New Zoosh technology provides NFC capabilities without the chip Citation: Microsoft India team develop secure Peer-to-Peer acoustic NFC system (2013, August 16) retrieved 18 August 2019 from https://phys.org/news/2013-08-microsoft-india-team-peer-to-peer-acoustic.html Standard NFC communications, based on RFID, allow two devices to communicate with one another without having to access a network. Despite a lot of press coverage (and hardware to support it becoming standard in a lot of phones) NFC has failed to take off—for it to succeed other vendors, such as grocery stores, would need to add hardware to their existing equipment. To get around this problem, the engineers in India have done away with the need for additional hardware choosing instead to take advantage of the acoustic abilities inherent in virtually any smartphone (including the iPhone). It works on roughly the same principle as old-school modems, which means it uses beeps, squeaks, squawks and other noises to send and receive data.Dhwani is slow by any measure with a data rate of just 2.4 Kbps. For that reason, no one is going to be using it to send pictures or video, instead, it’s meant to send data such as that used for digital wallet transactions. The development team says it’s more secure than RFID based NFC communications as well because it’s based on a Jam-Secure technique—where it sends self-jamming noise along with self-cancelation to avoid eavesdropping—anyone else listening in would hear only chaotic noise.To use the new system, two phone users download the software, run it, then place their phones together where the speaker for one is next to the microphone of the other (its range is approximately 10 centimeters). The developers claim that ambient noise won’t pose a problem for the exchange, thus paving the way for its use in virtually any environment where people use their phones.Of course for the system to work, other vendors must write apps for it to allow the two phones, or phone and other equipment to carry out proprietary transactions. Whether that will happen or not, is still unclear, but if it does, the new software could be a game-changer. This document is subject to copyright.

Journal information: Journal of the Royal Society Interface Large moths need to hear better Bats, as most are aware, make their way through the air using echolocation—they emit sounds and listen as the sounds are bounced back to them after hitting something. This ability not only helps them avoid running into things in dark, but it’s the means by which they identify and catch prey. In this new effort, the researchers found that changes in air temperature of just a few degrees could have a profound impact on the echolocation abilities of bats around the world.Attenuation—the tendency of sound to lose volume and clarity as it moves through the air (or other materials) is impacted by a variety of factors, such as humidity, wind and of course heat—low frequency sounds are less impacted than are high frequency sounds. This means that bats that live in temperate climates such as North America or Europe (who use high frequency chirps) are likely to face more challenges than low frequency chirping bats living in the tropics, as global temperature rise.Of course nothing in nature is as simple as that, other factors have an impact on survival of species as well, and global warming is almost certain to cause environmental impacts that no one foresaw. But, what is clear from this new study is that some bats are likely to be winners, and some losers, because of where they live. Those that live in temperate climates but who use low frequencies, for example, might find the hunting getting easier. Others who are slow to adapt, on the other hand, may find the added stress of having to chirp louder, lower or more often, too much to bare leaving them with too little energy to mate.An associated finding with this study is that it highlights the fact that the more the impact of global warming is studied, the more we discover just how far and wide the impact will be felt, both on a global scale, and within simple communities, such as those occupied by bats. Citation: Study shows global warming likely to alter bat echolocation abilities (2013, December 11) retrieved 18 August 2019 from https://phys.org/news/2013-12-global-echolocation-abilities.html More information: Global warming alters sound transmission: differential impact on the prey detection ability of echolocating bats, Published 11 December 2013 DOI: 10.1098/rsif.2013.0961AbstractClimate change impacts the biogeography and phenology of plants and animals, yet the underlying mechanisms are little known. Here, we present a functional link between rising temperature and the prey detection ability of echolocating bats. The maximum distance for echo-based prey detection is physically determined by sound attenuation. Attenuation is more pronounced for high-frequency sound, such as echolocation, and is a nonlinear function of both call frequency and ambient temperature. Hence, the prey detection ability, and thus possibly the foraging efficiency, of echolocating bats and susceptible to rising temperatures through climate change. Using present-day climate data and projected temperature rises, we modelled this effect for the entire range of bat call frequencies and climate zones around the globe. We show that depending on call frequency, the prey detection volume of bats will either decrease or increase: species calling above a crossover frequency will lose and species emitting lower frequencies will gain prey detection volume, with crossover frequency and magnitude depending on the local climatic conditions. Within local species assemblages, this may cause a change in community composition. Global warming can thus directly affect the prey detection ability of individual bats and indirectly their interspecific interactions with competitors and prey. This document is subject to copyright.

