    SRIHARIKOTA: Marking the first launch mission of the year 2022, Indian Space Research Organisation’s earth observation satellite EOS-04 and two small satellites were successfully placed into the intended orbit by the PSLV-C52 rocket on Monday, a feat described by the ISRO as a “marvellous accomplishment”.

    The space agency’s workhorse launch vehicle, PSLV, placed the three satellites into the intended orbit, after blasting off at 5.59 am from here amid dark, early morning skies.

    After a flight of about 19 minutes, the vehicle injected the satellites into its intended orbit, drawing instant cheers and applause from the scientists who were closely monitoring the year’s maiden mission.

    ISRO, in a tweet, said EOS-04 was placed into an intended sun synchronous polar orbit of 529 km altitude at 6.17 am.

    After first injecting EOS-04, the two small satellites INSPIREsat-1 and INS-2TD were also put into their orbits respectively.

    “The mission of PSLV-C52/EOS-04 has been successfully accomplished. The primary satellite EOS-04 has been put into a very precise orbit by PSLV-C52, and along with that, co-passenger satellites INSPIREsat-1 and INS-2TD also have been placed into right orbit,” ISRO Chairman S Somanath said after the successful launch.

    Incidentally, today’s launch also happens to be the first mission after Somanath took over as the Secretary, Department of Space and Chairman, Space Commission, recently.

    Thanking everyone for making the mission possible, he said, “this spacecraft is going to be one of the biggest assets for us to serve the country.”

    Mission Director SR Biju said “what we have accomplished today is really marvellous.”

    Earlier, the 25.30-hour countdown for today’s launch had commenced at 04:29 am on Sunday.

    EOS-04, weighing 1,710 kg and with a mission life of ten years, is a Radar Imaging Satellite designed to provide high quality images under all weather conditions for applications such as Agriculture, Forestry and Plantations, Soil Moisture and Hydrology and Flood mapping.

    INSPIREsat-1 is from Indian Institute of Space Science and Technology (IIST) in association with Laboratory of Atmospheric and Space Physics at University of Colorado Boulder, while INS-2TD is a technology demonstrator satellite from ISRO.

    This is a precursor to the India-Bhutan Joint Satellite (INS-2B).

    Two scientific payloads on INSPIREsat-1, with a mass of 8.1 kg and mission life of one year, are aimed at improving the understanding of ionosphere dynamics and the sun’s coronal heating processes.

    INS-2TD, with a mass of 17.5 kg, has a mission life of six months.

    Having a thermal imaging camera as its payload, the satellite benefits the assessment of land surface temperature, water surface temperature of wetland or lakes, delineation of vegetation (crops and forest) andcthermal inertia (day and night).

    Monday’s was the 54th flight of PSLV and 23rd mission using PSLV-XL configuration with six PSOM-XLs (strap-on motors).

  • ISRO successfully launches EOS-04, two co-passenger satellites, starts 2022 on a good note

    BENGALURU: The Indian Space Research Organisation (ISRO) on Monday morning at 6:17 am successfully launched Earth Observation Satellite EOS-04, into an intended sun-synchronous polar orbit of 529 km altitude.

    The satellite was launched from Satish Dhawan Space Centre, Sriharikota Range (SHAR), Sriharikota, about 80 Km north of Chennai.

    ISRO’s first mission of 2022, launched onboard India’s Polar Satellite Launch Vehicle PSLV-C52, lifted off at 5:59 am from the first launch pad at SHAR. This was the 80th launch vehicle mission from SDSC SHAR, Sriharikota; 54th flight of PSLV; and the 23rd flight of PSLV in the XL configuration (6 strap-on motors).

    The 1,710 kg EOS-04, which can generate 2,280 Watts power, is a Radar Imaging Satellite designed to provide high-quality images under all-weather conditions for applications such as agriculture, forestry & plantations, soil moisture & hydrology and flood mapping. The satellite with a mission life of 10 years was built at UR Rao Satellite Centre in Bengaluru.

    The PSLV-C52 also placed two small satellites – a student satellite (INSPIREsat-1) from Indian Institute of Space Science & Technology (IIST) in association with the Laboratory of Atmospheric & Space Physics at the University of Colorado, Boulder, and a technology demonstrator satellite (INS-2TD) from ISRO, which is a precursor to India-Bhutan Joint Satellite (INS-2B).

    The two co-passenger satellites were successfully separated from the PSLV in a predetermined sequence.

    ISRO Chairman Shri S Somanath congratulated team ISRO for the precision with which the mission was accomplished.

    ISRO has planned 19 missions this year, including the uncrewed  Ganaganyaan mission in December 2022, which will be the first in a series of three missions, with the third aimed at putting the first Indian astronauts into space on an indigenous mission in 2023-2024.
