The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, spacecraft safely arrived at the Rocket Lab Launch Complex 1 (LC-1) on the Mahia Peninsula of New Zealand ahead of its launch. The launch window opens May 31 and extends through June 22. Rocket Lab completed the launch rehearsal, and with the spacecraft now at the launch site, will begin payload integration with the Electron rocket and Photon spacecraft bus.
