(Phys.org)—Researchers at the Keck Institute for Space Studies have released a paper outlining a proposal to send an unmanned spacecraft into deep space to capture an asteroid and return it as a Near Earth Asteroid (NEA) orbiting the moon. In putting together the paper, the team at Keck worked with several NASA agencies, universities and private groups with the aim of discerning the feasibility of such a project and then outlining how it might come about. In their paper, the Keck team proposes using an Atlas V rocket to launch a craft that once in space would be slow moving, powered by solar heated ions. Once the target is reached, a bag would be opened that would engulf the asteroid – which would likely be no bigger than 7 meters wide – then drag it back and place it into orbit around the moon. Such a mission, the researchers suggest, would likely take six to ten years depending on the distance to the asteroid and cost in the neighborhood of $2.6 billion, which isn’t much more than the Mars Curiosity rover mission.Currently NASA’s only officially planned manned space mission is called Orion and its aim is to send a craft around the moon. President Obama has also suggested that he would be open to sending a manned mission to an asteroid. By first moving an asteroid to moon orbit, it appears NASA could accomplish both the Orion objectives and landing a manned craft on an asteroid in a single mission. Doing so with an NEA would also be far less risky – sending astronauts into deep space would expose them to long term radiation and would put them beyond the limits of a rescue mission should something go wrong. More information: .via Newscientist The researchers say that putting an asteroid in orbit around the moon has become feasible in recent years due to three main developments: the ability to find and track small asteroids, the capability of building spacecraft that have the ability to fly to an asteroid and bring it back and finally, the plans by several groups to have a manned presence in the vicinity of the moon during the time proposed (sometime in the 2020s) for the capture of the asteroid. Putting an asteroid in orbit around the moon would allow for much more convenient study and also open the door to mining possibilities. Explore further Asteroid return mission concept. Return flight time of 2 to 6 years depending on the asteroid mass.

Ice cores store atmospheric bubbles from a million years ago

first_img © 2015 Phys.org Credit: Newcastle University Explore further (Phys.org)—A team of researchers with members from Princeton University, the University of Maine and Oregon State University has found that greenhouse gasses a million years ago, were only slightly higher than they were between 450,000 and 800,000 years ago. In their paper published in Proceedings of the National Academy of Sciences, the team describes their study of the newly retrieved ice cores and how it is helping to better understand the changes to the Earth’s ice ages. Journal information: Proceedings of the National Academy of Sciences More information: Atmospheric composition 1 million years ago from blue ice in the Allan Hills, Antarctica John A. Higgins, DOI: 10.1073/pnas.1420232112AbstractHere, we present direct measurements of atmospheric composition and Antarctic climate from the mid-Pleistocene (∼1 Ma) from ice cores drilled in the Allan Hills blue ice area, Antarctica. The 1-Ma ice is dated from the deficit in 40Ar relative to the modern atmosphere and is present as a stratigraphically disturbed 12-m section at the base of a 126-m ice core. The 1-Ma ice appears to represent most of the amplitude of contemporaneous climate cycles and CO2 and CH4 concentrations in the ice range from 221 to 277 ppm and 411 to 569 parts per billion (ppb), respectively. These concentrations, together with measured δD of the ice, are at the warm end of the field for glacial–interglacial cycles of the last 800 ky and span only about one-half of the range. The highest CO2 values in the 1-Ma ice fall within the range of interglacial values of the last 400 ka but are up to 7 ppm higher than any interglacial values between 450 and 800 ka. The lowest CO2 values are 30 ppm higher than during any glacial period between 450 and 800 ka. This study shows that the coupling of Antarctic temperature and atmospheric CO2 extended into the mid-Pleistocene and demonstrates the feasibility of discontinuously extending the current ice core record beyond 800 ka by shallow coring in Antarctic blue ice areas.center_img The cores were taken from a part of Antarctica known as Allan Hills—there unique geography has caused glaciers sliding down mountains to slide upwards for a bit. Additional erosion due to wind and precipitation has caused very old (blue) ice to lie close enough to the surface to be extracted via core drilling. Dating has shown the ice to be approximately one million years old, which means the air bubbles trapped inside are the same age as well—the oldest found so far. Those air bubbles offer scientists an opportunity to measure the amount of different gasses in the atmosphere from that time period, and it is helping, the team suggests, to gain a better handle on the changes to cyclic ice ages.Prior study has shown that before a million years ago, the Earth experienced ice ages approximately every 40,000 years, but after that the cycle grew longer, to approximately 100,000 years and scientists want to know why—they suspect it has to do with changes to the ratios of greenhouse gases—most specifically carbon dioxide. That is where the air bubbles in ice core samples come in, they offer direct evidence of carbon dioxide levels. The latest samples show that there were not major swings in greenhouse gas levels at that time, but more ominously, that carbon dioxide levels never rose above 300 ppm over the past million years, until the twentieth century—right now the level is approximately 400 ppm.The record setting ice cores do not actually answer any real questions about the cyclic nature of ice ages, the researchers acknowledge, but instead add another chapter to a growing body of knowledge—a suggestion that there is indeed a strong correlation between carbon dioxide levels and glacial cycles.

