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.

US fast-food chain KFC has been forced to close over 100 restaurants in Malaysia over a pro-Palestine boycott of the company.

The Straits Times reported on Monday that the American restaurant chain specializing in fried chicken had to reduce its operations across Malaysia, mostly in north-eastern Kelantan state, following calls for a boycott of the company amid protests over the US government’s backing of the Israeli regime in its genocide of the Palestinians in the besieged Gaza Strip.

Nearly 80 percent, or 21 KFC outlets, in Kelantan state stopped their operations, followed by 15 outlets in Johor and 11 in Selangor, the most industrialized state in Malaysia.

Citing a local Chinese-language newspaper, the Straits Times added the local franchisor of the Louisville, Kentucky-headquartered company in the Muslim-majority Southeast Asian nation, QSR Brands Holdings Bhd, is temporarily suspending operations in more than 100 KFC outlets after about half a year of boycott movement. “QSR Brands, which owns and operates the KFC fast-food franchise in Malaysia, is suspending 108 outlets nationwide.”

In this regard, chairman of the pro-Palestinian group Boycott, Divestment, Sanctions (BDS) in Malaysia, Professor Mohd Nazari Ismail, told the Singapore-based newspaper that, “KFC is not on the BDS list of targeted companies. But many Malaysians see any American fast-food operator to be related to Israel, including KFC.” The BDS has been pushing for various forms of boycott movement against Israel until it meets its obligations under international law.

KFC was also forced to shut its first branch in Algeria earlier this month, just two days after its opening, following protests over US support to Israel.

The boycott action has severely affected worldwide operations of American fast-food giants McDonald’s, KFC, Starbucks, etc., with the pro-Palestine campaign having the potential to spread further across the globe.

Boycotted US companies are either perceived by pro-Palestinians to have taken pro-Israeli stances in the genocidal war on Gaza, or have financial ties to the Israel regime and/or have made illegal investments in the occupied Palestinian lands.

"I always wanted to be in a bar fight," said a US police official after pinning a Black man down on the ground and kneeling on his neck. The man later died at a hospital.

Ohio Police have come under intense scrutiny following the release of body camera footage showing officers pinning a Black man to the ground in a bar, reminiscent of the events that led to George Floyd's death in 2020.

The video, released by the Canton Police Department, captured the moments leading up to the death of Frank Tyson, a 53-year-old man suspected of leaving the scene of a single-car accident on April 18.

In the footage, officers are seen confronting Tyson inside a bar, where an altercation quickly ensues. Despite Tyson's pleas for help and his repeated cries of "I can't breathe," officers wrestle him to the ground and handcuff him, with one officer applying pressure to his back near his neck while saying, "You're fine." 

Tyson continues to plead for relief while lying on the floor. After several minutes, officers notice his lack of responsiveness and proceed to administer CPR. Paramedics arrive on the scene and transport Tyson to a local hospital, where he later dies.

In the body cam footage, one police officer can be heard bragging about how he always wanted to be in a "bar fight" with one of the patrons of the establishment. 

The circumstances surrounding Tyson's death draw chilling parallels to George Floyd's fatal encounter with Minneapolis Police in 2020 which sparked global outrage. 

The officers involved in Tyson's case, identified as Beau Schoenegge and Camden Burch, have been placed on administrative leave pending an investigation by the Ohio Bureau of Criminal Investigation.

An Indian-origin woman studying at the prestigious Princeton University in the US is among two students arrested over pro-Palestine protests on the campus, reports student and alumni newspapers.

Tamil Nadu-born Achinthya Sivalingan and Hassan Sayed were arrested after the protesters set up tents for an encampment in a university courtyard early Thursday morning, according to the Princeton Alumni Weekly (PAW).

The two graduate students were arrested on charge of trespassing and have been "immediately barred from the campus", said Jennifer Morrill, a university spokesperson, adding that setting up tents on the campus violated university policy.

However, they have not been evicted and will be allowed into their housing, another varsity spokesperson Michael Hotchkiss confirmed to the Daily Princetonian.

Ms Sivalingam is a student of Masters in Public Affairs in International Development at Princeton while Mr Sayed is a PhD candidate there.

In a statement, Morill said the students were given "repeated warnings from the Department of Public Safety to cease the activity and leave the area" and they now face disciplinary action. After their arrest, the other protesters "voluntarily" packed away their camping gear, she added.

Hotchkiss said the university did not evict anyone on Thursday and that the university allows students barred from campus to stay in their university-owned housing.

The undergraduate students were warned against occupation and encampment exercises in an email Wednesday, according to the Daily Princetonian.

Princeton students, faculty and community members, and even outsiders were part of the demonstration, the PAW cited organizers of the protest as saying. Large, white tents were set up nearby for upcoming reunions and other events.

A student who chose to be identified only as Urvi termed the arrests as "violent", which included the students being zip-tied around their wrists. The university, however, contested this and said the officers did not use any force and the arrests were made without any resistance.

Pro-Palestine protests have rocked the top US universities as thousands of students have hit their campuses to demonstrate against the Gaza deaths due to Israel’s inhuman military operation. 

The protests, which began at Columbia University in New York, have to colleges across the country and saw hundreds of students confronting cops and raising pro-Palestine slogans. The protesters have been calling on their universities to divest from companies that profit from the Gaza war and advocate an immediate ceasefire.

Who is Achinthya Sivalingan?

1. Achinthya Sivalingan was born in Coimbatore, Tamil Nadu and was raised in Columbus, Ohio.

2. She is pursuing a Master of Public Affairs (MPA) degree in International Development at Princeton University. Before that, Ms Sivalingan studied world politics and economics at Ohio State University and was also an Intern at Harvard Law School. 

3. Ms Sivalingan has significant experience in policy issues, having worked with civil society organisations, the legal system, politics, movement building, and private philanthropy. Her previous roles include supporting policy and advocacy work for climate adaptation, agricultural development, and nutrition portfolios at the Bill and Melinda Gates Foundation. 

4. Ms Sivalingan has worked on a congressional campaign in Ohio's third district and also contributed to land rights and policy initiatives in India at the Centre for Policy Research. 

5. She has been banned from Princeton over pro-Palestine protests and is now facing disciplinary action.
