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.

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.

Washington, May 30: President Donald Trump said Friday he would strip several of Hong Kong's special privileges with the United States and bar some Chinese students from US universities in anger over Beijing's bid to exert control in the financial hub.

In a day of concerted action, the United States and Britain also raised alarm at the UN Security Council over a controversial new security law for Hong Kong, angering Beijing which said the issue had no place at the world body.

In a White House appearance that Trump had teased for a day, the US president attacked China over its treatment of the former British colony, saying it was "diminishing the city's longstanding and proud status."

"This is a tragedy for the people of Hong Kong, the people of China and indeed the people of the world," Trump said.

Trump also said he was terminating the US relationship with the World Health Organization, which he has accused of pro-China bias in its management of the coronavirus crisis.

But Trump was light on specifics and notably avoided personal criticism of President Xi Jinping, with whom he has boasted of having a friendship even as the two powers feud over a rising range of issues.

"I am directing my administration to begin the process of eliminating policy that gives Hong Kong different and special treatment," Trump said.

"This will affect the full range of agreements, from our extradition treaty to our export controls on dual-use technologies and more, with few exceptions," he said.

Secretary of State Mike Pompeo on Wednesday informed Congress that the Trump administration would no longer consider Hong Kong to be separate under US law, but it was up to Trump to spell out the consequences.

China this week pressed ahead on a law that would ban subversion and other perceived offenses against its rule in Hong Kong, which was rocked by months of massive pro-democracy protests last year.

US restricts students

In one move that could have long-reaching consequences, Trump issued an order to ban graduate students from US universities who are connected to China's military.

"For years, the government of China has conducted elicit espionage to steal our industrial secrets, of which there are many," Trump said.

Hawkish Republicans have been clamoring to kick out Chinese students enrolled in sensitive fields. The FBI in February said it was investigating 1,000 cases of Chinese economic espionage and technological theft.

But any move to deter students is unwelcome for US universities, which rely increasingly on tuition from foreigners and have already been hit hard by the COVID-19 shutdown.

China has been the top source of foreign students to the United States for the past decade with nearly 370,000 Chinese at US universities, although Trump's order will not directly affect undergraduates.

Critics say Trump has been eager to fan outrage about China to deflect attention from his own handling of the coronavirus pandemic that has killed more than 100,000 people in the United States, the highest number of deaths of any country.

Chuck Schumer, the top Democrat in the Senate, called Trump's announcement "just pathetic."

Eliot Engel, a Democrat who heads the House Foreign Affairs Committee, noted that Trump treaded lightly on Hong Kong during last year's protests as he sought a trade deal with Xi.

"Now, the president wants to shift the blame for his failures onto China, so he's doing the right thing for the wrong reason," Engel said.

Trump's order could also trigger retaliation. China in March expelled US journalists after the Trump administration tightened visa rules for staff at Chinese state media.

Clash at UN

The United States and Britain earlier in the day urged China to reconsider the Hong Kong law during talks at the UN Security Council, where China wields a veto -- making any formal session, let alone action against Beijing, impossible.

The Western allies raised Hong Kong in an informal, closed-door videoconference where China cannot block the agenda.

They said China was violating an international commitment as the 1984 handover agreement with Britain, in which Beijing promised to maintain the financial hub's separate system until at least 2047, was registered with the United Nations.

"The United States is resolute, and calls upon all UN members states to join us in demanding that the PRC immediately reverse course and honor its international legal commitments to this institution and to the Hong Kong people," said US Ambassador Kelly Craft, referring to the People's Republic of China.  

China demanded that the United States and Britain "immediately stop interfering in Hong Kong affairs," saying the law did not fall under the Security Council's mandate.

"Any attempt to use Hong Kong to interfere in China's internal matters is doomed to fail," warned a statement from China's UN mission.

"There was no consensus, no formal discussion in the Security Council, and the US and the UK's move came to nothing," it said.

Washington, Mar 1: The US Federal Communications Commission (FCC) has proposed a fine of over $200 million for all major US mobile carriers for selling the location data of customers to some agencies.

The Federal Communications Commission today proposed fines against the nation's four largest wireless carriers for apparently selling access to their customers' location information without taking reasonable measures to protect against unauthorised access to that information. As a result, T-Mobile faces a proposed fine of more than $91 million, AT&T faces a proposed fine of more than $57 million, Verizon faces a proposed fine of more than $48 million, and Sprint faces a proposed fine of more than $12 million, the FCC said in a statement on Friday.

The Enforcement Bureau of FCC opened this investigation after reports surfaced that a Missouri Sheriff, Cory Hutcheson, used a "location-finding service" operated by Securus, a provider of communications services to correctional facilities, to access the location information of the wireless carriers' customers without their consent between 2014 and 2017.

"American consumers take their wireless phones with them wherever they go. And information about a wireless customer's location is highly personal and sensitive. The FCC has long had clear rules on the books requiring all phone companies to protect their customers' personal information. And since 2007, these companies have been on notice that they must take reasonable precautions to safeguard this data and that the FCC will take strong enforcement action if they don't. Today, we do just that," said FCC Chairman Ajit Pai.

"This FCC will not tolerate phone companies putting Americans' privacy at risk."

The FCC also admonished these carriers for apparently disclosing their customers' location information, without their authorisation, to a third party

The four major US carriers mentioned sold access to their customers' location information to "aggregators," who then resold access to such information to third-party location-based service providers (like Securus).

Although their exact practices varied, each carrier relied heavily on contract-based assurances that the location-based services providers (acting on the carriers' behalf) would obtain consent from the wireless carrier's customer before accessing that customer's location information.
