Katalyst Selects Arianespace to Launch GEO Mission Aboard Ariane 6

Arianespace announced today that it has signed a contract with U.S. based Katalyst Space Technologies to launch the NEXUS-1 spacecraft to geostationary transfer orbit using the Ariane 6 from the European Spaceport in French Guiana. 

Slated for launch aboard Ariane 6 in the second half of 2027, the NEXUS-1 will provide in-orbit servicing capabilities, including rendezvous and docking with satellites to deliver hardware upgrades, refueling, and life-extension services. The first servicing mission for NEXUS-1 will be for the US government. NEXUS-1 also has subsequent in-orbit operations on order from commercial satellite companies.

Through this mission, Katalyst Space Technologies aims to expand the role of in-space servicing in satellite operations. Its technology enables satellites to be upgraded after launch, allowing operators to add new capabilities and extend the value of their spacecraft over time.

The Ariane 6, which has successfully performed all six of its launches to date, is Europe's proven, state of the art, heavy-lift workhorse vehicle. 

“We are delighted to sign this Ariane 6 launch contract with Katalyst. We are all about launching ambitions worldwide with Europe's powerful heavy-lift launcher Ariane 6, able to support complex and innovative space missions, like Katalyst's NEXUS-1,” said David Cavaillolès, CEO of Arianespace.

Ghonhee Lee, CEO, Katalyst Space Technologies, commented: “Katalyst is building the infrastructure required for dynamic space operations. Securing our Ariane 6 launch is a major step toward delivering on-orbit capabilities that allow satellite operators to adapt, respond, and extend mission value in ways they never could before. We are excited to partner with Arianespace on this important mission to deploy these capabilities for our government and commercial partners.”