Credit: Moussa, et al. ©2015 IOP Publishing By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge’s porous structure. The pores provide a large surface area for the electrode materials to attach to, leading to an increase in ion movement between the electrodes and the electrolyte that fills in the pores. Overall, the new supercapacitor exhibits a performance that is superior to that of one made of the same electrode materials but without the sponge.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. To demonstrate its performance, the researchers connected three of the supercapacitors to power a red LED for five minutes. They hope that this easily fabricated device could have applications where light-weight, low-cost energy storage devices are needed.”The electrodes developed are flexible and have high performance, so they have many potential applications, especially for bendable, wearable, and portable electronics,” Ma said. The researchers, led by Jun Ma at the University of South Australia, have published their paper on the kitchen sponge supercapacitors in a recent issue of Nanotechnology.Although this is not the first time that sponges have been used to make supercapacitors, the idea is still new and not widely used. The study is the first to use sponges as the substrate for a composite of two particular electrode materials: 2-nm-thick graphene platelets, and nanorods made from the conducting polymer polyaniline (PANi). Each material has its own advantages and disadvantages, but when combined they offer the best of both worlds due to their synergetic effects. While the graphene platelets offer high power density but low capacity, the PANi nanorods offer a much higher capacity but suffer from a lower electrical conductivity and other drawbacks.When combined, the two materials help to “correct” each other’s weakness, in a sense. The graphene platelets consist of multiple layers, but usually not all of them are accessible to the electrolyte, which limits capacitance. When PANi nanorods are grown on the surface of the graphene platelets, they act as nanospacers to enlarge the interlayer distance between the platelets to make full use of their storage ability. On the other hand, the highly conductive graphene platelets improve the conductivity of the nanorods by wedging open the PANi fibers to provide more interface with the electrolyte.”This work reports a novel design for the fabrication of supercapacitor electrodes by taking advantage of the synergy between cost-effective graphene plates, conducting polymers, and kitchen sponge electrodes, resulting in not only excellent capacitance and decent power and energy density, but high capacity retention over 12,000 cycles,” Ma told Phys.org.

