---

PT Telek. Indoneisa Tbk satellite from Reshetnev/Thales using Ekspress-1000N. Mass 1903 kg. 32 C-band, 10 Ku-band. Planned GEO 118E,but stranded in low orbit because of Briz failure.

Briz mass after failure estimated by Ted Molczan to be 14108 kg full 2370 kg dry, with DTB still attached, plus a 100 kg payload adapter.

Also known as 'Naro Scientific Satellite', nalogwahag-wiseong (

\uni{ 나로과학위성)}{ }

STSAT-2C carries geodesy, science and technology experiments. SIze is 0.76 x 1.02 x 1.16m, mass 100 kg. Planned orbit 300 x 1500 x 80

Stage 2 is 86.2 kN thrust, 250s ISP and 25s burn time according to wikipedia; 58s burn time from other sources. Estimate 4010m/s.
