Iran says it has successfully sent a monkey into space.
The primate travelled in a Pishgam rocket, which reached an altitude of some 120km (75 miles) for a sub-orbital flight before "returning its shipment intact", the defence ministry said.
Iranian state TV showed images of the monkey, which was strapped into a harness, being taken to the rocket.
Western nations have expressed concern that Iran's space programme is being used to develop long-range missiles.
Such missiles could potentially be used to carry nuclear warheads.
Iran denies it is seeking to develop nuclear weapons and insists its nuclear programme is solely for peaceful purposes.
In 2010, Iran successfully sent a rat, turtle and worms into space. But an attempt to send a monkey up in a rocket failed in 2011.
President Mahmoud Ahmadinejad announced in 2010 that the country planned to send a man into space by 2019.
A domestically-made satellite was sent into orbit for the first time in 2009.

spiral galaxy NGC 6872


NASA

04:04 (edited)  -  Public
This composite of the giant barred spiral galaxy NGC 6872 combines visible light images from the European Southern Observatory's Very Large Telescope with far-ultraviolet (1,528 angstroms) data from NASA's GALEX and 3.6-micron infrared data acquired by NASA's Spitzer Space Telescope. A previously unsuspected tidal dwarf galaxy candidate appears only in the ultraviolet, indicating the presence of many hot young stars. IC 4970, the small disk galaxy interacting with NGC 6872, is located above the spiral's central region. The spiral is 522,000 light-years across from the tip of one outstretched arm to the tip of the other, which makes it about 5 times the size of our home galaxy, the Milky Way. Images of lower resolution from the Digital Sky Survey were used to fill in marginal areas not covered by the other data. Credit: NASA's Goddard Space Flight Center/ESO/JPL-Caltech/DSS

Wind power deadline sees US firms rush to build turbines


Wind power deadline sees US firms rush to build turbines

wind turbines california2012 has seen large numbers of wind turbines installed all across the US.

US energy companies are racing to install wind turbines before a federal tax credit expires at the end of this year.
Experts say that wind power has exceeded the construction of natural gas plants in recent months.
However the financial incentive for wind could be lost as congress struggles to avoid financial deadlock.
Even if the credit is extended it is expected that new installations will decline in 2013.
According to industry analysts, the federal government's production tax credit has played an important role in the expansion of wind energy across the US since it was first introduced in 1992.
Wind passes gas
At that point there was less than 1.5 gigawatts of power generating capacity provided by wind across the country. That figure has grown dramatically. This year has seen around 12 gigawatts of wind power capacity installed, outpacing even natural gas projects which have boomed on the back of cheap shale.

Rob GramlichAmerican Wind Energy Association
The government subsidy works out at 2.2 cents per kilowatt hour of power produced over ten years. This amounts to around $1m (£620,000) for every large turbine. However the deadline is absolute - to get the money the blades on new installations must be turning and generating power before the 31st of December.
"There's a lot of rushing right now to get projects completed by the end of the year," says Rob Gramlich, senior vice president at the American Wind Energy Association.
"It is not a great way to run a business with this policy-induced uncertainty."
The tax credit has proved contentious with some lawmakers criticising it as too generous. It lapsed previously in 1999, 2001 and 2003. Each time it lead to a collapse in new construction.
The American Wind Energy Association are hoping the tax credit will be passed as part of a compromise package of legislation to help the US avoid the so-called fiscal cliff. The say the most likely outcome is a short term extension of the subsidy.
TurbinesThe federal financial subsidy is around 30 % of the cost of a large turbine.
"There's a good chance we could get this extension, it is very hard to predict, but the industry is not making bets on the Congress getting it done," says Mr Gramlich,
Even if there is an extension there is likely to be a significant curtailment of wind installations in 2013. Wind energy companies say they need longer time frames to negotiate deals to sell the power they generate.
Iberdrola Renewables is the second largest developer of wind power projects in the United States. The company is racing to finalise new wind installations in Massachusetts and New Hampshire.
However the prospects for new turbines in 2013 are slim according to Paul Copleman, communications manager for Iberdrola.
"Even if the tax credit is extended, our new construction plans likely will be ramped back substantially in 2013 compared with the last few years. So much time has passed without certainty that a normal one-year extension would not be a game-changer for our 2013 build plans."
Some analysts argue that all subsidies to wind should end and the industry should stand on its own two feet. They say that the current arrangements mean that energy companies continue to make money even when there is a surplus of wind and the market price is negative.
Dan Kish is with the Institute for Energy Research, a body long critical of subsidies for renewables. He told BBC News the extension of the tax credit was expensive, unnecessary and destabilising to the electricity grid.
"Wind produces power at a fraction of its stated capacity, and is increasingly adding unnecessary costs to consumers, just as it is in the UK," he said
"They are creations of government and serve only to make their builders and owners wealthy at the expense of the public."

