    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.

    What Is The SSLV Rocket?



      What Is SSLV?

      The Small Satellite Launch Vehicle (SSLV) is an ISRO-developed small-lift launch vehicle with a payload capacity of 500 kg (1,100 lb) to low Earth orbit (500 km (310 mi)) or 300 kg (660 lb) to Sun-synchronous orbit (500 km (310 mi)) for launching small satellites, as well as the ability to support multiple orbital drop-offs. 




      SSLV is designed with low cost and quick turnaround in mind, with launch-on-demand flexibility and minimum infrastructure needs. 

      The SSLV-D1 launched from the First Launch Pad on August 7, 2022, but failed to reach orbit. 

      SSLV launches to Sun-synchronous orbit will be handled in the future by the SSLV Launch Complex (SLC) at Kulasekharapatnam in Tamil Nadu




      After entering the operational phase, the vehicle's manufacture and launch operations would be handled by an Indian consortium led by NewSpace India Limited (NSIL). 


      What Is The Origin And Evolution Of SSLV?



      The SSLV was created with the goal of commercially launching small satellites at a far lower cost and with a greater launch rate than the Polar Satellite Launch Vehicle (PSLV)

      SSLV has a development cost of 169.07 crore (US$21 million) and a production cost of 30 crore (US$3.8 million) to 35 crore (US$4.4 million). 

      The expected high launch rate is based on mostly autonomous launch operations and simplified logistics in general. 

      In comparison, a PSLV launch employs 600 officials, but SSLV launch procedures are overseen by a tiny crew of about six persons. 



      The SSLV's launch preparation phase is predicted to be less than a week rather than months. 



      The launch vehicle may be erected vertically, similar to the current PSLV and Geosynchronous Satellite Launch Vehicle (GSLV), or horizontally, similar to the decommissioned Satellite Launch Vehicle (SLV) and Augmented Satellite Launch Vehicle (ASLV)


      The vehicle's initial three stages employ HTPB-based solid propellant, with a fourth terminal stage consisting of a Velocity-Trimming Module (VTM) with eight 50 N reaction control thrusters and eight 50 N axial thrusters for altering velocity. 


      SSLV's first and third stages (SS1) are novel, while the second stage (SS2) is derived from PSLV's third stage (HPS3). 



      Where Is The SSLV Launch Complex?



      Early developmental flights and those to inclined orbits would launch from Sriharikota, first from existing launch pads and ultimately from a new facility in Kulasekharapatnam known as the SSLV Launch Complex (SLC). 

      In October 2019, tenders for production, installation, assembly, inspection, testing, and Self Propelled Launching Unit (SPU) were announced. 

      When completed, this proposed spaceport at Kulasekharapatnam in Tamil Nadu would handle SSLV launches to Sun-synchronous orbit. 


      What Is The History Of The SSLV?

      Rajaram Nagappa recommended the development route of a 'Small Satellite Launch Vehicle-1' to launch strategic payloads in a National Institute of Advanced Studies paper in 2016. 



      S. Somanath, then-Director of Liquid Propulsion Systems Centre, acknowledged a need for identifying a cost-effective launch vehicle configuration with 500 kg payload capacity to LEO at the National Space Science Symposium in 2016, and development of such a launch vehicle was underway by November 2017. 



      The vehicle design was completed by the Vikram Sarabhai Space Centre (VSSC) in December 2018. 

      All booster segments for the SSLV first stage (SS1) static test (ST01) were received in December 2020 and assembled in the Second Vehicle Assembly Building (SVAB). 

      On March 18, 2021, the SS1 first-stage booster failed its first static fire test (ST01). 

      Oscillations were detected about 60 seconds into the test, and the nozzle of the SS1 stage disintegrated after 95 seconds. 

      The test was supposed to last 110 seconds. 

      SSLV's solid first stage SS1 must pass two consecutive nominal static fire tests in order to fly. 

      In August 2021, the SSLV Payload Fairing (SPLF) functional certification test was completed. 

      On 14 March 2022, the second static fire test of SSLV first stage SS1 was performed at SDSC-SHAR and satisfied the specified test goals. 


      How Will The Small Satellite Launch Vehicle (SSLV) Be Manufactured?

      ISRO has begun development of a Small Satellite Launch Vehicle to serve the burgeoning global small satellite launch service industry. 

      NSIL would be responsible for manufacturing SSLV via Indian industry partners. 

       

      What Are The Unique Features Of The Small Satellite Launch Vehicle (SSLV)?

      SSLV has been intended to suit "Launch on Demand" criteria while being cost-effective. 

      It is a three-stage all-solid vehicle capable of launching up to 500 kilograms satellites into 500 km LEO. 

      What Are The Expected Benefits Of The SSLV Rocket?

      Reduced Turn-around Time Launch on Demand Cost Optimization.

      Realization and Operation Ability to accommodate several satellites.

      Minimum infrastructure required for launch Design practices that have stood the test of time.

      The first flight from SDSC SHAR was originally scheduled during the fourth quarter of 2019. It occurred only in August of 2022.

