Description
Just both the avionics and propulsion module of the HTV bolted together (and also connected) to form the complete service module. On top, this set of electrical boxes will not allow your cargo to get lost in the vastness of space (an obvious pun of Lost in Space). There is also no need to worry about power supplies as the avionics module has its own solar panels. The propulsion module also protects your cargo from direct sunlight and space dust.
A mod rocket called HTV service module. Built with 14 of the finest parts, its root part is HTV.Avionics.
Built in the VAB in KSP version 1.12.3.