e-waste

Britain's e-waste illegally leaking into West Africa
boy on Ghana dumpsite

In Britain each year, we throw away a million tonnes of electronic waste - enough to fill Wembley Stadium six times over. So what happens to our broken TVs and computers - our e-waste - once we have dumped it? Raphael Rowe reports from Ghana.
When he turns his hand over, 10-year-old Mohammed reveals the deep open cut on his thumb, visible through the black soot that covers his small hands. Two other cuts have been covered up with blackened, filthy plasters.
He tells me that the wounds are from the sharp copper wire that he is scavenging from the biggest digital graveyard in Africa.
The Agbogbloshie dumpsite is where the poorest of nearby Accra stream in order to scrape out a living from the tons of electrical waste piled here.

Alfred, 12, said he has no choice but to eke out a living at the dumpsite since his mother died. He complained of headaches from the toxic fumes as he and the others use their hands, hammers and fire to extract precious metals from the scrap heap.
Activists told me the nearby river is dead owing to the contamination from this crude form of recycling.
And, they add, much of this electronic garbage - known as e-waste - originates in the UK.
Mike Anane is a campaigner with the League of Environmental Journalists which is trying to stop e-waste pouring into Ghana.
"We are destroying the lives of children, we are destroying the environment, the rivers no longer have fish, just because of the illegal shipments and dumping of electronic waste from the UK," he said.
Tracking devices
It is estimated that 100,000 tons of e-waste is leaking out of the UK each year via the ports that see seven million containers exported each year.
 There needs to be a lot more enforcement, but there also needs to be a shake-up of how we handle electronic waste in the UK 
Environmental Investigation Agency campaign group
A confidential report obtained by Panorama suggests that 77% of e-waste from England and Wales ends up in West Africa, primarily Ghana and Nigeria.
Environmental law states that broken electronics, everything from fridges to televisions to computer monitors, should be responsibly recycled within the UK. Discarded electronics need to be tested to ensure they work before they can be legally exported for resale, usually to the developing world.
But a BBC Panorama investigation that involved putting hidden tracking devices in broken televisions found evidence of large amounts of e-waste being illegally shipped to West Africa where boys like Mohammed and Alfred are risking their health for scraps of copper and pennies a day.
The Environment Agency, which has a special investigations unit dedicated to halting these illegal exports, said the reason behind the trade is obvious.
"There is a vast sum of money to be made by exporting abroad illegally," said Chris Smith, National Intelligence Manager at the EA.
The government estimates that a 40-foot container of used televisions can contain as many as 600 sets and is worth £7,000 in the street markets of West Africa.
It estimates that one in eight containers claiming to be working electronics, is in fact broken e-waste.
The maximum penalty for the illegal export of e-waste is an unlimited fine and two years in prison. But in practice the maximum fine has been around £12,000 and no one has been sent to prison.
'Send a message'
Margaret Bates, a lecturer in sustainable waste management at Northampton University, said that while other streams of waste are being reduced owing to recycling efforts, e-waste is going in the opposite direction - growing at a rate of 5% a year.

