M-3SII missions
« on: 06/24/2019 06:31 pm »
In the 1980s the original M-3 launch vehicle was upgraded to increase performance. The resulting launch vehicle M-3SII was used to launch Japan's contributions to "the Halley armada" in 1985.

M-3SII-1 - January 8, 1985

This was the first flight of the M-3SII vehicle and it launched the MS-T5 interplanetary probe (renamed SAKIGAKE after launch) on an intercept trajectory to comet Halley.
