopefully not-too-distant future."

The entire world has suffered as a result of this, he said.

"We have had tremendous death and tremendous sorrow, sadness, and nobody's ever seen anything like it. So, have most of the countries of the world. They've suffered tremendously. It's something that is going to have to be dealt with. We'll have to see," said the president.

London, Feb 19: UK Home Secretary Priti Patel today announced the launch of the Britain's new points-based visa system, aimed at attracting the "brightest and the best" from the world, including from India, and cutting down numbers of cheap, low-skilled workers coming to the country.

The new system will come into force from January 1, 2021 at the end of the transition period after the UK's exit from the European Union (EU) last month, which will formally end free movement of people within the economic bloc for the UK as a non-member.

The new post-Brexit system, which will apply equally to the EU and non-EU countries like India, is based on assigning points for specific skills, qualifications, salaries and professions, with visas only awarded to those who gain enough points.

"Today is a historic moment for the whole country. We're ending free movement, taking back control of our borders and delivering on the people's priorities by introducing a new UK points-based immigration system, which will bring overall migration numbers down," said Ms Patel, the senior-most Indian-origin Cabinet minister.

"We will attract the brightest and the best from around the globe, boosting the economy and our communities, and unleash this country's full potential," Ms Patel, in charge of the UK's visa and immigration system, said.

The UK Home Office said the new system is a direct response to the 2016 referendum in favour of Brexit, which was seen as a vote to end the country's reliance on cheap migrant labour and reduce overall levels of migration with tighter security.

"The new single global system will treat the EU and non-EU citizens equally. It will give top priority to those with the highest skills and the greatest talents, including scientists, engineers and academics," the Home Office said.

The Global Talent Scheme, a fast-track visa to be in operation from Friday, will also apply to the EU citizens from next year to allow highly-skilled scientists and researchers to come to the UK without a job offer.

Professor Alice Gast, President of Imperial College London, said: "British science is global. The new post-study work and Global Talent visas will help us to attract the world's brightest students and researchers, wherever they come from."

"From the race to develop a coronavirus vaccine to clean energy, British science's international collaborations drive innovation and excellence."

The government said the points threshold for the new system will be carefully set to attract the talent the UK needs. Skilled workers will need to meet a number of relevant criteria, including specific skills and the ability to speak English, to be able to work in the UK. All applicants will be required to have a job offer and, in line with the Migration Advisory Committee''s (MAC) recommendations, the minimum salary threshold will be set at 25,600 pounds - lower than the previous 30,000 pounds level for Tier 2 work visas.

The new points-based system will also expand the skills threshold for skilled workers.

Those looking to live and work in the UK will need to be qualified up to A-level or equivalent, rather than degree-level under the current system. This will provide greater flexibility and ensure UK business has access to a wide pool of skilled workers, the Home Office said.

In line with the British Prime Minister Boris Johnson's manifesto commitment in the December 2019 General Election, there will be no specific route for low-skilled workers.

"It is estimated 70 per cent of the existing EU workforce would not meet the requirements of the skilled worker route, which will help to bring overall numbers down in future," the Home Office said.

Student visa routes will also be points-based and be opened up to EU citizens from next year.

Those wishing to study in the UK will need to demonstrate that they have an offer from an approved educational institution, that they can support themselves financially and that they speak English.

To address the specific labour concerns of the agricultural sector reliant on seasonal workers from the EU, the Seasonal Workers Pilot will be expanded in time for the 2020 harvest from 2,500 to 10,000 places.

EU citizens and other non-visa nationals will not require a visa to enter the UK when visiting the UK for up to six months.

However, the use of national identity cards will be phased out for travel to the UK and the Home Office highlighted that as part of its post-Brexit offer, those EU citizens resident in the UK by December 31 2020 can still apply to settle in the UK through the EU Settlement Scheme until June 2021.

Tehran, Feb 28: The coronavirus epidemic in Iran has cost 26 lives, the health ministry announced Thursday, with a vice president becoming the latest top official to be infected as the spread appeared to accelerate.

Health ministry spokesman Kianoush Jahanpour told a news conference that the tally of infections had risen to 245 with 106 more cases confirmed -- the highest number for a single day since Iran announced its first infections on February 19.

The Islamic republic has the highest death toll from the virus outside China, where COVID-19 first emerged.

Among the latest coronavirus sufferers is one of Iran's seven vice presidents, Massoumeh Ebtekar, who oversees women's affairs.

Ebtekar, a former spokeswoman for students who took 52 Americans hostage at the US embassy in Tehran in 1979, is being treated at home and members of her team have been tested, state news agency IRNA reported.

Mojtaba Zolnour, head of parliament's national security and foreign affairs committee, also contracted the virus, appearing in a video posted by Fars news agency saying he was in self-quarantine.

The cleric is a deputy for the Shiite holy city of Qom in central Iran where the country's first cases were detected.

According to media reports, among the deceased in Qom on Thursday was theologian Hadi Khroroshahi, who in 1981 was named Iran's first ambassador to the Vatican.

The announcement by Zolnour comes two days after another top official, deputy health minister Iraj Harirchi, head of the government's coronavirus task force, said he too had contracted the virus.

On Wednesday, Iranian authorities announced domestic travel restrictions for people with confirmed or suspected infections.

They also placed curbs on access to major Shiite pilgrimage sites, including the Imam Reza shrine in second city Mashhad and the Fatima Masumeh shrine in Qom.

Visitors to the shrines will be allowed to visit on condition they are provided "with hand-washing liquids, proper (health) information, masks", Health Minister Saeed Namaki said.

They must "not gather together in groups but just pray and leave", he said.

In a rare move, authorities announced the cancellation of the main Friday weekly prayers in Tehran, Qom and Mashhad as well as in the capitals of 22 of Iran's 31 provinces and other infected areas.

"All of these decisions are temporary and if the situation changes, we might intensify or ease them," Namaki said.