She said the cost and time it takes to safely recycle e-waste is fuelling the illegal trade.
Ms Bates said it is time for a message to be sent to illegal exporters.
"Until fairly recently a lot of the criminals involved in the e-waste trade didn't think they were going to get caught. We need to see people who are doing this sort of thing coming through regularly in the courts and being made to suffer for it."
Posing as a small business, Panorama placed a hidden tracking device in a broken television set and then paid a private recycling firm, Sanak Ventures, to dispose of the set.
From the company's warehouse in Wembley, the tracker showed that the television was soon on the move to Felixstowe Docks, then shipped to Ghana before if finally ended up in Lagos, Nigeria.
And it was in Lagos, in a street market, that we found it - still broken - and for sale for £40.
Taking responsibility
When asked about how a broken television managed to be exported, Sanak Ventures said they were a respectable company and denied any wrong-doing, but they failed to answer our question of how our broken JVC television ended up in Nigeria.

Campaigner Mike Anane says the onus is on the UK to halt e-waste
Activist Mike Anane said while governments in Africa are attempting to legislate against the e-waste trade, the source of the broken electronics needs to be addressed.
"I think that the onus and greater part of the responsibility rest with the people in the UK," he said.
It is a sentiment echoed by the Environmental Investigation Agency - a campaign group.
A spokeswoman for the group, which has also attempted to track e-waste from the UK to West Africa, said: "There needs to be a lot more enforcement, but there also needs to be a shake-up of how we handle electronic waste in the UK and our waste needs to be much more closely monitored than it ever has been."

SpaceX capsule returns with safe landing in Pacific


SpaceX capsule returns with safe landing in Pacific

The capsule returned to Earth carrying an unusual cargo

Related Stories

A space capsule has returned to Earth, ending the first commercially contracted re-supply mission to the International Space Station (ISS).
The capsule was sent by the California-based company SpaceX, the first of 12 missions it will perform for US space agency Nasa.
It landed in the Pacific Ocean west of Mexico at 12:22 local time (19:22 GMT).
Nasa is looking to the private sector to assume routine transport duties to and from low-Earth orbit.
The robotic Dragon ship lifted off on 7 October, with 400kg of food, clothing, experiments and spares for the orbiting platform's six astronauts, and docked three days later.
On its return, the capsule carried broken machinery and medical samples gathered by the astronauts aboard the ISS over the course of the past year.
SpaceX's next mission is expected in January, although the company will need to satisfy Nasa before then that the cause of an engine anomaly experienced by Dragon's launch rocket during its 7 October ascent has been understood, and that corrective action has been taken.

International Space Station

International Space Station
  • The International Space Station (ISS) is larger than a football pitch
  • The first module called Zarya was launched into orbit in 1998
  • It took 13 years to complete at a cost of around $100bn
  • There is a permanent crew of six astronauts onboard who carry out space environment research
New destinations
Nasa has given SpaceX a $1.6bn contract to keep the ISS stocked with essentials, restoring a re-supply capability that the US lost when it retired its shuttles last year.
The terms of the contract kicked in following a successful test of Dragon's systems in May.
That demonstration saw the capsule berth with the ISS - the first commercially designed and built vehicle to do so - and then return safely to Earth.
Nasa hopes a second company can also soon begin operational cargo deliveries to the station.
The Orbital Sciences Corporation (OSC) will shortly test its new Antares rocket before undertaking its own ISS demonstration with a robotic vessel called Cygnus.
If that mission - tipped to take place next year - goes well, it will trigger a $1.9bn contract for Orbital.
Nasa's aim is eventually to put astronaut transport in the hands of the private sector too.
SpaceX says it is just a few years away from being able to provide an astronaut "taxi" service.
Nasa's policy of outsourcing its cargo and crew transport needs is intended to find savings that can be ploughed back into building a rocket and capsule system capable of taking humans to more challenging destinations.
