Arizona-headquartered space operations company Katalyst Space Technologies has signed a contract with Arianespace to launch its NEXUS-1 satellite servicing spacecraft aboard an Ariane 6 in 2027.
The NEXUS-1 spacecraft is designed to operate in geostationary orbit (GEO), docking with satellites to perform a range of in-orbit servicing duties, including installing new hardware, repositioning satellites, and extending their operational life.
On 23 March, Katalyst Space Technologies announced that it had selected Ariane 6 to launch its NEXUS-1 spacecraft to geostationary transfer orbit aboard an Ariane 6 rocket in the second half of 2027. According to the company, the spacecraft will initially be used to service governmental customers and later commercial operators. The company did, however, not specify any specific customers or satellites in its announcement.
“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,” said Katalyst Space Technologies CEO Ghonhee Lee. “We are excited to partner with Arianespace on this important mission to deploy these capabilities for our government and commercial partners.”
Arianespace performed the first Ariane 6 flight of 2026 in February, launching the first of 18 missions for the Amazon LEO constellation on the first flight of the more powerful four-booster Ariane 64 variant. All five previous flights since its introduction in July 2024 had been conducted using the two-booster Ariane 62 variant, launching payloads for CNES, EUMETSAT, and ESA.
On 13 March, Arianespace announced that the next Ariane 6 mission in 2026 would be a second flight for Amazon, stating at the time that it would begin the launch campaign “in the coming weeks.” This likely means the flight will occur in April. In total, Arianespace expects to launch as many as eight Ariane 6 missions in 2026, most in service of fulfilling the 18-mission Amazon contract.
