Isro to launch rocket carrying 6 Singapore satellites today

India is all set to launch PSLV-C-29 rocket carrying six Singapore satellites on Wednesday from the country’s space port of Sriharikota.

Indian Space Research Organisation (Isro) on Tuesday said the 59-hour countdown, which started on Monday, is progressing smoothly.

A senior official from Isro told Deccan Herald that propellant and mixed oxides of nitrogen filling operation of the fourth stage has been completed.

Isro’s most-trusted rocket and workhorse launch vehicle PSLV-C29, in its thirty-second flight, will carry these six satellite to be thrust into 550-km circular orbit after its takeoff at 6 pm from the launch pad in Satish Dhawan Space Centre.

According to the Isro officials, of these six satellites, TeLEOS-1 is the primary satellite weighing 400 kg, whereas the other five are co-passenter satellites, which include two micro-satellites and three nano-satellites.

This is the eleventh flight of PSLV in “core-alone” configuration that will not use the solid strap-on motors. The official said the TeLEOS-1 is the first Singapore commercial earth observation satellite designed and developed by ST Electronics. This electro-optical satellite is to be launched into a low earth orbit for remote-sensing applications.

In 2015, Isro has launched 14 satellites (3 Indian and 11 foreign) from its rocket port in Sriharikota till date. Thirteen satellites were launched with PSLV rocket and one communication satellite–GSAT-6-with geosynchronous satellite launch vehicle (GSLV).

The December 16 PSLV-C-29 launch will take the total number satellite launches from India to 20. Last month, India also launched its communication satellite GSAT-15 using the Ariane rocket of the European space agency which takes the total number of satellite launches in 2015 to 21 (17 foreign, 4 Indian).
