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.

When 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: The race between Democratic leader Kamala Harris and her Republican rival Donald Trump for the White House has been truly unprecedented as it saw drama, tragedy, political comebacks, fierce rhetoric and a historically razor-tight contest.

As the fight reaches its crescendo with the big election day just a few hours away, many political observers billed the unpredictable race for the 47th President of the US as the most consequential one in decades while appearing to project a grim picture for the country’s future under a Trump presidency.

In her final days of campaign, Vice President Harris focused on a message of hope, unity, optimism and women rights whereas Trump remained fiercely combative in targeting his Democratic rival and even suggested that he may not accept the election outcome in case of a defeat.

Overall, it has been a roller-coaster ride for both 60-year-old Harris and 78-year-old Trump.

Trump received his party’s nomination in March and formally at the Republican National Convention (RNC) in July — in a historic comeback after remaining in political wilderness for months following several court cases.

In effect, he became the first former president to get the nomination for the top office on the planet after being convicted of a felony.

“Trump has made one of the biggest political comebacks since Richard Nixon’s in terms of the political struggles that he has had in the last four years,” Communication Strategist Anang Mittal said.

Just days ahead of the RNC, Trump was shot at during a rally in Pennsylvania. He suffered an upper ear injury. Minutes later, a bleeding Trump raised his fist in defiance, images that drew a lot of emotional support from his die-hard supporters.

For Harris too, it has been a dramatic ride after Biden ended his re-election campaign in July, nearly weeks after he came under severe scrutiny following his incoherent performance at a televised debate with Trump.

While dropping out from the race, Biden, 81, endorsed Harris to succeed him as the Democratic candidate.

Finally in August, the Democratic National Convention formally nominated Harris as the party’s candidate for the presidential election.

The presidential election will be a chance to “move past the bitterness, cynicism and divisive battles of the past”, she said in a powerful speech at the Convention.

If Harris wins, she will become the first woman, first Black woman and first person of South Asian descent to become the US President.

In the overall campaign, Harris has been projecting the election as the one to protect the country’s fundamental freedoms, safeguard constitutional values and ensure women’s rights.

On his part, Trump has maintained his signature aggressive rhetoric and promising to rebuild the economy and rid the US from illegal immigrants.

However, there has been strong criticism of the Republican leader’s roadmap to repair the economy.

"Donald Trump is offering a vision of crony rentier capitalism that has enticed many captains of industry and finance,” said Joseph E Stiglitz, a Nobel laureate economist, in a column in Project Syndicate.

"In catering to their wishes for more tax cuts and less regulation, he would make most Americans’ lives poorer, harder, and shorter,” he said.

With election day just a few hours away, there is no clarity on who has a better chance of winning the race.

"The elections are very close. They (the outcome) may change on the basis of a few thousands votes here or there. I think the big issue will be voter turnout tomorrow. That will determine the outcome in certain swing states,” said Executive Director of the US chapter of Observer Research Foundation Dhruva Jaishankar.

Kapil Sharma, a non-resident senior fellow at Atlantic Council’s Middle East Programmes, also echoed similar views.

“This election is probably one of the closest elections that I can remember. I have been working in Washington for over 30 years and I don’t recall an election being this tight,” he said.

More than 78 million Americans have already cast their votes as of Sunday, according to the University of Florida’s Election Lab that tracks early and mail-in voting across the US.

In a significant gesture towards a smooth transition, President Joe Biden invited President-elect Donald Trump to the White House to discuss the transfer of power, following a pledge from Vice President Kamala Harris to uphold a peaceful handover.

Vice President Harris, in a heartfelt address last night, publicly acknowledged Trump’s victory and assured her full commitment to a respectful and orderly shift in governance. "Our allegiance is not to any individual but to the Constitution itself," Harris emphasized, highlighting the need for national unity and respect for democratic processes.

Reports from The Washington Post reveal that Trump’s team is already hard at work on transition plans, actively considering candidates for key Cabinet positions. For Treasury Secretary, billionaire investor John Paulson and economic strategist Scott Bessent are in the running, while Senator Marco Rubio and former acting Director of National Intelligence Richard Grenell are top contenders for Secretary of State.

Additionally, the Trump camp is eyeing influential figures for strategic roles. North Dakota Governor Doug Burgum and former primary rival Vivek Ramaswamy are rumored to be cabinet-bound, with Senator Tom Cotton potentially taking on the role of Defense Secretary. The highest priority, however, is securing a Chief of Staff, with Trump advisor Susie Wiles and Brooke Rollins among the frontrunners for this critical post.

Trump's campaign has reportedly conducted a rigorous vetting process, aimed at bringing loyalists into his administration to ensure alignment with his goals. Campaign spokesperson Karoline Leavitt confirmed that personnel selections would be announced soon, while Trump spokesperson Steven Cheung confirmed that White House transition talks are imminent.

Adding to the intrigue, there are whispers that Robert F. Kennedy Jr. might take on a prominent role in restructuring health and food safety agencies. Known for his controversial views on vaccines, Kennedy’s potential appointment is already sparking debates across the political spectrum.

In his victory speech, President-elect Donald Trump showered praise on Elon Musk, calling him an "amazing guy" and "super genius." The SpaceX CEO’s satellite internet project, Starlink, received special attention for its role in providing critical connectivity after Hurricane Helene. With Starlink’s success making waves, speculation grows: will Musk bring his revolutionary tech to India’s vast, underserved areas?

In India, Musk’s increasing proximity to Trump and the President-elect’s endorsement has sparked curiosity and anticipation. Although regulatory barriers have delayed Starlink’s entry since 2021, recent policy shifts by India’s Communications Ministry could turn the tide. Minister Jyotiraditya Scindia recently announced plans to allocate satellite spectrum administratively, a move welcomed by Musk, who pledged to "serve the people of India" through Starlink.

What Makes Starlink Unique?
Unlike traditional broadband reliant on cables, Starlink uses thousands of low-earth orbit satellites to provide high-speed internet. This innovative approach bypasses the need for miles of overhead or underground wiring, making it ideal for remote and rural areas. Launched in 2019, Starlink now serves over 4 million users globally, and its entry into India could be transformative in bridging the digital divide.

Starlink’s India Journey So Far
Musk’s ambitions for India began in 2021 with pre-order invitations, but the government halted progress, citing licensing requirements. However, with Scindia’s recent announcement, Starlink may soon navigate the regulatory landscape, potentially setting the stage for a significant market entry.

Showdown with India’s Telecom Titans
If Starlink is allowed in, it could mean intense competition for Indian telecom leaders Mukesh Ambani’s Jio and Sunil Bharti Mittal’s Airtel. Both companies argue that satellite spectrum should be auctioned to maintain a level playing field, especially if Starlink expands to urban areas, challenging their established services.

While Starlink advocates for affordable, widespread access, Indian telecom giants claim global players often leverage rural connectivity narratives for favorable conditions, potentially overshadowing local providers in urban markets. As the government’s decisions unfold, a tech-driven tug-of-war could reshape India’s telecom landscape, with Musk’s Starlink poised as a powerful new player.
