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, Jul 21: Democrat Joe Biden urged Muslim Americans on Monday to join him in the fight to defeat President Donald Trump as he addressed an online summit hosted by the advocacy organisation Emgage Action to mobilise Muslim voters ahead of the presidential election.

I want to earn your vote not just because he's not worthy of being president, the presumptive presidential nominee told participants.

I want to work in partnership with you, make sure your voices are included in the decision-making process as we work to rebuild our nation.

Biden also reiterated a pledge to overturn a Trump administration ban on travelers from several predominantly Muslim countries, calling it vile.

Wa'el Alzayat, CEO of Emgage Action, said by email that the organisation was seeking to maximise Muslim American turnout in key battleground states.

In Michigan alone one of the states where the organisation has chapters and where Trump won in 2016 by fewer than 11,000 votes he said he believed there are more than 150,000 registered Muslim voters.

Several prominent Muslim American elected officials endorsed Biden for president in a letter organised by Emgage Action ahead of the summit.

Among those who signed the letter are Minnesota Rep. Ilhan Omar, Minnesota Attorney General Keith Ellison and Indiana Rep. Andre Carson, all Democrats.

Omar, one of the first Muslim women elected to Congress, served as a high-profile surrogate for Bernie Sanders before he exited the presidential race in April making her support for Biden potentially helpful as the former vice president seeks to mobilise Muslim voters this fall.

Muslim American voices matter to our communities, to our country, Biden said.

But we all know that your voice hasn't always gotten recognised or represented.

Emgage Action has titled the event Million Muslim Votes, underscoring its emphasis on boosting Muslim turnout in November.

Joe Biden's presence serves not only to galvanise Muslim Americans to cast their ballots, but to usher in an era of engaging with Muslim American communities under a Biden administration, Alzayat said by email before the summit.

The pro-Biden letter from Muslim American elected officials decried a number of Trump's domestic and international policies, including his administration's travel ban and his pullout from the Iran nuclear deal.

A Biden administration will move the nation forward on many of the issues we care about, the letter said, citing racial justice, affordable health care, climate change and immigration.

The Muslim American officials also praised Biden's agenda for their communities.

Among other goals, Biden has vowed to rescind the travel ban affecting Muslims on Day One if he's elected.

In his address, he pledged to include Muslim American voices in his administration, if elected, and to speak out against human rights abuses against Muslim minorities around the world.

I'll continue to champion the rights of Palestinians and Israelis to have a state of their own as I have for decades, each of them a state of their own, he said.

Other state- and local-level Muslim American officials signing onto the pro-Biden letter hail from several states, including Michigan.

Washington, Apr 17: The confirmed coronavirus death toll in the United States reached 32,917 on Thursday, according to a tally by Johns Hopkins University.

The toll as of 8:30 pm (0030 GMT Friday) marked an increase of 4,491 deaths in the past 24 hours, by far the highest daily toll in the pandemic so far.

But the figure likely includes "probable" deaths related to COVID-19, which were not previously included. This week, New York City announced it would add 3,778 "probable" coronavirus deaths to its toll.

As of Thursday night, the US Centers for Disease Control and Prevention had recorded 31,071 coronavirus deaths, including 4,141 "probable" virus deaths.

The US has the highest death toll in the world, followed by Italy with 22,170 dead although its population is just a fifth of that of the US.

Spain has recorded 19,130 deaths, followed by France with 17,920.

More than 667,800 coronavirus cases have been recorded in the United States, which has seen a record number of deaths over the past two days.

Meanwhile, President Donald Trump unveiled plans Thursday evening to reopen the US economy, allowing each state's governor "to take a phased deliberate approach to reopening their individual states".

Paris, Apr 10: French pharma major Sanofi said on Friday it has decided to donate 100 million doses of hydroxychloroquine, the anti-malaria drug which could be a potential weapon against novel coronavirus, across 50 countries.

The company has already doubled its incremental production capacity on top of the usual production for current indications across its eight hydroxychloroquine manufacturing sites worldwide and is on track to quadruple it by the summer.

"In this global health emergency, Sanofi stands ready to assist as many countries as possible, starting with countries where its medicine is registered for current approved indications as well as countries where there are no hydroxychloroquine suppliers or countries with underserved populations," it said in a statement.

Sanofi called for coordination among the entire hydroxychloroquine chain worldwide to ensure the continued supply of the medicine if proven to be a well-tolerated and effective treatment in COVID-19 patients.

"The COVID-19 pandemic is an unprecedented health and economic crisis which is shaking some of the very fundamentals of international solidarity and cooperation among countries," said Chief Executive Officer Paul Hudson. "This virus does not care about the concept of borders, so we should not either," he added.

"It is critical that international authorities, local governments, manufacturers and all other players involved in the hydroxychloroquine chain work together in a coordinated manner to ensure all patients who may benefit from this potential treatment can access it. If the trials prove positive, we hope our donation will play a critical role for patients," said Hudson.

While hydroxychloroquine is generating a lot of hope for patients around the world, said Sanofi, it should be remembered that there are no results from ongoing studies and the results may be positive or negative.

To date, there is insufficient clinical evidence to draw any conclusion over the safety and efficacy of hydroxychloroquine in the management of COVID-19 patients.

It is one of several medicines being investigated by the World Health Organisation (WHO) in its international clinical trial seeking a treatment solution for COVID-19. "Sanofi is supporting ongoing trials by providing the medicine to some participating investigator sites and other independent research centres," it said.