      Following the first developmental flights, ISRO plans to produce SSLV via Indian Industries through its commercial arm, NSIL. 


      What Is The Operational Performance History Of The SSLV?


      The SSLV's maiden developmental flight was place on August 7, 2022. 

      SSLV-D1 was the name of the flying mission. 

      The SSLV-D1 flight's mission goals were not met. 

      The rocket featured three stages and a fourth Velocity Trimming Module (VTM). 

      The rocket stood 34m tall, with a diameter of 2m, and a lift-off mass of 120t in its D1 version. 

      The rocket launched EOS 02, a 135 kilograms Earth observation satellite, and AzaadiSAT, an 8 kg CubeSat payload designed by Indian students to promote inclusion in STEM education. 


      The SSLV-D1 was planned to deploy the two satellite payloads in a circular orbit with a height of 356.2 km and an inclination of 37.2°. 

      The ISRO's stated reason for the mission's failure was software failure. 

      The mission software identified an accelerometer anomaly during the second stage separation, according to the ISRO. 

      As a result, the rocket navigation switched from closed loop to open loop guidance. 

      Despite the fact that this change in guiding mode was part of the redundancy incorporated into the rocket's navigation, it was not enough to save the mission. 

      During open loop guiding mode, the last VTM stage only fired for 0.1s rather than the required 20s. 

      As a result, the two satellites and the rocket's VTM stage were injected into an unstable elliptical 35676 km orbit. 

      The SSLV-final D1's VTM stage had 16 hydrazine-fueled (MMH+MON3) thrusters. 

      Eight of them were to regulate the orbital velocity and the other eight were to control the altitude. 

      During the orbital insertion maneuvers, the VTM stage also controlled pitch, yaw, and roll. 

      The SSLV-three D1's major stages all worked well. 

      However, this was insufficient to provide enough thrust for the two satellite payloads to establish stable orbits. 

      The VTM stage required to burn for at least 20 seconds to impart enough extra orbital velocity and altitude adjustments to put the two satellite payloads into their designated stable orbits. 

      Instead, the VTM activated at 653.5s and shut down at 653.6s after lift-off. 

      After the VTM stage was partially fired, the EOS 02 was released at 738.5s and AazadiSAT at 788.4s after liftoff. 

      These failures occurred, causing the satellites to reach an unstable orbit and then be destroyed upon reentry. 



      What Was The Performance Outcome Of The SSLV D1 Mission?

      SSLV's maiden developmental flight. 

      The mission goal was a circular orbit of 356.2 km height and 37.2° inclination. 

      Two satellite payloads were carried on the trip. 


      1. The 135-kilogram EOS-02 Earth observation satellite 
      2. and the 8-kilogram AzaadiSAT CubeSat. 


      Due to sensor failure and flaws in onboard software, the stage and two satellite payloads were put into an unstable elliptical orbit of 35676 km and then destroyed upon reentry. 

      The mission software, according to the ISRO, failed to detect and rectify a sensor malfunction in the VTM stage. 

      The last VTM stage only fired momentarily (0.1s). 


      What Were The Overall Lessons From The SSLV-D1/EOS-02 Mission?



      Mission ISRO developed a small satellite launch vehicle (SSLV) to launch up to 500 kilograms satellites into Low Earth Orbits on a 'launch-on-demand' basis . 


      The SSLV-D1/EOS-02 Mission's first developmental flight was slated for August 7, 2022, at 09:18 a.m. 

      (IST) from the Satish Dhawan Space Centre's First Launch Pad in Sriharikota. 

      The SSLV-D1 mission would send EOS-02, a 135 kilograms satellite, into a low-Earth orbit 350 kilometers above the equator at an inclination of roughly 37 degrees. 

      The mission also transports the AzaadiSAT satellite. 

      SSLV is built with three solid stages weighing 87 t, 7.7 t, and 4.5 t. 

      The satellite is inserted into the desired orbit using a liquid propulsion-based velocity trimming module. 

      • SSLV is capable of launching Mini, Micro, or Nanosatellites (weighing between 10 and 500 kg) into a 500 km planar orbit. 
      • SSLV gives low-cost on-demand access to space. 
      • It has a quick turnaround time, the ability to accommodate numerous satellites, the ability to launch on demand, minimum launch infrastructure needs, and so on. 



      SSLV-D1 is a 34-meter-tall, 2-meter-diameter vehicle with a lift-off mass of 120 tonnes. 

      ISRO developed and built the EOS-02 earth observation satellite. 



      This microsat class satellite provides superior optical remote sensing with excellent spatial resolution in the infrared spectrum. 

      The bus configuration is based on the IMS-1 bus. 

      AzaadiSAT is an 8U Cubesat that weighs around 8 kg. 

      It transports 75 distinct payloads, each weighing roughly 50 grams and performing femto-experiments. 

      These payloads were built with the help of female students from rural areas around the nation. 

      The payloads were assembled by the "Space Kidz India" student team. 

