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.

Hello, 
I am writing from Space Exploration Architecture '?we are the team who designed Mars Ice House, the winner of NASA's Centennial Challenge for a 3D-Printed Habitat on Mars.

I noticed you posted a great article earlier this month about our project, Mars Ice Home. Could you please credit our project in your article by including a reference back to our website?

Washington, Jul 14: Florida on Sunday reported a record 15,300 new coronavirus cases, the most by any state in a single day even as the coronavirus cases in the country have surged to 3,363,056.

The Washington Post reported that the huge number was result of both increased testing and widespread community transmission. The numbers shattered previous highs of 11,694 reported by California last week and 11,571 reported by New York on April 15.

Natalie E. Dean, an assistant professor of biostatistics at the University of Florida wrote that with Florida largely open for business, he doesn't expect this surge to slow.

Nationally, the conversation over reopening has become increasingly fraught amid the newly soaring case numbers, with much of the debate centering on whether schools should open their doors in the fall, reported the Post.

The Health workers in California and Texas too are facing an influx of COVID-19 patients where officials reported seven day averages for new cases - 8,664 and 9060 respectively.

According to the report, Florida has reported nearly 70,000 cases in last week alone, the most of any state.

Even though the COVID-19 cases are surging, Florida Gov. Ron DeSantis has stuck to an aggressive reopening plan with state officials recently ordering schools to reopen five days a week in the new academic year.

The state is also set to hold the Republican National Convention next month in Jacksonville's VyStar Veterans Memorial Arena, an indoor facility that seats about 15,000, reported Washington Post.

Seven-day averages for new cases -- considered a more reliable indicator of the virus's impact than single-day totals -- hit new highs in Alabama, Florida, Mississippi, Montana, North Carolina, Oklahoma and Puerto Rico.

Washington, Apr 2: The total US death toll from the coronavirus pandemic topped 4,000 early Wednesday, more than double the number from three days earlier, according to a tally by Johns Hopkins University.

The number of deaths was 4,076 -- more than twice the 2,010 recorded late Saturday.

More than 40 percent of recorded deaths nationally were in New York state, the Johns Hopkins data showed.

On Tuesday the United States exceeded the number of deaths in China, where the pandemic emerged in December before spreading worldwide.

The number of confirmed US cases has reached 189,510, the most in the world, though Italy and Spain have recorded more fatalities.

After initially downplaying the threat from new coronavirus in the early stages of the US outbreak, President Donald Trump warned of "a very, very painful two weeks" to come for the country on Tuesday.

Washington, Jan 2: The number of people killed in large commercial airplane crashes fell by more than 50% in 2019 despite a high-profile Boeing 737 MAX crash in Ethiopia in March, a Dutch consulting firm said on Wednesday. Aviation consulting firm To70 said there were 86 accidents involving large commercial planes - including eight fatal incidents - resulting in 257 fatalities last year. In 2018, there were 160 accidents, including 13 fatal ones, resulting in 534 deaths, the firm said.

To70 said the fatal accident rate for large airplanes in commercial passenger air transport was just 0.18 fatal accident per million flights in 2019, or an average one fatal accident every 5.58 million flights, a significant improvement over 2018. The fatality numbers include passengers, air crew such as flight attendants and any people on the ground killed in a plane accident

Large passenger airplanes in the study are aircraft used by nearly all travelers on airlines worldwide but excludes small commuter airplanes in service, including the Cessna Caravan and some smaller turboprop airplanes, according to To70.

On Dec. 23, Boeing's board said it had fired Chief Executive Dennis Muilenburg after a pair of fatal crashes involving the 737 MAX forced it to announce it was halting output of its best-selling jetliner. The 737 MAX has been grounded since March after an October 2018 crash in Indonesia and the crash of a MAX in Ethiopia in March killed a total of 346 people.

To70 said the aviation industry spent significant effort in 2019 "focusing on so-called 'future threats' such as drones." But the MAX crashes "are a reminder that we need to retain our focus on the basics that make civil aviation so safe: well-designed and well-built aircraft flown by fully informed and well-trained crews."

The Aviation Safety Network said on Wednesday that, despite the MAX crash, 2019 "was one of the safest years ever for commercial aviation." The 157 people killed in March on Ethiopian Airlines Flight 302 accounted for more than half of all deaths last year worldwide in passenger airline crashes.

Over the last two decades, aviation deaths around the world have been falling dramatically even as travel has increased. As recently as 2005, there were 1,015 deaths aboard commercial passenger flights worldwide, the Aviation Safety Network said.

Last week, 12 people were killed when a Fokker 100 operated by Kazakh carrier Bek Air crashed near Almaty after takeoff. In May, a Russian Sukhoi Superjet 100 aircraft caught fire as it made an emergency landing at Moscow’s Sheremetyevo airport, killing 41 people.

The figures do not include accidents involving military flights, training flights, private flights, cargo operations and helicopters.
