[5] The primary payload of Shin'en consists of six university-built computers, which were to be tested in interplanetary space for robustness against the radiation and extremes of temperature.

Three other student spacecraft; Waseda-SAT2, K-Sat and Negai ☆ were also launched, however they separated from the rocket whilst it was still orbiting the Earth.

The launch was conducted by Mitsubishi Heavy Industries on behalf of the Japan Aerospace Exploration Agency.

The terminal countdown began at 11:30 UTC on 17 May and by 15:28, the loading of cryogenic propellant into the rocket's first and second stages had been completed.
