Nov 28, 2016: A journey to Mars presents many challenges, not the least of which will be how to feed the astronauts during what is expected to be a six-month journey to the Red Planet.
To that end, the U.S. space agency NASA is working to create lightweight food bars that provide calories without adding a lot of extra weight to the Orion spacecraft and the massive booster needed to get to Mars.
Unlike the International Space Station, where astronauts can choose from more than 200 food items, that’s simply not feasible on a mission to Mars, primarily because the amount of fuel needed to get to Mars means finding ways to save weight in other areas, like food. Also, the ISS is regularly resupplied with various consumables.

The food bars, for now at least, are being developed for breakfast, NASA said.
“When you have 700 to 900 calories of something, it’s going to have some mass regardless of what shape it’s in, so we’ve taken a look at how to get some mass savings by reducing how we’re packaging and stowing what the crew would eat for breakfast for early Orion flights with crew,” said Jessica Vos, deputy health and medical technical authority for Orion. “When you think about multi-week missions in Orion, having just one package for breakfast items for crew will help us limit the space we need to store them.”
While many Americans eat a protein bar in place of a meal from time to time, NASA said those are not good enough for the Mars mission.
“There’s no commercially-available bar right now that meets our needs, so we’ve had to go design something that will work for the crew, while trying to achieve a multi-year shelf-life,” said Takiyah Sirmons, a food scientist with the Advanced Food Technology team at NASA’s Johnson Space Center in Houston.
Some of the flavors being worked on include orange cranberry and barbecue nut.
NASA notes that for other meals, astronauts on their way to and from Mars will have food selection similar to the ISS.

One potential problem with food bars is that they may lower crew morale, as food choice, taste and quality are important on long missions.
So, NASA is also working on other ways to provide food to astronauts, including a vegetable production system like the one on the space station as well as other types of packaged foods.
The first manned launch of the Orion is expected as early as 2021, with manned missions to Mars coming sometime later. (VOA)
The Dragon is also doubling as an ice cream truck this time.
There was extra freezer space, so NASA packed little cups of vanilla, chocolate and birthday cake ice cream, as well as ice cream candy bars. Those treats should be especially welcomed by U.S. astronaut Peggy Whitson, in orbit since November. She’s due back at the beginning of September. Newly arrived U.S. spaceman Randolph Bresnik turns 50 next month.
The space station was zooming 250 miles above the Atlantic, just off Nova Scotia, when the Falcon took flight.
It was the 14th successful booster landing for SpaceX and the sixth on the giant X at the company’s touchdown spot at Cape Canaveral Air Force Station, just a few miles from its NASA-leased pad at Kennedy Space Center.
“It’s right on the bull’s-eye, and a very soft touchdown,” said SpaceX’s Hans Koenigsmann.
The mice on board are part of a study of visual problems suffered in space by some male astronauts. Scientists will study the pressure in the animals’ eyes, as well as the movement of fluid in their brains. Thirty days for mice in space is comparable to three years for humans, according to Florida State University’s Michael Delp, who’s in charge of the experiment. The study may help explain why female astronauts don’t have this vision problem, which can linger long after spaceflight, he added.
The Dragon also holds an instrument to measure cosmic rays from the space station. This type of device has previously flown on high-altitude balloons. The Army has an imaging micro-satellite on board for release this fall from the station. It’s a technology demo; the military wants to see how small satellites like this, with low-cost, off-the-shelf cameras and telescopes, might support critical ground operations. It’s about the size of a dormitory-room refrigerator.
Also going up on behalf of the Michael J. Fox Foundation: protein crystals that, in space, might shed light on Parkinson’s disease. The mission got a televised plug from Fox, an actor who has the disease.
Three Americans, one more than usual, and an Italian will tackle all this scientific work in orbit. The station also is home to two Russians; that number will go back up to three in a year or so.
This is the 13th delivery by the Hawthorne, California-based SpaceX, one of two private shippers hired by NASA. The other is Orbital ATK; its next supply run is in November from Wallops Island, Virginia.
The SpaceX Dragon is the only supply ship capable of returning items to Earth. It parachutes into the Pacific; the others burn up during re-entry.
This particular Dragon is brand new, as is the Falcon rocket. In June, SpaceX launched its first reused Dragon, and in March, its first reused Falcon. From now on, the company said it may only fly used Dragons.
SpaceX is also developing a crew Dragon for NASA astronauts, set to debut next year. Boeing is working on its own capsule to ferry space station astronauts.
In the meantime, SpaceX is aiming for a November debut of its Falcon Heavy rocket, which will feature three first-stage boosters and 27 engines, versus the single booster and nine engines on the Falcon 9. It will have two-thirds the thrust of NASA’s Saturn V rocket, which was used during the Apollo moon program. All three of the Falcon Heavy’s first-stage boosters are meant to fly back to a touchdown.

Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups
Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops
In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS
June 25, 2017: The Islamic State group is rapidly expanding in parts of Afghanistan, advancing militarily into areas where it once had a weak presence and strengthening its forces in core regions, according to Afghan and U.S. officials.
Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups.
Attacking IS has become such a priority in the country, that disparate forces sometimes join together in the ad-hoc fight, with Afghan and U.S. forces finding themselves inadvertently supporting the enemy Taliban in battling IS.
Confusion leads to mistakes
All too often, officials say, mistakes are made due to confusion on the ground.
Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops, provincial police chief, Rahmatullah Turkistani told VOA. The supplies were meant to help Afghan forces that are countering twin attacks by IS and Taliban militants but were used instead by IS.
“It’s not getting better in Afghanistan in terms of IS,” U.S. Chief Pentagon Spokeswoman Dana White told VOA this week. “We have a problem, and we have to defeat them and we have to be focused on that problem.”
Reinforcements for the IS cause reportedly are streaming into isolated areas of the country from far and wide. There are reports of fighters from varied nationalities joining the ranks, including militants from Pakistan, India, Iran, Iraq, Syria, Russia and Central Asian neighbors.
Still, the Islamic State-Khorasan (ISK) as IS is known in Afghanistan remains a fragmented group composed of differing regional forces with different agendas in different parts of the country.
“IS-K is still conducting low-level recruiting and distribution of propaganda in various provinces across Afghanistan, but it does not have the ability or authority to conduct multiple operations across the country,” a recent Pentagon report said. But where it operates, IS is inflicting chaos and casualties and causing confusing scenarios for disparate opponents.
In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS. IS regained ground after a few days, leading to U.S. military air attacks on IS positions in conjunction with Afghan intelligence instructions and army operations.
IS fighters reportedly have fled from mountain caves of Tora Bora, where al-Qaida’s leader Osama bin Laden hid from U.S. attack in 2001.
IS fighters were also reportedly advancing in neighboring Khogyani district, displacing hundreds of families, according to district officials. It is one of several areas in Nangarhar province, near the Pakistani border, where IS has been active for over two years.
Fierce clashes in the Chaparhar district of Nangarhar last month left 21 Taliban fighters and seven IS militants dead, according to a provincial spokesman. At least three civilians who were caught in the crossfire were killed and five others wounded.
“IS has overpowered Taliban in some parts of Nangarhar because the Taliban dispatched its elite commando force called Sara Qeta (Red Brigade) to other parts of the country, including some northern provinces to contain the growing influence of IS there,” Wahid Muzhda, a Taliban expert in Kabul, told VOA.
IS has also expanded in neighboring Kunar province, where, according to provincial police chief, it has a presence in at least eight districts and runs a training base, where foreign members of IS, train new recruits.
Hundreds of miles from Nangarhar, IS is attempting to establish a persistent presence in several northern provinces where it has found a fertile ground for attracting militants and recruiting unemployed youths, mostly between the age of 13 and 20.
IS has been able to draw its members from the Pakistani Taliban fighters, former Afghan Taliban, and other militants who “believe that associating with or pledging allegiance” to IS will further their interests, according to the Pentagon report.
Hundreds of militants have joined IS ranks in northern Jouzjan and Sar-e-Pul province where local militant commanders lead IS-affiliate groups in several districts.
Qari Hekmat, an ethnic Uzbek and former Taliban militant who joined IS a year ago, claims to have up to 500 members, including around 50 Uzbek nationals who are affiliated with the Islamic Movement of Uzbekistan (IMU) — previously associated with al-Qaida and Taliban in Afghanistan.
IS and Taliban are reportedly fighting over the control of Darzab district in Jouzjan which they stormed this week from two different directions and besieged scores of government forces. The Taliban has reportedly captured the center of the district while IS militants control the city outskirts.
Afghanistan faces a continuing threat from as many as 20 insurgent and terrorist networks present or operating in the Afghanistan-Pakistan region, including IS, the Pentagon said.
“In areas where the government has limited influence and control, IS attempts to emerge and expand there,” Ateequllah Amarkhail, an analysts and former Army general in Kabul told VOA.
IS has also claimed responsibility for several recent attacks in urban areas, however, with a hit-and-hide strategy that is proving effective. And it is engaging too in more skirmishes with U.S. forces that initially were sent to the country to help Afghan forces halt the spread of Taliban.
Three American service members based in eastern Afghanistan were killed in April during operations targeting IS militants, according to the Pentagon.
“ISIS-K remains a threat to Afghan and regional security, a threat to U.S. and coalition forces, and it retains the ability to conduct high-profile attacks in urban centers,” the Pentagon said. (VOA)

