Sirius Space Services will launch its first rocket in 2026, followed by further launches the following year as part of a “multi-year, multi-launch” agreement.
ELA also revealed it was in the “final stages of negotiations” with three more rocket firms to become long-term tenants, with announcements expected shortly.
“We absolutely love working with Sirius, who we believe are amongst the most mature and advanced launch service providers we work with,” said ELA chief executive Michael Jones.

“We first visited Antoine Fourcade, Co-founder and CEO, and Francois Maroquene-Froissart Co-founder and CTO in their offices in La Defence (Paris) nearly three years ago. We have visited numerous times, and they have joined us in Adelaide and at the Arnhem Space Centre (ASC).”
ELA plans to accommodate up to seven resident launchers initially, but the site has the potential to grow further. It will also rent out launchpads and services for one-off, ad-hoc blast-offs.
“The campaign will begin with the development and test flights of SIRIUS 1 in 2026, followed by launches of the larger SIRIUS 13 (800kg payload capacity) in 2027,” said ELA.
“The flexibility to access a range of orbits, including medium and low inclination orbits, SSO and equatorial, along with ELA’s full-service offering, were the key reasons behind the decision by Sirius to sign with ELA for launches from the ASC.

“Sirius’ has an innovative approach to rocket engine design, which comprises metal additive manufacturing / 3D printing using copper and nickel-chromium superalloys. Its STAR-1 engine is fuelled by liquid oxygen and methane, producing 55kN of thrust.”
The news comes a year after ELA revealed Innospace would become the first long-term tenant at the Arnhem Space Centre and following a separate announcement that Singaporean rocket firm Equatorial Space Systems (ESS) would perform suborbital launches later this year.
ELA’s spaceport is one of four in Australia, competing against rivals Southern Launch in SA, which has two, and Gilmour Space Technologies in Queensland.
Despite its recent flurry of commercial deals, ELA is best known for blasting off three NASA rockets in 2022, in a landmark moment for the local sector.
