This small scale, high function scientific satellite was developed as a companion small scale probe that can be launched at a very low cost together with large scale probes using the surplus strength of the large scale rockets. The aim of the project is to carry out small scale, high frequency science and engineering missions, train young scholars and engineers, and verify next generation technology in orbit.
The Reimei small scale, high function scientific probe was developed as a companion small scale probe that can be launched at a very low cost together with large scale probes using the surplus strength of the large scale rockets. The goals for downsizing and lowering costs include:
1. Verifying next generation technology in orbit.
2. Training young scholars and engineers.
3. Accomplishing high frequency, small scale science and engineering missions.
