Electron's 90th Flight Put On Hold

In a post on X, Rocket Lab said the launch date is being adjusted to allow for additional pre-flight checkouts. "Mission update: The launch date for the 'Ten Owl Of Ten' mission for Synspective is being adjusted to conduct additional checkouts before launch. Standby for the new launch date soon," the company said.

The mission had been scheduled to launch no earlier than June 18 NZT from Launch Complex 1 in New Zealand. The mission will carry a single StriX synthetic aperture radar (SAR) satellite into a 552-kilometer low-Earth orbit for Japan-based Synspective. While Rocket Lab did not disclose the nature of the additional checks, the delay pushes back the Electron's milestone 90th flight.

Earlier this week, the company said the StriX satellite had already been encapsulated inside the Electron rocket and was ready for launch preparations. The "Ten Owl Of Ten" mission will mark Rocket Lab's tenth dedicated launch for Synspective, one of the company's longest-running commercial customers.

RKLB's Synspective Partnership Stays On Track 

Rocket Lab has served as Synspective's sole launch provider since 2020, helping deploy the company's growing SAR imaging constellation over Japan. The StriX satellites provide Earth-observation data used for urban development planning, infrastructure monitoring, construction projects and disaster response.

The upcoming mission follows last month's successful "Viva La StriX" launch, which deployed Synspective's ninth satellite and marked Rocket Lab's 88th Electron mission overall. As part of the partnership, Rocket Lab has even developed custom Electron fairings tailored specifically for Synspective's satellites, helping maintain a perfect mission success record for StriX deployments.

Despite the scheduling adjustment, Rocket Lab still has another 17 Synspective missions under contract through 2030.