Image: The eye of Saturn’s storm Citation: Scientists study the evolution of Saturn’s great storm of 2010-2011 (2016, August 5) retrieved 18 August 2019 from https://phys.org/news/2016-08-scientists-evolution-saturn-great-storm.html More information: — Kunio M. Sayanagi et al. Dynamics of Saturn’s great storm of 2010–2011 from Cassini ISS and RPWS, Icarus (2013). DOI: 10.1016/j.icarus.2012.12.013— Dynamics of Saturn’s great storm of 2010-2011 from Cassini ISS and RPWS, arXiv:1607.07246 [astro-ph.EP] arxiv.org/abs/1607.07246AbstractSaturn’s quasi-periodic planet-encircling storms are the largest convecting outbursts in the Solar System. The last eruption was in 1990. A new eruption started in December 2010 and presented the first-ever opportunity to observe such episodic storms from a spacecraft in orbit around Saturn. Here, we analyze images acquired with the Cassini Imaging Science Subsystem (ISS), which captured the storm’s birth, evolution and demise. In studying the end of the convective activity, we also analyze the Saturn Electrostatic Discharge (SED) signals detected by the Radio and Plasma Wave Science (RPWS) instrument. Explore further This series of images from NASA’s Cassini spacecraft orbiting Saturn shows the evolution of a great storm of 2010-2011. Credit: NASA/JPL-Caltech/SSI Saturn experiences quasi-periodic planet-encircling storms. The latest significant, well-observed storm started on Dec. 5, 2010 and lasted until the end of 2011. Events like storms can be identified visually and through radio noise; thus, instruments onboard Cassini such as the Cassini Imaging Science Subsystem (ISS) and the Radio and Plasma Wave Science (RPWS), allowed scientists to obtain high-precision measurements of these violent outbursts in the planet’s atmosphere.Recently, a team of researchers led by Kunio Sayanagi of Hampton University in Virginia, analyzed the data provided by ISS and RPWS to study the storm’s birth, evolution, and demise. ISS obtained wide-angle pictures of the storm with a resolution of 60 to 120 km per pixel to study the vertical cloud structure. The instrument also allowed the team to measure cloud motions in order to reveal the atmospheric dynamics of the storm region. RPWS provided crucial information about the configuration of Saturn’s magnetic field, ionosphere, plasma, and lightning from the planet’s atmosphere.”We analyze Cassini ISS images and RPWS data to investigate the temporal evolution of the 2010-2011 planet-encircling storm. (…) Our study analyzes images acquired using the wide-angle camera’s CB2 (750 nm), MT2 (727 nm), and MT3 (889 nm) filters to study the vertical cloud structure. (…) We also present analysis of RPWS data that shows near-simultaneous coverage of the end of the convecting phase of the storm,” the scientists wrote in the paper.According to the research, the storm erupted out of a previously known feature called the String of Pearls (SoPs)—a chain of about 26 cyclones located at 33° N planetocentric latitude. Afterwards, the outburst grew and engulfed the entire latitude zone. The scientists noted that on January 11, 2011, the dimensions of the storm’s “head” were 9,200 km and up to 34,000 km in the north-south and east-west dimensions, respectively. They also emphasized that this storm spawned the largest tropospheric vortex ever seen on Saturn.”On January 11, 2011, the anticyclone was sized 11,000 km by 12,000 km in the north-south and east-west directions, respectively. (…) With the east-west diameter of 12,000 km, the new anticyclonic vortex became greater in size than any tropospheric vortex previously seen on Saturn. The rapid growth and shrinkage of the new anticyclone is in stark contrast to the steadiness of anticyclonic vortices on Jupiter,” the paper reads.The study notes major changes in the storm dynamics after June 20, 2011 when the storm’s head collided with the anticyclone after the anticyclone’s longitude trailed 360° longitude behind the core. After this collision, the storm’s convective activity displayed a major decline. However, the storm left the region between 25°N and 40°N in a highly disturbed state. According to the paper, these atmospheric events also altered the zonal mean wind profile of the storm latitudes.The researchers expect that the storm of 2010-2011 will have lasting effects on Saturn’s northern hemisphere.”The aftermath of the latest storm should have an effect that may last for up to a decade, and a continuing monitoring of Saturn from the orbiting vantage point of Cassini spacecraft should reveal further details of the dynamic event,” the scientists concluded. © 2016 Phys.org (Phys.org)—The NASA/ESA Cassini spacecraft has made plenty of groundbreaking discoveries, outstandingly improving our knowledge of Saturn and its moons, including our understanding of violent processes in the atmosphere of our solar system’s second-largest planet. Now, a new research paper published July 26 on arXiv.org, which details the dynamics and evolution of Saturn’s great storm of 2010-2011, marks another important study based on the data provided by Cassini’s scientific instruments.

More information: G. W. Biedermann et al. Atom Interferometry in a Warm Vapor, Physical Review Letters (2017). DOI: 10.1103/PhysRevLett.118.163601 . On Arxiv: https://arxiv.org/abs/1610.02451ABSTRACTWe demonstrate matter-wave interference in a warm vapor of rubidium atoms. Established approaches to light-pulse atom interferometry rely on laser cooling to concentrate a large ensemble of atoms into a velocity class resonant with the atom optical light pulse. In our experiment, we show that clear interference signals may be obtained without laser cooling. This effect relies on the Doppler selectivity of the atom interferometer resonance. This interferometer may be configured to measure accelerations, and we demonstrate that multiple interferometers may be operated simultaneously by addressing multiple velocity classes. © 2017 Phys.org (Phys.org)—A team of researchers at Sandia Labs in the U.S. has developed a type of atom interferometer that does not require super-cooled temperatures. In their paper published the journal Physical Review Letters, the group describes the approach they used to overcome the main hurdles to warm interferometry and the ways in which their new device can be used. Carlos Garrido Alzar with Sorbonne Université offers a commentary piece on the work done by team in the same journal issue and offers a descriptive analogy of the device they created.

