ISAS's Radio Exploration Satellite (REXS) was launched in 1972 and renamed Denpa (Radio wave). It studied the ionosphere and lower magnetosphere but failed after 3 days. Switch on of the EBA caused electrical discharges which toasted the spacecraft encoder. The radio beacon continued to operate until May 1973. REXS was a 70 kg, octagonal cylinder 0.68 h 0.71 dia with three 2m antennas.
M-4S-2 Mass of stage 4 plus payload is 525 f 145 em. Prop mas 380 kg. Payload mass 75 kg implying M-40 is 450f 70 em. Isp 276.0s?

Atmosphere Explorer D (Explorer 54) was launched on 1975 Oct 6 at 0901 by a Delta 2910 from Vandenberg. It entered a 126.9 min, 155 x 3816 km x 90.1 deg orbit after a single second stage burn. However, it operated until 1976 Jan 29 when its power supply failed, disabling the solar arrays. The satellite reentered on 1976 Mar 12.
Mass was 674 kg with 168 kg prop.
The MRMU released neon gas to simulate outgassing, and the returning gas was measured by NACE, PSA and PSB to study self-contamination.
