This is EOS-4, an Indian Earth-imaging satellite originally designated as RISAT-1A (Radar Imaging Satellite).

The satellite is being developed by the Indian Space Research Organisation and will be the 6th in the series of RISAT satellites.

EOS-4 will be a land-based mission with its primary application being terrain mapping and analysis of land, ocean, and water surface for soil moisture.

This mission will also carry two rideshare payloads, INS-2TD and INSPIREsat-1.

INS-2TD is a technology demonstrator satellite from the ISRO, which is a precursor to India-Bhutan Joint Satellite {INS-2B}.

INSPIREsat-1 is a student satellite from the Indian Institute of Space Science & Technology in association with the Laboratory of Atmospheric & Space Physics at the University of Colorado, Boulder.

The Polar Satellite Launch Vehicle - XL (PSLV-XL) is the six side-mounted solid rocket booster configuration of the overall PSLV family of expendable rockets flown by India.

It is the most-used rocket of the PSLV line and is capable of launching missions to the Moon and Mars.

Its first flight occurred on October 22nd, 2008.

The rocket uses a mixture of solid and liquid propellant stages to get to orbit. The first stage, also called the core, is a solid propellant rocket, and the six side-mounted solid propellant boosters are bolted to it.

A liquid fueled second stage then takes over, followed by a third stage that is powered by solid propellant.

A liquid fueled fourth stage serves as the final part of the rocket. The engines on this stage are restartable to place satellites into their proper orbits.

Satish Dhawan Space Centre or Sriharikota Range is a rocket launch center operated by the Indian Space Research Organisation. It is located in Sriharikota in Andhra Pradesh.

Chosen for its remote location, the center became operational in 1971 and hosted its first launch that year for a suborbital mission.

The first orbital launch took place on August 10, 1979.

The spaceport received its current name in 2005 when it was named in honor of Satish Dhawan, the former head of the Indian Space Research Organisation.

The facility has two launch pads and will be the base of India's upcoming human spaceflight program.
