Chennai, Nov 26: Scientists of the Indian Space Research Organisation (ISRO) commenced the countdown on Friday for the launch of Earth Observation Satellite – Oceansat – and eight other customer satellites on a PSLV-C54 rocket from the spaceport of Sriharikota on Saturday.
The 25.30-hour countdown for the 56th flight of the Polar Satellite Launch Vehicle (PSLV), in its extended version (PSLV-XL), started at 10:26 am today for the lift-off scheduled at 11:56 am on Saturday from the first launchpad at the Satish Dhawan Space Centre, Sriharikota, 115 km from Chennai.
The primary payload of the rocket is an Oceansat which would be separated in orbit-1 while the eight other nano-satellites would be placed in different orbits based on the customer requirements (in the Sun-synchronous polar orbits).
Including the primary payload, nine satellites would ride piggy-back on the 44.4-metre high PSLV-C54 which has a lift-off mass of 321 tonne. It is also the 24th flight of the PSLV-XL version.
The mission would be one of the longest ones undertaken by the ISRO scientists who would engage the rocket to change orbits using two-orbit change thrusters (OCTs) used in the PSLV-C54 launch vehicle. The separation of the Earth Observation Satellite is expected to take place in orbit-1 while the passenger payloads would be separated in Orbit-2.
The Earth Observation Satellite is expected to be placed after reaching an altitude of about 742 km about 20 minutes after lift-off.
After the primary satellite separation, the vehicle would be lowered to reach an altitude of 516 km for placing of the first passenger satellite. The last payload separation is expected to take place at an altitude of 528 km, ISRO said.
The Earth Observation Satellite-6 is the third-generation satellite in the Oceansat series. This is to provide continuity services of Oceansat-2 spacecraft with enhanced payload specifications as well as application areas. The objective of the mission is to ensure data continuity of ocean colour and wind vector data to sustain the operational applications.
The customer payloads include ISRO Nano Satellite-2 for Bhutan (INS-2B) which would have two payloads namely NanoMx and APRS-Digipeater. NanoMx is a multispectral optical imaging payload developed by Space Applications Centre while APRS-Digipeater payload is jointly developed by Department of Information Technology and Telecom, Bhutan, and U R Rao Satellite Centre, Bengaluru.
The ‘Anand’ satellite developed by Pixxel is technology demonstrator to demonstrate the capabilities and commercial applications of miniature earth observation camera for observation using a micro-satellite in low earth orbit.
The ‘Thybolt’ (two satellites) is from another space start-up Dhruva Space while Astrocast is a technology demonstrator satellite for the internet of things as the payload from Spaceflight, the United States of America.

I could never wrap my head around Bollywood’s obsession with continuously addressing condom as a chhatri or an umbrella. Not only it’s cringe to hear repeatedly but also, it somewhere defeats the whole purpose with which films around these subjects are made. Moreover, picking a taboo subject and making a film on it can turn out to be quite risky if you don’t stick to the agenda and beat around the bush. Thankfully, Rakul Preet Singh’s Chhatriwali, directed by Tejas Prabhaa Vijay Deoskar, doesn’t digress much, and follows a crisp screenplay. There are some flaws here and there, but with all the humour and lighter moments, they can be somewhat overlooked.
