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?

Munich, Feb 16: Iran's foreign minister said Saturday that US President Donald Trump is receiving bad advice if he believes an American "maximum pressure" campaign against his country will cause the government in Tehran to collapse.

Foreign Minister Mohammad Javad Zarif told a group of top defense officials and diplomats at the Munich Security Conference that the information provided to the president has dissuaded Trump from accepting offers from other leaders to mediate between Washington and Tehran.

"President Trump has been convinced that we are about to collapse so he doesn't want to talk to a collapsing regime," Zarif said.

To support his argument, the Iranian minister cited Trump's decision to pull out unilaterally in 2018 from Iran's nuclear deal with the US and other world powers. Trump said the landmark 2015 accord didn't address Iran's ballistic missile program or regional activities and needed to be renegotiated.

Since then, the Trump administration's re-imposition of US sanctions in a campaign of so-called "maximum pressure" have taken a severe toll on the Iranian economy and sent Iran's currency plunging.

"I believe President Trump, unfortunately, does not have good advisers," Zarif said. "He's been wanting for Iran to collapse since he withdrew from the nuclear deal." Zarif also said the killing of Iranian Gen. Qassem Soleimani in a US drone strike in Iraq on January 3 was a miscalculation by Washington that has galvanized support for Iran instead of increasing pressure on the regime.

The Iran nuclear deal, known as the Joint Comprehensive Plan of Action or JCPOA, promised Iran economic incentives in exchange for curbs on its nuclear program. It was intended to prevent Tehran from developing a nuclear bomb, which Iran insists it does not want to do.

Since the US withdrawal, the deal's other signatories - Germany, France, Britain, Russia and China - have unsuccessfully struggled to come up with ways to offset the effects of the new American sanctions.

Washington has pressured the other countries - so far without success - to abandon the deal entirely US Secretary of State Mike Pompeo said at the Munich Security Conference earlier Saturday that while there may be disagreements on what to do with the JCPOA, "when I talk to my counterparts here in Europe, everybody gets it."

"Everyone understands that these are folks who continue to build out their nuclear program," Pompeo said. "So there's a common understanding about the threat; we have tactical differences on how to proceed."

In recent months, Iran has steadily violated the limitations the deal placed on the amount of enriched uranium and heavy water it can stockpile, the number and type of centrifuges it can operate, and the purity of the uranium it enriches.

Iranian officials insist the moves are intended only to put pressure on the countries that remain part of the deal to provide economic help to Iran and that all the measures taken are fully reversible.

Zarif rejected Trump's suggestion of negotiating a new deal, saying the one negotiated during the Obama administration was the only vehicle for talks on Iran's nuclear program.

"There is no point in talking over something you already talked about. You don't buy a horse twice," he said.

"It's not about opening talks with the United States. It's about bringing the United States to the negotiating table that's already there," Zarif said.

Moscow, Aug 7: Russia will register its first vaccine against the coronavirus on August 12, Deputy Health Minister Oleg Gridnev said on Friday.

The vaccine has been developed jointly by the Gamaleya Research Institute and the Russian Defence Ministry.

"The vaccine developed by the Gamaleya centre will be registered on August 12. At the moment, the last, third, stage is underway. The trials are extremely important. We have to understand that the vaccine must be safe. Medical professionals and senior citizens will be the first to get vaccinated," Gridnev told reporters at the opening of a cancer centre building in the city of Ufa.

According to the minister, the effectiveness of the vaccine will be judged when the population immunity has formed.

Clinical trials of the vaccine began on June 18 and included 38 volunteers. All of the participants developed immunity. 

The first group was discharged on July 15 and the second group on July 20.

London, Mar 26: British Prime Minister Boris Johnson has said that the country's NHS risks becoming "overwhelmed" by the coronavirus outbreak and that the situation in Britain is just two or three weeks behind Italy.
"The numbers are very stark, and they are accelerating. We are only a matter of weeks -- two or three -- behind Italy," Johnson said, as reported by CNN.
"The Italians have a superb health care system. And yet their doctors and nurses have been completely overwhelmed by the demand. The Italian death toll is already in the thousands and climbing.
He added, "Unless we act together unless we make the heroic and collective national effort to slow the spread -- then it is all too likely that our own NHS will be similarly overwhelmed,"
"That is why this country has taken the steps that it has, in imposing restrictions never seen before either in peace or war." He said.
The problem reached a crunch point in the UK, which has dramatically increased its response to the virus outbreak this week.
Food banks that provide a lifeline for some of the estimated 14 million in poverty are running low on volunteers, many of whom have been forced to self-isolate, as well as the food itself, which is in short supply following panic-buying.
The UK has confirmed more 9,600 cases of the deadly virus with 460 deaths.
The global tally of cases has crossed 487,000 as on Thursday with 22,030 deaths globally as per the data presented by the Johns Hopkins University.
