ISRO successfully launched its own earth observation satellite Resourcesat-2A on 7 December 2016. The observation satellite Resourcesat -2A was launched with PSLV C36/ RESOURCESAT-2A from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
The PSLV-XL variant rocket standing 44.4 meters tall and weighing 321 tonne tore into the morning skies at 10.25am with a reverberating sound breaking free of the earth’s gravitational pull. The Resourcesat-2A weighing 1235 kilograms was injected into an 817 km polar Sun Synchronous Orbit (SSO) at around 20 minutes into the destination.
Resourcesat-2A is a remote sensing satellite and is intending for resource monitoring. It is a follow-on mission to Resourcesat-1 and Resourcesat-2, which were launched in 2003 and 2011 respectively. This satellite is intended to continue the remote sensing data services to global users provided by its two predecessors. The Resourcesat-2A carries three payloads which are similar to those of the earlier two Resourcesat’s. This mission will provide inputs in avionic science.
It carries two solid state recorders with a capacity of 200 Giga Bits each to store the images taken by its cameras. These images can be read out later to ground stations. The data sent by Resource would be analysed at Hyderabad from 15 December 2016.
PSLV-C36 is the 38th flight of ISRO’s Polar Satellite Launch Vehicle (PSLV). This flight used the 'XL' version of PSLV with six solid strap-on motors.

The PSLV rockets are a four stage engine rocket that is powered by solid and liquid fuel alternatively. It is a four stage engine rocket powered by solid and liquid fuel alternatively. In this flight, the 'XL' version of PSLV with six solid strap-on motors was used.
PSLV is ISRO’s versatile launch vehicle that is used for launch of multiple satellites in polar SSOs, Geosynchronous Transfer Orbit (GTO), Low Earth Orbits (LEO) and sub-GTO. It has been used for launching satellites for international customers.
Since 1994, PSLV has been used for launching 121 satellites of which 79 were from other countries and 42 were Indian satellites.
Besides, the Director of the Vikram Sarabhai Space Centre Dr Shivan said GSLV MK 3 D1; the heaviest form of the satellite will be launched by 20 January 2017. In addition to this, Director of ISAC Dr M Annadurai said that 12 more satellites will be launched in 2017 and work has been stepped up to launch Chandrayaan 2.
