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.

New Delhi, Mar 12: TMC MP Saugata Roy said Home Minister Amit Shah should resign for "failing" to control the riots in Delhi and demanded a judicial inquiry by a sitting Supreme Court judge.

Participating in a discussion on the violence in Delhi in Lok Sabha, Roy said the Delhi riots happened 72 years after Mahatma Gandhi was killed by a Hindu fanatic.

"Gandhiji has been murdered again in Delhi by, you know who," Roy said while addressing the Chair.

Taking on BJP MP Meenakshi Lekhi for defending BJP leaders for their controversial remarks, which he claimed instigated the violence, Roy said he has seldom heard such a communal speech ever.

Dubbing the BJP MP as "Devil's Advocate", Roy said, "She spent five minutes defending the most hated man. May I quote (William) Shakespeare and call her the Devil's Advocate?...She is the best Devil's Advocate possible. She has also been an advocate for the Delhi Police which has shown total inaction and ineptness in this whole riot in Delhi."

Thereafter Roy trained his gun at Shah, who was present in the house while the TMC MP was speaking.

He said that when the riots started on February 24, Home Minister Shah was sitting in the front row at Motera Stadium (in Gujarat) welcoming US President Donald Trump.

"When Mr. Shah should have been in Delhi Police control room, he was welcoming Mr. Trump at Motera. There was no order to the police. Then on 25th, things went out of control. Armed mobs fought with each other on the streets of Delhi," Roy said.

Demanding resignation of Shah, Roy raised questions on NSA Ajit Doval's visit to the riots-affected areas on February 26 and asked what was the Home Minister doing.

"Is it NSA's business to control ordinary law and order situation? Why was the Home Minister absent in action? There is no explanation for the same," he said.

The TMC leader said he feels bad standing face-to-face with Shah.

"He is still young, he has a good future. He should acknowledge responsibility for his failure to control or stop Delhi riots and bring peace in three days. In the name of God, go and do not stay in the Home Minister's position," Roy said, adding he is the man who could not prevent riots in Delhi, at a place 10 kilometres away from the Home Ministry.

Roy demanded a judicial inquiry into the riots by a sitting Supreme Court judge and complete rehabilitation for all the riot victims.

New Delhi, Feb 13: Arvind Kejriwal wrote to Delhi Lieutenant Governor Anil Baijal on Wednesday, staking claim to form the government in the national capital, sources said, while hinting that the AAP might not invite senior leaders and chief ministers of other parties for the oath-taking ceremony.

The sources said it was the formal process by the AAP chief, who was elected as the legislature party leader earlier in the day, to stake claim for forming the new government.

Kejriwal, who returned to power in Delhi with a stunning poll victory on Tuesday, will take oath as chief minister for the third consecutive time on February 16.

While the oath-taking ceremony will be open to the public, the Aam Aadmi Party (AAP) was considering not inviting leaders and chief ministers of other parties as it did not wish to be seen as a "confrontationist" against the BJP-led Centre, the sources said.

They, however, added that the party was yet to take a decision on it.

The AAP has planned mobilisation of people for the mega event and all the newly-elected MLAs of the party have been asked to ensure huge participation from their constituencies.

"I request the people of Delhi to attend the oath-taking ceremony of the chief minister at the Ramlila Maidan in large numbers," senior AAP leader Manish Sisodia told reporters, adding that the ceremony will start at 10 am.

The AAP won 62 seats in the 70-member Delhi Assembly, while the Bharatiya Janata Party (BJP) bagged the remaining eight seats. The Congress drew a blank for the second consecutive time in the Delhi polls.
