New Craters Found on Mars

first_imgOrbiters can count new craters forming on Mars, refining cratering rates.  One spectacular new crater has appeared since 2010 with vivid rays.The BBC News published a photo of the new crater taken with the HiRise camera on board the Mars Reconnaissance Orbiter.  Seen in false color, with its 9-mile-long rays surrounding a 100-foot-wide crater , it looks like a blue starburst.  The crater formed sometime between July 2010 and May 2012; the hi-resolution photo was taken last November.  This and other craters lead scientists to estimate that “impacts producing holes at least 3.9m (12.8ft) in diameter occur at a rate exceeding 200 per year across the planet.”  Astrobiology Magazine also announced the crater.  See also 5/21/13.Mars scientists never cease wondering if water flowed on Mars, and if so, whether life appeared. teased with a headline, “Ancient Mars May Have Been Habitable for Hundreds of Millions of Years,” based on the supposition that clay-rich minerals at the rim of Endeavor Crater, found by the Opportunity rover, suggest that neutral-acidic water once existed there.  Astrobiology Magazine called the outcrop “livable mud.”  Meanwhile, on the other side of the planet, the Curiosity rover supposedly found a dry lake bed.  Mission scientist John Grotzinger introduced five papers in Science about Mars habitability.  Exercising some restraint on imagination, he agreed, “These results demonstrate that early Mars was habitable, but this does not mean that Mars was inhabited.”One real-Mars factor that cannot be ignored is the radiation environment.  The top few meters of Mars’ surface is exposed to ionizing radiation, likely to degrade organic molecules.  From measurements reported by others in the special issue, Grotzinger said, “Extrapolating these rates over geologically important periods of time and merging with modeled radiolysis data yields a predicted 1000-fold decrease in 100–atomic mass unit organic molecules in ∼650 million years” – just 14% of Mars’ assumed age.  One paper proposes that mudstone with organics was buried till recently exposed; that’s about the best hope for possible life to escape the radiation barrage.  “Earth’s thick atmosphere and magnetic field greatly reduce incoming radiation,” Grotzinger noted.Evidence of flowing water on the rims of craters has been hard to prove, Science Daily reported.  The “recurring slope lineae” keep reappearing in the Martian summer, but scientists cannot rule out non-watery processes for their formation.There is life on Mars now, if you can include the most Mars-like environment on Earth.  The Conversation tells about volunteers who are working in simulated Martian conditions out in a remote stretch of Utah desert near Hanksville.  Ashley Dale tells about his experiences as crew commander in a 14-day experiment to prepare human beings for the rigors of a trip to the red planet.  As visionary as such a trip sounds, reality checks will be needed.  “I had to keep a calm head and remind myself of the expedition’s priorities,” he said; “Human ingenuity has been perfecting the technology we will need on Mars, but what we can’t do is eliminate human follies.”Update 2/13/14: Astrobiology Magazine posted a graph showing that the daily Martian radiation dosage exceeds the annual limit for a Department of Energy Worker.  What does this do for life?  If it’s in the Martian soil within a meter of the surface, “gamma rays and neutrons are easily capable of breaking molecular bonds in the soil, destroying evidence of past life, as well as any life that may be presently trying to survive there.”Human follies, alas.  They are evident right here, in the vain imaginations of astrobiologists.Let’s do a simple back-of-the-envelope calculation of cratering on Mars from the figure given: at least 200 new impacts per year 12 ft across or more.   That should yield 900 billion craters over the lifetime of Mars – close to a trillion.  Assuming a fraction of those would be large enough to loft debris to form secondary craters, and some of those could create orbiting bodies that would fall later, that total seems unreasonably high.  The same rate would produce over a million craters in just 6,000 years – plenty, but credible.  If anyone would like to refine these estimates, they would need to consider the rate of erasure of craters by dust storms and other impacts, and factors that could vary the impact rate from a steady state.  The rate we measure today, for instance, may not reflect rates in the past.  Planetary scientists frequently propose a “Late Heavy Bombardment” of large impactors, for instance, but such hypotheses are speculative (1/09/12).

