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.
Sun-Synchronous OrbitDEAR-5 is a commercial in-orbit payload and micro-gravity experiments hosting spacecraft developed by Chinese commercial company AZSPACE for various civilian customers, with capability to carry a maximum of 300 kg of payload for up to 1 year in orbit.
