Countdown begins for ISRO's heaviest commercial mission


The 62.5-hour countdown began today at 07.28 AM and is progressing smoothly, an ISRO official told. ISRO's workhorse Polar Satellite Launch Vehicle (PSLV) will blast off at 9.58 PM on July 10 from the Satish Dhawan Space Centre at Sriharikota, about 90 km from here, and put in orbit the five satellites.

With the overall lift-off mass of the five satellites amounting to about 1440 kg, this mission becomes the 'heaviest commercial mission' ever undertaken by ISRO and its commercial arm Antrix, the agency said.

The Mission Readiness Review Committee and Launch Authorisation Board cleared the countdown for the PSLV C28/ DMC3 mission yesterday, he said.

PSLV, in its 30th mission, will launch three identical DMC3 optical earth observation satellites, built by Surrey Satellite Technology Limited (SSTL), United Kingdom, and two auxiliary satellites.

The three DMC3 satellites, each weighing 447 kg, will be launched into a 647 km Sun-Synchronous Orbit (SSO) using the high-end version of PSLV-XL.

In addition to the three DMC3 satellites, the PSLV C28 will also carry two auxiliary satellites from UK -- CBNT-1, a technology demonstrator earth observation micro satellite built by SSTL, and De-OrbitSail, a technology demonstrator nano satellite built by Surrey Space Centre.

The five international satellites are being launched as part of the arrangement entered into between DMC International Imaging (DMCii), a wholly owned subsidiary of SSTL, UK and Antrix Corporation Limited.

India may launch two more navigation satellites this year

Indian Space Research Organisation (ISRO) officials deny any diversion of focus is delaying the operationalisation of navigation satellite system.

The three satellite launches will be in addition to the one that India is expected to put into orbit on March 28 evening.

"We will surely be launching two more navigation satellites this year apart from tomorrow's (March 28) launch. At the end of the year we will have six navigation satellites up in the sky out of the constellation of seven such satellites," senior officials of Indian Space Research Organisation (ISRO) said.

According to officials, the seventh and the last one of the Indian Regional Navigation Satellite System (IRNSS) in all probability would go up early part of 2016.

The full navigation services are expected to be offered from mid 2016 onwards, according to the officials.

They said the countdown for Saturday's rocket launch is progressing at a good pace in a smooth manner and all the activities are geared up for the 5.19 PM blast off of the rocket.