SA launches schools football WC

first_img13 May 2008The Moletsane Sports Complex in Soweto, to the southwest of Johannesburg, was awash with activities last Saturday, with the official launch of the South African Schools Football World Cup Partnership.The partnership is an initiative lead by the Department of Education, the Department of Sport and Recreation, the 2010 Local Organising Committee (LOC) and the South African Broadcasting Corporation (SABC) in an effort to educate and get some 12-million South African school pupils – both boys and girls – excited about hosting the 2010 Fifa World Cup.Education Minister Naledi Pandor, Deputy Sport and Recreation Minister Gert Oosthuizen, LOC chairman Irvin Khoza, LOC communications director Tim Modise, Bafana Bafana legend Phil Masinga, various government officials and SABC representatives attended the launch.The launch of the partnership on 10 May coincided with the election of Nelson Mandela as South Africa’s first democratic president in 1994, and music, dance and cheer was the order of the day as groups from participating schools shared the stage and rendered cultural items to the delight the crowd.Confederations Cup, World Cup inspirationSaturday’s launch saw the start of the first phase of the competition, with the tournament being rolled out in two phases. The first phase will be organised along the lines of the Confederations Cup and the second phase the actual World Cup.For each of the phases, the schools that participate will assume the identities of the participating countries, with all schools being encouraged to fly the national flag, sing the national anthem and engage in other activities, such as preparing the national food of the country they represent.The participating schools last week were Lavela Secondary, Emdeni High School, Zithathele Primary School, Ekuphumeleleni Primary, Progress, Winnie Ngwekazi High, Moletsane Secondary and Kliptown Secondary.“The World Cup is going to involve all South Africans, Africans and particularly South African children,” said master of ceremonies Modise, adding that the partnership gave students and opportunity to participate actively in the World Cup.Diverse culturesPandor meanwhile made an avid appeal to all participating schools pupils to learn as much as they can about the countries they will be representing in the tournaments.“In this way we are then preparing our young people to enjoy the World Cup with a key understanding of the diverse world we leave in, we are encouraging young people to know about other countries and their cultures,” she said.Pandor added that the initiative was also aimed at luring school children away from the streets and inappropriate habits, and encourage them to engage in healthy lifestyles.“The launch of this partnership in Soweto must motivate us to use school sport to encourage physical activities and healthy lifestyles,” she said. “The competition must also remind us about our commitment to the HIV/Aids awareness campaign, to our commitment to anti-doping and to our commitment to prevent substance abuse among young people and our citizens generally.”Spreading the messageKhoza said the 12-million school children being targeted by the initiative would help spread the message about the World Cup to families and communities.“Consequently schools have been identified as a primary vehicle to take the Fifa 2010 World Cup messages not only to children, but indeed to families and to communities of South Africa and also the African continent,” he said.The 2010 Fifa World Cup School Campaign is built on three key pillars namely education, development and participation.“The other goals of the campaign are to ensure the development and implementation of integrative educational campaign aiming at preparing and educating learners and teachers about all aspects of the Fifa World Cup,” said Khoza.Gert Oosthuizen encouraged fair play throughout the competition and urged learners to stay away from illegal performance enhancers and drugs.“It is a natural attribute of human beings to compete, but the way in which we compete tears us apart, we need to apply the rules of the game and not cheat,” he said. “We need to ensure that we do not take performance enhancing substances and cheat in a calculated and manipulative way, we also need to say Ke Moja no to drugs.”Source: South Africa 2010last_img read more

