Ecliptic makes an angle of 23 deg with equator so effectively the orbit is about 23+19=42 deg w.r.t. ecliptic which approx corresponds to the 150 deg inclination of the probe at Mars. So the s/c has to travel in that plane which is oblique to ecliptic when released from Earth's gravitational force.

India is the first Asian country and fourth nation in the world to leap into the interplanetary space, thanks to today's development.

CHENNAI: Isro's Mars Orbiter Mission, which was placed in inter-Mars trajectory in the early hours on Sunday, has crossed Moon's orbit and is travelling beyond Earth's natural satellite.

"The Mars Orbiter spacecraft has crossed the Moon orbit. So technically after crossing our Chandrayaan's orbit, it is now travelling beyond the Moon. It is crossing around 10,00,000 km per day," Isro sources said.

This is the first time an Indian-made object is being sent into deep space, they said.

Isro's Mars Orbiter Mission had ventured out of Earth's sphere of influence on Sunday, beginning its 300-day journey to the Red planet, marking a major milestone in India's space history.

Isro performed the trans-Mars injection, a "crucial event" intended to hurl its Mars Orbiter spacecraft into the planned orbit around the sun at around 00.49 hours on Sunday.

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 km 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.

Isro's PSLV C 25 injected the 1,350-kg 'Mangalyaan' orbiter into the orbit around Earth about 44 minutes after launch at 2.38pm from Satish Dhawan Space Centre at Sriharikota on November 5, marking the successful completion of the first stage of the Rs 450 crore mission.

Thanks Lilo, I was worried for a min

Also we cdo not know if they actually ahve some cameras for mission critical monitoring which they may not release publicly.
