Mars Orbiter Spacecraft Successfully placed in Mars Transfer Trajectory
The critical manoeuvre to place India's Mars Orbiter Spacecraft in the Mars Transfer Trajectory was successfully carried out in the early hours of today (Sunday, December 1, 2013). During this manoeuvre, which began at 00:49 today, the spacecraft's 440 Newton liquid engine was fired for about 22 minutes providing a velocity increment of 648 meters/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.

It may be recalled that Mars Orbiter spacecraft was launched into an elliptical parking orbit with a perigee (nearest point to Earth) of 248 km and an apogee (farthest point to Earth) of 23,550 km by India's workhorse launch vehicle PSLV on November 5, 2013. Following this, the apogee height of the spacecraft's orbit was successively raised through a series of manoeuvres to nearly 1,93,000 km. Besides, health checks of the Mars Orbiter spacecraft as well as its payloads were performed. Since its launch, all systems on-board Mars Orbiter spacecraft are performing normally.

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.

This is phenomenal!!!

Can someone cite the source as well?

Mangalyaan successfully cruising towards Mars as it leaves Earth's orbit

Mangalyaan being launched from Sriharikota

New Delhi: India's maiden spacecraft to Mars has successfully left the Earth's orbit and is now cruising towards Mars after a crucial and tricky midnight operation. The complex operation began as planned at 49 minutes after midnight and lasted 23 minutes in which the spacecraft was given a nudge so that it escapes the Earth's gravity.
Indian Space Research Organisation or ISRO says the operation went off successfully and the Mangalyaan has left the Earth's embrace and is now on course on the highway to Mars.

"The trans-Mars injection has been completed successfully," K Radhakrishnan, Chairman of ISRO, told NDTV.

Launched on November 5, 2013 from Sriharikota, the Mangalyaan had till now been rotating around the Earth. It was given that final extra kick through a sling shot mechanism as it began its over 750 million kilometer journey to Mars. Each day, the Mangalyaan will cover over 2.5 million km hurtling into space till it is slowed down to be captured by Mars.

About 250 scientists from ISRO monitored its health. The command for the spacecraft to leave the Earth's orbit and head into the Sun-centric orbit was executed from the Mission Operations Center in Bangalore.

The success of the mission can be assessed only when the spacecraft reaches the Martian orbit on September 24, 2014. Once it reaches Mars, the Mangalyaan will revolve around the 'Red Planet' for six months and announce India's triumph.

However, the risks are many and no country till date has succeeded in reaching Mars on its maiden attempt. More than half of all missions to Mars have ended in failure, including China's in 2011 and Japan's in 1998.

The Rs 450-crore mission to Mars has made international headlines, at least in part for its cost-efficiency.

  • In the fourth orbit-raising operation conducted this morning (Nov 11, 2013), the apogee (farthest point to Earth) of Mars Orbiter Spacecraft was raised from 71,623 km to 78,276 km by imparting an incremental velocity of 35 metres/second (as against 130 metres/second originally planned to raise apogee to about 100,000 [1 lakh] km). The spacecraft is in normal health. More..

  • PSLV-C25, in its twenty fifth flight, successfully launches Mars Orbiter Mission Spacecraft from SDSC SHAR Sriharikota

congrats !:victory:

so the most difficult phase is over ?:what:
The most difficult stage would be Mars orbit insertion maneuver. The MOM has to fire its braking rockets to be captured into Mars orbit and the rocket will have to be restarted after bring dormant for almost 300days in cold space.
 
.
Just superb!! now fingers crosses on the rest of the journey to Mars think its sometime in Sept when it will arrive in Mars orbit.
