Indians throng FB, Twitter, hail ISRO

New Delhi: Indians were elated for becoming the first country in the world to enter the Martian orbit in its maiden attempt on Wednesday, and many took to Facebook and Twitter saying ‘mission accomplished’.

Happy and proud Indians, including many living abroad, took to the social networking sites to express their happiness and share the moment of pride.

#Mangalyaan #MissionMars #proudindian were some of the top trending topics on Twitter and Facebook. Praising the scientists of the state-run Indian Space Research Organisation (ISRO), Sonal Kalra wrote on her Facebook wall, “Nothing compares to the proud feeling of seeing the genuine smiles on the faces of Indian scientists.” “Congratulations to all the scientists and engineers of ISRO on successfully inserting the Orbiter into Martian orbit, that too in the first attempt!” wrote Ravi Prakash on his wall. Gauraw Patil was more impressed by the cost-effectiveness of the project. “Mission accomplished. After world’s cheapest $2,500 car, $30 tablet, now comes mission to Mars at just $74 mn. ISRO has achieved truly a remarkable feat that no one ever dreamed could be possible,” he tweeted.

Nail biting moments gave way to celebratory mood at the command centre of ISRO centre, as the historic arrival of Mangalyaal in the Martian orbit was announced. The Free Press Journal tracked the five stage launch of the Mars orbiter.

Below is the highlight of the Mangalyaan’s journey so far:

l 1st & 2nd orbit raising maneuvers The first orbit raising activity for the Mars Orbiter was successfully completed on 7th November 2013.  The second manouevre was completed on 8th November 2013. According to ISRO, the second orbit raising maneuver started at 2.18 a.m. The on-board motor of Mars Orbiter was fired for 570.6 seconds taking up the Mars Orbiter to 40,186 km apogee (farthest point to the Earth) from the earlier levels of 28,814 km.

l 3rd & 4th orbit raising maneuvers

The third maneuvers was performed on early Wednesday morning, raising its apogee, the farthest point from Earth, to over 71,000 km. The maneuver started at 2:10 am and raised the spacecraft’s apogee from 40,186 km to 71,636 km with a burn time of 707 seconds.

In the fourth orbit raising operation today, the apogee was raised to 78,276 km against the target of about one lakh km, because incremental velocity imparted to the spacecraft was 35 m/s against the targeted 130 m/s.

l 5th & the last orbit raising maneuvers

 was conducted on 16th November 2013 and was successful. On 10th April 2014, the Orbitor had crossed its halfway mark and the spacecraft and its five scientific instruments were in good health. On Wednesday when the Orbitor  faced its first test scientist were skeptical whether the engines would start as it was idle for 300 days. But their worries were put to rest.

— 24th September 2014 history created.
