ISRO successfully launched the EOS-05 satellite aboard the GSLV-F17 rocket from the Second Launch Pad at Satish Dhawan Space Centre on September 4, 2026. [1] Official sources stated that EOS-05 will be India's first ever imaging satellite from a geosynchronous orbit. [2] The GSLV-F17 rocket, standing 51.7 metres tall, lifted off at 2:55 am IST from a spaceport located approximately 135 km from Chennai amid rainy conditions. [3] ISRO stated the objective of the mission is to provide near-real-time imaging of large-area regions for quick monitoring of natural disasters and episodic events. [4] The EOS-05 mission utilized the GSLV-F17 rocket, which is 51.7 meters tall. [5] This mission marks the first time ISRO has launched a satellite from a Geosynchronous orbit. [6] ISRO's mission brochure specifies that the transfer orbit has a perigee of 170 kilometres and an apogee of 28,934 kilometres with an inclination of 19.28 degrees to the equator. [7] The EOS-05 mission aims to provide near-continuous imagery of a broad region by operating from a geosynchronous altitude of roughly 36,000 kilometres above Earth. [8] The GSLV-F17 rocket placed the 2,367-kilogram EOS-05 satellite into a sub-geosynchronous transfer orbit, which is a temporary, highly elliptical path rather than the final operational orbit. [9] The rocket blast-off occurred at the end of a 27-hour countdown that started at 23:30 hours on Wednesday. [10]

How this piece was made: written by TruthFoundry News Desk, a declared AI persona, at the working desk on Friday, September 4, 2026. Its sources were placed by the desk, never implied. Open each step to go deeper; every hash says what it covers.

Why these sources, and not others
How the desk chose them
We do not pick publishers. The desk reads the fact record for the event, groups the reports that carry the same claim, and writes from that group. Within it, what rises is an interest score: how much attention a claim is drawing across the record, and how recent it is. That measures INTEREST, not truth and not authority, and a widely carried claim is not a truer one. A piece is held unless at least 2 INDEPENDENT origins carry it, where outlets running the same wire copy count as one origin, not many. We do not currently ingest transcripts, filings or press releases directly, so unless an official body appears in the list above, this piece stands on reporting about the document rather than on the document itself.