Credit: arXiv:1610.02451 [physics.atom-ph] There are two kinds of interferometers—optical and atom. Both are precise measuring devices that operate by measuring interference fringes that are produced when a beam is cut in half and both halves are allowed to proceed for a short distance before being recombined—thus recording the information generated due to interference, such as from gravity. To date, atom interferometers have required very cold temperatures to operate—the cold slows the range of velocities of a collection of atoms to increase the signal that occurs at the machines’ output. It also helps to keep the atoms under study close to one another, which improves precision. Atom interferometers do their measuring by using laser beams to split the beam under study. In this new effort, the researchers have come up with a new kind of atom interferometer that works without the need for very cold temperatures.As the researchers note, the development of the new interferometer required overcoming two main obstacles—the first was to greatly reduce spin flipping due to collisions with the chamber walls. The team got around this by developing a special coating for the chamber that dramatically reduces such flipping. The second problem involved developing a way to align the weak laser that detects interference fringes and the strong laser used as the interferometer. They solved this problem by using two counter-propagating probe beams to measure signal differences. The result was an atom interferometer that was not as sensitive as those that require extreme cold, but one that can acquire data faster, can be ported more easily, and is able to measure a wider range of accelerations.Garrido Alzar describes the difference between the cold and warm approach as the difference between a device that operates much like as laser versus one that works using light from a regular white light bulb.

Nearly 30 years ago, a mathematician and a psychologist teamed up to explore one of life’s enduring mysteries: What makes some marriages happy and some miserable? The approach also proved to be shockingly accurate at predicting which couples would divorce. It was a match made in heaven. The psychologist, John Gottman, wanted to craft a tool to help him better counsel troubled couples. The mathematician, James Murray, specialized in modeling biological processes. The pair decided to create a mathematical model to quantify how couples interact and influence each other during an argument. The results helped Dr. Gottman visualize the dynamics of a marriage and measure the impact of therapy. “We got actual numbers we could compute,” Dr. Gottman said. “We could see how the partners influence each other.” Read the whole story: The Wall Street Journal
Many times, the answer is yes. There was a person — or many people — who spotted a looming crisis and tried to warn those in power. So why didn’t the warnings lead to action? After a disaster happens, we want to know, could something have been done to avoid it? Did anyone see this coming? This week on Hidden Brain, we look into the psychology of warnings. Plus, we’ll learn why ordinary people can sometimes do a better job of predicting the future than the so-called experts. They’re the subject of the book Superforecasting: The Art and Science of Prediction, co-authored by psychologist Phil Tetlock and journalist Dan Gardner. Read the whole story: NPR
Fashion Design Council of India’s (FDCI) quest for picking out new talents shows no signs to ebb. This time, the fashion body tied up with Cotton Council International for a contest to pick out young designers. They got together in the Capital recently to announce the names of five young designers who will progress to the final round of ‘Let’s Design Contest’. Vimal Abinash, Sanya Mukesh Jain, Gurman Singh Chawla, Padmaraj Keshri and Harjosh Singh Gioraya will progress to final round from Delhi regional eliminations. Their works have been selected from over 2,00 entries. They will join seven more young talents from Kolkata and Mumbai.On the judging panel were young designers Samant Chauhan and Nitin Bal Chauhan who judged the entries and selected the regional winners who all had to craft their designs using cotton. The 12 candidates from around India will be invited to Delhi, where they will face a series of design challenges. The winners will receive Rs 1 million and the chance to present their collection at the Fashion Week.
A sultry evening in Delhi was proof. Shiro at Samrat Hotel opened its doors for intellectuals, book lovers and friends as the black and red interiors played host to Sreemoye Piu Kundu’s book Sita’s Curse (Hachette, Rs 350) launch in the Capital. Apsara Reddy, actor Adil Hussain and Mahabanoo Mody-Kotwal (of the Vagina Monologues fame) along with Kundu opened the evening with discussions about sex, sexuality and desire before they read parts of the novel and engaged in some very riveting conversations with the packed house. Also Read – ‘Playing Jojo was emotionally exhausting’Sita’s Curse tells the story of Meera who, after the death of her twin brother and a rather unhappy marriage, manages to find desire her way. What ties you down to the novel is the vivid imagery and the stunning words Kundu uses to express Meera’s wants. Wants and needs are a world apart and in the domain of desire, the former rules supreme. Kundu revealed that she crafted Meera along the lines of this beautiful, sensuous woman she used to see in a chawl in Mumbai, everyday, on her way to office. Mumbai floods hit and Kundu never saw Meera again, but Meera’s sad melancholic eyes plagued her and eventually came Sita’s Curse. Also Read – Leslie doing new comedy special with NetflixThe panelists discussed at length that in India, desire and women were divorced concepts and how more often than not, a woman loses her sexuality once she is married. A married woman ends up prioritising her husband, in-laws, kids and her house over herself and somewhere a beautiful woman just vanishes into nothing. Sita’s Curse is a rescue from that. Kundu, without a doubt, is the first of the gutsy breed of writers I spoke of in the beginning. Her language of desire started with Faraway Music and has gained a more sensual font in Sita’s Curse. Published by Hachette this book is now in its second print run and roaring ahead. The country does not have much erotic English literature to talk of and most books, if they exist and written in rather distasteful prose – we could well call Sita’s Curse a first for many other reasons including the genre it carves out for itself. The enthusiastic audience agreed whole heartedly with the discussions about women setting their minds on the path to find desire and accept that all of them deserve to be desired. A Meera in all of us. Pick up the book, you won’t regret it.