June 15, 2017: To a certain extent, a culture is defined by what is worn by its people. In a country as diverse as India, vast and varied spectrum of cultures and clothes is one of the specialties. Google’s latest virtual exhibition project now provides us the opportunity to explore and know more about it.
Google’s project ‘We Wear Culture’ is collaborating with 183 renowned cultural institutions from all around the world including India and its objective is to let people explore history of clothes dating as early as 3,000 years ago, from the ancient Silk Road to the unmatched elegance of the Indian Saree, from the courtly fashion of Versailles, to the Victorian ballgowns with intricate thread work.
According to Amit Sood, director of Google Arts and Culture,”We invite everyone to browse the exhibition on their phones or laptops and learn about the stories behind what you wear. You might be surprised to find out that your Saree, jeans or the black dress in your wardrobe have a centuries-old story. What you wear is true culture and more often than not a piece of art.”

The company also mentioned that noteworthy collections from Chhatrapati Shivaji Maharaj Vastu Sangrahalaya (CSMVS) and varied weaves from across India, from Gharchola to Patola to Temple to Ikat sarees will be included in the online project, as it intends to trace the story and importance of Indian textiles from ancient sculptures.
According to PTI reports, the world fashion exhibit also includes designs from north-eastern India including the weaves of tribes such as the Nagas, Meitis. it will showcase the traditional attire from Meghalaya called ‘Dhara’ or ‘Nara’ worn by the Khasi women as well.
As a part of the exhibit, Sewa Hansiba Museum has brought the unique colorful and rich embroidery arts, applique and mirror work from different communities such as the Ahir, Rabari, Chaudhury Patel and many others from the western part of India online.
The exhibition conducted by Salar Jung Museum brings to light the Sherwani and its journey of becoming the royal fashion statement of the Nizams from 19th century Hyderabad. Fashion and textiles enthusiasts can revisit Colonial Indian attires with Dr Bhau Daji Lad Mumbai City Museum. Over 400 online exhibitions and stories sharing a total of 50,000 photos, videos and other documents on world fashion are open to exploration as well.
The ‘We wear Culture’ initiative highlights significant events in the growth of the world fashion industry; the icons, the movements, the game changers and the trendsetters like Alexander McQueen, Christian Dior, Yves Saint Laurent, Gianni Versace, Audrey Hepburn and many more.
