ISRO successfully launches 42nd PSLV with Cartosat-2

On the occasion of National Youth Day 2018, Prime Minister Narendra Modi applauded the Indian Space Research Organisation (ISRO) for their achievement as they launched the PSLV with 31 satellites successfully.

PSLV C-40 rocket to launch Cartosat, 30 satellites from U.S., other nations in single mission from Sriharikota.

The PSLV-C40 is to place 31 satellites, three Indian and 28 foreign including those of the UK, US, France, Canada, Finland and the Republic of Korea.

The Indian Space Research Organisation (ISRO) had suffered a setback after the failure of the earlier PSLV-C39 mission in August previous year.

Speaking after the success of the PSLV launch, AS Kiran, outgoing Chairman of ISRO said, "During the launch past year, we had problem".

The Indian satellites are 710 kg Cartosat-2 series for earth observation, a 100 kg micro satellite and a 5 kg nano satellite.

That rocket was carrying India's first private sector-built navigation satellite IRNSS-1H, which could not be ultimately put into orbit after the rocket carrying it developed a technical glitch.

The total weight of all the 31 satellites carried onboard is about 1,323 kg (1.45 tons).

Earlier, in a precise launch, PSLV-C40 lifted off at 9.28 am at the end of the 28-hour countdown from the first launch pad of the Satish Dhawan Space Centre here, about 110 km from Chennai, and soared into a cloudy sky.

Heat shield PSLV rocket, a known workhorse, failed to separate after launch.

Today's is the third satellite in the series, after Cartosat-2A and 2B.

After the ejection of the 30th satellite, the fourth stage earth storable liquid engine was restarted for the first time 30 minutes later and was shut off within five seconds.

Soon after the failed mission, there was talk about possible internal sabotage, speculation that an ISRO official brushed away in an interview to a TV channel.
