ISRO’s GISAT-1 satellite fails to reach orbit, mission to be re-scheduled

ISRO on August 12, 2021, launched the Geo-Imaging Satellite (GISAT-1) on the Geosynchronous Satellite Launch Vehicle- F10 (GSLV-F10) but GSLV-F10/EOS-03 satellite mission failed to reach orbit. Read all you need to know.

Indian Space Research Organization (ISRO) on August 12, 2021, launched the Geo-Imaging Satellite (GISAT-1) ‘EOS-03’ on the Geosynchronous Satellite Launch Vehicle- F10 (GSLV-F10) at 5.43 am IST from the Satish Dhawan Space Centre (SDSC) at Sriharikota, Andhra Pradesh.

However, the GSLV-F10/EOS-03 satellite mission failed to reach orbit due to a technical setback in the Cryogenic Upper Stage ignition. The performance of the rocket’s first and second stages went as planned.

Dr Jitendra Singh, Union Minister of State Science & Technology and Earth Sciences (Independent Charge) after speaking with Dr K Sivan, Chairman, ISRO, said that the GSLV-F10/EOS-03 satellite mission can be re-scheduled.

ISRO: Countdown for launch of GSLV-F10/EOS-03 satellite mission commences

Countdown for the launch of GSLV-F10/EOS-03 satellite mission had commenced on August 11, 2021, at 3.43 am IST from Satish Dhawan Space Centre (SDSC), Sriharikota.

ISRO in a series of tweets informed that filling of the oxidizer and propellant for the second stage (GS2) as well as the filling of propellant for the liquid strap-on (L40) of the Geosynchronous Satellite Launch Vehicle- F10 (GSLV-F10) has been completed. Further updates are awaited from the Indian space agency.

The Geo-Imaging Satellite (GISAT-1) ‘EOS-03’ has been accorded the status of India’s eye in the sky. The satellite has been given a strategic and civilian importance as it will aid India in monitoring areas of interest and provide real time data while moving in sync with the rotation of the Earth unlike other remote sensing satellites that only cover areas at regular intervals.

ISRO to launch Geo-Imaging Satellite ‘EOS-03’ on GSLV-F10 on August 12

•The Indian Space Research Organization (ISRO) on August 10, 2021, had announced that the Geo-Imaging Satellite-1 (GISAT-1) ‘EOS-03’ will be launched on the Geosynchronous Satellite Launch Vehicle- F10 (GSLV-F10) on August 12, 2021.

•The GISAT-1 ‘EOS-03’ satellite will be launched from the Second Launch Pad of Satish Dhawan Space Centre, Sriharikota at 5.43 am IST.

•The GSLV-F10 launch vehicle will place the GISAT-1 ‘EOS-03’ satellite in the Geosynchronous Transfer Orbit and the satellite will further use its onboard propulsion system to reach the final geostationary orbit.

•The GISAT-1 ‘EOS-03’ satellite is the first GSLV flight that will be carrying a 4-metre diameter Ogive-shaped payload fairing (OPLF). This launch will mark the 14th flight of GSLV.

ISRO’s Geo-Imaging Satellite-1 (GISAT-1) ‘EOS-03’ to be launched in third quarter of 2021

Dr Jitendra Singh, Union Minister of State Science & Technology and Earth Sciences (Independent Charge), on July 29, 2021, had announced that the Department of State is prepared to launch ISRO’s Geo-Imaging Satellite-1 (GISAT-1) ‘EOS-03’ in the third quarter of 2021.

What is GISAT-1 ‘EOS-03’?

•The EOS-03 is a Geo-Imaging Satellite-1 (GISAT-1) is the first state-of-the-art agile Earth Observation Satellite that has been developed by the Indian Space Research Organization (ISRO) for Earth Observation purposes.

•The Geosynchronous Satellite Launch Vehicle- F10 (GSLV-F10) will place the GISAT-1 ‘EOS-03’ in the Geostationary Transfer Orbit.

•The GISAT-1 ‘EOS-03’ satellite is the first GSLV flight that will be carrying a 4-metre diameter Ogive-shaped payload fairing (OPLF). This launch will mark the 14th flight of GSLV.

Significance of GISAT-1 ‘EOS-03’

The GISAT-1 ‘EOS-03’ satellite will enable:

•Real-time monitoring of natural disasters such as cyclones and floods in the country.

•Real-time imaging the entire country at least four to five times every day

•Aid in monitoring the crops, water bodies, forest cover changes, vegetation condition, cloud properties, oceanography, snow, and glaciers.

ISRO’s Earth Observation Satellites

•Indian Space Research Organization (ISRO) launched its first Earth Observation Satellite in 1988 which is known as IRS-1A.

•ISRO has placed several Earth Observation Satellites in the Sun-synchronous orbit and Geostationary orbit.

•EOS-01 was launched on November 7, 2020. The EOS-01 is an Earth Imaging Satellite is a part of India’s RISAT series. The satellite is used for agriculture, forestry, and disaster management support.

•Other Earth Observation Satellites are OCEANSAT-2, RISAT-1 and 2, CARTOSAT-1, 2, 2A, 2B, RESOURCESAT-1, 2, 2A, SCATSAT-1, SARAL, Megha-Tropiques, INSAT-3D, INSAT -3DR, INSAT 3A, and Kalpana.

First developmental flight of the Small Satellite Launch Vehicle (SSLV)

•Singh further stated that the first developmental flight of the Small Satellite Launch Vehicle (SSLV) will be conducted in the fourth quarter of 2021 from Satish Dhawan Space Centre, Sriharikota.

•SSLV has been developed by ISRO as a cost-effective, three-stage launch vehicle with a payload capability of 500-kg to 500-km planar orbit or 300-kg to Sun-synchronous Polar orbit.

•With flexible nozzle control, electro-mechanical actuators for all stages, velocity trimming module, and miniaturized avionics make SSLV an ideal launch vehicle for on-demand, quick launch sessions of small satellites.
