Suisei

 1985-073A

---

The Planet A spacecraft was named Suisei (`Comet',

\uni{ 彗星)}{ }

once it was launched into solar orbit on a trajectory to pass close to comet 1P/Halley.

Mass of Suisei was 135 kg full 125 kg dry. Size is 1.40m dia 0.70m high. (1.7m high with dish; 2.4m from top of dish to bottom of MGA).

Escape trajectory was 11.374 km/s. The launch was a direct ascent trajectory with M3B and KM-P burns at stage 2 apogee. M-3B had an Isp of 292.9s, estimated dV 4.393 km/s KM-P was 1.23m long 0.79m dia with mass 461 kg full, 41 kg empty. It had 32 kN thrust for 36s with Isp of 287.4s, implying a delta-V of 3.4 km/s.

Suisei passed 150000 km from Halley. KM-P passed 200000 km from Halley.

Deep space tracking station Usuda.