Despite being an independent woman, there is a constant fear of being strangled by a group of hooligans on grounds of morality. Living in the largest democratic nation in the world has its own perils.” Also Read – Add new books to your shelf2017 witnessed a case in Kerala where a man was attacked, filmed and mocked on social media by culture vigilantes. The severe crime that he committed was that of hanging around with a female friend on Valentine’s day. Later, the guy committed suicide because of humiliation. Similar cases have been reported in Uttar Pradesh, Maharashtra, and Karnataka., where young couples were forcibly married, and publically thrashed after blackening their face and shaving off their heads.

It was the first time I experienced the sight of an unruly mob moral policing the young couples visiting the park just like us (we never observed any obscenity or intimacy amongst the couples except a few holding hands). Some even had a hard time explaining that they were siblings until their parents confirmed on call or showed up in some time. It obviously instilled a sense of fear inside our teenage minds for those aggressive men.” “Years past that incident, every successive year I see news flooded with such mishappenings on Valentine’s day. What I still don’t understand is, how sweeping away all the love (just the unmarried ones) from the streets, parks, and cafés on one single day will leave us with a more cultured India, where love between a male and female can only happen to occur if you tie knots; else it becomes a western induced illegal salacious affair,” he further said. Zeeshan Kaskar, another student who is from JMI revealed a similar problem faced by him while he was sitting with a female friend in his hometown. According to him, “the problem is not just pertinent to metropolitan cities, it’s there throughout the country.” A student from Aligarh Muslim University anonymously expressed his opinion on the issue. “The fuss created by anti-Romeo squads in Uttar Pradesh last year, has made star-crossed lovers run for cover.”A law student from UP, however, expressed contentment by questioning the preachers of morality: “If a girl has been raped, nothing happens, but if a girl is voluntarily roaming with someone, some groups ‘freak out’. I believe they are assuming some authoritative power, which even the Constitution doesn’t assign them,” he further added.What’s more shocking is when an elite educational institute supports and promotes such a regressive ideology. At present, it is Lucknow university making headlines for issuing an advisory, telling students not come to the campus on Valentine’s day.Condemning any such activity, Mohammad Anas, a postgraduate student studying literature feels that “love cannot be chained at any cost, and hence, moral policing will only add more poison to polluted air of the present day. People are against love since the very beginning of the human existence but love manages to flourish in every time.”Indeed that gives out a positive vibe amidst all the negativity prevailing in the ambience these days. Akshay, a young man working as a PRO gives a blunt suggestion at the end note. “Instead of stopping something happening with the consent of both the ends, try focusing upon hunting down the harassers and molesters this year. Popularity can be gained through good things as well,” he said.
Kolkata: Trinamool Congress supremo Mamata Banerjee has given a week’s time to her party workersand leaders who want to join other parties. “We do not want traitors. Those who want to join other parties are free to go and I give them seven days’ time. I will run my party with freshers,” she said, while addressing a meeting of the party workers at Kanchrapara on Friday afternoon. Without naming BJP leader Mukul Roy she said: “A traitor has joined BJP. It is my mistake. My party colleagues had told me about him but I did not listen to them and did not take any action on humanitarian ground. Those who want to leave the party are free to go. That will purify our party. Bring the unemployed youths into our fold and they will do the work seriously. Rest assured I will look after them,” she said.

I have asked police to take stern action against those who will try to create disturbance in the area,” Banerjee added. The Trinamool supremo urged party workers to unite against the onslaught of BJP. “BJP is trying to divide the society. They went to the Hindu areas and spoke against the Muslims and vice-versa. They went to the Christians and spoke against the Sikhs. They even divided the SCs and STs. They incited the Biharis against the Bengalis. I am not going to tolerate this. I urge all my party workers to foil this attempt to divide our society,” she added.

