The countdown to Isro's first launch mission of 2022 begins tomorrow.

The Indian Space Research Organisation (ISRO) will launch PSLV-C52, an earth observation satellite, into orbit on February 14 at 5.59 a.m., with the countdown beginning on Sunday morning. This is the Isro's first launch mission of the year. PSLV-C52 is designed to place the 1710 kg EOS-04 into a 529 km sun-synchronous polar orbit, according to Isro.

Here is all you need to know about the mission:

1. The PSLV-C52 will be launched from Sriharikota's Satish Dhawan Space Centre's First Launch Pad. 

2. According to the space agency, EOS-04 is a Radar Imaging Satellite designed to provide high-quality images in all weather conditions for applications such as agriculture, forestry and plantations, soil moisture and hydrology, and flood mapping. 

3. The mission will also carry two small satellites as co-passengers: an Indian Institute of Space Science and Technology student satellite (INSPIREsat-1) in collaboration with the University of Colorado Boulder's Laboratory of Atmospheric and Space Physics, and an Isro technology demonstrator satellite, INS-2TD. INS-2TD is a forerunner to the India-Bhutan Joint Satellite INS-2B.
