RAISE-4 (RApid Innovative payload demonstration Satellite-4) is a Japan Aerospace Exploration Agency (JAXA) satellite for on-orbit demonstrations of 15 demonstration components and equipment selected by public solicitation. The satellite will be operated in response to requests from the demonstration theme proposers, and will provide experimental data of the demonstration devices and environmental data during the experiments.
6 of the demonstration payload, as well as as well as 4 cubesats originally planned to ride on the same launch vehicle, are re-flight of those planned for RAISE-3, which failed to reach orbit in October 2022.
The launch vehicle was switched from Epsilon-S to Rocket Lab's Electron due to continuous testing problems with the Epsilon-S' 2nd stage motor. The original 8 hitch-hiking cubesats will be launched on another Electron rocket later.
Rocket Lab is an American aerospace manufacturer with a wholly owned New Zealand subsidiary. The company develops lightweight, cost-effective commercial rocket launch services. The Electron Program was founded on the premise that small payloads such as CubeSats require dedicated small launch vehicles and flexibility not currently offered by traditional rocket systems. Its rocket, the Electron, is a light-weight rocket and is now operating commercially. The company is also producing a variety of spacecrafts and spacecrafts components.