Banerjee alleged that BJP has spent Rs 27,000 crore to win the elections. “They have spent money to buy the voters. They have spent money to circulate lies on social media. We do not have money but we will fight it out,” she told her party workers. Coming down heavily on media, Banerjee said: “It has become a trend to criticise me on television. I do not mind. But on many occasions false news has been shown just to malign Bengal. This is most unfortunate,” she said.
Astronaut Harrison “Jack” Schmitt, who also has a Ph.D. in geology from Harvard University, landed on the Moon along with Eugene A. Cernan on December 11, 1972, and began collecting rock samples. While other missions had collected rocks, no one had been familiar enough with geology to know what types were important.With an expert picking the specimens, more stories could be told of the Moon’s history.Astronaut Harrison H. Schmitt.During the mission, Schmitt unintentionally breathed in some lunar dust and for the rest of the day exhibited signs similar to hay fever or an allergy — sneezing and watery eyes.In 1972, the NASA doctors thought he was allergic to the Moon.The ground crew at NASA’s John F. Kennedy Space Center were highly amused and, according to Mental Floss a member of mission control, Joseph Allen, remarked, “It’s funny they don’t check for that. Maybe that’s the trouble with the cheap noses, Jack.”Apollo 17 landing site, photographed in 2011 by Lunar Reconnaissance Orbiter.Moondust is composed of the remnants of micrometeorite impacts that remain sharp due to the lack of erosion because of no air or water movement on the Moon.Small bits of iron are also in the dust, giving it properties similar to a blanket with static cling; the dust is attracted to everything.It gets stuck in equipment, on the folds of spacesuits and, according to the director of the Planetary Geosciences Institute, Larry Taylor, in a 2008 interview at the Soil Science Society of America, “The dust was so abrasive that it actually wore through three layers of Kevlar-like material on Jack’s boot.”Schmitt collects lunar specimens during the Apollo 17 mission.When the astronauts left the earth, their spacesuits were clean and white but when they returned it looked as though they had been playing football in the dirt. With no place to shake out their suits before returning to the lunar module, moon dust quickly coated the interior of the module. Cernan and Schmitt were breathing it and getting it in their mouths.Since then, NASA has done extensive studies on the effects of moon dust. In the spring of 2018, GeoHealth conducted tests on man-made moon dust using similar materials of volcanic ash, lava flows, and an artificial powder to simulate the sharp particles.Apollo 17 lunar rover at its final resting place on the Moon. The Surface Electrical Properties (SEP) receiver is the antenna on the right-rear of the vehicleThe dust was able to embed itself into the lungs’ interior causing a type of respiratory disease similar to Black Lung Disease experienced by coal miners.According to the test, the dust caused cell damage down to the DNA level and cell death, as well as hypertension which many of the Apollo astronauts are now experiencing.Apollo 17: Inside the Lunar Module training simulator, Gene Cernan drapes the cords for the LM cabin utility lights on the handle of the rendezvous hatch. The two utility lights are just to the right of Jack Schmitt’s right hand and are attached to the Alignment Optical Telescope (AOT) guard with clamps.The findings have led NASA to begin development of ways to combat the lunar space dust.The Apollo 17 mission aimed for the Taurus-Littrow Valley because of the varied geological content and the proximity to a crater that has produced volcanic rock in the past.Lunar Regolith collected during Apollo 17.

Cernan holds the distinction not only of being the last man on the moon but also of being the only astronaut who broke a rover on the moon.He and Schmitt were able to repair the fender that broke when a hammer in one of Cernan’s pockets caught the back of the right fender and pulled it off.This is Gene Cernan’s photo from the end of the north arm of the SEP transmitter array, showing Jack Schmitt on the south arm beyond the transmitter.Without a fender, so much moon dust would have been thrown up it would have been nearly impossible to see where they were going, and the equipment they were carrying would have been destroyed.Initially, they tried duct tape, one of NASA’s required items on the official stowage lists, but the dust kept it from adhering well.Mission Control came up with a solution using four maps held together with duct tape (before they were exposed to dust) which were then clamped to the end of the broken fender.Read another story from us: Apollo 11 Astronauts were Quarantined for 21 Days after Returning from the MoonThe solution worked and the mission was completed successfully.
