    Watch the PSLV-C52/EOS-04 Launch Live Streaming. (Scheduled On: February 14, 2022, at 05:30 IST)




    PSLV-C 52 Launch Updates:








    ISRO's first launch of 2022, under the leadership of new Chairman S. Somanath, went off without a hitch, precisely positioning all three satellites in their assigned orbits. 


    The PSLV C-52 of the Indian Space Research Organization lighted up the pre-dawn black sky and Pulicat Lake with thick orange fumes as it rose into the air, breaking the early stillness with the booming roar of the launch vehicle that had three satellites on board. 


    ISRO's first launch of 2022, under the leadership of new Chairman S. Somanath, went off without a hitch, precisely positioning all three satellites in their assigned orbits. 

    At 0617 IST, PSLV-C52 inserted EOS-04 into a 529km altitude sun-synchronous polar orbit, according to the Indian Space Research Organization. 

    The PSLV C-52 was the PSLV's 54th flight and the 23rd mission to use the PSLV-XL variant. 



    PSLV-C52 launched three satellites from the first launch pad at Satish Dhawan Space Centre in Sriharikota at 5.59 a.m on Monday, including its principal payload, the EOS-04 radar imaging satellite. 



    • The EOS-04 satellite was put in a solar synchronous orbit 17 minutes after launch. 
    • The rocket then inserted the two additional satellites, INS-2TD and Inspiresat-1, a minute later. 
    • The fourth stage was passivated to remove residual propellants four minutes after lift-off, using mixed oxides of nitrogen (MON) passivation followed by mono methyl hydrazine (MMH) passivation, two propellants that power PSLV's upper stage. 
    • The passivation process lasted ten minutes. 
    • Passivation is the process of removing any remaining fuel from a rocket to avoid the higher stages from exploding. 
    • The top stage burns inactively or vents the leftover propellants. 


    PSLV's 54th flight and 23rd mission with six PSOM-XLs used the PSLV-XL configuration. 


    "The main satellite, EOS-04, has been placed in a very exact orbit by PSLV-C52," Isro chairman S Somanath stated, congratulating the crew. 

    The INS-2TD and INSPIREsat-1 co-passenger satellites have also been put in the proper orbits. 

    This spacecraft will be one of the most valuable assets in the country's arsenal. 

    We will come back with another PSLV launch very soon." 


    "First and foremost, let me congratulate the PSLV crew for the exact inject of EOS-04," Srikanth remarked. 

    The launch has re-energized the ISRO crew. 

    The most awaited spacecraft, EOS-04, is an earth observation mission that will serve the country in agriculture, soil moisture, disaster management, disaster assessment, carbon inventory, forest and plantation management, and many other sectors with indigenously developed state-of-the-art technology SAR." 


    "After separation, EOS-04's health is in fantastic condition. 

    I'm pleased to report that the solar panels have been deployed autonomously and have begun to provide the desired electricity.... 

    The satellite will be ready to offer the first sight of photos in a few days following calibration and outgassing. 

    Many government services will be enhanced by the services. 

    EOS-04 is a minor step toward the country's objective of opening the space sector with industry engagement in the form of build to print, as well as assemble and test. 

    We were able to achieve a reasonable level of success in our endeavor." 


    The launch's success was critical for ISRO, who had a quiet 2020 with just two launches, one of which, the GSLVF10, crashed shortly after launch. 



    On Monday, the PSLV C-52, carrying the Earth Observation Satellite EOS 04, the INS-2TD, an ISRO technology demonstrator, and the INSPIREsat-1, a student satellite, launched from the Satish Dhawan Space Centre, SHAR, Sriharikota, at 5.59 a.m. 


    The three satellites were separated and sent into their orbits 18 minutes later. 


    "The EOS 04, the principal spacecraft, has been placed in a precise orbit. 

    The co-passenger satellites have been positioned in the proper orbit," Mr. Somanath said, adding that ISRO would "be back with the next PSLV launch very shortly." 



    • The EOS-4, a radar imaging satellite with a 10-year mission life, is intended to deliver high-quality pictures in all weather circumstances for agricultural, forestry, plantation, flood mapping, soil moisture, and hydrological applications. 
      • According to ISRO, the satellite would acquire earth observation data in the C-band, complementing and supplementing data from the Resourcesat, Cartosat, and RISAT-2B series. 

    • The INS-2TD will measure land and water surface temperatures, agricultural and forest delineation, and thermal inertia as a forerunner to the India-Bhutan joint satellite [INS 2-B]. 

    • INSPIREsat-1 is a student satellite developed by the Indian Institute of Space Science and Technology in collaboration with the University of Colorado in the United States. 

      • Its goal is to improve knowledge of ionosphere dynamics and coronal heating processes on the Sun. 



    On Monday, Prime Minister Narendra Modi congratulated India's space experts on the success of the PSLV C52 mission launch. 


    "Congratulations to our space experts on the successful launch of PSLV C52 mission," Mr. Modi tweeted.