      A UHF-VHF Transponder operating on ham radio frequency to allow amateur radio operators to transmit speech and data, a solid state PIN diode-based Radiation counter to detect the ionizing radiation in its orbit, a long-range transponder, and a selfie camera are among the payloads. 

      The data from this satellite was planned to be received using the ground system built by 'Space Kidz India.'  

      Both satellite missions have failed as a result of the failure of SSLV-D1's terminal stage.



      When Is The SSLV D2 Planned To Lift Off?

      The SSLV's second developmental flight is planned for November of 2022. 

      It is intended to transport four Blacksky Global satellites weighing 56 kg to a 500 km circular orbit with a 50° inclination.  

      It will place the X-ray polarimeter satellite into low Earth orbit(LEO).

      ISRO GISAT-1 - WATCH LIVE STREAMING - LAUNCH UPDATES



      UPDATE (6 am IST, Aug. 12th 2021) - Anomaly observed during the cryogenic engine phase of the GSLV F-10 launch vehicle. Mission could not be completed successfully as planned.





      According to authorities, the Indian space agency is conducting pre-rocket launch operations at its rocket port in Sriharikota, Andhra Pradesh, in preparation for the launch of its earth observation satellite EOS-03 or Geo Imaging Satellite-1 (GISAT-1) early on Thursday. 


      • While ISRO authorities remain tight-lipped on the launch,  it has been learned that the rocket—the Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10)—is on its way to the second launch pad, laden with GISAT-1, and is set to blast off at 5.43 a.m. 




      The GISAT-1 will be the country's first geostationary orbiting sky eye or earth observation satellite. 


      • Just over 18 minutes into its journey, the 51.70-meter-tall, 416-ton GSLV-F10 will put GISAT-1 in the geosynchronous transfer orbit (GTO), from where the satellite will be lifted to its ultimate location using its onboard engines. 
      • In contrast to other remote sensing satellites in a lower orbit that can only come over a location at regular intervals, once put in geostationary orbit, the satellite will keep a constant eye on the areas of interest, moving in rhythm with the rotation of the globe and so seeming stationary. 




      The GISAT-1 was originally scheduled to launch on March 5, 2020, however the ISRO announced the mission's delay only hours before launch due to a technical issue. 


      • The COVID-19 epidemic and subsequent lockdown caused the mission to be postponed. 
      • It was necessary to disassemble and clean up the rocket. 
      • Following that, the GISAT-1 launch was scheduled for March 2021, however it was again postponed due to issues with the satellite's battery. 
      • The satellite and rocket were getting prepared for their flight at Sriharikota after the battery was replaced when the second wave of COVID-19 swept in, infecting several at the rocket launch center. 






      The 2,268 kilogram GISAT-1, according to the Indian space agency, would give a real-time picture of a wide area of the region of interest at regular intervals. 




      • It will also allow for immediate monitoring of natural catastrophes, episodic occurrences, and any other short-term phenomena. 
      • The satellite's payload imaging sensors will include a 42-meter resolution six-band multi-spectral visible and near-infrared sensor, 318-meter resolution 158-band hyper-spectral visible and near-infrared sensor, and 191-meter resolution 256-band hyper-spectral short wave infrared sensor. 
      • For the first time, a four-metre diameter Ogive shaped payload fairing (heat shield) constructed of composite would be utilized in the rocket, according to ISRO. 







      After the GISAT-1 launch, the EOS-4 or Risat-1A.



      RISAT 1A  is a radar imaging satellite with Synthetic Aperture Radar (SAR) that can capture images day and night seeing through clouds, would be launched, according to ISRO. 


      • The Polar Satellite Launch Vehicle (PSLV) will launch the Risat-1A satellite, which weighs over 1,800 kg, in September, according to ISRO. 
      • The Risat-1A is a follow-on microwave remote sensing satellite to Risat-1, and is designed to guarantee SAR in C-Band continuity while also delivering microwave data to the user community for operational purposes. 
      • With a mission life of five years and the capacity to operate day, night, and in all weather situations, the satellite will play a critical role in the nation's defense. 



      Among other things, the satellite features high-capacity data handling systems and storage devices. 


      • The satellite, according to the ISRO, will offer image data for a variety of applications linked to land, water, and the environment, including agriculture, forestry, and water resource management. 
      • An ISRO official previously said that an earth observation satellite would transmit images that will be utilized by various agencies based on their requirements. 
      • In 2012, a PSLV rocket launched the 1,858 kg Risat-1 satellite. It lasted five years on the mission.





      DESCRIPTION OF THE MISSION





      From the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota, India's Geosynchronous Satellite Launch Vehicle-F10 (GSLV-F10) will launch the Geo Imaging Satellite-1 (GISAT-1) satellite. From the Second Launch Pad, the launch will take place.



      • For the first time in GSLV history, a 4 meter diameter Ogive shaped payload fairing (OPLF) is flown to accommodate a larger spacecraft.
      • GISAT-1 is the first state-of-the-art agile Earth observation satellite that GSLV-F10 will put into a Geosynchronous Transfer Orbit. The satellite will next use its onboard propulsion engine to reach geostationary orbit.
