MANGALYAAN 1st STAGE SUCCESS

In a major milestone in India's space history, ISRO's Mars Orbiter mission today ventured out of Earth's sphere of influence, beginning its 300-day journey to the Red planet. The critical manoeuvre to place the Mars Orbiter Spacecraft or 'Mangalyaan' in the Mars Transfer Trajectory was successfully carried out almost an hour past midnight and marked the first step it its 680 million-kilometre-long voyage to its destination. "Following the completion of this manoeuvre, the Earth orbiting phase of the spacecraft ended. The spacecraft is now on a course to encounter Mars after a journey of about 10 months around the Sun," the Bangalore-headquartered Indian Space Research Organisation said in a statement. During this manoeuvre, which began at 00:49 hours, the spacecraft's 440 Newton liquid engine was fired for about 22 minutes providing a velocity increment of 648 metres/second to the spacecraft. ISRO performed the trans-Mars injection, a "crucial event" intended for hurling its Mars Orbiter spacecraft into the planned orbit around the Sun. It has planned four mid-course corrections in case of any deviation along its path to the Martian orbit before its expected arrival in the orbit of the Red planet in September 2014. It had performed five orbit-raising manoeuvres on its Mars Orbiter, raising the apogee (farthest point from Earth) of the spacecraft to over 1.92 lakh kilometres, before it performed the "mother of all slingshots." The spacecraft is being continuously monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennae at Byalalu here, the space agency added. ISRO's PSLV C 25 successfully injected the 1,350-kg 'Mangalyaan' Orbiter (Mars craft) into the orbit around the earth some 44 minutes after a text book launch at 2.38 PM from the Satish Dhawan Space Centre at Sriharikota on November 5, marking the successful completion of the first stage of the Rs 450-crore mission.

AIYAR GOT MAD

Congress leader Manishankar Aiyar attracted opposition BJP's ire today in Rajya Sabha when he said he was not interested in listening to speech of a BJP member on vote on account, prompting the Chair to adjourn the House amid uproar. During the Zero Hour, Deputy Chairman P J Kurien allowed Aiyar, who wanted to ask a question, to do so, which was opposed by BJP members. Kurien asked Aiyar whether he yielded to allow others to speak, to which he said he had no objection and he can ask his question later. As the House got ready to initiate discussion on Vote on Account, Kurien said, "Let us reduce the discussion to two hours from four hours," which was opposed by BJP members including Piyush Goyal who was given a chance to speak on Vote on Account. When it was agreed that discussion will take place as per schedule, Aiyar remarked he was not interested in listening to the speech by BJP member. "You had given me the chance to ask a question

"Today, till 4.30 pm, metro has crossed the one million mark of ridership that it achieved within 59 hours of operation since inception of commercial operation," a release from Mumbai Metro One, an arm of Reliance Infrastructure, said. This is the only Metro in the country that carries an average of 1,487 commuters per km per hour, it added. "Precisely, it carries almost double the number of commuters every day as compared to Delhi Metro. This proves the overwhelming acceptance of Mumbai Metro by the people." The company has offered a promotional fare of Rs 10 for the first 30 days irrespective of the distance travelled.
