A viral claim on social media alleged that the Eris rocket, Australia’s first orbital rocket which crashed shortly after launch on July 30, 2025 was powered by an engine manufactured by the Indian Space Research Organisation (ISRO).
The rocket was manufactured by Gilmour Space Technologies but the claim implies that the crash was due to an Indian-made engine. An X account by the handle ‘TacticalTribun’ shared this claiming that the Australia’s satellite launched failed 14 seconds after takeoff and the rocket had an ISRO-made engine. Find the post here
Similar claims have been made in other social media channels with some blaming the Modi Government for the failure. Check the screenshot below.
FACT CHECK
DigitEYE India investigated the claim and searched for evidence to clarify the facts surrounding the incident. The first ever Australian orbit rocket was launched on 30 July 2025 but there are no credible sources to prove that it had an ISRO-made engine.

However, there were no official reports or announcements by ISRO pertaining to any collaboration with Gilmour Space Technologies. The Eris rocket, developed by Gilmour Space Technologies, marked Australia’s first orbital launch attempt in over 50 years.
Launched from the Bowen Orbital Spaceport in Queensland, the 23-meter rocket lifted off successfully but crashed back to Earth after 14 seconds.
Despite the failure, Gilmour Space Technologies highlighted the launch as a milestone, noting that the rocket’s four hybrid-propelled engines ignited for 23 seconds, providing critical data for future missions. The Australia Today highlights this “strong result” in their tweet which can be found here.
🚀 Australia’s first homegrown orbital rocket lifts off — and crashes in 14 seconds
The 23-metre Eris rocket by @GilmourSpace fired all four engines and cleared the launch pad before crashing — still called a “strong result” for local innovation.

Credible media outlets, including a report by AP News and The Guardian, asserted that the rocket was entirely designed and built by Gilmour Space Technologies, a Gold Coast-based Australian company.
Moreover, we came across statements from Gilmour Space Technologies including remarks by CEO Adam Gilmour, emphasized the rocket’s indigenous development and made no reference to foreign components, let alone ISRO.
The official press release clearly states that the “orbital-class rocket designed and built entirely in Australia” and how “Eris was developed almost entirely in-house.”
Thus, the assertion that the Eris rocket contained an ISRO-made engine is false, with no supporting evidence from credible sources or official statements. The rocket was a fully Australian endeavor and there has been no collaboration with ISRO.
