US-K spy^Wmapping satellite and Tsyklon-2 booster
Note: Still needs to be updated for NFPP 0.30 and KSP Interstellar 0.8.x; depends on NFPP 0.2x and KSP Interstellar 0.7.4 for now.
Forum thread (ctrl+f US-K)
The US-K spy^H^H^Hterrain mapping satellite combines height mapping, slope mapping, biome mapping, and anomaly mapping into one satellite. Its on-board nuclear reactor provides ample* power for the SCANsat antennae & induction thruster and can be jettisoned into a safe disposal orbit once its fuel supply is depleted.
The accompanying Tsyklon-2 launch vehicle can, with proper handling, get the US-K into orbit without creating orbiting debris.