Itlhabolole: beauty from waste

first_imgA pair of shoes created from waste by Itlhabolole Waste Management, a self-help project in North West province. (Image: North West Craft and Design Institute) MEDIA CONTACTS •Margaret Khambule Itlhabolole Waste Management +27 73 648 7200 •Potlako Ntlatleng North West manager National Development Agency +27 18 392 6892RELATED ARTICLES • Voluntourism: See SA, do good • Greening it up in Cape Town • Food security starts at home Bongani NkosiSomewhere in South Africa, in some little-known village, waste is being turned into beautiful income-generating objects.A band of motivated women in Ikopeleng village, in the North West province, are leading a groundbreaking project, aptly called Itlhabolole Waste Management. They turn bin-destined waste into stylish clothing and other indoor designs.Ithlabolole (Setswana, meaning “develop yourself”) produces trendy ladies’ bags, traditional Tswana clothing, shoes, plastic wreaths, dustbins, peg holders, mats and placemats from plastic.“We collect dirty plastics to create beautiful artefacts,” says founding member Margaret Khambule. “The people we work with are very passionate about the project.”Itlhabolole was started in 2000 by a group of 21 people, mostly women. In 2005 the group received their biggest funding to the tune of US$51 200 (R387 700) from the National Lotteries Board.Also in 2005, it was a recipient of a $2 640 (R20 000) donation from the Department of Trade and Industry (DTI) through its Khula Enterprise, which facilitates access to funding for small and medium businesses. The Small Enterprise Development Agency also gave Itlhabolole $6 600 (R50 000) in that year.“This is a project that shows that women are an economic power in rural areas and are determined to fight poverty…,” said then DTI deputy minister Elizabeth Thabethe at the South African Women Entrepreneurs Network imbizo in 2005.The funds catapulted Itlhabolole to a prolific and stable organisation that is able to generate income for its members. Today the cooperative consists of 18 people, 14 of whom are women and two are youth.“We sell our products and we also do exhibitions across the country. We try to boost our families,” said Khambule. “The project is not exactly big; we are just trying to sustain it.”The DTI’s support for the group has been quite commendable, said Khambule. The National Development Agency (NDA), which is mandated by the government to fund community projects, has been funding Itlhabolole for the past two years. “The DTI and NDA are helping us a lot.”Growth and successWithin just a year of its launch in 2000 the women were able to build their project’s headquarters in their village.The cooperative continues to enjoy its success and growth. Its impressive showing at Decorex Joburg, an expo that took place in the city in August, secured Itlhabolele a deal to showcase its products to Germany in an exhibition in 2010, and a chance to get its products into German markets.The annual Decorex event, a convergence of local and international designers, showcased chic indoor and outdoor designs.Itlhabolole received an overwhelming response at Decorex and its products were sold out within two days. The project took home a silver medal in the Best Product category.“This recognition is not only for the work that this organisation is doing, it also confirms for the women of Itlhabolole Waste Management that life is what you make of it,” said Potlako Ntlatleng, NDA North West provincial manager.“In a time when concern over the environment is gaining much attention, a small village in a corner of South Africa is creating wealth out of the waste that litters our streets,” Ntlatleng said.The group has established a strong client base in Johannesburg, Cape Town, Kimberley and Botswana. “We also trained groups of people on recycling in Kimberley and Botswana,” said Khambule.More than just a businessItlhabolole is more than just a business project; it is also an NGO. As part of its community work the group embarked on a cleaning campaign in Ikopeleng village on 2 October.Khambule said the campaign, which was also supported by their local municipality, was quite a success. She said they are on a drive to convince the government to lead clean-ups in villages. “We want to encourage the government to take part in these campaigns.”Khambule added that they were looking ahead to the 2010 Fifa World Cup, when millions of visitors are expected to flock to South Africa. “The country must be beautiful,” she said.Environmental responsibilityTeaching school-going youth about the necessity of a clean environment has also become the group’s work. They visit schools to drive a clean environment message. “It must ring in their heads that we need a clean environment,” said Khambule. Farming could also become Itlhabolole’s next major success. The group has recently received a piece of land in their village and plan to use it to grow their gardening business.At present they sell their vegetables in surrounding villages in the North West province. But the ultimate dream is to be able to supply major markets. “I dream about the farm becoming big, if we could just have a bigger market,” said Khambule.She said they continue to receive support from other government ministries, such as the Departments of Agriculture as well as Arts and Culture. The latter department recently provided art and administration learnerships for Itlhabolole.last_img read more

Spikes to be Placed on Toll road Off Ramps

first_imgSpikes are to be placed on the toll road off ramps, to deter motorists from reversing onto the road.Regulations facilitating the move were approved by the House of Representatives on February 26.A spike is used to impede or stop the movement of wheeled vehicles by puncturing their tyres.Opening the debate, Minister of Transport, Works and Housing, Dr. the Hon. Omar Davies noted that over time, the toll road has become plagued by motorists who, in an effort to avoid the toll fees, reverse onto the slip roads adjoining the toll roads.“This has created great cause for concern due to injuries, damage and fatalities from the collision between these motorists and unsuspecting legitimate users who are exiting the toll road. The last fatality occurred on 22 August 2011,” Dr. Davies said.He added that the police have been trying to stop the practice, but due to resource constraints, are unable to provide the physical presence of an officer at the locations at all times.According to the Regulations, the Toll Road Operator is responsible to retract the device for the use of the road by emergency service providers, and that it is an offence to interfere with, alter, damage, destroy or remove the device. Dr. Davies also said signs would be put in place at strategic locations to advise motorists of the device.“There is no denying the fact that we are dealing with an unruly bunch that seek to break the law, in order to benefit themselves by not having to go through the toll. Measures have to be taken to ensure that the travelling public is not endangered, so we accept that,” said Member of Parliament for North Central St. Andrew, Karl Samuda.Meanwhile, Dr. Davies said the Ministry went through the process of seeking an opinion from the Attorney General’s Chambers.He noted that the Ministry was advised by the Attorney General’s Chambers that the Road Traffic Act and the Toll Road Act have a legal basis on which spikes may be installed on a slip road.The Regulations will now be sent to the Senate for approval.last_img read more
