Why ISRO turned to SpaceX: Ex-chiefs explain GSAT-N2 launch decision

India sought the assistance of SpaceX, a company founded by Elon Musk, to launch its newest communication satellite, GSAT-N2. This decision stems from the limitations of India's current launch vehicles, which cannot handle payloads exceeding 4,000 tonnes, as explained by former officials from the Indian Space Research Organisation (ISRO).

The satellite was successfully placed into orbit by SpaceX's Falcon 9 rocket from a US launch site. Weighing 4,700 kg, the GSAT-N2 is a high-throughput satellite designed to boost broadband services and in-flight connectivity throughout India, according to NewSpace India Limited (NSIL), ISRO's commercial arm.

Former ISRO chairperson K Sivan stated, "The satellite (launched by SpaceX) was a heavier one beyond the capability of ISRO launch vehicles, that's why it has gone outside." He further explained that ISRO's current capacity is capped at four tonnes, falling short of the 4.7-tonne weight of GSAT-N2. However, Sivan assured that efforts are underway to increase the capabilities of ISRO launch vehicles.


This high-band communication satellite will extend connectivity to even the most remote areas of India. Another former ISRO chief, G Madhavan Nair, confirmed that India's lack of a launch vehicle capable of handling the 4.7-tonne satellite led to the decision to partner with SpaceX. He added, "ISRO has plans to double its next generation vehicles capacity, but we can't wait until then, so they opted for SpaceX."
