Rocket Lab targets 09:30 UTC launch

Rocket Lab set a 09:30 UTC target on May 22 for its Electron mission “Viva La StriX” from Launch Complex 1 on New Zealand’s Mahia Peninsula, according to the company’s mission page. The flight is carrying a single StriX Earth-observation satellite for Tokyo-based Synspective. (rocketlabcorp.com) Rocket Lab said the mission is a dedicated launch to a 572-kilometer low Earth orbit. Synspective said on April 30 that the launch window for its ninth StriX satellite would open on May 22 UTC and could shift because of weather or other complications. ### Which satellite is on this Electron mission? (rocketlabcorp.com) Synspective said the payload is its ninth StriX synthetic-aperture radar, or SAR, satellite. The company describes itself as a SAR satellite data and analytics provider, and said the spacecraft is part of its StriX series. Rocket Lab said the mission is the ninth Synspective launch on Electron and that the satellite will support the Japanese company’s SAR imaging constellation over Japan. The company said that constellation provides data for urban development planning, construction and infrastructure monitoring, and disaster response.

Rocket Lab listed the launch as “NET 09:30 UTC” on its mission page, with local conversions including 9:30 p.m. NZST and 5:30 a.m. U.S. Eastern Time. The company also said its livestream would start about 30 minutes before liftoff. (synspective.com) Synspective’s April 30 notice gave May 22 UTC as the scheduled opening of the launch opportunity but did not fix a narrower time in that release. The company said the mission could be postponed or canceled because of weather conditions or complications and directed readers to Rocket Lab’s upcoming missions page for updates.

On the mission page, Rocket Lab said another 18 missions were already booked to deliver the rest of Synspective’s constellation before 2030. (rocketlabcorp.com) Synspective said in a later September 2025 release that it had expanded its partnership with Rocket Lab through an additional 10 dedicated Electron launches. In that statement, Synspective founder and Chief Executive Motoyuki Arai said Rocket Lab’s schedule flexibility and track record had supported the company’s constellation deployment, while Rocket Lab founder and CEO Peter Beck said regular launch access was essential to the buildout of the StriX network. (synspective.com) ### What orbit and mission profile did Rocket Lab disclose? Rocket Lab said “Viva La StriX” is planned for a 572-kilometer low Earth orbit with an inclination of 44.8 degrees. (rocketlabcorp.com) The company identified the flight as a dedicated Electron mission rather than a rideshare. The Mahia Peninsula site is Rocket Lab’s Launch Complex 1, the same New Zealand spaceport the company has used for Electron missions for commercial and government customers. Synspective’s April 30 notice also identified Mahia as the launch location. (synspective.com) ### What should readers watch next? Rocket Lab said the next public milestone is the webcast, scheduled to begin about 30 minutes before the 09:30 UTC launch target on May 22. The company also said launch images and footage would be posted after a successful mission, while Synspective said further schedule updates would appear through Rocket Lab’s mission listings if conditions force a delay.
