Sputum result 2 (sputum result 2 ごう) is a man-made satellite for the technical examination that Tokyo University Institute of Space and Aeronautical Science (Institute of Space and Astronautical Science in the back, the current Japan Aerospace Exploration Agency space science study headquarters) developed. The development name is MS-T2.

Purpose
Our plane was developed for the purpose of the launching performance test of the M-3C rocket which was the all the paragraphs solid-propellent rocket which Institute of Space and Aeronautical Science developed and the examination of the posture control system of the satellite with the magnetic torquer. I posture controlled it, but the satellite of the laboratory of conventional space was expected only by a spin stability method when more highly precise observation was enabled by using a magnetic torquer method together. This method was adopted in following scientific satellite "たいよう".
Operational
Our plane was launched in the M-3C rocket first unit in (JST) at 14:00 on February 16, 1974 by the Kagoshima outer space observatory and was cast into perigee an altitude of 288km, apogee an altitude of 3,238km, the orbit of orbit angle of inclination 31.2 degrees.
I tested it in orbit until March 1 and finished use because the life of the silver oxide cell which was a power supply ran out.
On January 22, 1983, I broke into the atmosphere and became extinct.
