Indian-American astronaut Sunita Williams takes off for second space journey

    Indian-American astronaut Sunita Williams takes off for second space journey       

        BAIKONUR, KAZAKHSTAN: A Russian Soyuz craft launched into the morning skies over Kazakhstan on Sunday, carrying three astronauts on their way to the international space station, where they will quickly start preparing for a frenzy of incoming traffic.

      NASA astronaut Sunita Williams, Russian cosmonaut Yury Malenchenko and Japan's Akihito Hoshide are set to travel two days before reaching their three colleagues already at the permanent space outpost.

        Families and colleagues watched the launch from an observation platform in the Russian-leased cosmodrome in the dry southern steppes of this sprawling Central Asian nation.

        Liftoff took place at the exact scheduled time of 8.40am local time (0240 GMT), sending a deafening roar as the craft gained height.

       Despite withstanding intense G-force pressure, the three astronauts looked relaxed in televised footage as they performed a series of routine operations.

      The Soyuz jettisoned three rocket booster stages as it was propelled into orbit, which takes just over nine minutes.

      At that stage, a doll given to Malenchenko as a mascot by his daughter and suspended over the three astronauts floated out of view on television footage, indicating the craft had escaped the earth's gravitational pull.

      The shell that surrounds the capsule during the launch phase also peeled away, soaking the astronauts in bright yellow sunshine pouring through the viewing hatches.

     The solar arrays that deployed on the Soyuz after orbital entry will provide the craft with the power it needs during its two-day trip.

     Williams, tightly squeezed into the cramped craft, gave a thumbs-up sign and waved to onboard cameras as Russian space agency chief Vladimir Popovkin congratulated the crew over radio control.

      Malenchenko, who is piloting the Soyuz, is one of Russia's most experienced astronauts and is making his fifth voyage into space.

       Williams, who was born in Euclid, Ohio, and raised in Massachusetts, is on her second mission and will further extend the record for the longest sojourn in space for a female astronaut. The 46-year old astronaut, who is of Indian-American heritage, spent 195 days at the space station in 2006-2007.

        Sunday's launch took place on the 37th anniversary of the landmark Apollo-Soyuz mission during which crafts from the United States and the Soviet Union docked in space, setting a precedent for scientific cooperation between the Cold War foes.

    Williams said in a press conference ahead of the launch that the test mission laid the ground for a long-standing friendship and collaboration in the space program.

     The Soyuz is schedule to dock Tuesday with the space station at 8.52am Moscow time (0452 GMT).

      Russians Gennady Padalka and Sergei Revin and US astronaut Joseph Acaba, who make up the crew of Expedition 32, have been working at the space station since mid-May.

      The space station, which orbits up to 410 kilometers (255 miles) above the earth, is braced to handle an unprecedented level of traffic.

       Japan's HTV3 cargo ship will dock with the space station next week and will be the first of nine craft making contact with the orbiting satellite over a 17-day span.

      Expeditions 32 and the incoming Expedition 33 have 33 experiments planned for their stay at the orbiting laboratory.                                                                          







Government nod for Mars mission soon

Government nod for Mars mission soon

     MYSORE: Isro chairman K Radhakrishnan on Saturday said the government's nod to the country's Mars mission is expected soon.



      "India's much-awaited mission to Mars is in the final stage of approval," said Radhakrishnan. The mission will be launched from Sriharikota in Andhra either in November 2013, 2016 or 2018.

       "Many studies have been done relating to this mission,'' said Radhakrishnan.

       A scientist on condition of anonymity said global interest and excitement following NASA's Mars Science Laboratory (MSL) landing on Mars on August 6 could prompt the Indian government to clear the programme. "We're waiting to go to Mars," said a scientist.

     Initially, nine scientific experiments were designed for this flight. This could be reduced considering the weight factor. The rocket will be an advanced version of the highly-proven four-stage Polar Satellite Launch Vehicle, designated as PSLV-XL, used for India's mission to moon, Chandrayaan-1.

    Radhakrishnan said India's first dedicated astronomy satellite, Astrosat, will be launched in 2013. "All the instruments are going through their final evaluation and it'll be a national laboratory available to scientists both in India and abroad," he said. The mission was delayed for various reasons. About the Geo Synchronous Satellite Launch Vehicle Mark 2, he said the flight stage of the cryogenic engine should be ready in November 2012.

Cash receipts, currency notes carry toxic hazards: Study


WASHINGTON: Some currency notes and cash receipts, printed on thermal paper, carry higher levels of bisphenol-S (BPS), a substitute for bisphenol-A or BPA, both of which are toxic health hazards, says a new study.

BPS is closely related to BPA, with some of the same estrogen-mimicking effects, and unanswered questions exist about whether it is safer.

Estrogen is a hormone that controls brain development, the reproductive system and foetus development.

Animal studies have shown that BPA can cause genetic damage, besides causing cancer, diabetes and obesity.

Very little is known about BPS occurrence in the environment, said Kurunthachalam Kannan, professor of organic analytical chemistry at the School of Public Health, Environmental Health Sciences, US, who led the study, the journal Environmental Science & Technology reports.

Accordingly, in the first ever analysis of 16 types of paper from the US, Japan, Korea and Vietnam, they detected BPS in all the receipt paper they tested, 87 percent of the samples of paper currency and 52 percent of recycled paper.

Researchers estimate that people may be absorbing BPS through their skin in larger doses than they absorbed BPA when it was more widely used - 19 times more BPS than BPA. People who handle thermal paper in their jobs may be absorbing much more BPS, according to a School of Public Health statement.

Kannan, also researcher at Wadsworth Centre of New York State Department of Health, and colleagues point out that growing evidence of the potentially toxic effects of BPA has led some manufacturers to replace it with BPS in thermal paper and other products.

Only 60% of Sarva Shiksha Abhiyan funds used IN GUJARAT, BUT TAMILNADU UTILIZE ALL FUNDS FROM THE CENTRAL GOVT SSA


AHMEDABAD: The central government allocated Rs 1,360.35 crore for the Sarva Shiksha Abhiyan, but Gujarat has only spent Rs 790 crore. The spending was less than 60 per cent of the allocation.
Manish Doshi, spokesperson of Gujarat Pradesh Congress Committee said that in the last 10 years, the union government has allotted Rs 1,360.36 crore, out of which the state government has spent just Rs 461.66 crore for the Sarva Shiksha Abhiyan in 26 districts and another Rs 325.55 crore in Ahmedabad, Surat, Rajkot and Vadodara.
He alleged that the major part of the central funds had been used for civil work, which included repairs of school buildings.
Doshi said that the under-utilization of funds speaks of the education policy of the state government. He said the government is not worried about children from low income groups.
He said that the government, by not utilizing the funds properly, has thus taken away the Right to Education from poor students.
Doshi added that according to the annual report published, the government has allocated only 28 per cent of the funds for Vadodara, 21 per cent for Surat, 35 per cent for Rajkot and only 69 per cent for Ahmedabad city.
"It is crystal clear that this BJP government is not bothered about the future of poor children in cities," alleged the GPCC spokesperson.
