Chennai/Bangalore, Dec 1: Crossing a major milestone in the country's space history, ISRO's Mars Orbiter mission today ventured out of Earth's sphere of influence for the first time in an attempt to reach the red planet's orbit.

The critical manoeuvre to place the Mars Orbiter Spacecraft in the Mars Transfer Trajectory was successfully carried out almost an hour past midnight.

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.

"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 Organization said in a statement.

ISRO performed the trans-Mars injection, a "crucial event" intended for hurling its Mars Orbiter spacecraft into the planned orbit around the Sun, marking the first step towards the 300 day voyage to reach the orbit of the red planet after crossing roughly 680 million kilometer.

"The Trans Mars Injection (TMI) operations, which began at 00.49 hours (IST) completed," ISRO said.

ISRO has planned four mid-course corrections in case of any deviation along its path to the Martian orbit.

The space agency is scheduled to make four corrections in the course of the spacecraft's voyage to Mars before it is expected to reach 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 kilometers, 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.

Jun 8: Petrol and diesel prices were hiked by 60 paisa per litre on Monday, for the second day in a row, as state-owned oil firms reverted to daily price revisions after a 83-day hiatus.

Petrol price in Delhi was hiked to Rs 72.46 per litre from Rs 71.86 on Sunday, while diesel rates were increased to Rs 70.59 a litre from Rs 69.99, according to a price notification of state oil marketing companies.

This is the second daily increase in rates in a row. Oil companies had on Sunday raised prices by 60 paisa per litre on both petrol and diesel after ending a 83-day hiatus in daily rate revision.

Daily price revision has restarted, an oil company official said.

While oil PSUs have regularly revised ATF and LPG prices, they had since March 16 kept petrol and diesel prices on hold, ostensibly on account of extreme volatility in the international oil markets.

Auto fuel prices were frozen soon after the government raised excise duty on petrol and diesel by Rs 3 per litre each to mop up gains arising from falling international rates.

The government on May 6 again raised excise duties by Rs 10 per litre on petrol and Rs 13 per litre on diesel.

Oil companies, instead of passing on the excise hike to consumers, decided to adjust them against the reduction required because of the drop in international oil prices. They used the same tool and did not pass on the Re 1 per litre hike required for switching over to ultra-clean BS-VI grade fuel from April 1.
