Rocket Lab launches Japanese radar satellite into orbit on Sept. 1

Rocket Lab is scheduled to launch a Japanese Earth‑observing radar satellite into orbit early Tuesday morning, September 1. The launch will take place from the company’s Launch Complex 1 at the Mid‑Atlantic Regional Spaceport in Virginia, using its Electron rocket.

The mission will carry a radar payload designed for high‑resolution mapping of the planet’s surface, a capability that will support a range of scientific and commercial applications. The launch window opens at 02:00 UTC, and the flight will be broadcast live, allowing viewers worldwide to follow the ascent and deployment of the satellite into its designated orbit.

Once the satellite reaches orbit, it will begin its mission to provide detailed radar imagery, contributing to Japan’s growing portfolio of space‑based Earth‑observation assets. The successful launch is expected to enhance the country’s ability to monitor environmental changes and support disaster response efforts.