Entering the world of a familiar stranger

first_imgDrawing a parallel between the bustling metropolises of San Francisco and New Delhi, with a special focus on the issues of urban alienation and human angst, a new show at Khoj Studios titled Frozen World of the Familiar Stranger is being hosted by Khoj International Artist’s Association in collaboration with Kadist (an experimental arts space) in San Francisco. It is a group show of video installations, performances and artworks featuring ten Indian and international artists. Also Read – Add new books to your shelfSays Sitara Chowfla, curator, Khoj Studios: “The name of the show is borrowed from American social psychologist Stanley Milgram’s 1970’s essay naming and elaborating on this theory. Milgram wrote about the idea of urban anonymity and the idea of feeling estranged from our fellow city dwellers.His writing and experimentation on this subject was a major inspiration to our curatorial process, and we were struck by how salient the concept read now, decades later. We were inspired to revisit his observations in some symbolic way, through the lens of these brilliant artists. We are witnessing similar issues of urban alienation in big cities like Delhi and San Francisco. Look at how in these long queues in postdemonetization, we might know the next person in the queue as a familiar neighbor and yet we are filled with anger for being behind them.  Also Read – Over 2 hours screen time daily will make your kids impulsive“Or take traffic jams. We might not know the person in the next car but are still filled with hatred for an unknown person. Frozen World of the Familiar Stranger reflects upon the uncanny sensation of the ultra-modern global megalopolis, and the increasing sense of alienation we encounter in our flattening world.Through works exploring isolation, confinement, collapse, transience, anxieties, and fantasies of inhabiting collective urban space, Frozen World offers an almost satirical point of view on the human condition and what it means to be alive together in the present, and in the constructed future. ” The featured artists are Cao Fei (China), Farideh Lashai (Iran), Himali Singh Soin (India), Ho Tzu Nyen (Singapore), Kartik Sood (India), Maya Watanabe (Peru), Rachel Rose (USA), Sahej Rahal (India), Steffani Jemison (USA) and Tejal Shah (India). It is co-curated by Sitara Chowfla (Khoj) and Heidi Rabben (Kadist).Chinese artist Cao Fei is showing a video work titled La Town (2014) that places us in the midst of an envisaged, incipient, either recently past or impending catastrophe. Using tiny models, the artist creates a world suspended somewhere between reality and dystopia, a ‘world community’ in miniature, where a happy coexistence is no more than a promise, a brief interlude in the unrelenting tide of a violent, destructive history. The wall-based sound and projected animation on painting work by Iranian artist Farideh Lashai (b. 1944, Iran – d. 2003) is titled Keep your Stomach Empty; That  you Mayest Behold Therein the Light of Interior (Sani-ol-Molk), 2010. Inspired by a 19th century painting by the legendary Iranian artist Sani-ol-Molk, the work symbolizes a narrative of fear and of resistance, which are recurring themes in Lashai’s work, and life. Indian artist Himali Singh Soin is showing a video work titled ‘Radar Level’, the background footage of which was shot in Mongolia on location where the first dinosaur egg was found. Soin will also be conducting a series of performances based on her video work on December 17 (5 PM) and January 11 (5 PM).Singapore-based Ho Tzu Nyen is showing a video work titled ‘The Cloud of Unknowing’, 2011 that is titled after a fourteenth century mystical treatise on faith, where the cloud is paradoxically a metaphor for both an impediment to, and reconciliation with, the unknown or the divine experience. Indian artist Kartik Sood’s mixed-media work consisting of two videos, as his work explores the character’s experience of loneliness in an urban environment. Peruvian artist Maya Watanabe is showing a video work titled El Contorno (Contour, 2011). American artist Rachel Rose has a video work on display titled ‘Sitting, Feeding, Sleeping’, 2013. It takes us on a very particular journey through contemporary constructions created around different life forms, from medical breakthroughs in a cryogenics lab to basic scientific facts in a robotics perception lab, to animal care within zoos across the US. Sahej Rahal has on display photographs that document performances titled ‘Keeper’ (2015) and ‘Katabasis’ (2011). American artist  Steffani Jemison is showing a video work titled Escaped Lunatic, 2010-2011, in which a steady stream of figures run across the screen, sprinting, jumping, and rolling through the streets of Houston. The work is part of a trilogy that borrows its narrative structure from early-20th-century cinema. Indian artist  Tejal Shah has two video works – titled Between the Waves, Channel II – Landfill Dance, 2012) and Between the Waves, Channel IV – Moon Burning, 2012 – and a mixed media collage of digital prints on archival paper titled Between the Waves Collages – Inner, 2012. For this project, Shah creates sensual, poetic, heterotopic landscapes within which they place subjects that inhabit personal/political metaphors – embodiments of the queer, eco-sexual, inter-special, technological, spiritual and scientific.last_img read more
