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, Jan 9: The U.S. and Iran stepped back from the brink of possible war Wednesday as President Donald Trump signaled he would not retaliate militarily for Iran's missile strikes on Iraqi bases housing U.S. troops. No one was harmed in the strikes, but U.S. forces in the region remained on high alert.

Speaking from the White House, Trump seemed intent on deescalating the crisis, which spiralled after he authorized the assassination of Iran's top general, Qassem Soleimani. Iran responded overnight by firing more than a dozen missiles at two installations in Iraq, its most direct assault on America since the 1979 seizure of the U.S. Embassy in Tehran.

Trump's takeaway was that “Iran appears to be standing down, which is a good thing for all parties concerned and a very good thing for the world.”

The region remained on edge, however, and American troops including a quick-reaction force dispatched over the weekend were on high alert. Hours after Trump spoke, an ‘incoming’ siren went off in Baghdad's Green Zone after what seemed to be small rockets “impacted” the diplomatic area, a Western official said. There were no reports of casualties.

Iran's Supreme Leader Ayatollah Ali Khamenei said the overnight strike was not necessarily the totality of Iran's response. “Last night they received a slap,” Khamenei said. “These military actions are not sufficient (for revenge). What is important is that the corrupt presence of America in this region comes to an end.”

The strikes had pushed Tehran and Washington perilously close to all-out conflict and left the world waiting to see whether the American president would respond with more military force. Trump, in his nine-minute, televised address, spoke of a robust U.S. military with missiles that are “big, powerful, accurate, lethal and fast.'' But then he added: “We do not want to use it."

Iran for days had been promising to respond forcefully to Soleimani's killing, but its limited strike on two bases--one in the northern Iraqi city of Irbil and the other at Ain al-Asad in western Iraq--appeared to signal that it too was uninterested in a wider clash with the U.S. Foreign minister Mohammad Javad Zarif tweeted that the country had “concluded proportionate measures in self-defence.”

Trump said the U.S. was “ready to embrace peace with all who seek it.” That marked a sharp change in tone from his warning a day earlier that “if Iran does anything that they shouldn't be doing, they're going to be suffering the consequences, and very strongly.”

Trump opened his remarks at the White House by reiterating his promise that “Iran will never be allowed to have a nuclear weapon.” Iran had announced in the wake of Soleimani's killing that it would no longer comply with any of the limits on uranium enrichment in the 2015 nuclear deal crafted to keep it from building a nuclear device.

The president, who had earlier pulled the U.S. out of the deal, seized on the moment of calm to call for negotiations toward a new agreement that would do more to limit Iran's ballistic missile programmes and constrain regional proxy campaigns like those led by Soleimani.

Trump spoke of new sanctions on Iran, but it was not immediately clear what those would be.

Washington, Feb 19: Sri Srinivasan, a prominent Indian-American judge, has created history by becoming the first person of South Asian descent to lead a powerful federal circuit court considered next only to the US Supreme Court.

Srinivasan, 52, became the Chief Judge of the United States Court of Appeals for the DC Circuit.

An Obama appointee who has already been considered for a Supreme Court seat twice, donned the mantle of the chief judge of the DC federal court circuit on February 12.

Srinivasan succeeded Judge Merrick Garland, who has been a member of the DC Circuit since 1997 and Chief Judge since 2013. He will remain on the bench, a press release said.

Notably, Garland's nomination to the Supreme Court by the then president Barack Obama was blocked by Senate Republicans in 2016.

Srinivasan, was appointed to the US Court of Appeals for the District of Columbia Circuit in May 2013.

He was the first ever Indian-American to be appointed to the second most powerful court of the US.

Neomi Rao, nominated by President Donald Trump, is the second Indian American on this powerful judiciary bench.

History being made on the DC Court of Appeals. Congratulations, Judge Srinivasan! Senator Mark Warner said.

Congratulations to Judge Sri Srinivasan on becoming the Chief Judge of the U.S. Court of Appeals for the D.C. Circuit! A milestone for the Indian-American/Kansan community (and yet another piece of evidence my family can use that I'm underachieving), US Federal Communications Commission Chair Ajit Pai said.

According to The Washington Post, Srinivasan spoke recently about his path to the bench at an event celebrating women in the law, a field where men still dominate leadership positions.

"Everybody doubts their belonging and worthiness in some measure. I definitely did and still do. This is just going to be a part of the thing when you're looking out in the world in which everyone isn't like you. It's natural to doubt whether you belong and whether you're worthy, he said, "but you do belong and you are worthy.

Born in Chandigarh, and raised in Lawrence, Kansas, he received a B.A. from Stanford University, a J.D. from Stanford Law School, and an M.B.A. from the Stanford Graduate School of Business.

Following graduation, he served as a law clerk to Judge J. Harvie Wilkinson III of the US Court of Appeals for the Fourth Circuit, as a Bristow Fellow in the Office of the US Solicitor General, and as a law clerk to US Supreme Court Justice Sandra Day O'Connor.

From 2011 until his appointment to the US Court of Appeals, Judge Srinivasan served as the Principal Deputy Solicitor General of the United States.

He has argued 25 cases before the US Supreme Court. He has also taught appellate advocacy at Harvard Law School as well as a seminar on civil rights statutes and the Supreme Court at Georgetown University Law Center.
