"People can access all the information, data and pictures on Facebook through our official website (www.isro.gov.in), as we will be updating the account every three-four hours," Radhakrishnan noted.

Within hours after the rocket was launched from the spaceport at Sriharikota, about 80 km north east of Chennai, the space agency's Facebook account became a terrific hit, getting a whopping 82,000 likes till late Tuesday and 24,145 netizens talking about the mission since the site was launched Oct 22 when the D-day was fixed.

"We want to ensure that people will not forget about the mission days after launch and because the Orbiter will take over nine months to cruise towards Marian orbit by Sep 2014. They can simply access Facebook and know what's happening to the mission in the interplanetary space anytime and from anywhere," the rocket scientist said.
