Yes…!! India Has Done It. History is Created…!! Mars Mission Successful, ISRO Confirms

India on Wednesday made history by becoming the first country in the world to enter the Martian orbit in its maiden attempt. The Indian Space Research Organisation (ISRO) successfully inserted the Mars Orbiter into the red planet’s orbit.

“The spacecraft (Orbiter) was successfully inserted into the Martian orbit at 515 km away from the red planet’s surface and 215 million km away from the earth in radio distance,” a senior space official said.

The Mars orbit insertion began in the early hours at 4:17 am when the spacecraft switched over to the medium gain antenna for emitting and receiving radio signals.

After rotating the Orbiter in the direction of Mars at 6:57 am, the main engine was ignited at 7:17 am to enable the spacecraft enter the Martian orbit.

During the crucial operation, when an eclipse occurred on Mars from 7:12 am, the 440 Newton liquid apogee motor (LAM) of the main engine started burning at 7:30 am and lasted for 24 minutes till 7:54 am for inserting the spacecraft into the Martian orbit.

“Radars at the four earth stations across the US, Europe, India and Australia received the signal confirming the successful insertion of the spacecraft into the Martian orbit,” the official said.

The spacecraft consumed about 250 kg of liquid fuel with oxidiser.

Scientits at the country’s premier space research organisation had test-fired the liquid rocket motor on the Mars Orbiter, which was in slumber since the 300-day journey began, for four seconds on Monday.

marThe orbiter on Monday entered within 580,000km from Mars in a hyperbolic trajectory after which the fourth trajectory correction manoeuvre took place and then the main liquid engine was test-fired for 3.968 seconds.

The deep space networks of America’s National Aeronautics and Space Administration (NASA) at California in the US, Madrid in Spain and Canberra in Australia coordinated with ISRO’s deep space network at Baylalu, about 40 km from Bangalore, for receiving the signals from the spacecraft after its insertion into the Martian orbit.

The five scientific instruments on board the 475-kg Orbiter will study the Martian surface and its mineral composition and scan its atmosphere for methane gas.
