JAXA is preparing a rideshare mission carrying eight independent spacecraft, including educational small satellites, an ocean‑monitoring satellite, a demonstrator for ultra‑small multispectral cameras, and a satellite equipped with a deployable antenna that uses origami‑style folding to compact itself and then expand to 25 times its stowed size. These satellites were originally scheduled to launch with RAISE‑4 on a Japanese Epsilon‑S rocket, but the Epsilon‑S program experienced major delays following multiple test‑firing failures. As a result, the rideshare has been reassigned. The eight satellites are: MAGNARO‑II, KOSEN‑2R, WASEDA‑SAT‑ZERO‑II, FSI‑SAT2, OrigamiSat‑2, Mono‑Nikko, ARICA‑2 and PRELUDE
