Post ISRO announces abrupt end of Chandrayaan-I   Posted on: Sat Aug 29, 2009 6:31 pm
ISRO had to abruptly abandon its 10-month maiden moon mission after the spacecraft lost contact with its controllers early on Saturday, much ahead of its two-year mission period.

"The mission is definitely over. We have lost contact with the spacecraft," Mylswamy Annadurai, Project Director of the Chandrayaan-1 told PTI.

However, he said the mission, which had five indigenous and six international experiments, had almost completed its scientific objectives.

"It (Chandrayaan-1) has done its job technically ... 100 per cent. Scientifically also, it has done almost 90-95 per cent of its job," said Annadurai.

The two-year mission, launched on October 22 last year, was abandoned early on Saturday as the mission controllers "abruptly lost" radio contact with the mooncraft at 0130 IST.

The Deep Space Network at Byalalu near here received the data from the 1,380 kg Chandrayaan-1, which carried 11 instruments on board, including six from overseas, during the previous orbit up to 0025 hours, ISRO said in a statement.

Chandrayaan-I, which propelled India into the select group of moon-faring nations, has completed 312 days in space and more than 3400 orbits around the moon.

Earlier, the mission had developed snag in its star sensor which helps focus the spacecraft to a particular lunar position and scientists had to patch up two other instruments to keep its orientation.

Hope that doesn't put a damper on India's enthusiasm.

The Spacecraft has completed 312 days in orbit making more than 3400 orbits around the Moon and providing large volume of data from sophisticated sensors like Terrain Mapping Camera, Hyper-spectral Imager, Moon Mineralogy Mapper etc., meeting most of the scientific objectives of the mission.

Can't be too down, it did pretty good :)
