RAISE and Shine: Electron Debuts on First of Two Missions for JAXA

Rocket Lab’s Electron lifted off successfully on December 13, 2025, at 03:09 UTC, from Launch Complex 1 in New Zealand. The mission, named RAISE and Shine, carried the Japanese technology demonstration satellite RAISE-4 toward its planned 540 km sun-synchronous circular orbit.

The flight marked another operational success for Electron in a year of high cadence. Rocket Lab has now flown 18 missions in 2025, including 15 orbital launches and three suborbital flights.

RAISE-4 is a single technology demonstration satellite developed under JAXA’s Innovative Satellite Technology Demonstration Program. It carries eight experimental payloads designed to validate new components, sensors, and in-orbit systems for Japanese industry, universities, and research institutes.

This is the first mission contracted directly between JAXA and Rocket Lab, marking a new step in Japan’s strategy for small payload access to space. The launch is part of a two-flight agreement that will continues in early 2026. It follows the pause in Japan’s own small launcher operations after the Epsilon rocket setback.

The shift highlights JAXA’s need for a reliable cadence to keep its technology demonstration program moving forward.

RAISE, JAXA rideshare mission for innovative technologies

RAISE-4 (RApid Innovative payload demonstration SatellitE-4) is a 110 kg spacecraft carrying eight test articles selected through JAXA’s national open call. Six of these are reflights from RAISE-3, giving their developers a second opportunity to reach orbit after the 2022 Epsilon rocket failure.

Within this suite of experiments, the GEMINI demonstration advances onboard processing by integrating a commercial off-the-shelf GPU into a constrained smallsat environment. Its goal is to validate the direct in-orbit handling of imaging and sensor data, reducing downlink loads and supporting faster autonomous operations.

Efforts to enhance post-mission disposal are embodied in the D-SAIL experiment, a deployable membrane designed to increase atmospheric drag without compromising structural stability. The test will characterise deployment behaviour and drag performance to refine debris mitigation strategies for future LEO missions.

Progress in compact manoeuvring systems is explored through KIR-X, a propulsion and attitude control concept inherited from the earlier RAISE-3 design. The investigation aims to quantify the fine pointing and small delta-v capability within a microsatellite-class bus to meet the rising agility demands.

Rocket Lab and JAXA, a partnership for launch continuity

JAXA’s Innovative Satellite Technology Demonstration Program provides flight opportunities for components, instruments, and small satellites developed by Japanese industry, universities, and research institutions. Its goal is to accelerate technology validation and strengthen Japan’s growing smallsat ecosystem, with RAISE-4 serving as the latest platform for publicly selected demonstration themes.

That continuity was disrupted in October 2022, when RAISE-3 was lost during the Epsilon 6 launch failure. Further delays to the upgraded Epsilon S architecture then threatened the program’s cadence and the timely validation of new technologies.

To preserve momentum, JAXA selected Rocket Lab’s Electron to secure a predictable demonstration window for RAISE-4 and its reflight payloads. The decision marks the agency’s first directly contracted mission with Rocket Lab and forms part of a two-launch agreement extending into early 2026.

It reflects a pragmatic shift toward dependable commercial access to space while Japan refines its next-generation Epsilon S architecture. The arrangement ensures that industry, academic, and research partners can continue testing new technologies without interruption, establishing the pace that future RAISE missions will follow as the program moves toward the 2026 flight.
